我国蔬菜害虫生物防治研究进展

我国是蔬菜生产、消费和出口大国,蔬菜害虫是影响蔬菜产量和品质,制约蔬菜产业发展的重要因素。传统化学农药的长期大量使用,不仅造成生态环境污染、影响食品安全,还导致害虫抗药性逐渐增强,因此,生物防治成为害虫综合治理的重要措施。我国生物防治技术经过几十年的发展,在天敌昆虫资源的发掘、应用、技术研发和配套措施等方面取得了显著的进步。本文综述了我国蔬菜害虫生物防治的研究和应用进展,并分析了当前存在的问题和发展趋势,以期为今后的害虫研究和防治提供思路。

Progresses in biological control of vegetable insect pests in China

Vegetable production, consumption and export are tremendous in China. Insect pests have a serious impact on the quality and yield of vegetables, and it has become the key factor restricting the development of the vegetable industry. With the long term use of chemical pesticides, the problems of environment and food safety were caused, and pests have developed serious insecticide resistance. Therefore, biological control measures play an important role in the integrated pest management. After decades of efforts, a great progress has been made in the resource discovery of natural enemy species, application, technology research and supporting technology. In this paper, researches and applications about biological control of vegetable pest insects in China are reviewed, and the current problems and development tendency in biological control are analyzed, which will provide the ideas for the further research and pest control.
