落叶松卷叶蛾(Pt ycho lomoides aerifercenus Herrichschaffer)是落叶松人工林害虫,为探讨寄生蜂对其控制作用,我于1973—1981年,在黑龙江省山市、边林等五个地区,对卷叶蛾12种寄生蜂的发生、消长和寄生情况,做了初步观察,简介如下。二、发生与消长情况春季落叶松林内气温12—20℃时,上述寄生蜂(旋小蜂除外)相继羽化,最先出现的是幼虫期寄生蜂,发生的顺序是:黑青小蜂→姬小蜂→金小蜂→甲腹茧蜂→茧蜂。其
In order to discuss the control effect of parasitoid, Pt ycho lomoides aerifercenus Herrichschaffer is a pest of larch plantation. From 1973 to 1981, I studied 12 species of leaf roller moth in five areas of Shanlian and Bailin, Heilongjiang Province, The occurrence of parasitic wasps, growth and parasitism, made a preliminary observation, briefly as follows. Second, the occurrence and growth of the situation Spring larch forest temperature of 12-20 ℃, the parasitic wasps (spinus except) were the emergence of the emergence of the first larvae parasitic wasp occurred in the order: black bee → Ji Little bee → golden bee → beetle bee → bee bee. its
