摘　　要：为了解蝗虫微孢子虫(Paranosema locustae)和绿僵菌(Metarhizium anisopliae‘acridum’)对蝗虫的防治情况,在农业部锡林郭勒草原有害生物科学观测实验站,对短星翅蝗(Calliptamus abbreviatus)和宽须蚁蝗(Myrmeleotettix palpalis)分别进行蝗虫微孢子虫、绿僵菌及两种药剂混合处理后,进行室内生测,记录28d的死虫数,并检测其感染情况。结果显示:单施蝗虫微孢子虫防治短星翅蝗,每头蝗虫的施用量为4.44×105个孢子,防治效果达65.09%。单施蝗虫微孢子虫防治宽须蚁蝗,每头蝗虫的施用量为4.44×104个孢子,防治效果达55.64%。混合施用蝗虫微孢子虫和绿僵菌防治草原蝗虫时,二者对每头蝗虫的施用量分别为4.44×104和1.11×106个,防效均可达到100%。与短星翅蝗相比,蝗虫微孢子虫对宽须蚁蝗的防效更好。In order to investigate the control efficiency of Paranosema locustae and Metarhizium anisopliae var.acridumon locust,an experiment was carried out by comparing of mortality and detected infection after feeding Calliptamus abbreviatus Ikovnn.and Myrmeleotettix palpalis Zub.with P.locustae or M.anisopliae var.acridumand the mixture of both,respectively,for 28 days.The experiment was carried out at the Ministry of Agriculture Pest Investigation Station in Rangeland.The results showed that the control efficiency was 65.09% and 55.64%,by only using 4.44×10^5P.locustae every C.abbreviatus and4.44×10^4P.locustae every M.Palpalis,respectively.The control efficiency was 100% by utilizing the mixture of 4.44×10^4 P.locustae and 1.11×10^6 M.anisopliae every grasshopper.P.locustae had stronger control efficiency on M.Palpalis than C.abbreviatus.
