摘要： 【研究目的】研究植物源类杀虫剂苦皮藤素乳油对茶尺蠖等害虫防治效果。【方法】应用0.2%苦皮藤素乳油，500倍、1000倍和1500倍3个浓度，分别处理茶鲜叶放入果酱瓶中，接上茶尺蠖二龄幼虫，进行室内防效评价实验；应用1500倍进行大田防效试验；应用500倍、1000倍和1500倍3个浓度进行防治茶小绿叶蝉的田间防效小区对比试验。【结果】应用500倍、1000倍和1500倍3个浓度的0.2%苦皮藤素其结果表明；室内：0.2%苦皮藤素500倍，药后3天死亡率98.67%，1000倍的死亡率85.33%，1500倍的死亡率73.33%；大田防效：0.2%苦皮藤素1500倍药后10天防治茶尺蠖，防效为88.13%~90.69%；0.2%苦皮藤素500倍药后8天防治小绿叶蝉，防效为63.66%~80.11%。【结论】试验显示了该药剂对茶尺蠖有较好的防效和持效期，可作为植物源类杀虫剂在无公害茶叶生产基地上推广应用。

Abstract: 【OBJECTIVE】 The control effect of the botanical pesticide celangulin EC on pesticides was studied in this experimentation, especially Ectropis obipua hypulina Wehrli. 【METHOD】 In the control effect experimentation indoor, the tea leaves was dealed with 500,1000,1500 times 0.2 Percent Celangulin and were put into jam bottles and were put a certain number of the 2th instar larvae of Ectropis obipua hypulina Wehrli. The Control effect experimentation in land was used 1500 times liquor. The Control effect contrast experimentation of small parts of land on Empoasca flasvescems Feb. were used 500,1000,1500 times 0.2 percent celangulin. 【RESULTS】 The result of the experimentations indicate that the part used 500 times liquor’s death rate was 98.67% and the part used 1000 times liquor’s death rate was 85.33% and the part used 1500 times liquor’s death rate was 73.33% indoor after 3 days. And in land, using 1500 times liquors 10 days on Ectropis obipua hypulina Wehrli, the control effect is 88.13% to 90.69%. Using 500 times liquor’s 8 days on Empoasca flasvescems Feb., the control effect is 63.66% to 80.11%. 【CONCLUSION】 The experimentations indicate that the control effect of the liquor is good and the control effect lasts long. 0.2 percent celangulin, the botanical pesticide, can be used in a nuisance -free tea base.
