摘　　要：为了明确广西南宁市稻纵卷叶螟寄生蜂种类,给合理保护、利用天敌提供理论参考,采用田间系统调查和室内饲养观察法研究了2011年广西南宁市稻纵卷叶螟寄生蜂的种类和发生数量。结果表明:南宁市稻纵卷叶螟寄生蜂种类有18种,分属于姬蜂总科Ichneamonoidea、小蜂总科Chalcidoidea。姬蜂总科中包含姬蜂科Ichneumonidae和茧蜂科Braconidae寄生蜂11种。小蜂总科Chalcidoidea中包含小蜂科Chalcididae、寡节小姬蜂科(姬小蜂科)Eulophidae、扁股小蜂科Elasmidae和赤眼蜂科Trichogrammatidae寄生蜂7种。其中稻纵卷叶螟姬小蜂Stenomesius maculatus Liao、纵卷叶螟绒茧蜂Apanteles cypris Nixon是幼虫期优势寄生蜂。在自然控制条件下,以稻纵卷叶螟姬小蜂的分布最广、种群数量最多,尤其是上半年,其发生数量占寄生蜂总数的89.7%;在施药与不施药两种管理模式下,施药区该蜂发生量占寄生蜂总数的69.1%,不施药区占78.5%。本文列出了寄生蜂分属、种检索表,可为田间种类识别鉴定提供参考。In order to definite the species of Cnaphalocrocis medinalis Guenee＇s parasitoids in Nanning, Guangxi Province and offer reference to protecting parasitoids, field survey of the species of C. medinalis＇s parasitoids were carried out in 2011 using field and Indoor examination. The results showed that there were 18 species parasitizing Cnaphalocrocis medinalis Guenee, which belonged to lehneamonoidea and Chalcidoidea. 11 species belongs to Ichneamonoidea which including Ichneumonidae and Braconidae. 7 species belongs to Chalcidoidea which including Chalcididae, Eulophidae, Elasmidae and Trichogrammatidae. In these parasitoids, Stenomesius maculatus Liao and Apanteles cypris Nixon were the main species on controlling Cnaphalocrocis medinalis Guenee. The population of Stenomesius maculatus Liao was larger than Apanteles cypris Nixon. Especially in the first half of 2011 , Stenomesius maculatus Liao shared in the total parasitoids as high as 89.7% in non - insecticide applied fields. All species of parasitiods in the paper was listed in an identification key, which can provide the reference for fiehl＇s species identification.
