Abstract:
Adults of the cowpea curculio, Chalcodermus aeneus Boheman, obtained from infested peas in Attapulgus (SW), Midville (Central) and Tifton (So. Central), GA; were treated topically in the laboratory, with es-fenvalerate, cyfluthrin, cypermethrin and permethrin in 1988 to establish base-line data for the documentation of potential insecticidal resistance. A preliminary test was conducted in 1987, using permethrin, es-fenvalerate, cypermethrin, cyfluthrin and cyhalothrin on insects from Tifton. The log dose probit analysis indicated that in 1987 cyhalothrin was the most toxic of the materials tested. The 1988 test showed that es-fenvalerate was less toxic than the others and was also less toxic in Tifton, where pyrethroid insecticides have been used more extensively, than in Midville and Attapulgus.
