评述了非生物因子、生物因子和施用技术对昆虫病原线虫田间应用效果的影响。选择适合防治寄主昆虫的病原线虫种类或品系是获得最佳田间防治效果的前提 ,而在昆虫病原线虫施用之前 ,应充分了解寄主昆虫的生长发育状态、土壤质地、结构、温度、湿度及土壤中的昆虫病原线虫天敌的情况 ,从而为昆虫病原线虫创造适宜寄生的环境条件。在昆虫病原线虫施用技术上 ,应掌握经济有效的施用剂量、次数和时期 ,并根据线虫的特点改进施用方法 ,以提高田间防治效果 The effects of abiotic factors, biological factors and application techniques on the field application of insect pathogenic nematodes were reviewed. The choice of pathogenic nematode species or strains that are suitable for controlling host insects is the prerequisite for obtaining the best control effect in the field. Before the application of the entomopathogenic nematode, the growth and development status of host insects should be fully understood, and the soil texture, structure, temperature, humidity and soil Of the insect pathogenic nematode natural enemies of the situation, so as to entomopathogenic nematode parasites to create appropriate environmental conditions. In the application of insect pathogen nematodes, should be to control the dosage, frequency and period of economic and effective application, and according to the characteristics of nematodes to improve the application method to improve the field control effect
