昆虫寄生线虫与林业害虫的防治

本文综述了近２０ 年来国内外利用昆虫寄生线虫防治林业害虫的进展。指出自然存在的昆虫寄生线虫，是一类防治害虫的宝贵生物资源，它们对害虫种群起着一定的控制作用。尤其是索科、新垫刃科、斯氏科、异小杆科的昆虫寄生线虫，已大量成功应用于控制树蜂、根象甲、木蠹蛾类害虫等。我国自１９８５ 年从澳大利亚引进大量离体培养昆虫病原线虫技术以来，已在北京、天津、福建、湖北、辽宁、吉林等地开展了防治桃小食心虫、核桃举肢蛾、李实蜂、相思拟木蠹蛾、多纹豹蠹蛾、小木蠹蛾、桑天牛、桃红颈天牛、杨锉叶蜂、蛴螬等多种林业害虫的林间试验，取得了可喜的成就

UTILIZATION OF ENTOMOGENOUS NEMATODES FOR CONTROL OF FOREST INSECT PESTS

The advances in utilization of entomogenous nematodes for control of forest pest insects are reviewed in this article. Entomogenous nematodes are an important biological control agent in depressing of the population of their host insects. Specially the nematodes of Mermithidae,Neotylenchidae, Steinernematidae and Heterorhabditidae are used on large scale, successfully controlling woodwasps, weevils, carpenter moths. The mass production techniques were introduced from Australia in 1985. It has been promoting the progress in control of insect pests with entomopathogenic nematodes in China. Various insect pests are tested in field trials in Beijing, Tianjin, Fujian, Hubei, Liaoning, Jilin and so on. The tested insects include Carposina niponensis, Atrijuglans hetauhei, Hoplocampa spp., Arbela bailbarana, Zeuzera multistrigata, Holcocerus insularis, Apriona germar, Aromia bungii, Pristiphora beijingensis, scarabs and so on. In the field trials the results indicate that entomopathogenic nematodes are the effective bio control agents in the cryptic insect pests.
