Seasonal abundance and distribution of mosquitoes at a rural waste tire site in Illinois.

The species composition, abundance, and distribution of mosquito larvae in tires were determined on 3 dates at a relatively large rural tire dump (about 300,000 tires) in southeastern IL (Jasper County). Several observations at this site differed from those in previous reports about mosquitoes in tireyards, including 1) a relatively high percentage of tires positive for Aedes triseriatus larvae in an open-field area, 2) a greater abundance of Culex pipiens than Cx. restuans in late-season collections, 3) a seasonal change in the distribution of Aedes atropalpus larvae in tires from open field and edge of woods areas, and 4) the presence of Ae. albopictus as a major late-season species. Ae. albopictus adults were captured in sod-baited gravid traps along the edge of a wooded riparian area 200 m from the tire pile.
