Abstract

The impact of two chitin synthesis inhibitors, chlorfluazuron and triflumuron against the black cutworm, Agrotis ipsilon (Hufn.) was studied. Feeding technique was adopted. Different effects of these two chitin synthesis inhibitors on the 4th instar larvae were investigated. Effect on biological aspects, larval duration, larval weight, percentage of pupation, pupal duration, pupal weight, percentage of adult emergence, adult longivity, total oviposition period, number of eggs per female, egg hatchability and sterility percentage were studied. Effect of both compounds on total proteins and glycogen levels was also investigated.
