茶小卷叶蛾(Adoxophyes sp·)和茶卷叶蛾(Homona magnanima)被日本定为茶树栽培管理九类主要防治对象之害虫。防治费用开支很大,光是以卷叶蛾为防治对象,每年1.5亩茶园就要化费20000日元左右,并且农药的残留与对环境污染问题也甚突出,同时农药也杀灭了大量天敌,从而破坏茶园昆虫生态系统的自然平衡,导致害虫再增猖獗。为了克服此类弊端。日本从70年代开始探求防治卷叶蛾新的技术途径,其中两种卷叶
Adoxophyes sp. And Homona magnanima have been designated by Japan as pests for the control of nine major types of tea tree cultivation and management. Prevention and control costs are large, just to control leaf roller moths, 1.5 acres of tea will cost around 20000 yen per year, and pesticide residues and environmental pollution problems are also prominent, while pesticides also kill a large number of natural enemies, thus Destroy the natural balance of insect ecosystems in the tea plantation, causing the pest to proliferate again. In order to overcome such drawbacks. From the 1970s, Japan began to explore new technological approaches to the prevention and control of leaf roller moths, of which two were curled
