[目的]对营口市区内美国白蛾主要寄生性天敌昆虫及寄生率进行研究,为该地区美国白蛾生物防治提供理论依据。[方法]采用野外大量采集和室内培养,利用主要寄生性天敌昆虫,进行试验。[结果]营口地区美国白蛾主要寄生性天敌有4种,分别为舞毒蛾黑瘤姬蜂(Coccygomimus disparis)、康刺腹寄蝇(Compsilura concinnata)、白蛾周氏啮小蜂(Chouioia cunea)和古毒蛾追寄蝇(Exorista larvarum),平均寄生率分别为2.18%、2.50%、3.90%和0.94%。[结论]白蛾周氏啮小蜂可能是生物防治营口市区美国白蛾的最佳优势种天敌。
Study on Parasitoid of Fall Webworm Pupa Overwinteringed in Yingkou Area
Objectove The paper mainly introduced Hyphantria cunea Drury with parasite insect category and parasite rate for biological control in Yingkou. [Method]To make clear of parasite insect category with the method of indoor colture. [Result]The main parasite host in Yingkou contains 4 species which were Coccygomimus disparis、Compsilura concinnata、Chouioia cunea、Exorista larvarum. The averge parasite rates were 2.18%, 2.50%, 3.90%and 0.94%. [Conclusion] Chouioia cunea could be best advantage of biological control of Yingkou city fall webworm predators.
