前言油松球果小卷蛾(Gravitarmata mar-garotana Hein),是我省以至国内严重危害松类球果和枝梢的重要害虫之一。1973年前,我们曾与有关单位协作,摸索了航空化学、人工化学等行之有效的防治方法,并在生产中推广应用。但化学防治方法,也存在一些缺点。为了在现有防治方法的基础上,探讨新的防治途径,我们应用赤眼蜂于油松球果小卷蛾卵期进行了防治试验和示范。赤眼蜂可防治多种鳞翅目害虫。但国内外以往尚未见有应用赤眼蜂防治油松球果小卷蛾的正式报导。1978年我们进行小型试验时,应用的蜂种有松毛虫赤眼蜂 Trichogramma dend-rolimi Motsumura 和拟澳洲赤眼蜂 Trich-
Introduction Gravitarmata mar-garotana Hein is one of the most important pests in our province and even in China that seriously endangered pine cones and shoots. Before 1973, we worked with relevant units to explore effective methods of prevention and treatment, such as aviation chemistry and artificial chemistry, and promoted their application in production. However, chemical control methods, there are some shortcomings. In order to explore new ways of prevention and treatment based on the existing control methods, we used Trichogramma preponderate test and demonstration in the egg stage of Pinus tabulaeformis. Trichogramma can prevent a variety of Lepidoptera pests. However, at home and abroad in the past have not yet seen the application of Trichogramma repellent control Pinus small-headed moth official report. When we conducted a small-scale experiment in 1978, Trichogramma dend-rolimi Motsumura (Trichogramma dendrolimi) and Trich-
