Yale Study Shows Disease Bearing Mosquitoes Adapt To Winters

The adaptability to higher latitudes of these mosquitoes, known to have transmitted dengue and Zika in Florida, “may be a harbinger of things to come,” said Yale’s Jeffrey Powell, professor of ecology and evolutionary biology and senior author of the study appearing December 18 in the American Journal of Tropical Medicine and Hygiene. No known cases of locally transmitted dengue, Zika, or chikungunya have been reported in Washington, but the mosquito species “has already shown it can transmit disease in modern urban settings,” Powell said. Yale’s Andrea Gloria-Soria is first author of the study. Reference: “Origin of a High-Latitude Population of Aedes aegypti in Washington, DC” by Richard G.
