摘　　要：本文综述寄生蜂畸形细胞特性及其功能研究的最新进展。一些进化高等的膜翅目内寄生蜂,在胚胎发育过程中,包裹在胚胎周围的浆膜会随着蜂卵的孵化,以游离的细胞团或单个细胞的形式释放到寄主昆虫的血淋巴中。这些源自浆膜被称作"畸形细胞(Teratocyte)"的特殊类群,在伴随蜂幼虫的生长发育过程中,自身也经历一系列结构和功能的改变。它们主要通过分泌蛋白质或酶类,改变寄主的物质代谢途径等方式为发育中的蜂幼虫提供营养和能量。对寄生蜂重要的调控因子-畸形细胞的特性及与蜂幼虫相互关系的揭示,可以阐明寄生蜂-寄主昆虫协同进化的内在机理,也可为开发害虫生物防治新策略提供新的思路和途径。The advances of research on the characterization of parasitoid teratocytes and their physiological functions were reviewed. In some advanced hymenopteran endoparasitoid species, upon egg hatching, the serosal membrane surrounding the embryo releases numerous teratocytes in the parasititized host haemolymph. Synchronous with the development of endoparasitoid larvae, teratocytes develop, and undergo drastic morphologic changes. These cells absorb host nutrients and secret proteins, enzymes, or redirect the host nutrition to meet for the need of developing parasitoid larvae. The teratocyte is essential for parasitoid larvae survival and successful development. If we could make clear of the functions of this type of special cell in regulating the host, it would be potentially useful in developing new biological control agents.
