Testing field-caught mosquitoes for insecticide resistance is a critical effort in the fight against malaria and other vector-borne diseases. Researchers in Thailand say a “forced oviposition” method has proven successful in inducing field-caught Anopheles mosquitoes to lay eggs and spawn lab populations big enough for insecticide-resistance testing.
Analysis of tick photos submitted to the TickSpotters program finds three tick species that transmit Lyme and other human diseases are present in hundreds of U.S. counties where previous surveillance had not yet documented them.
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.
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.
Biosecurity research at Kansas State University adds to the chorus of studies showing mosquitoes and other insects are not biological vectors of SARS-CoV-2, the coronavirus that causes COVID-19. Here's a look at how that research is conducted.
