Parasitization of Goniozus legneri (Hymenoptera: Bethylidae) at Increasing Parasite and Host, Amyelois transitella (Lepidoptera: Phycitidae), Densities

Abstract

Goniozus legneri Gordh oviposition behavior was significantly influenced by variations in host-parasite densities. Oviposition rates tended to increase with increases in host density. Sex ratios, although strongly female biased (>82%), were significantly influenced by host-parasite density within a range of about 10%.
