茶尺蠖和假眼小绿叶蝉防治技术研究

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。

Prevention and Control Technology on Empoasca flavescens Fabricius and Eetropis Oblique Hypulina Wehrli

To explore and promote new alternative pesticides and prevention measures, for continues years we investigated 2 species of insect pests of field harm condition and basically proved their growth and decline law in Nanchang City in Jiangxi Province. Based on the above investigation results we studied the field effects of several new chemical, biological and botanical pesticides on Ectropis oblique Prout and Empoasca vitis and proved the effects of botanical pesticide（Chachanjing and matrine） and biological pesticide （Bacillus tburingiensis） on the control of them, and then the new chemical pesticide Kaien to control Ectropis oblique Prout and Empoasca vitis as well as Palite to Empoasea vitis were selected. We summarized the technical points of controlling of 2 species of insect pests in pollution-free, green and organic tea gardens. The results showed that the population of Empoasca vitis Gothe in the installation board tea garden was less 39.8% than others. When 3-14 days after drug, the control effect to Empoasea vitis Gothe were 75.6%-95.9% in Kaien （15% indoxacarb）, 72.9%-93.2% in Palite （chlorfenapyr）, 66%-72.5% in Chachanjing （nicotine）, they were better than imidacloprid in control effect, the control effect to Ectropis obliqua were more than 90% by Bacillus thuringiensis, indoxacarb, matrine when 3-14 days after drug, they were better than bifenthrin in control effect.
