摘要: 对施用蝗虫微孢子虫后1~10年的草场中5种主要蝗虫种群中微孢子虫病的流行状况进行了研究,结果表明,蝗虫微孢子虫病能在蝗群中长期传播,蝗虫种群的感病率和感染指数呈波动趋势,随着施用后年限的增加,波幅变动范围趋于稳定。感染率波幅范围为20%~80%,感染指数为10%~41%;鼓翅皱膝蝗、白边痂蝗和毛足棒角蝗种群对微孢子虫病的感染指数,不同年份波动较大,短期内难以形成一个稳定的流行群体;而在小车蝗和宽须蚁蝗种群中引入微孢子虫4年后,感染指数下降,但能够形成比较稳定的感染群体。

Abstract: In the regions of treatment using Nosema Locustae in recent ten years,the percentages of infected grasshoppers by Nosema Locustae are 20%-80%,the infection exponents are 10%-41%.It was proved Nosema Locustae could spread in the population of grasshopper for a long time.After spraying,infection exponents showed stable trend with extending time.The infection exponents of Angaracris barabensis,Bryodema luctuosum luctuosoma and Dasyhippus harbipes were unstable in different years,it is difficult to establish infected populations in shorter period.But the proportion of Oedaleus asiaticus and Myrmeleotettix palpalis's infected population were stable relatively,after spraying Nosema Locustae for four years.It is important to improve controlling efficiency to grasshoppers using Nosema Locustae and control the grasshoppers below the level of economic damage.

Key words: Grasshoppers, Nosema locustae, Infection
