在新疆用微孢子虫对3种草原蝗虫进行室内感病性试验,结果不同种蝗虫的感病率差异很大,红胫戟纹蝗的感病率高达83.5%,而意大利蝗和西伯利亚蝗仅分别为34.5%和17.7%。用飞机在草原喷洒,微孢子虫饵剂每100克加50%马拉硫磷4ml和10ml,对意大利蝗和红胫戟纹蝗虫口减退率可增加到76.7%和76.0%,明显高于单用微孢子虫饵剂的杀虫效果。作者认为在一般蝗虫发生年份,单用微孢子虫饵剂可压低虫口到防治指标(10头/m2)以下,蝗虫发生量大的年份,采用加微量农药的微孢子虫饵剂,既可提高防效,也可比单用农药减少对环境的副作用
In China, 3 species of grassland locusts were tested for their susceptibility to internode disease by microsporidia in Xinjiang. The results showed that the prevalence of different locusts varied widely, with a high prevalence of 83.5%, while the locusts and Siberian Locusts were only 34.5% and 17.7% respectively. Spraying on grassland with airplanes, the microsporidian bait dose per 100 grams plus 50% malathion 4ml and 10ml, to Italian locusts and red tibia halberd locust mouth reduction rate can be increased to 76.7% and 76.0% Significantly higher than the single use of microsporidian bait insecticidal effect. The author believes that in the general year of locust occurrence, the single microsporidian bait can be used to lower the insect population to below the control index (10 heads / m2), and the locust occurrence amount is large. Control effect, but also can reduce the side effects of the environment than single pesticide
