摘要： 摘要[研究目的] 研究植物源农药苦参碱、印楝素与矿物油两种复合液防治小绿叶蝉，跗线螨的药效。[方法]应用苦参碱、印楝素乳油与矿物油两种复合液；单剂苦参碱、印楝素；两种化学农药硫丹、乐果6种处理。在广西桂北茶园第二次小绿叶蝉高峰及跗线螨高峰前期进行田间防效小区对比试验。[结果]6种处理对小绿叶蝉校正防效：两种复合液药后2-7天分别高达86.54%--88.57%，药后14天仍达60.29%--58.59%，单剂苦参碱、印楝素校正防效：药后2-7天最高只达为64.94%--67.17%，两种化学农药硫丹、乐果校正防效：药后2天仅为52%--41.04%。6种处理对跗线螨的防效：两种复合液药后2-7天分别高达91.14%--93.67%，药后21天仍达68.03%--69.57%。单剂苦参碱、印楝素校正防效：药后2-7天也达74.19%--76.47%，药后14天仅为50.12%--51.18%。两种化学农药硫丹及乐果，药后2天为83.45%--70.54%，药后21天仅为37.53%--4.73%。[结论]两种复合液比其它4种处理在防治小绿叶蝉及跗线螨上显示出较好的防效及较长的持效期。两种复合液不仅能有效地控制小绿叶蝉及害螨，而且对天敌安全。可在有机茶园生产基地的茶叶生产中推广使用。

Abstract: Abstract：【OBJECTIVE】Study on the control effects of botanical insecticides matrine，azadirachtin and mineral oil agains Empoasca Vitis and Tarsonemidmites.【METHOD】To do the comparison experiment by using two complex liquid of matrine，azadirachtin and mineral oil , siple Dosage matrine and azadirachtin，two kinds of chemical pesticide of endosulfan and dimethoate,before the High Day for the second generation of Empoasca vitis and the peak of Tarsonemidmites in the north of Guangxi province.【RESULTS】The corrected control effects of the six kinds of mixture against Ectropis obliqua：The two complex liquids is 86.54%--88.57% after 2 to 7 days，it is 60.29%--58.59% after 14ds. The corrected control effects of siple Dosage Matrine and Azadirachtin is 74.19%--76.47% after 2 to 7 days，it is 50.12%--51.18% after 14ds. two kinds of chemical pesticide of endosulfan and dimethoate is 83.45%--70.54% after 2 to 7 days，it is 37.53%--4.73% after 14ds.【CONCLUSION】the two complex liquid have better effect and longer lasting time than the other treatments. The two complex liquids not only can do well on concroling agains the Empoasca Vitis and Tarsonemidmites，but also they are safe to the natural enemy which can be extended on tea-Harmless production.
