Interpretive Summary:

Technical Abstract: An artificial diet developed for Serangium parcesetosum (Coleoptera: Coccinelidae) is suitable for development of adults from second instar larvae. Adults that developed on this diet produced eggs and survived for at least 120 days. Eggs from these adults were fertile, and the larvae that hatched from them were able to revert to feeding on natural prey (whitefly nymphs) and adventitious prey, including pink bollworm eggs and Sitotroga eggs. First instar S. parcesetosum were unable to feed through the parafilm membrane because their mouthparts are too small to penetrate even stretched film.
