我国草原虫害生物防治技术应用现状

摘要

In order to provide detailed information on the development and application of biological technolo-gy for controlling the pest insect in rangeland in China,the technologies,including Nosema locustae,Metarhiz-ium flavoviride,Pseudomonas pseudoalcaligenes,nuclear polyhedrosis viruses,avermectins,herding chicken and duck,attracting Sturnus roseus,azadirachtin,matrine and matrine-nicotine were introduced based on reviewing the literatures and research word.And the application and extension work,including microbial pesticide,agricul-tural antibiotic,natural enemy and botanical pesticide,were summarized.Some suggestions related to important problems existing in application were also provided.%为了让更多的人了解我国草原虫害生物防治技术应用情况，在查阅文献的基础上，结合我国草原虫害防控工作现状，回顾了草原虫害生物防治工作的进展历程，详细介绍了在推广工作中蝗虫微孢子虫、绿僵菌、类产碱假单胞菌、核型多角体病毒、阿维菌素、牧鸡牧鸭和人工招引粉红椋鸟、印楝素、苦参碱、烟碱·苦参碱等生物药剂和天敌控制技术的研究进展及在草原上的应用现状。最后，总结了近10年我国草原虫害生物防治技术的应用情况，指出我国草原虫害生物防控正在形成由微生物农药、农用抗生素、天敌利用、植物源农药等多种技术构成的新型格局，并针对防治工作中存在的主要问题，提出了对策建议，为今后开展相关研究和工作提供技术支持和参考依据。
