中文摘要：滥用农药导致粮食、蔬菜和水果内有毒农药高残留，严重威胁着人民的生命安全；利用生物防治害虫将提供更安全的食品和洁净的环境。Banker植物系统是利用非作物植物饲养及携带天敌的寄主或猎物，再利用天敌的寄主或猎物饲养和释放天敌。这些Banker植物就像是一个‘银行家（Banker）’，连续不断地供应‘货币’（天敌），使天敌从‘银行家’植物上扩散到有害虫的作物上防治害虫，是生物防治发展的一个重要方向。本文系统介绍了利用Banker植物为替代寄主饲养释放天敌防治害虫的最新进展，旨在推动我国更好地开展Banker植物系统及其相关理论与应用的研究。
英文摘要：
The indiscriminate use of toxic pesticides lead to high resisues in food, vegetables and fruits, resulting a serious threat to the safety of people’s lives. Biological control of pests will provide safer food and a clean environment. This article briefly describes the latest progress of using banker plant system to carry predatory or parasitic natural enemies to manage pests in vegetables and other crops. Banker plants continuously supply natural enemies, and like a bank (banker) to continuously supply currency; and the spread of natural enemies from the banker plant to the crop system to control crop pests. We would like to provide the most updated information in theory and utilization of banker plant system, and the most recent advance in using banker plant systems to promote biological control in China. We also discussed the pros and cons of using banker plant system in integrated pest management programs.
