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 mosquito populations are monitored using New Jersey Light Traps set around the state.
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. Click on "County" on the left side of the page to see individual county data. Click "Year" to see historical data comparing yearly mosquito population trends.
Summary for the week of June 22, 2012: Trap results from around the state show that mosquitoes are relatively inactive right now. This is one of our slowest years in recent memory. As you can see from the data on the Iowa Mosquito Surveillance website mosquitoes are even less active now than they were last year at this time, and this is stating something because last year was memorably low in mosquito abundance (aside from the flooded western Iowa situation).
