用绿僵菌油剂在新疆山地草原对蝗虫进行了防治试验。喷药后采样 ,罩笼饲养从第 3天开始感病死亡 ,第 5天死亡明显增多 ,第 6天绝大部分蝗虫死亡。该绿僵菌在自然条件下对试验区内的 5种蝗虫具有相同的感染致病力。田间防效在第 15天为 6 0 .9% ,第 18天为 73.7%。
Metarhizium anisopliae oil locust in Xinjiang mountain grassland prevention and treatment experiments. Samples were taken after spraying and the caged cage was moribund and died from the third day. The mortality was significantly increased on the fifth day and most of the locusts died on the sixth day. Metarhizium anisopliae had the same pathogenicity to infection in five locusts in the experimental area under natural conditions. Field control efficacy was 60.9% on day 15 and 73.7% on day 18.
