Abstract

Because of their importance and abundance as predators of pest insects in agroecosystems around the world, eight species of lacewings from four genera (Apertochrysa, Chrysopa, Chrysoperla, and Dichochrysa) were investigated to evaluate their performance when reared on eggs of Ephestia kuehniella Zeller, a factitious prey commonly used in mass rearing systems. In particular, a comparative assessment of trash-carrying versus naked species (ones not carrying trash on their backs) was performed. We measured the developmental times and survival rates of the eight green lacewings and compared these characteristics between trash-carrying and naked lacewing species. Survival during immature development was higher (7787%) for the two naked species (Chrysopa pallens (Rambur) and Chrysoperla suzukii (Okamoto)) than for the trash-carrying species D. alcestes (33%). Immature and larval developmental times were significantly longer among the trash-carrying species than the naked species. The rapid development of naked green lacewings may be a strategy to decrease predation risk by aphid guarding ants and intra-guild predators.
