茶尺蠖 Ectropisobliqua Warren 是浙江杭州、绍兴,安徽宣郎广,江苏宜兴等茶区的主要茶树害虫。由于年发生6~7代,繁殖力强,为害严重,因而用药频繁,费用甚大,并带来了茶叶上农药残留等项问题。如何探索其他防治途径,减少施药次数,降低农药用量,特别是如何在农业防治基础上,将化学防治、生物防治结合起来,是当前茶尺蠖防治研究上的主要课题。关于茶尺蠖寄生天敌过去报道甚少。1973年对我系茶园以及杭州茶叶试验场部分茶园考查结果,获得幼虫期寄生天敌四种,即绒茧蜂两种,瘦姬蜂一种,线虫一种,均单寄生。从6到
Ectropisobliqua Warren tea is the main tea tree pests in Hangzhou, Shaoxing, Anhui Xuan Lang, Jiangsu Yixing and other tea areas. As the 6 to 7 generations occur, fertility is strong, serious damage, so frequent medication, the cost is very large, and brought on the tea pesticide residues and other issues. How to explore other ways to control, reduce the frequency of pesticide application and reduce the amount of pesticides, especially how to combine chemical control and biological control on the basis of agricultural prevention and control are the main topics in the current research on prevention and control of Tenebrio molitor. Parasitic natural enemies on the tea scallop rarely reported in the past. 1973, Department of tea plantations in Hangzhou and Hangzhou, part of the Tea Field test field test results obtained four parasitoids natural enemies of larvae, that two calyx bee, a species of lepidoptera, nematode, a single parasitism.
