摘　　要：柳杉毛虫是一种严重为害柳杉的食叶害虫,探明柳杉毛虫的寄生蝇种类,将为该虫优势天敌的筛选提供更多的选择。本研究从野外采集柳杉毛虫幼虫并带回室内饲养,出蛆化蛹,羽化获得不同种类的寄生蝇。对获得的寄生蝇进行分类、鉴定,并描述其系统分类地位、形态特征、地理分布及寄主。调查发现,柳杉毛虫的寄生蝇由多到少依次为蚕饰腹寄蝇Blepharipa zebina(Walker),瘦钩鬃麻蝇Sarcophaga(Sarcorohdendorfia)gracilior(Chen),黑角狭颊寄蝇Carcelia(s.str.)nigrantennata Chao et Liang,松毛虫狭颊寄蝇C.(s.str.)matsukarehae(Shima),星毛虫狭颊寄蝇C.(s.str.)illiberisi Chao et Liang,拟庸赘寄蝇Drino(Palexorista)inconspicuoides(Baranov),羚足鬃麻蝇S.(Sarcorohdendorfia)antilope Böttcher,共7种,其中蚕饰腹寄蝇、瘦钩鬃麻蝇、黑角狭颊寄蝇分布较广,种群数量较多,寄生率较高,分别为7.44%、7.37%、5.48%,被认为是优势种;且拟庸赘寄蝇为福建新分布记录;柳杉毛虫是黑角狭颊寄蝇、星毛虫狭颊寄蝇、拟庸赘寄蝇的新寄主;还发现2种重寄生蜂寄生于寄生蝇。记述柳杉毛虫的7种寄生蝇形态特征,有助于今后识别其天敌昆虫,研究害虫与天敌的种间关系,评价寄生蝇种群对维护柳杉林分生态系统稳定和防控柳杉毛虫的潜能,具有重要意义。Dendrolimus houi(Lajonquiere)is a caterpillar species which seriously infested forests of Cryptomeria fortune.Investigation on the parasitic fly species of D.houi will provide alternatives for the selection of their natural enemies.In this paper,some caterpillars of D.houi were collected from the wild populations and reared in the laboratory until adults of parasitic flies emerged,then taxonomic category,adult morphology,geographic distribution and hosts of parasitic flies were identified and described.The results showed that there were seven species of parasitic flies attacking D.houi,including Blepharipa zebina(Walker),Sarcophaga(Sarcorohdendorfia)gracilior(Chen),Carcelia(s.str.)nigrantennata Chao et Liang,C.(s.str.)matsukarehae(Shima),C.(s.str.)illiberisi Chao et Liang,Drino(Palexorista)inconspicuoides(Baranov),S.(Sarcorohdendorfia)antilope B ttcher.B.zebina,S.gracilior and C.nigrantennata were defined as dominant species due to their wider distribution,higher population and parasitism rate in the field.D.inconspicuoides was a new record in Fujian Province,while C.illiberisi,C.nigrantennata and D.inconspicuoides were firstly reported and described as parasitic flies attacking caterpillars of D.houi.Meanwhile,two other hyperparasitic species of D.houi were also found.Brief description of morphology of seven parasitic flies will be very helpful to identify the natural enemies of D.houi,characterize the interaction relationship between D.houi and its natural enemies,and evaluate the population stability and potential suppression effect of parasitic flies in the forests.
