摘要：

为了解决稻田害虫的生物防治及生态控制技术，以稻田捕食性天敌为研究材料，采用田间调查、采集标本、室内鉴定的方法，对稻田捕食性天敌进行了初步研究。研究结果表明：在通辽地区稻田生态系统中，有捕食性天敌20科59种，其中捕食性昆虫属于蜻蜓目、螳螂目、脉翅目、半翅目、鞘翅目5个目的10科32种，捕食性蜘蛛9科25种。优势种主要是黑肩绿盲蝽、青翅隐翅虫、龟纹瓢虫、草间小黑蛛、机敏漏斗蛛，占捕食性天敌总量的45.5%。

Abstract:

In order to solve biological control and ecological control techniques to paddy pests, predators as materials, we studied the predatory natural enemy of paddy using the field survey, collecting specimens and indoor identification method. The results showed that there were 59 predator species belonging to 20 families in paddy ecosystem of Tongliao Areas. Among of them, 32 species of insect belonging to 10 families, 5 orders, 25 species of spider belonging to 9 families and 2 species of frog belonging to Ranidae were identified. The five insect orders were Odonata, Mantodea, Neuroptera, Hemiptera and Coleoptera separately. The dominant species were Cyrtorrhinus lividipennis Reuter, Paederus fuscipes Curtis, Propylea japonica (Thunberg), Erigonidium graminicolum (Sundevall) and Agelena difficilis Fox. They accounted for 45.5% of the total of predatory natural enemy.
