AbstractThe behavior of larval stages of the green lace wing, Chrysopa carneaStephens, and of the ladybird beetle Hippodamia convergensG.-M. were studied in the laboratory. With increasing hunger level, only first instar H. convergenslarvae spent more time searching in the upper part of alfalfa stems, where both prey aphids, Acyrthosiphon pisum(Harris) and Acyrthosiphon kondoi(Shinji), are found. All larval instars tested except first instar C. carneavisited more stems per unit time with increasing hunger level. The weight gain, the developmental time, and the mortality of all larvae were adversely influenced at low food levels, but differently for each predator size and species. C. carnealarvae had higher rates of fat body utilization and weight gain than coccinellid larvae.
