In a study of mosquitoes in and around the Nashville Zoo, northern cardinals were found to be the most common source of the mosquitoes’ blood meals, despite more than 300 species of animals on exhibit. None the less, the study suggests zoos are a valuable resource for monitoring mosquito species diversity, biology, and pathogen presence.
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.
Following the discovery that mosquitoes can ride high-altitude winds to travel long distances, further research is adding to both the scope and variety of species engaged in such migrations—factors sure to complicate efforts to curb transmission of malaria and other mosquito-borne diseases in Africa.
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.
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.
