New Study Improves Sterile Insect Technique for Mosquitoes

Researchers in Florida find that male Aedes aegypti mosquitoes live longer when irradiated as adults rather than pupae, an important advance in protocols for deploying the sterile insect technique to manage wild populations of disease-transmitting mosquitoes.

Mosquito Populations Linked Across Further Distances Than the Viruses They Carry

In an analysis of mosquito sampling across 20 years in Connecticut, mosquito populations were often correlated at sites 10 kilometers apart and sometimes as far as 40 kilometers apart. But the same data showed the presence of mosquito-borne viruses rarely correlated across distances more than 5 kilometers, complicating potential approaches to managing mosquitoes and the risk of vector-borne disease.

Another Non-Native Mosquito Species Adds to Growing List in Florida

Mosquito researchers in Florida report the presence in the state of Culex lactator, a species previously known from Central and South America. The arrival adds to the growing list of non-native mosquito species finding their way into Florida—a worrying trend for public-health entomologists.
