How Entomology Supports Disaster Preparedness and Risk Planning
Disaster preparedness planning usually focuses on evacuation routes, emergency supply kits and shelter plans. Insects rarely make the list.
But after a hurricane or flood, insect populations aren’t waiting for communities to catch up.
Mosquito numbers spike. New breeding sites appear overnight. Disease risks increase. That’s why entomology plays a crucial role in emergency management planning.
By monitoring insect populations and identifying potential disease vectors, public health entomologists help officials anticipate risks and respond more quickly when disasters strike.
How Post-Disaster Conditions Affect Insect Populations
Insects respond quickly to environmental change. Standing water, debris and damaged infrastructure can alter insect populations dramatically — sometimes in a matter of days.
After a disaster, several environmental shifts often occur:
Standing water accumulation Flooding and storm runoff create ideal mosquito breeding sites.
Debris and waste buildup Storm damage can attract flies and other nuisance insects.
Disrupted pest control programs Local mosquito control operations may pause during emergencies.
Wildlife displacement Changes in animal movement can alter how insect-borne diseases circulate.
These changes don’t automatically lead to disease outbreaks. But they can increase the likelihood that disease-carrying insects become more common in affected areas. Monitoring these shifts helps emergency planners stay ahead of potential risks.
How Officials Monitor Insect Risks After a Disaster
Tracking insect populations is a key part of public health preparedness after a disaster.
After a major storm or flooding event, public health teams often increase monitoring efforts to understand whether mosquitoes and other disease-carrying insects are multiplying, spreading or appearing in new areas.
These programs typically involve several steps:
Mosquito trapping Scientists deploy traps to measure population size and activity.
Species identification Entomologists determine which mosquito species are present, since disease risk varies by species.
Pathogen testing Collected insects may be tested for diseases such as West Nile virus or dengue.
Breeding site mapping Standing water and other habitats are documented to guide control efforts.
Data sharing Findings are communicated to local health departments and emergency planners.
This information helps officials decide whether mosquito control interventions are necessary and where they’ll have the greatest impact.
In many cases, surveillance data allows communities to respond early rather than reacting after disease transmission increases. That kind of early response depends on the expertise of one key figure: the public health entomologist.
The Role of a Public Health Entomologist
A public health entomologiststudies insects that affect human health and works closely with government agencies during emergency management planning and disaster response. Their work often blends field research, laboratory analysis and collaboration with public health teams.
During disaster preparedness planning and recovery efforts, a public health entomologist contributes in several ways:
Population monitoring
Tracking how mosquito or tick populations change after environmental disruption
Risk assessment
Determining whether insect population shifts could increase disease transmission
Control strategy guidance
Advising agencies on targeted mosquito management methods
Surveillance coordination
Working with local mosquito control districts to collect and analyze data
Public communication
Helping communities understand how to reduce insect exposure after disasters
By translating insect data into practical recommendations, these scientists help emergency teams make faster, more informed decisions.
Real-World Example: Mosquito Surges After Hurricanes
Hurricane Irma offers a strong real-world example of why entomology matters in disaster preparedness planning. In a 2024 study on mosquito populations in Miami-Dade County, researchers found mosquito numbers increased sharply after the storm.
In the weeks that followed, researchers captured roughly seven to eight times more mosquitoes than they did during baseline periods before and after the hurricane. The increase happened quickly, with mosquito numbers rising within about a week as post-storm conditions created new breeding opportunities.
This kind of data lets public health teams move beyond guesswork. With vector surveillance in place, officials can track post-disaster increases in mosquito populations, identify which species are present and determine where targeted control efforts are most needed.

Ever seen one of these up close? You might not realize it, but this little insect is one of the world’s most successful — and most troublesome — invaders.
Meet the Asian Tiger Mosquito (Aedes albopictus)
If nature had a supervillain the size of a sesame seed, it would look exactly like the Asian tiger mosquito (also known by its Latin name, Aedes albopictus).
You can recognize an Asian tiger mosquito by the single white stripe running down the center of its back and its zebra-striped legs. It’s tiny — typically two to ten millimeters (1/12 to 3/8 of an inch) — but don’t let its size fool you. The Asian tiger mosquito is part of the Culicidae family, which includes many species capable of transmitting dangerous viruses.
How Did the Asian Tiger Mosquito Spread?
The first group of Asian tiger mosquitoes traveled from Japan, Korea, southern China and Southeast Asia into the United States on shipments of used tires and decorative bamboo in the mid-1980s. But this pest didn’t just immigrate. It moved in, unpacked its bags … and went rogue.
Where Do Asian Tiger Mosquitoes Live?
Since its arrival, the Asian tiger mosquito has established itself across much of the South, Midwest and parts of California, as well as dozens of countries in Europe, Africa, South America and Oceania.
Here’s a comparison showing their quick spread alongside another well-known vector:

How Has the Asian Tiger Mosquito Spread So Fast?
Global warming. Long international travel. Harsh winters. Hot summers. No problem if you’re an Asian tiger mosquito … if there’s a teaspoon of water around.
This invasive species is a resilient hitchhiker and can breed in any container that includes standing water. Think flowerpots, gutters, plastic debris, decor and bottle caps. That planter you forgot about? The tiger mosquito didn’t.
While most mosquitoes are most active at dawn and dusk, the Asian tiger mosquito works a full day shift. They thrive in:
Shaded yards
Patios
City landscapes
This makes suburban, semi-urban and urban environments an ideal habitat for them, and they easily reinvade after they’ve been controlled — even in the winter.
How Do They Interact With Other Invasive Species?
Asian tiger mosquitoes don’t politely coexist. They displace native mosquito species, outcompeting them and becoming the dominant biter in many regions.
The yellow fever mosquito was once dominant in the Mediterranean and southeastern U.S. Now it’s losing ground in areas where Asian tiger mosquitoes have taken over.
What Kinds of Diseases Do Asian Tiger Mosquitoes Carry?
Vector-borne diseases cause over 700,000 deaths a year, and the Asian tiger mosquito has built quite a portfolio. This striped pest can spread multiple viruses, causing debilitating diseases for humans, cattle and pets. These include:
Public health teams can monitor mosquito activity, apply gene technology, watch for new cases and remind people to protect themselves. But the tough part is how fast these mosquitoes come back. The minute rain hits and water pools, their eggs hatch and the population surges all over again.
Why Are Tiger Mosquitoes So Hard to Control?
Tiger mosquitoes are hard to control for public health officials because of three key factors:
Tiny, scattered breeding sites The mosquitoes’ larvae develop in very small containers, and many breeding sites are on private property and hard to locate. This makes traditional larviciding and fogging less effective.
Sticky, resilient eggs Tiger mosquito eggs are extremely resilient, able to survive drying and cold and remain viable until conditions improve. This makes their ability to overwinter greater than other species. They also adhere to container surfaces, so draining or rinsing may not remove them entirely.
Aggressive, all-day feeding Because this mosquito is active all day, traditional evening insecticide fogging misses many active adults preying when the sun is up. Their close association with homes and gardens increases human contact.
How Can You Manage the Asian Tiger Mosquito?
Managing the Asian tiger mosquito usually requires coordinated community action. Here’s what you can do:
The tiger mosquito can dodge sprays, survive droughts and outsmart the weather, but it can’t outsmart a coordinated community.
Key Takeaways: The Asian Tiger Mosquito
Here’s a quick recap of what we’ve learned about the Asian tiger mosquito:
Small size, big attitude This little invader has made itself at home around the globe and loves hanging out close to humans in backyards, patios and cities.
If it holds water, it’s a nursery Its eggs glue themselves to containers and aren’t really affected by droughts and freezes.
A relentless biter While other mosquitoes are most active at dusk and dawn, this one works a full shift. The Asian tiger mosquito bites all day and multiplies fast after even light rain, sometimes even in winter.
A tough competitor This species pushes many native mosquitoes aside and carries debilitating diseases that can affect people and pets. The best defense? A united neighborhood and zero standing water.
With a little awareness and routine prevention, we can all help keep this deadly troublemaker in check.

What if the insects we’ve been trying to kill could actually save our lives?
Mosquitoes, ticks and fleas spread diseases to hundreds of millions of people worldwide each year. But scientists are turning some of these pests into lifesaving tools, using them to detect cancer, stop disease transmission and improve human health in ways that might surprise you.
In this article, we’ll explore the role of insects in medicine and other ways they can help us fight disease. We’ll also introduce medical entomology: the study of how insects transmit disease to humans and animals. If you’re fascinated by insects and want to make a real impact on public health, medical entomology can provide some unique opportunities.
Social Insects Are Disease Control Experts
Ants, termites and bees are surprisingly good at public health management. They live in tight quarters, yet they’re constantly keeping disease in check. And they offer real-world insight that can inform the use of insects in medicine research.
Take, for example, how ants prevent disease in their colonies:
Grooming
Ants clean each other constantly. That small exposure to germs can act like a natural vaccine, helping the colony build immunity. Food sharing can also have the same collective immunization effect.
Social Distancing
Ants seem to know instinctively that sick and healthy colony members should stay apart. They practice social distancing by:
Are you the friend that’s always carrying a bottle of hand sanitizer? If so, you’ve got more in common with ants than you think.
Ants secrete antimicrobial compounds from their metapleural glands (MGs): a fascinating feature.But what’s even more interesting is that when researchers exposed ants to fungal spores, the ants ramped up their MG secretions, meaning they actually control this defense mechanism.
Frequent cleaning? Social distancing? Antimicrobial use? These sound a lot like best practices from the COVID-19 pandemic … but insects were doing them first. Who knows what other disease prevention lessons we can learn from the insect world?
Bees Can Smell Disease
Yes, bees can smell fear — or at least the pheromones we release when we experience it. But that’s not the only thing they can detect.
Researchers attached electrodes to the odor-processing area of the bees’ brains. They then sprayed aerosolized mixtures simulating the breath of a healthy subject and a lung cancer patient on the bees’ antennae. The bees could tell the difference more than 90% of the time.
Not only that, they could distinguish between types of lung cancer: non-small cell versus the more aggressive small cell variety.
But bees have been providing benefits beyond pollination for years. They can also detect high acetone levels linked to diabetes. Bees’ sense of smell could be a valuable diagnostic tool in medicine.
Edible Insects Provide Nutritional Benefits
Insects are plentiful, high in protein and other nutrients, and appetizing. (Okay, there may be some differences of opinion on that last one.)
Bioactive compounds like antioxidants, anti-inflammatories and antimicrobials that protect against diseases like cancer and heart conditions
Omega-3 and Omega-6 fatty acids, which support heart health
A prebiotic that promotes beneficial gut microbes like Lactobacillus and Bifidobacterium, improving digestive health
Insect-based diets also have a much smaller environmental footprint and could help reduce food insecurity. Around the world, some cultures already eat:
Crickets, grasshoppers and locusts
Beetles
Mealworms
Caterpillars
Cicadas
Termites
Laboratory-Modified Insects Will Bite, But Won’t Make You Sick
When a mosquito sticks its mouthparts into our skin to feed, it can leave behind a variety of nasty diseases. But what if it wasn’t carrying that disease in the first place?
One research team infected female mosquitoes — the ones that bite — with Wolbachia bacteria, preventing them from carrying the dengue virus. Scientists are now working to spread this disease-preventing bacteria to larger mosquito populations.
The same approach is being tested on sandflies to combat leishmaniasis, a disease that:
Can be fatal if not treated promptly
Comes from Leishmania parasites transmitted in sandfly bites
Researchers are altering the sandfly’s gut microbiome so the parasite can’t grow within it. No Leishmania, no disease.
Both pests will still live up to their reputation as bloodsuckers, but their potential as disease vectors can be greatly reduced.
Parasitic wasps lay their eggs inside a variety of insects. Later, the wasp larvae eat the host insect from inside.
If you’re intrigued by these insect discoveries, medical entomology credentials may be your next step.

Imagine a killer slipping through a cracked window and landing on your arm without you noticing. By the time you swat, it’s already vanished. Some species will strike again quickly if disturbed, while others pause before their next bite.
Now imagine that this tiny assassin has a million similarly sneaky relatives that cause more than 700,000 deaths each year.
Mosquitoes, ticks, blackflies and other vectors (disease-carrying insects) may be small, but in public health, they’re a massive problem — and their reach extends far beyond your backyard.
In this article, we’ll take a deep dive into the new technologies transforming medical entomology and the fight against vector-borne diseases.
What Do Medical Entomologists Do?
Medical entomologistsare the detectives, scientists and strategists (sometimes all in one day) who study how insect vectors spread disease, and, most importantly, how to stop them.
How Are They Using New Technology in Medical Entomology?
Insect nets, jars and microscopes are traditional go-to tools for medical entomologists, but new technology has made their job a whole lot easier. Medical entomologists are now using:
Drones
AI-powered traps
Genetic engineering
Portable diagnostics
GIS mapping
For example, mosquitoes spread diseases like malaria and Zika. Ticks are a big concern for Lyme disease. Blackflies can transmit river blindness in Africa, and tsetse flies are known for spreading sleeping sickness. These are only some of the vectors out there — each with its own challenges, and researchers are finding new ways to tackle them.
#1 Drone Technology
Imagine slogging through water or high grass in remote, sometimes dangerous places to collect specimens or deploy treatments. Drones today can do many of the same tasks (while avoiding the mud-soaked boots and insect bites). Drones help fight pests that destroy crops, ecosystems and insects that carry disease by:
Releasing genetically engineered insects for sterile mating or population suppression
The University of Florida, for example, uses drones to find mosquito breeding sites in Florida wetlands for targeted control.
#2 AI-Powered Smart Traps
In the past, catching and identifying insects meant lugging traps back to a lab, sifting through piles of specimens … and hoping none escaped before identification.
Smart insect traps — powered by artificial intelligence and in development for future use — could do much of the heavy work soon. Vectors will have a harder time remaining undercover when these traps can:
Identify insects instantly
Send data straight to the cloud
Continuously log activity
Trigger an alert if a dangerous species shows up
Need a real-world example? This new smart trap automatically counts mosquitoes in the field and transmits live updates.
#3 CRISPR: Genetic Engineering
What if we could create a superbug to fight other bugs … and save lives in the process? This isn’t science fiction: Scientists can now use CRISPR-Cas gene editing to change an insect’s genes.
For example, scientists can deploy modified male mosquitoes whose offspring never reach adulthood. Another method allows them to introduce genes (or bacteria like Wolbachia) that prevent mosquitoes from carrying viruses like dengue or Zika.
Researchers are also testing CRISPR on kissing bugs to curb the spread of Chagas disease and on ticks to reduce Lyme disease transmission. Some engineered insects are designed with self-limiting traits, so the changes fade out after a few generations.
Still, real-world deployment has seen uneven results. Concerns about ecological impacts, regulation and variable field results mean that CRISPR-based approaches are still undergoing careful testing.
#4 Portable Diagnostics
If an outbreak is already brewing, however, every second counts. Medical entomology field teams can now get answers through portable tests that are small enough to carry around, including:
LAMP (Loop-Mediated Isothermal Amplification)technology, a fast way to detect DNA and RNA, often with a simple color change on a test strip
LAMP assays (developed for rapid detection of the dengue virus) let field teams identify infections in under an hour. It’s like having a mini lab in your backpack!
#5 GIS Mapping and Machine Learning
Think of GIS (Geographical Information Systems) as a detailed forecast. This technology layers satellite images, breeding site surveys, climate data and human movement patterns into a real-time map. Machine learning then scours that picture for patterns people can’t see—such as blackfly surges after a rainstorm or a tick outbreak.
UF’s Florida Medical Entomology Lab is already using this technology. Our field teams can predict where vectors will appear next and stop potential outbreaks before they spread.
Research published in PNAS shows that deep learning and computer vision are pushing medical entomology even further, using sensor-based monitoring, image recognition and automated trait detection to speed up decision-making. These advances are launching new opportunities for entomology enthusiasts with a special interest in mathematics, programming and AI.
#6 Radioactive Tracking
Radioactive materials work like invisible GPS tags to track insects. This technology can trace every part of an insect’s journey and its lifespan. The International Atomic Energy Agency, for example, uses radioisotopes to mark and track tsetse flies in Africa.
New Technologies in Medical Entomology: What You Need to Know
Medical entomology is evolving fast, and medical entomologists are constantly upgrading technology to stop diseases before they spread. Let’s recap a few key points:
Drones, AI traps and CRISPR can target vectors precisely.
Portable tests can deliver results in under an hour.
GIS and machine learning predict outbreaks before they happen.
Radioisotopes track insect movement.

Have you ever felt pulled in two very different career directions — like wanting to be both a hair stylist and a lab technician?
Okay, that’s a far-fetched example, but humor us. At first glance, the pairing might seem impossible. But careers that appear unrelated can sometimes overlap, especially when science is involved.
Here’s a real-world example: public health and entomology. One field focuses on improving human well-being, the other centers on the close study of insects. Together, they create a unique, vital discipline: public health entomology. Specialists in this field — people who study insects with a focus on human health — work at the intersection of bugs and people, tackling everything from global disease outbreaks to local pest management.
If you’re fascinated by insects (especially those that spread disease) and want a career that combines science, problem-solving and community impact, public health entomology could be your ideal path.
What Is Public Health Entomology?
Public health entomology is the study of insects (like mosquitoes, ticks and flies) that directly affect human health. These insects aren’t just annoying; they can spread serious diseases such as West Nile virus, dengue fever and Lyme disease.
Public health entomologists (often known as medical entomologists) study the life cycles, habitats and behaviors of insects to develop strategies that prevent disease transmission and protect communities before outbreaks occur.
How Do Entomologists Protect Public Health?
Medical entomologists aren’t just observing insect behaviors. They’re on the front lines, keeping communities safe from the chaos that six- and eight-legged critters could cause if left unchecked.
So, how do they do it? These professionals:
Research how insects spread diseases
Test new ways to control populations
Collaborate with public health officials to keep communities safe
Their work often combines field studies and laboratory research, spanning government agencies, hospitals and educational programs.
Top 5 Careers in Public Health Entomology
Careers in public health entomology involve a wide range of roles, from hands-on fieldwork to community education and policy consulting. Each role plays a critical part in protecting people from vector-borne diseases and improving our understanding of insect behavior.
Here’s a closer look at five key career paths.
Career #1: Public Health Entomologist
Public health entomologists are essential for protecting communities from insect-borne diseases. They study insects like mosquitoes and ticks, tracking populations, observing habitats and analyzing behaviors to understand how these bugs transmit illnesses.
Developing strategies to control vector populations
Educating communities on prevention
Collaborating with healthcare professionals, scientists and government agencies
This role forms the foundation for more specialized careers in the field, offering a mix of fieldwork, lab research, problem-solving and public health impact.
Career #2: Research Scientist
Research scientists in entomology focus on uncovering the biology, behavior and disease transmission patterns of insects. Unlike public health entomologists, who blend fieldwork, community engagement and applied prevention, research scientists dive deep into experiments — both in the lab and the field — to discover new insights about disease vectors.
Key responsibilities include:
Designing and conducting controlled experiments
Collecting and interpreting data on insect behavior and pathogen transmission
Publishing findings in scientific journals to inform the scientific and public health community
Many research scientists work for universities, government agencies like the Centers for Disease Control and Prevention or private research organizations. This role often requires a master’s or doctorate in entomology, biology or public health and is central to developing evidence-based strategies for disease prevention.
Career #3: Vector Control Specialist
While research scientists focus on how insects spread diseases, vector control specialists work to reduce populations of disease-carrying insects to lower the risk of outbreaks. Their work blends fieldwork and data analysis using tools such as:
Traps
Insecticides
GIS mapping
Population monitoring
Some also take part in community outreach, helping residents understand why and how they should carry out control methods. Vector control specialists often work for local or state health departments, mosquito control districts or international health organizations.
Career #4: Public Health Educator
Public health educators translate scientific research into practical guidance for the public. Their “students” include:
Community members
Schools
Healthcare organizations
Local governments
Educators design campaigns, run workshops, create educational materials and develop school programs to prevent insect-borne illnesses. Their goal is to raise awareness and change behavior in diverse populations.
Career #5: Entomology Consultant
If your interests lean more entrepreneurial, consulting can be a rewarding public health entomology path. Consultants use their expertise to advise clients on insect control and disease prevention strategies, in areas like:
Government: Guiding public health policy and outbreak response
Corporate: Helping industries minimize vector risks in operations or products
Non-profit: Supporting community health programs and educational campaigns
How to Prepare for a Career in Entomology
If one of these career paths sounds like a match for you, you’ll need a strong foundation in biology and entomology. Most entry-level positions require a bachelor’s degree in entomology, biology or a related field. Advanced roles, like research scientist or consultant, typically call for a master’s or doctoral degree.
At the University of Florida, we offer four distinct graduate entomology specializations:
You can choose from a 30-credit master’s degree in one of our specializations or a 15-credit graduate degree. Both are entirely online, and either option allows you to focus on courses that matter to your future career, like Advanced Mosquito Biology.

Public health initiatives include efforts to warn people of the dangers of smoking, heart disease and obesity. In many cases, simply informing the public of a problem is enough to mitigate it. However, not all problems can be solved with a persuasive pamphlet. Transmitted by insects, some of the world’s most infectious diseases can spread…
When you hear the prefix “zoo,” it probably takes you back to childhood trips, eagerly watching some of your favorite four-legged creatures. You might not be familiar with the term zoonotic diseases, but you’ve likely guessed it has something to do with animals — and you’d be right! What Are Zoonotic Diseases? Zoonotic diseases are…
Ticks. They’re creepy, they’re crawly — and if you’ve ever gone hiking, you’re probably familiar with the idea of doing a “tick check” afterward. You may have even Googled things like “how to remove a tick” — just in case. Known for carrying and transmitting Lyme disease, these bloodsucking arachnids have earned a notorious reputation.
But how did ticks evolve to rely on blood for survival? And how are these adaptations informing today’s research in entomology and disease ecology?
Let’s find out.
How Have Ticks Evolved?
According to fossil records, Ixodidae—the order today’s hard ticks belong to—emerged during the Cretaceous period, about 100 million years ago. (So yes, they likely fed on feathered dinosaurs.)
And while ticks are arachnids, that doesn’t make them spiders. Sure, they have eight legs like their spider cousins, but their biology, behavior and ecological roles are quite different.
Tick Classification
Ticks are classified into three families: Ixodidae (hard ticks), Argasidae (soft ticks) and Nuttalliellidae (a rare, ancient group with only one species).
The earliest true ticks were already obligate blood-feeders, meaning they needed blood to survive. But before they evolved into the highly specialized parasites we know today, their ancestors (free-living mites), likely led a very different lifestyle.
These ancient relatives probably scavenged organic material or fed on decomposing insects in the soil. Over time, they evolved into blood-feeding ticks, a major shift likely driven by access to a more consistent and nutrient-rich food source: vertebrate blood.
Why Did Ticks Switch from Scavengers to Blood-Feeders?
Ticks transitioned from scavenging to blood-feeding because blood is a more nutrient-rich and reliable food source. This adaptation gave them a powerful survival advantage and supported their evolution into successful parasites.
But it wasn’t just about easy calories. Other evolutionary factors helped hematophagy (blood-feeding) become ticks’ go-to survival strategy:
Access to new hosts Once ticks began feeding on live animals, their dining options expanded. Birds, reptiles and mammals all became mobile food sources.
Greater mobility and survival Ticks that could hitch a ride on their hosts were able to travel farther and settle into new habitats, increasing their chances of survival and global spread.
Gradual specialization This evolutionary transition didn’t happen overnight. Some ancestral mites may have started on fluids from wounds or soft tissue. Over time, natural selection favored traits that made full blood-feeding more effective. Eventually, these adaptations gave rise to the distinct group we now recognize as ticks.
The Evolution of Tick Saliva and Mouthparts
Through years of evolution, ticks have developed characteristics that help them successfully thrive on blood. These specialized changes help them:
Cut through skin
Stay attached to their host
Remain unnoticed while feeding
Prevent blood from clotting
So how do they do it? Mostly, through two major adaptations: piercing mouthparts and anticoagulant saliva.
Piercing Mouth Parts
Ticks may not have sharp vampire-like fangs, but they do have something even more cunning: the ability to stay attached to their prey for hours (or even days) without being noticed.
That’s why their feeding structure evolved into a system called the capitulum, which includes three key components:
Palps: Sensory feelers that help the tick find a feeding site, but don’t pierce the skin
Chelicerae: Tiny, blade-like structures that saw through the host’s skin
Hypostome: A barbed, straw-like structure that anchors the tick and allows it to drink blood
Anticoagulant Saliva
Without the right chemicals on standby, it would be much harder for ticks to efficiently feed every time they find a host. That’s because vertebrates, like humans and other mammals, respond to injuries with clotting, inflammation and the feeling of pain.
So, over millions of years, tick saliva evolved into a complex chemical cocktail designed to quietly counteract those defenses. Inside that saliva, you’ll find:
Anticoagulants, to stop the host’s blood from clotting
Vasodilators, to open blood vessels wider to improve flow
Immunosuppressants, to quiet the immune system so the host doesn’t detect them
Pain blockers, to prevent itching, pain or other sensations around the bite

Forget lions and sharks: When it comes to global health threats, the mosquito packs the deadliest punch. These tiny insects cause over 700,000 deaths per year.
When you think of mosquito control, you might picture traditional methods like insecticides and larvicides. These techniques have helped safeguard our communities for decades, but today’s scientists are developing smarter, bolder and more sustainable solutions to keep mosquito populations in check (and out of our backyards).
Let’s take a closer look at how modern mosquito control techniques are evolving and why they matter.
New Mosquito Control Techniques: In the Lab
Traditional mosquito control relies on traps, repellents, misting and eliminating breeding sites. But today’s cutting-edge strategies start in the lab, where entomologists and public health scientists are pushing boundaries and investigating the biology, behavior and vulnerabilities of mosquito species.
Some key areas of research are:
#1 The Mosquito Microbiome
The mosquito microbiome is the community of bacteria living inside mosquitoes. While not every mosquito is out to infect us with pathogens, the ones who are can spread deadly diseases like malaria, dengue, Zika and yellow fever.
Research shows that changing a mosquito’s microbiome can reduce its ability to spread disease. Scientists are finding ways to introduce bacteria that block disease transmission, offering a more eco-friendly strategy for protecting human populations.
#2 Gene-Editing Technologies
This is another game-changer: Gene-editing tools like CRISPR-Cas have allowed researchers to create genetically modified mosquitoes that:
are resistant to carrying diseases
can’t reproduce successfully in the wild
These genetic approaches are promising, but it’ll take some extensive real-world testing before we can start sending mutant mosquitoes to battle their disease-laden counterparts.
New Mosquito Control Strategies: In the Real World
Research breakthroughs mean little unless they translate into practical and scalable solutions. That’s why field testing is so important: It bridges the gap between theory and impact.
Here are some of the newest mosquito control trends playing out in communities today:
#1 Sterile Insect Technique (SIT)
Building on a technique that was first used in agriculture, SIT uses radiation or genetic engineering to sterilize male mosquitoes.
Only female mosquitoes bite, but when sterile male mosquitoes are released into the wild, they mate with females, and no offspring are produced. Over time, this naturally lowers mosquito populations — without the widespread use of chemical pesticides.
Wolbachia bacteria are found naturally in about 50% of all insect species, including mosquitoes, fruit flies, moths and dragonflies. These bacteria aren’t harmful to humans, and they block viruses like dengue or West Nile from replicating inside mosquitoes.
Scientists are breeding mosquitoes with Wolbachia and releasing them into the wild. As they breed, they pass Wolbachia to their offspring, gradually lowering disease transmission rates.
This approach is a prime example of how entomologists are using nature to solve a problem while minimizing ecological disruption.
#3 Drone Technology and Smart Surveillance
Finding and controlling mosquito breeding sites is easier with drone technology and remote surveillance systems. These tools help scientists survey wetlands, marshes and urban areas to find mosquito hotspots, enabling faster and more targeted interventions and saving time, money and resources.
Some areas even deploy smart mosquito traps with acoustic sensors that identify mosquito species by their unique wing-beat frequencies. These traps can capture mosquitoes without damage and collect real-time data on mosquito populations, helping experts target control measures more efficiently.
Challenges in Implementing New Mosquito Control Techniques
Of course, even the most exciting new technologies face challenges:
Cost and access: Advanced techniques like gene editing require significant funding and technical expertise, making them less available in low-resource areas.
Public concerns: Releasing genetically modified mosquitoes—i.e., tampering with nature—raises ethical concerns for some communities.
Environmental impact: Even careful releases can behave unpredictably, and influences like climate, predators or human activity can affect the outcome.
This is why ongoing research, education and community involvement remain key to successful mosquito control programs—now and in the future.
Key Takeaways: What’s Next for Mosquito Control?
With continued innovation, mosquito control is becoming more sustainable, precise and impactful for global public health. Let’s recap what we’ve learned in this article:
Lab research is driving new mosquito control techniques, like microbiome manipulation and gene editing.
Wolbachia bacteria are nature’s virus blockers, lowering disease spread without harming ecosystems.
Drones and smart traps make mosquito surveillance faster and more precise.
Challenges remain, including costs, ethical concerns and environmental unpredictability, so careful planning and community support are essential.

Vector-borne diseases (VBDs) account for more than 17% of all infectious diseases worldwide, and their presence in Europe is growing. Climate change, global travel and urbanization are creating ideal conditions for disease-carrying vectors like mosquitoes, ticks and sandflies to spread.
Across Europe, vector-borne illnesses such as Lyme disease, West Nile virus, chikungunya and dengue fever are becoming more common and widespread. This rising risk has led to a coordinated push toward vector-borne disease preparedness, a public health strategy that combines surveillance, prevention, education and emergency planning to stop outbreaks before they start.
In this article, we’ll explore the main causes driving the spread of VBDs in Europe and examine how governments and communities are working together to monitor vectors and prevent future outbreaks.
What’s Driving the Spread of Vector-Borne Diseases in Europe?
Vector-borne diseases don’t spread in a vacuum: They’re shaped by our environment and how we behave within it. In Europe, several key factors are fueling the increased presence and persistence of vectors:
Climate change Warmer temperatures, heavy rainfall and even droughts are all changing familiar weather patterns. These shifts create ideal conditions for vectors to thrive. Milder winters allow more vectors to overwinter, and longer, warmer summers extend the breeding and transmission seasons.
Globalization With people flying between countries and cargo ships moving goods across continents, today’s interconnected world makes it easier for vectors — and the pathogens they carry — to travel. For example, a mosquito can hitch a ride on a plane or ship and end up in an entirely different country.
Urbanization As more people move into densely populated cities, the demand for housing and infrastructure grows. Unfortunately, many urban areas have poor drainage and water management systems, creating ideal mosquito breeding grounds. Crowded living conditions can also make it easier for diseases to spread once introduced.
Ecological disruption Deforestation and land development bring humans closer to natural vector habitats. Changes in land use, such as new farming practices or loss of biodiversity, can upset ecosystems and allow vectors to thrive and expand into new areas.
How Europe Monitors Vector-Borne Diseases
Getting ahead of vector-borne diseases starts with surveillance. Health authorities must know where vectors are and how they’re behaving. By tracking where vectors are found and how their populations change, officials can predict and prevent outbreaks.
Here are some of the teams making it happen:
European Centre for Disease Prevention and Control (ECDC)
The ECDC is an agency of the European Union dedicated to strengthening Europe’s defenses against infectious diseases. When it comes to vector-borne disease surveillance, it:
Conducts risk assessments to evaluate the potential for disease spread across the EU
Collects and analyzes vector data from member states to track patterns and emerging threats in near real time
Manages the European Early Warning and Response System (EWRS), which alerts public health officials when immediate action is needed
VectorNet: A Cross-Border Collaboration
VectorNet is a joint project between the ECDC and the European Food Safety Authority (EFSA). It takes vector surveillance to the next level by combining entomological expertise with data-driven tools.
Specifically, VectorNet:
Maps the presence and activity of key vector species across Europe and neighboring regions
Maintains aninteractive map that shows up-to-date vector distribution, accessible to researchers, public health agencies and the public
Promotes cross-border cooperation by standardizing how vector data is collected and shared, helping countries respond quickly to new risks
This integrated surveillance system keeps Europe alert and prepared as environmental and ecological conditions shift.
What Are Europe’s Vector Preparedness Strategies?
With climate patterns shifting and global travel on the rise, European countries are ramping up their efforts to prevent and manage vector-borne disease outbreaks. Preparedness means building systems that anticipate and respond to threats early, both nationally and across borders.
Here’s how that work is unfolding:
Collaboration with the World Health Organization (WHO)
European countries partner with the World Health Organization to align their vector preparedness strategies with global standards. The WHO offers technical guidance, training and risk assessment tools that support vector control programs and outbreak response. This partnership ensures Europe’s efforts are part of a global push to reduce vector-borne diseases.
National Action Plans
Each EU member state develops its own vector preparedness plan tailored to local ecology, climate conditions and public health infrastructure. These plans typically include:
Routine vector surveillance and early detection systems
Emergency protocols for outbreak response
Public awareness and education efforts
Cross-Border Coordination
Mosquitoes certainly don’t need tiny passports to fly from one country to another, which is why cross-border preparedness is essential. Countries work closely with one another through EU-level frameworks like the Health Emergency Preparedness and Response Authority (HERA).
HERA helps by:
Coordinating joint purchases of medical supplies like vaccines and diagnostic tests
Sharing data on outbreaks and vector trends
Running simulations and drills to test emergency response systems
How Europeans Learn About and Prevent VBDs
VBD preparedness doesn’t end with labs, legislation and logistics. It trickles down into everyday life, and that’s where public awareness comes in. Educating people about how vectors spread and what symptoms to watch for is key to prevention. When people are informed, they’re more likely to protect themselves and less likely to contribute to local disease spread.
EU member states use both classic public health outreach and digital tools to engage people where they are. Effective efforts include:
Public education campaigns, like travel advisories and school programs
Community engagement, such as volunteer vector monitoring and neighborhood vector control programs
Digital tools, like mobile apps that alert users to breeding sites and social media campaigns that deliver facts and infographics about vector risks

At first glance, the pairing might seem impossible. But careers that appear unrelated can sometimes overlap, especially when science is involved. Here’s a…
If you’ve ever swatted away mosquitoes on a humid summer evening, you know the relief that winter brings when their buzzing fades. Now imagine sipping hot chocolate on a crisp holiday morning … only to find yourself swatting mosquitoes again.
Wait, what? That can’t be right. Mosquitoes are supposed to give us a break during the chilly winter months.
It might sound far-fetched, but it could become our reality. Climate change isn’t just about warmer temperatures. It’s transforming the way insects behave: altering their lifecycles, migration patterns and seasonal activity.
Climate change is causing big changes in insect behavior. Disease-carrying pests like mosquitoes and ticks are acting differently, and helpful pollinators like honey bees are changing how they gather food and reproduce. These shifts can affect public health, our food supply and the balance of entire ecosystems.
How Is Climate Change Transforming Insect Behavior?
Climate change is transforming insect behavior by altering their body temperature regulation and biological processes, which are highly influenced by environmental conditions. Insects are ectothermic, meaning the environment plays a big role in determining their body temperature and biological processes.
As global temperatures rise — the Earth is now about 2.5°F hotter than it was in the pre-industrial era — and rainfall and humidity levels fluctuate, insects are responding in ways that scientists are only beginning to truly grasp.
These climate-driven shifts can lead to the following changes:
Faster lifecycles Warmer temperatures speed up insect development, allowing some species to produce more generations annually. For vectors like mosquitoes, this means faster reproduction and more chances to spread disease.
Expanded habitats Insects once limited to tropical or temperate regions are moving into new areas as temperatures rise and ecosystems shift. This could introduce unfamiliar species — and new challenges — into communities not previously affected.
Longer active seasons Milder winters and earlier springs mean insects can become active earlier and stay active longer. Some species now survive winter more easily and emerge ahead of schedule, disrupting plant-pollinator timing and increasing human exposure to biting pests.
How Do Rising Temperatures Affect Disease-Carrying Insects?
Rising temperatures aren’t just increasing insect populations — they’re also changing how disease-carrying insects behave and where they thrive. Warmer conditions speed up reproductive cycles, allowing insects like mosquitoes to bite more frequently and spread diseases faster.
These insects are also expanding into new regions as areas that were once too cold become more hospitable. This means communities that have never faced threats like dengue, Zika, or West Nile virus may now be at risk. Combined with longer active seasons due to milder winters, these shifts are significantly increasing the window of time when humans and animals can be exposed to vector-borne diseases.
How Is Climate Change Threatening Honey Bee Health?
Climate change threatens honey bee health by disrupting their behavior, foraging patterns and colony stability. According to The Bee Conservancy, honey bees pollinate one in every three bites of the food we eat and 80% of the world’s flowering plants. Their importance to the ecosystem and food supply can’t be overstated.
Already facing a one-in-four risk of extinction, honey bees now face an even greater threat: climate change. Here’s how rising temperatures and shifting weather patterns are altering bee behavior, and why it matters:
Phenological mismatch
Honey bees rely on environmental cues like temperature to signal when it’s time to emerge from their hives. But as spring arrives earlier, bees are waking up before the plants they depend on have begun to bloom.
This disconnect, called phenological mismatch, can result in temporary food shortages for bees. Even a few days’ difference between emergence and flowering can disrupt feeding patterns, reduce energy reserves and diminish pollination success. Over time, this can impact not only bee health but also the reproductive success of many plants.
Hive Stress and Population Decline
Extreme heat can damage the queen’s sperm storage, lowering fertility and egg production. Meanwhile, milder winters may prevent bees from entering full dormancy, draining their energy and making hives weaker.
Worse yet, warm winters help pests like Varroa mites survive and spread. These invasive parasites feed on both adult bees and the queen’s developing brood, transmitting viruses and weakening entire colonies.
Ripple Effects on Agriculture
When bee populations decline, the consequences extend far beyond the hive. Reduced pollination threatens the yield and quality of dozens of pollinator-dependent crops, from almonds to blueberries. This could lead to:
Lower food availability
Higher prices
Long-term impacts on biodiversity
Make a Difference With an Online Degree in Entomology
Changes in insect behavior are more than a scientific curiosity; they’re an emerging public health concern. As temperatures rise, seasons shift and insect habitats expand, we face new and more serious challenges.
Essential pollinators like bees are under increasing stress, threatening food production and biodiversity. At the same time, climate-driven shifts in vector behavior could spread more vector-borne illnesses in new regions. Together, these disruptions carry extensive implications for global health, agriculture and ecological stability.

If you find yourself adding an extra layer of bug spray before your evening walks or instinctively swatting at every passing mosquito, your heightened vigilance is justified. Cases of vector-borne diseases have surged in recent years. There were over one million cases between 2001 and 2023 in the United States alone—and that number only includes reported cases.
The CDC estimates that only one in ten West Nile virus cases is reported, and the true number of Lyme disease cases could be ten times higher than those officially documented. This potential underreporting suggests an even larger and more concerning spread of vector-borne diseases within the United States, not to mention other countries around the world.
What Are Vector-Borne Diseases — and Why Are They Increasing?
Vector-borne diseases are infections transmitted to humans and other animals through insects, known as vectors, that carry pathogens. Vectors such as mosquitoes, ticks and fleas become infected when they feed on a host carrying a virus, bacteria or parasite. As they continue feeding on other animals or humans, they can transfer the pathogen, potentially causing illness in the newly infected host.
The question remains: Why are vector-borne disease rates increasing?
Several factors affect the number of recent cases.
Climate Change
When it comes to climate change and vector-borne diseases, rising temperatures and changing precipitation patterns are reshaping ecosystems to favor disease-carrying insect populations. For instance, the record-breaking heat of 2023, which was 2.12°F above the 20th-century average, is a perfect example of how rising global temperatures can boost the populations of disease-carrying insects. Insects like mosquitoes thrive in warm environments, and climate change is enabling them to expand their habitats, possibly even into regions that were once too cold for them to survive.
In addition to temperature shifts, climate change intensifies the total rainfall in certain areas. Frequent rain creates more standing water, an essential component for mosquito breeding. With more precipitation, mosquitoes are given the ideal conditions for increasing their numbers, therefore boosting the likelihood of outbreaks in these regions.
Globalization
The affordability and accessibility of modern transportation have transformed global travel. Planes, trains and automobiles have made it increasingly easy for people to explore new destinations and reconnect with distant family members. However, this ease of travel also inadvertently helps pathogens reach new regions.
Unknowing travelers can carry vector-borne diseases to places that may lack the public health infrastructure or immunity levels to effectively manage and contain outbreaks. When they arrive at their destination, a mosquito or other vector might bite them and transmit the pathogen to other humans, possibly triggering an unwanted outbreak in that region.
Air travel, specifically, offers a quick means for vectors hitchhiking in cargo and infected individuals to reach new areas. This ease of global movement makes it much easier to rapidly spread diseases like malaria and dengue.
Potential Solutions to Reduce Infection Rates
As awareness of increasing infection rates grows, developing effective solutions to this problem becomes increasingly crucial. Below, we explore some potential strategies.
Creating climate change improvement efforts
To lower temperatures and mitigate the effects of climate change, it’s essential to reduce greenhouse gas emissions. Although this is a significant undertaking, transitioning to renewable energy sources and enforcing regulations like carbon pricing could help slow climate change. On a smaller scale, communities affected by increased precipitation could lead initiatives focused on neighborhood cleanups to reduce standing water and promote the use of insect repellent.
Enhanced public health strategies
While some vector-borne diseases are resistant to drugs and lack vaccines, others do have available vaccines, such as the one for malaria. Providing at-risk communities with these vaccines and other resources, like insect repellents and mosquito nets, can help limit exposure and decrease infection rates.
Other public health initiatives to consider include:
Providing community education Many communities lack an understanding of the basics regarding vector-borne illnesses. Awareness campaigns via social media and local workshops could teach individuals about how these diseases are transmitted, preventative strategies and symptoms to watch for.
Surveilling vectors Professionals, such as entomologists or public health officials, can monitor vector species and track the presence of pathogens to help predict and respond to outbreaks more quickly. Surveillance data also helps communities prepare for high-risk seasons.
Be Part of the Solution: Become a Medical Entomology Professional
As the need for effective control of vector-borne diseases grows, so does the demand for medical entomologists to study vector behavior, disease transmission and control methods. With the right training, you can transform your passion into a rewarding, life-saving career.
