In a container of water crowded with mosquito larvae, killing only some of them can sometimes result in more adult mosquitoes emerging than would have otherwise. New research on three container-breeding mosquito species details the complex dynamics between changes in larval density and mosquito survival and offers insight into the optimal timing for mosquito-control treatments.
Abandoned car tires are known for providing attractive egg-laying sites for mosquitoes, but new research shows that tires—especially when covered in snow—also insulate mosquito eggs from harsh winter temperatures.
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.
Research on the rate at which mosquitoes land on people in field tests and lab tests finds that common arm-in-cage test results differ significantly from those found in large-room or field tests. The findings point the way toward making tests of mosquito repellents more aligned with real-world conditions.
