Abstract: 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.
