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Copidosoma spp.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 C. agrotis关系更近。结果提示核基因28S D2区可能对研究多胚跳小蜂种间的系统发育关系很有帮助。

Abstract: Phylogenetic relationships amongst Copidosoma species, 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 show 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 closer to each other. The D2 region of 28S ribosomal RNA appears potentially useful for understanding phylogenetic relationships in this genus.
