摘　　要：为明确辽河三角洲稻区优势天敌情况,2011—2013年,于辽河三角洲稻区调查了水稻节肢类捕食性天敌及寄生性天敌昆虫的种类、数量,并分析其丰富程度。结果表明,辽河三角洲稻区的节肢类捕食性天敌优势种有3种,分别为横纹金蛛[Argiope bruennichi(Scopoli)]、粽管巢蛛(Clubiona japonicola Boes.et Str.)、草间钻头蛛[Hylyphantes graminicola(Sundevall)],全部为蜘蛛类;寄生性天敌昆虫优势种也有3种,分别为稻螟赤眼蜂[Trichogramma japonicun(Ashmead)]、松毛虫赤眼蜂[T.dendrolimi(Matsumura)]、螟黄赤眼蜂(T.chilonis Ishii),全部为卵期寄生蜂。To clear dominant natural enemy species in Liaohe River Delta, we investigated the species and quantities of natural enemies about arthropod predators and the parasitoids in Liaohe River Delta from 2011 to 2013. The results showed that there are six dominant species of natural enemies. For arthropod predators, they are Argiope bruennichi （Scopoli）, Clubiona japonicola Boes. et Str. and Hylyphantes grarninicola （Sundevall）, respectively. For parasitoids, they are Trichogramma japonicun （Ashmead）, T. dendrolimi （Matsumura） and T. chilonis Ishii, respectively, which are all parasitic during their host egg stage.
