| Abstract |
In 1969 a sticky trap, designed to float over the water's surface and catch adult chironomids as they emerged, was tested at a pond, lake and stream in the Cincinnati, Ohio vicinity to determine its suitability as a surveillance tool, and to better define the chironomid fauna in the central region of the Ohio River Basin. The trap is described and illustrated. 55 chironomids representing 34 gen, including 14 new spp were collected. The ratio of male chromosomes to female chromosomes was 1:2. Labrundinia pilosella represented the most abundant male chromosomes collected at the pond and lake and Psilotanypus bellus occurred most consistently at all locations. The floating sticky trap tested is not recommended as a primary quantitative surveillance tool for most aquatic insects due to the apparent bias of the trap for small weak-flying insects, the capture of wind borne and terrestrial adults and technical problems inherent with the use of sticky material. It does embody features, which make it suitable as a supplementary collecting device for most Chironomidae. |
