豚草在我国的生物防治研究进展

豚草是世界性恶性杂草，危害人类健康，严重影响农牧业生产。目前我国对豚草的防治方法主要有人工拔除、化学除草以及生物防治，人工拔除需要耗费大量的人力，化学除草则对环境和生态平衡造成严重的影响，因此，生物防治则受到了越来越多的关注。本文综述了豚草的分布、生物学特性以及在我国的传播扩散和危害，主要从利用病原菌、天敌昆虫、植物替代三方面介绍了生物防治豚草的研究进展，讨论了存在的问题及应对策略。

Research Advance on Biological Control of Ragweed in China

Ragweed is deletedous weed all over the world.They do harm to human health and affect the production of farming as well as animal husbandry. Anthropogenic uprooting, chemical control and biological control are primary ways to control ragweed in our country at present. However, anthropogenic uprooting need much manpower. Chemical control make serious effects on the environment and ecological balance. More and more attention is paid to biological control. This paper reviewed the origin, distribution, spreading and damage of ragweed. The research advance on biological control of ragweed was mainly introduced including using pathogenic bacteria, natural enemy insects and planting vicariousness plants. In addition, some challenges and possihle strategies with regard to managing ragweed were discussed.
