摘　　要：多分DNA病毒(polydnavirus,PDV)是一类共生于膜翅目姬蜂科、茧蜂科和蚜茧蜂科寄生蜂体内的昆虫病毒。在寄生过程中,伴随着蜂卵的产出,寄生蜂将PDV注入寄主体内,通过病毒基因的表达,破坏寄主的免疫,以保障后代的存活。本文首次在烟蚜茧蜂和蚜虫模式体系内发现多分DNA病毒,初步明确其形态特征和生理效应。Polydnaviruses(PDVs) have a symbiotic association with hymenopteian parasitoid wasps in the fami-ly of Braconidae, Ichneumonidae and Aphidiidae. They are delivered into host hemolymph accompanying with theparasitoid egg laid during oviposition to serve to disrupt host immune system to ensure the survival of the wasps' progeny. Recent progress on braconid PDV characterization and gene families including PTP and EP 1-like relatedto immune suppression was reviewed. The morphological characteristics and physiological effect of polydnaviruswere firstly discovered in Aphidius gifuensis and aphids mode system.
