Gonadotrophic effects of RH-5849, a non-steroidal ecdysone agonist on the rice moth Corcyra cephalonica St. (Lepidoptera: Galleriinae)

In several areas throughout the world, eggs of fictitious host insect, Corcyra cephalonica, are used to produce multiple natural enemies, such as Trichogramma species, which widely utilized for biological control lepidopterous pests on diverse crops in more than 30 nations. The purpose this study was determine efficacy RH-5849, a non-steroidal ecdysone mimic, gonadotrophic parameters rice moth, cephalonica. separated II instar larva received compound topically abdomen dorsum by means Hamilton micro syringe acetone. Five replicates (50 insect/replicate) were per each dosage. Similar insects without any treatment. mean number laid female moth worked out basis total ten females. dose-dependent way, sterility percentage enhanced while hatching decreased. indices shown be dose-dependent, according current data. It should not forgotten that percentages reversed effectuation tendency (egg viability).
