Mosquito Sprays Can Reduce West Nile Virus Risk, Even If Population Numbers Don’t Drop
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.
Plant Pollen May Be Important Food Source for Some Mosquitoes in U.S.
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.
U.S. Policy Leaves Country Vulnerable to Arthropod-Borne Diseases
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.
West Nile Virus: Reflections on 20 Years in Pursuit of an Elusive Foe
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.
