Mosquito ecology and WNV transmission


Long-term surveillance provides insights into WNV transmission dynamics in Iowa

Since 2002, the Medical Entomology Lab at Iowa State has been monitoring mosquito populations and performing virus testing (in cooperation with the State Hygienic Lab) to better understand WNV transmission. Combining data from previous efforts under the stewardship of Wayne Rowley and Lyric Bartholomay, we have now assembled 15 years of mosquito abundance and virus infection data to being to tease apart the transmission dynamics of WNV for the state of Iowa. From these results, clear patterns of infection emerge in western Iowa that correspond with Culex tarsalis abundance. 

Surveillance provides important insights into mosquito abundance and species distribution

With nearly 50 years of New Jersey light trap data (, as well as comparable data from several other trap types, we have begun to define mosquito abundance and species distributions across the state. This includes the introduction of invasive species into the state and monitoring of their spread. With millions of mosquito records, we are always open for collaborative projects looking to take advantage of our unique data set.
