摘　　要：本文基于28S rDNA D2部分序列,用MP和ML方法对几种寄生夜蛾科的多胚跳小蜂Copidosomaspp.进行了系统发育研究,并对其形态和生物学关系进行了讨论。结果表明:寄生金翅夜蛾亚科(Plusiinae)的C.floridanum和寄生实夜蛾亚科(Heliothinae)的C.primulum关系较近,而以夜蛾亚科(Noctuinae)为寄主的C.truncatellum和C.agrotis关系更近。结果提示核基因28SD2区可能对研究多胚跳小蜂种间的系统发育关系很有帮助。Phylogenetic relationships amongst Copidosoma spp.,e.g.C.floridanum,C.primulum,C.truncatellum and C.agrotis(Hymenoptera:Encyrtidae)associated with noctuid hosts(Lepidoptera)are inferred from nucleotide sequences of the D2 region of 28S rDNA.Both maximum-parsimony and maximum-likelihood analysis showed that C.floridanum and C.primulum,associated with Plusiinae and Heliothinae hosts separately,descend from a theoretical common ancestor,while C.truncatellum and C.agrotis associated with Noctuinae are more clos...
