| 摘 要： | 利用生绿Bt杀虫剂、1.8%阿维菌素、1.2%苦.烟乳油3种生物农药对灰斑古毒蛾OrgyiaericaeGermar 2~4龄幼虫进行了林间防治试验。结果表明,生绿Bt杀虫剂525 g/hm2对灰斑古毒蛾的防治效果为82.46%,最为经济有效;1.8%阿维菌素450 mL/hm2~150 mL/hm2对灰斑古毒蛾的防治效果在80.04%~100%之间,其中1.8%阿维菌素300 mL/hm2的防治效果最好。1.2%苦.烟乳油3种浓度的防治效果均为100%。 |

| Abstract: | Three pesticides,Bacillus Thuringiensis(Bt),1.8% abamectin and 1.2% matrine,were used against the larvae of Orgyia ericae Germain in the 2nd-4th instar in the forest.The results showed that the control effect of Bacillus Thuringiensis(Bt) at the dose of 525 g/hm2 was 82.46% and 1.8% abamectin at the doses of 450 mL/hm2,300mL/hm2 and 150 mL/hm2 could kill 98.19%,100% and 80.04% of the pest respectively;killing effects of three concentrations of 1.2% matrine were all 100%. |
