半翅目捕食性天敌昆虫评价研究

Study on Evaluation of Hemiptera Predatory Insects

半翅目捕食性天敌昆虫是自然界天敌资源的重要成员,在生态调控防治虫害中发挥着重要的作用,也是农业生产中可以利用的重要天敌资源。分析了半翅目捕食性天敌昆虫评价研究的现状,提出了半翅目捕食性天敌优势种评价的天敌控制当量分析方法和对目标害虫自然控制作用评价的天敌控制率分析方法。

Hemiptera predatory insects are important members of natural enemies and play a pivotal role in pest control in ago-ecological reg- ulation, which we can use in agricultural production to control pests. This paper analyzed the present research situation of the evaluation of He- miptera predatory insects, and proposed the analysis method of control equivalent for the dominant species evaluation and the analysis method of control rate of natural enemies for the natural control effect evaluation of Hemiptera predatory insects.
