Combined action of neem (Azadiracta indica) and eucalyptus (Eucalyptus sp.) oil volatiles causes a sharp reduction in percent egg hatchability in rice moth, Corcyra cephalonica (Stainton) (Lepidoptera: pyralidae) when freshly laid eggs were exposed to these volatiles for 24 hours. A marked decline in egg output and egg hatchability in reproductive pairs, was observed whose larvae were allowed to develop in a programmed manner in an environment, laden with combined action of selected volumes of neem and eucalyptus oil or when both the sexes of these pyralids, were confined for the prescribed limited period, in such odorous environment. A significant reduction in glycogen, lipid and protein level and an increase in free amino acids was noticed in testes and ovaries of these pyralids, when breeding pairs were exposed to the selected volatiles for a period of six hours only.
