A new study shows the malaria-transmitting Anopheles stephensi has a strong preference for type B human blood. The finding has implications for identifying individuals at high risk of mosquito-borne disease, but those with other blood types shouldn't put away the insect repellent.
In search of a simple, cost-effective way to maintain laboratory mosquito colonies, biologists at a mosquito control district in Florida have turned to food-grade frozen animal blood found at specialty grocery stores. They share the success of their new method for other cash-strapped mosquito-management operations in the open-access Journal of Insect Science.
An entomologist studying the biology of mosquito blood-feeding finds that a mosquito with a severed ventral nerve cord can't sense when it is full, and it will keep on feeding well beyond what its body can hold. Video captured by the researcher illustrates the results.
