How Far Mosquitoes Travel
Getting a clearer picture of how far mosquitoes travel is a key part of vector control. Some species can travel hundreds of kilometers in a single night. They can also fly at different altitudes. Some breeds prefer to breed in tall trees, while others fly above sea level.
According to the National Institute of Allergy and Infectious Diseases (NIAID), it is possible to get a good estimate of how far a mosquito goes by performing a mark-release-recapture study. These studies use sticky traps and aspirators to mark and recapture the flying pests. Researchers then release the marked specimens back into the population. They also use meteorological modelling tools to determine the distance the mosquitoes traveled.
While a mark-release-recapture experiment is not necessarily the best way to learn how far mosquitoes travel, it is a good place to start. In fact, this type of research has the potential to change the way we understand how mosquitoes and other insects affect human health.
The researchers used a technique called source reduction, which removes breeding sites to focus on the most important factor, how far a mosquito goes. The result was a robust estimation of how far a mosquito goes. This was a particularly useful measure because the geographic distribution of the yellow fever mosquito is expected to expand with climate change.
The researchers tested how far a male mosquito would travel in the process of crossing a road. The average male will only travel about a hundred metres.
