新疆天然草地蝗虫病原微生物资源及应用前景

Application Prospects and Resources of Natural Grassland Locusts Pathogenic Microorganism in Xinjiang

对新疆天然草地蝗虫微生物资源进行研究分析,为以后保护利用这些珍贵资源提供依据。实地调查采集样本,并利用20余年的资料积累,分析整理新疆草地治蝗微生物资源,并对其应用前景进行讨论。新疆天然草地具有蝗虫痘病毒(locust EPV)、蝗虫寄生性线虫、蝗霉菌(Entomophthora grylli)等丰富的防治蝗虫的微生物资源。新疆天然草地蝗虫种类多,分布广,经常被各种病原物侵染,是多种微生物资源库。但与外地引入应用的技术成熟、商品化程度高的微孢子虫(Microsporidia)和绿僵菌(flavovirid Metarhizium)形成明显对比的是,本土微生物杀虫剂研制目前均未开展。实际上,保护利用好本土自然存在的蝗虫天敌资源,才是实现蝗虫灾害可持续控制的有效途径之一。

The study was conducted to research the resources of grasshoppers’ microbes on natural grassland in Xinjiang,providing basic knowledge to utilize this resources.The study included collection and investigation of microbes,analysis of data for 20 years,in Xinjiang,and proposed the utilization of the resoures.there are rich microbe resourses on natural grassland in xinjiang,like locust EPV、Entomophthora grylli、nemathelminthes,etc.There are many grasshopper species on grassland in Xinjiang,and often infected by microbe.In contrast with Microsporidia and flavovirid Metarhizium,the native microbial insecticide are not developed.To protect and to utilize native enemy of grasshopper are the basic way to realize sustainable control on grasshopper.
