Chrysopid Predators and their Role in Biological Control

M.L. Pappas, G.D. Broufas and D.S. Koveos    

Abstract: The family Chrysopidae includes many species that could be considered important biological control agents. Chrysopid larvae and the adults of certain species are polyphagous predators and feed on several pests of economic importance. The use of chrysopids in biological control has been enabled by the development of efficient mass-rearing facilities for species bearing certain characteristics, such as Chrysoperla species. From the different approaches used in implementing biological control, augmentation release is the most commonly applied method in the case of chrysopids. To date, only some Chrysoperla sp. are commercially available for use in biological control. Food supplements, attractants and hibernation boxes are also available for enhancing conservation of chrysopids. Difficulties in the systematics of chrysopids have made the release of Chrysoperla sp. more problematic. The evaluation of the efficacy of chrysopid species that share common characteristics with Chrysoperla sp. as potential biological control agents, as well as further studying the performance of Chrysoperla species under field conditions could enhance their role in Integrated Pest management (IPM).
