Mosquito Numbers Continue to Decline

 Below is the summary of mosquito activity in Iowa from the ISU Medical Entomology Laboratory. Mosquito surveillance in Iowa has been ongoing since 1969. During the summer months, the Iowa State University Medical Entomology Laboratory, in cooperation with the Iowa Department of Public Health and the University of Iowa Hygienic Lab, monitors mosquito populations and mosquito-borne diseases in Iowa.


The Iowa mosquito collection data for the year are available online at the Iowa Mosquito Surveillance website. The statewide average mosquito counts by week (including a comparison to last year's mosquito activity) are shown.


Summary for the week of July 22, 2013


Iowa mosquito numbers have been dropping around the state and this week's trap collections continue the trend. We expect to report further decline next week due largely to water impoundments drying up all over Iowa.


Our first West Nile virus-positive mosquito pool was detected in Ames. It is that time of year, so be careful!
