松毛虫平腹小蜂Anastatus sp.是我省落叶松毛虫Dendrolimus superans Butler卵期主要优势天敌蜂种之一;历来调查表明,控制松毛虫的发生、发展,往往起着主宰作用。它是目前我省利用柞蚕卵人工繁殖,防治松毛虫的蜂种之一。本试验旨在了解该蜂在林中自然的活动规律,以及提供有关单位在林中诱寄蜂种的参考。一、挂卵卡诱蜂林概况及其虫情 1.试验点设在长春市净月潭林场。挂卵卡诱蜂试验分别在阔叶林和针叶林内进行。针叶林地是一平山,近似圆形,面积约有5公顷,树种以黑松为主,其中约有1亩地的落叶松
Anastatus sp. Is one of the most important natural enemies of Dendrolimus superans Butler in our province. Historically, it has been shown that controlling the occurrence and development of pine caterpillars often play a dominant role. It is currently one of the bee species that use artificial breeding of tussah eggs in our province to control pine caterpillars. The purpose of this experiment is to understand the natural behavior of the bee in the forest and to provide a reference for the unit to lure bees in the forest. First, the concept of beetle lure ova and its pest situation 1. The test point is located in Changchun City Jingyuetan forest farm. The oviposition experiment was conducted in broadleaf forest and coniferous forest respectively. Coniferous forest is a flat mountain, approximately circular, an area of about 5 hectares, mainly black pine trees, of which about 1 acre of larch
