Evaluation of Insecticides, Clothing Repellents, and other Approaches to the Control of Sand Flies, Culicoides spp.

摘要

Population dynamics and control studies on Culicoides biting midges were continued at Parris Island, South Carolina, and Yankeetown, Florida. Studies on immature populations were conducted at both sites. At Parris Island the most productive breeding areas were under large logs in the marsh proper or areas shaded by oak trees. At Yankeetown during a 10 wk study, Dishtichlis vegetated areas were most productive. No large difference was detected between the larval densities from the gridded marsh area (also studied in 1981) and the surrounding marsh areas. In chemical control studies, evaluations of permethrin and NRDC-161 as window screen treatments were continued. Aerial ULV tests using 1.0 oz Dibrom 14/acre resulted in a significant reduction of natural populations of adult Culicoides at Parris Island.
