In nature, inter- and intraspecific competitive interactions can occur between two or more female parasitoids foraging for hosts (=extrinsic competition) and multiple larvae competing for the host resources within the same individual host (=intrinsic competition). Knowledge and understanding of these interactions are important in biological control programs for selection of effective bio-control agents and management strategy to avoid conflict amongst exotic and native natural enemies.We evaluated the foraging strategies and intrinsic competitive interactions amongst three endoparasitoids, the solitary Meteorus pulchricornis (Wesmael), and the two gregarious Cotesia kariyai (Watanabe) and Cotesia ruficrus (Haliday) in their common host, Mythimna separata (Lepidoptera: Noctuidae). Furthermore, defense mechanisms employed by competing parasitoids to eliminate their competitors were also investigated during multi parasitism in focusing physiological stress of PDV or VLP and teratocytes.

在自然界中，种间和种内的竞争相互作用可以发生在两个或两个以上的雌性寄生蜂觅食的主机（=外在竞争）和多个幼虫竞争的主机资源在同一个主机（=内在竞争）。本文研究了三种内寄生蜂--单栖美角流星蜂Meteorus pulchricornis（Wesmael），单栖美角流星蜂Meteorus pulchricornis（Wesmael），以及在粘虫Mythimna separata（鳞翅目：夜蛾科）中的两种群居性卡赖谷绒茧蜂Cotesia kariyai（Watanabe）和红绒茧蜂Cotesia ruficrus（Haliday）。此外，还研究了竞争性寄生蜂消除竞争对手的防御机制，在多寄生集中在生理应激的PDV或VLP和畸形细胞。
