| 摘 要： | 两种生物农药对灰斑古毒蛾2龄幼虫的野外防治结果表明,5%桉油精乳油和苏云金杆菌(8 000 IU/mg)在施药后3 d的防治效果分别为51%和18.3%,两者之间差异极显著;施药后6 d防治效果均达到90%以上。两种生物农药都有一定的持效性,在野外都能够很好的控制灰斑古毒蛾,相比之下5%桉油精乳油的防治效果优于苏云金杆菌。

| Abstract: | Control effect of two biotic pesticides on Orgyia ericae larvae in the 2nd instar was studied.The results showed the control effects of Bt(8 000 IUmg) and eucalyptol 5% were 18.3% and 51% 3 days after the application.There was significant difference at 0.01 levels in the control effects between the two pesticides.Control effects of the two pesticides were above 90% 6 days after the application.They could effectively control O.ericae and eucalyptol 5% was better than Bt. |
