Abstract

Topical application of graded doses of 12 insecticides belonging to the organochlorine, organophosphorus and carbamate groups to 4th-instar larvae of multivoltine (Pure Mysore) and bivoltine (Kalimpong A) races of Bombyx mori showed sequential development of neurotoxic symptoms (excitation, head swaying, vomiting of gastric juices and a moribund state) followed by death. Organochlorine insecticides were generally rapid in their action compared to the organophosphorus and carbamate insecticides. Gamma-HCH [lindane] and endosulfan were the most toxic, and bromophos the least, among the insecticides tested. Similar toxicity was observed in the multivoltine and bivoltine races.
