Abstract

This work evaluated, under controlled conditions, the predatory capacity and the intraguild predation of Ceraeochrysa valida and Chrysoperla externa, with Diaphorina citri as prey. Statistical analysis indicates an asymmetric intraguild predation in favor of Ch. externa when prey density is low. There were no statistical differences in the predation of D. citri between both chrysopids when preying upon D. citri individually or in combination. It is concluded that the intraguild predation in favor of Ch. externa over Ce. valida depends on the density of the prey, and that the population of D. citri can be decreased by effect of a single chrysopid species.
