Abstract

Evaluations were made of an encapsulated diet developed for rearing the green lacewing, Chrysopa carnea Stephens. Sizes of the capsules were similar to those of eggs of tobacco budworm, Heliothis virescens (F.), but considerably larger than those of eggs of Angoumois grain moth, Sitotroga cerealella (Olivier). Capsules were more resistant to dehydration than budworm eggs, but less resistant than grain moth eggs. Few 1st-instar larvae of C. carnea penetrated capsules; however, 2nd- and 3rd- instar larvae had little difficulty. All stages were effective in penetrating the shells of insect eggs. Some stages of Geocoris punctipes (Say), Reduviolus sp., Orius insidiosus (Say), Zelus renardii Kolenati, Coleomegilla maculata DeGeer, Hippodamia convergens Guérin-Méneville, and Collops sp. also fed on encapsulated diet.
