It's not enough to know mosquito abundance in a given area. Rather, the rate at which mosquitoes and humans actually come into contact is critical, a group of researchers say, to better understanding and modeling mosquito-borne disease transmission.
Researchers in Florida have pinpointed the local overwintering habitats of mosquitoes that host eastern equine encephalitis virus. They hope targeted control efforts can cull those mosquitoes before they transmit the virus to birds that carry it north to other parts of the country.
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.
