摘 要:作者于1986~1989年对河北省小麦吸浆虫的发生规律及综合防治技术进行了研究,查明了该省发生的吸浆虫是小麦红吸浆虫,一年发生一代,虫茧在土中越夏、越冬,长达10个多月.活动幼虫有随土温变化而垂直移动的习性,且与小麦生育期相一致.作者提出了“以种植抗虫品种为主,药剂主攻蛹期、成虫期扫残的化学防治为辅”的综合防治技术.三年来.经河北大面积应用,有效地控制了红吸浆虫为害,取得了显著效益.Investigations on the occurrence regularity of Sitodiplosis mosellana Gehin were made in Hebei province in 1986-1989. Now it becomes clear that one generation of this kind of insects emerges every year, and its cocoon lies in soil for over ten months to pass through the winter and summer. Its active larvae have a habit to move up and down with the changes of soil temperature, and the movement is concurrent with the development stages of wheat plant. In this paper a technique for integrated control of this kind of insects was developed.The technique,in short,is 'to rely mainly on the growth of the resistant varieties of wheat while making chemical control subsidiary' . The chemical control is carried out in the pupal stage to kill the insects as many as possible, and in the adult stage towipe out the remnants. Over the last three years, as a result of the introduction of this technique into large areas of wheat fields, this kind of insects was effectively got under control in Hebei province.
