摘要
应用1．8％森得保可湿性粉剂、1．8％除虫菊·苦参碱水乳剂、1．2％苦·烟乳油3种生物农药对丽绿刺蛾（Latoia lepida Ctamer）3～4龄幼虫进行了林间防治试验。结果表明，森得保550g·hm-2对丽绿刺蛾的防治效果为90．13％，最为经济有效；1．8％除虫菊·苦参碱水乳剂450～150mL·hm-2对丽绿刺蛾的防治效果为83．29％-90．13％；1．2％苦·烟乳油750、650和550g·hm-2等3种浓度的防治效果均为100％，防治效果最好。
Control experiments of 3- 4 instars larvae of Latoia lepida by using 3 kinds of biological pesticides （ 1.8 % Sendebao wettable powder, 1.8% pyrethrum ＋ matrine emulsion in water, 1.2% Matrine） were conducted in forest. Result shows that 550 g . hm-2 Sendebao wettable powder have the most economical and effective control effect on Latoia lepida, being 90. 13% ;control effect of 450-150 mL . hm-2 1.8% pyrethrum ＋ matrine emulsion in water on Latoia lepida is 83.29%- 90. 13% ; control effect of 1.2% Matrine with 3 concentrations（750,650 ＆ 550 g . hm-2） are all 100% ,being the optimal.
