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.
A recent study found that female Aedes albopictus mosquitoes are larger in neighborhoods with more abandoned buildings—and larger mosquitoes are more likely to survive and breed.
When their ranges overlap, two invasive mosquito species mate but produce no offspring, in an event known as satyrization. They can evolve quickly to learn to avoid each other, but that choosiness may cost the mosquitoes in other ways.
A survey of mosquitoes in Pennsylvania discovered 12 mosquitoes parasitized by larval mites. Water mites can reduce the survival and reproductive success of mosquitoes, and entomologists are investigating such parasitism to evaluate its potential as a method for biological control efforts.
