小菜蛾(Plutella xylostella L.)是全球性分布的十字花科植物害虫,也是十字花科蔬菜重要害虫之一。近年来,杭州菜区也常因小菜蛾为害而造成重大损失。有的社队农药成本要占总成本的16.2%,全年每亩花药费11.66元,尚未控制为害。为此,我们于一九七三年至一九七四年,在浙江农业大学植保系和上海科教电影制片厂的指导和协助下,与杭州郊区井岗山大队贫下中农一起开展了小菜蛾的生物学研究。
Plutella xylostella L. is a globally distributed crucifer pest and one of the important pests of cruciferous vegetables. In recent years, Hangzhou food district is also often caused by the diamondback moth damage. Some communes and levies pesticide costs account for 16.2% of the total cost of the annual acanthopanax 11.66 yuan, not yet controlled.
