摘要
通过对9种植物源药剂进行药剂混配并与1种化学药剂（2．5％溴氰菊酯）对苜蓿上西花蓟马（Frankliniella occidentalis）进行防治比较试验，筛选出针对西花蓟马具有较好防效的复合植物源药剂。结果表明，10％柠檬草乳油250倍液与0．3％印楝素乳油800倍液以及0．3％印楝素乳油800倍液与2．5％鱼藤酮乳油800倍液两种组合具有显著效果，防效分别为76．5％～92．5％和79．9％～88．7%，具有见效快、持效期长的特点。
Botanical insecticides with high control effects on alfalfa thrips were selected through field tests. The results showed that 10% lemongrasstin with 0. 3% deltamethrin and 0. 3% deltamethrin with 2. 5% rotenone had significant effects, with the control levels at 76. 5%--92. 5% and 79. 9%--88. 7%, respectively. They had advanta- ges like fast and long effects.
