摘  要：
采用温室盆栽试验研究了昆虫病原线虫Heterorhabditis bacteriophora-NJ施用剂量、施用次数和在盐碱土、风沙土及黑土等不同土壤类型条件下对东北大黑鳃金龟(Holotrichia diomphalia)幼虫防治效果的影响。结果显示,嗜菌异小杆线虫施用浓度在线虫5条/cm2~80条/cm2剂量时,施用2~3次,可有效地控制东北大黑鳃金龟幼虫,施用浓度对线虫防治东北大黑鳃金龟幼虫效果的影响较施用次数要大。在黑土、盐碱土和风沙土中,嗜菌异小杆线虫对东北大黑鳃金龟幼虫的防治效果都较高,其中盐碱土防效更好一些。表4,参24。

摘  要：
The experiments on using Heterorhabditis bacteriophora-NJ to control Holotrichia diomphalia Bates at the treating dosage,application times,and 3 soil types:salina soil,black soil,and sandy loam were conducted in greenhouse.The biocontrol efficacy of the dosage of 5-8 nematodes/cm2 and treating 2 times to control the soil pest is the best.Through main factor analysis,the result showed that the dosage of EPN used was more important than the application times.In salina soil,black soil,and sandy loam of soils,the efficacy of EPN against Holotrichia diomphalia Bates were all high with higher(63.334±15.06%) in salina soil.
