Residual toxicity of different pesticides against seed beetles, Caryedon serratus (Bruchidae, Coleoptera) attacking stored groundnut at Bhubaneswar.

摘要

The residual toxicity of BPMC [fenobucarb], carbosulfan (each at 20, 40, 60, 80 ppm) and fipronil (10, 20, 30 and 40 ppm) against seed beetle Caryedon serratus infesting stored groundnut was studied at Bhubaneswar. The study indicated that the residual toxicity in the order of fipronil > carbosulfan > BPMC. Fipronil successfully checked the growth and multiplication of the beetle after 1 year of treatment. Third dose of each insecticide (60 ppm for BPMC and carbosulfan and 30 ppm for fipronil) wasfound to be superior than lower two doses and as effective as the higher dose.
