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.
Medical entomologists are 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:
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.
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:
The University of Florida, for example, uses drones to find mosquito breeding sites in Florida wetlands for targeted control.
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:
Need a real-world example? This new smart trap automatically counts mosquitoes in the field and transmits live updates.
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.
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 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!
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.
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.
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:
Does the thought of tackling vector-borne diseases with the newest technology excite you?
The University of Florida is a leader in entomology research and home to the nation’s top-ranked entomology programs, with specializations in:

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…
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…
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…
