Genes that make mosquitoes glow under UV light help scientists measure the spread of transgenic mosquitoes after they've been released to suppress wild populations of vector mosquito species. A recent study identifies a new promoter gene for turning on fluorescent protein production in Aedes aegypti mosquitoes.
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.
A look at the body of research on how and when day lengths trigger mosquitoes to enter winter diapause suggests more data on mosquito species' critical photoperiods and their relation to latitude and altitude could better align surveillance and management efforts with mosquitoes' seasonally active periods.
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.
