In spite of overlapping of ranges, no male made passes at a female of the wrong species. The Army's conclusion: a female mosquito must have other attractions than...
Except for the shrill whine of their wings, most varieties make no sound audible to man. But the Cornell researchers caged four of the peskiest species-Anopheles quadrimaculatus (malaria), Aedes aegypti (yellow fever), Aedes albopictus (dengue) and Culex pipiens (New Jersey) -and confronted them with a microphone and high-powered amplifier.

Females bellow; male voices are thin and high-pitched...
