昆虫病原斯氏和导小杆线虫作为生物防治因子已受到世界各国的广泛重视,并得到了商品化的发展.自50年代,特别是7O年代末,我国从原捷克斯洛伐克、澳大利亚、美国等地引进了大批昆虫病原斯氏和异小杆线虫.同时也从土壤或自然寄主中分离出许多本国线虫种或品系,并对此类线虫进行了全面的研究,在昆虫病原线虫的种类调查和鉴定、田间大面积应用、安全性、共生细菌、大量繁殖等方面取得了可喜的进展.本文将综述这些方面的研究概况. As a biological control factor, Entomopathogen nematodes and insect-borne nematodes have been widely valued by all countries in the world and have been commercialized since the 1950s, especially the late 1970s, from the former Czechoslovakia, Australia and the United States Introduced a large number of entomopathogenic schistosoma and rodlet nematodes.At the same time from the soil or natural host in the separation of many native species or nematodes, and a comprehensive study of such nematodes, insect entomopathogenic nematode species in the investigation and identification , Field application of large area, safety, symbiotic bacteria, breeding and so on have made gratifying progress.This article will review the research overview of these aspects.
