The effects of dimethoate on predatory Coleoptera were investigated using topical toxicity bioassays. Six species were evaluated: Tachyporus hypnorum, Coccinella septempunctata, Demetrias atricapillus, Trechus quadristriatus, Bembidion obtusum, and Nebria brevicollis. The LD sub(50) values ranged 3....
