In a study of mosquitoes in and around the Nashville Zoo, northern cardinals were found to be the most common source of the mosquitoes’ blood meals, despite more than 300 species of animals on exhibit. None the less, the study suggests zoos are a valuable resource for monitoring mosquito species diversity, biology, and pathogen presence.
In a new study on truck-mounted mosquito-control sprays, the proportion of local mosquito populations that could potentially carry West Nile virus decreased after treatments, even though overall numbers of mosquitoes weren't affected—an "invisible" but positive sign about the utility of such mosquito management efforts.
Larvae of the southern house mosquito (Culex quinquefasciatus) fared well in a new study when fed a diet of corn or pine pollen. The findings suggest corn pollen could help the species— key vector of West Nile virus in the U.S.—thrive in habitats near agricultural areas.
A new study highlights problems with current government policy for managing vector-borne disease and the insects and arthropods that carry them and offers several recommendations for improvement.
The body of knowledge built since the arrival of West Nile virus in the Americas in 1999 is now powering efforts to minimize its impact and prepare for the invasion of other mosquito-borne diseases. A new special collection in the Journal of Medical Entomology takes stock of lessons learned and progress made over the past 20 years of West Nile virus research, surveillance, and control.
