一株从内地黄脊竹蝗虫尸中分离到的类产碱假单胞菌致病菌,经室内的感染试验表明,对青海、四川草地的优势种蝗虫具有较好的感染致死作用。用10~(10)活菌体/mL剂量的菌剂处理玉米,喂饲以中华坳蝗为主的草地蝗虫,死亡率达80.3%。对不同种蝗虫的感染致死率有明显差异,对东亚飞蝗的致死率为48%。对草地粘虫、草原毛虫、黑绒鳃金龟等害虫也有一定致死力。田间小区的治蝗效果达80%以上。 A strain of Pseudomonas aeruginosa isolated from the Huangjihu locust corpse of the mainland showed that it had a good lethal effect on the locusts of dominant species of grassland in Qinghai and Sichuan grasslands. Maize was treated with 10 ~ (10) viable bacterial cells / mL and fed on grasshoppers dominated by Caenorhabditis elegans, with a mortality rate of 80.3%. The infection rate of different species of locusts have significant differences in mortality, mortality of migratory locusts in East Asia was 48%. On the grass armyworm, grassland caterpillars, black velvet gill beetles and other pests also have a certain lethal force. Field locust control effect of more than 80%.
