落叶松毛虫黑卵蜂Telenomus tetratomus Thomson是—种寄生于落叶松毛虫Dendrolimus superans(Butler)和赤松毛虫Dendrolimus spectabilis(Butler)卵的主要寄生蜂。近年来,在章古台沙地松林里有松毛虫发生但不成灾的非化防地段,自然寄生率显著上升,平均达50％以上,甚至可高达100％。与人工释放的松毛虫赤眼蜂Trichogramma dendrolimi Matsumura 相配 Telenomus tetratomus Thomson is a major parasitic wasp that parasites on the eggs of Dendrolimus superans (Butler) and Dendrolimus spectabilis (Butler). In recent years, in the pine forest in Zhanggu, there are non-chemical-resistant sections in which pine caterpillars occur but are not disastrous. The natural parasitic rate has risen significantly, averaging over 50% and even up to 100%. Matched with Trichogramma dendrolimi Matsumura, a Tricholoma gonorrhoeae, released by humans
