Evaluation of a novel emergence trap to study Culex mosquitoes in urban catch basins.

Stormwater catch basins in urban areas provide important larval habitat for Culex mosquitoes. In this study we quantified adult Culex emergence using a newly designed emergence trap deployed in catch basins in suburban Chicago, IL. Traps were deployed from late June to mid-October, 2009-10, in 19 catch basins for a total of 461 trap-days.
