摘要： 为探索并推广新型替代农药和防治措施，对2种害虫的田间危害情况进行连续多年的调查，基本探明了2种害虫在江西南昌的消长规律，在此基础上对几种新型化学、生物和植物源农药防治茶尺蠖和假眼小绿叶蝉的田间效果进行试验，探明了植物源农药茶蝉净和苦参碱、生物农药苏云金杆菌防治小绿叶蝉与茶尺蠖的效果，优选了防治茶尺蠖和小绿叶蝉的新型化学农药凯恩，防治小绿叶蝉的新型化学农药帕力特，总结了无公害茶园、绿色和有机茶园控制2种害虫危害的技术要点。研究结果显示：安装黄板茶园较不安装茶园平均虫口密度低39.8%；防治小绿叶蝉施药后3~14天防效，15%凯恩75.6%~95.9%，帕力特72.9%~93.2%，茶蝉净66%~72.5%，防效优于吡虫啉。防治茶尺蠖施药后3~14天防效，康欣373（苏云金杆菌）、15%凯恩、维特绿（0.3%苦参碱）、清源保（0.6%苦参碱）都在90%以上，防效优于联苯菊酯。

Abstract: There are two major pests in most of the tea garden in China. In order to decline the diseases by the two pests and reduce the loss. these had been to develop and promote a batch of synthetic pesticides. Such as Endosulfan, Dipterex, 2-dichlorovinylphosphate, Phoxim, Buprofezin,Carbamic acid, Imidacloprid, Acetamiprid, Cyfluthrin-beta, Bifenthrin.these control Empoasca flavescens Fabricius. and it control Eetropis Oblique Hypulina Wehrli that the Pesticide as Dimethrin、Fenpropathrin fenpropanate、Cartap hydrochloride dihydronereistoxin dicarbamate kartap neristoxin dicarbamate manohydrochloride、Diflubenzuron、Organic phosphorus and so on ,But it been found that some of the pesticides has great harm on the environment and human body with using for long time. So some pesticides have been disabled or restricted, and the insects have high resistance, the control effect descend root in drug concentration increased gradually. Therefore, It is imperative to explore and promote new alternative pesticides.this study was carried out on the two pests damage situation in the field of the continuous research for many years, The regular pattern have been founded in NanChang JiangXi of the two pests. Several new chemical drug, biological drug and plant source agrochemical drug have been experiment in the field for controlling Empoasca flavescens Fabricius and Eetropis Oblique Hypulina Wehrli. Indoxacarb can prevention and cure the two, Clorfenapyr can prevention and cure Empoasca flavescens Fabricius.And it have good effect on control Empoasca flavescens Fabricius and Eetropis Oblique Hypulina Wehrli that ChaChanJing,matrine and Bacillus thuringiensis. It summarized two kinds of the main technical points to prevention and cure Empoasca flavescens Fabricius and Eetropis Oblique Hypulina Wehrli in the pollution-free tea plantations, green and organic tea garden.
