Juvenile hormone agonist, fenoxycarb was exposed to the 3rd instar larvae of rice moth, Corcyra cephalonica (Staint) and their insecticidal activity was evaluated. The 3rd instar larvae were exposed to six concentrations of fenoxycarb i.e. 0.001, 0.005, 0.01, 0.05, 0.10 and 1.00 ppm. The results showed that the higher concentrations of this compound disrupt the metamorphosis of C. cephalonica. A significant difference in duration of growth, larval mortality, pupation, pupal mortality, adult emergence and their longevity in comparison to their control were observed. At its 1 ppm concentration, fenoxycarb caused 90.00 ± 1.71% larval mortality with a very poor pupation of 10.00 ± 1.71%. But the later get perished and hence failed to emerge. At comparatively higher concentrations i.e. 0.05, 0.10 and 1.00 ppm a dose–dependent supernumerary larvae were formed that after a variable duration of time get perished.
