Mosquitoes Have Learned to Avoid Pesticides Used to Kill Them Says a UK Study

Image credit: Pixabay Mosquitoes are getting smarter these days. With the changing environment, they are adapting to new ways of survival. According to the scientists at Keele University in the U.K , they are learning new ways to avoid pesticides used to kill them. Scientists studied two species of mosquitoes Culex quinquefasciatus and Aedes aegypti . These two species are responsible for spreading diseases such as West Nile Fever, Zika, malaria , yellow and dengue fever. In recent years, pesticide resistance among mosquitoes has increased. However, the extent of this ability in different species of mosquitoes is still unknown. Scientists found that the female mosquitoes have learned to identify the smell of venomous pesticides after a single harmless exposure to pesticides. During the experiment, researchers exposed female mosquitoes to safe doses of common anti-mosquito pesticides. They observed that mosquitoes that were earlier exposed to these pesticides avoided passing through t
