Abstract

Application of piperonyl butoxide, used to study the importance of mixed function oxidase (MFO) in metabolizing insecticides, suggested that MFOs were important in metabolizing pyrethroid and organophosphate insecticides in both the larvae and the adults of Helicoverpa armigera. Their effect was found to be constant over the pest generations. One ug of cypermethrin per 30–40 mg larva was found to be a good and effective diagnostic dose for the larval populations collected from Cicer arientinutn L. grown in Jhansi district.
