The present investigation reveals the influence of methoprene, an IGR, on the ontogeny, growth duration and adult longevity of the rice moth Corcyra cephalonica. Twenty-five larvae of different instars (1 st , 2 nd , 3 rd and 4 th ) of C. cephalonica were exposed to the juvenile hormone analogue methoprene in order to evaluate its potential effect on larval mortality, pupation, pupal mortality, adult emergence, growth duration and adult longevity. These different instars larvae were treated with 2, 4, 8 and 12 ppm of methoprene in an artificial diet (coarsely ground jowar mixed with 5% yeast powder) where the control received acetone alone. The results reveal significant differences in all the parameters mentioned above as compared to the control.
