| 针对近年橙带蓝尺蛾 Milionia basalis 发生严峻的形势，为生产实践中提供更多可供选择的
高效低毒药剂，项目采用室内和林间测定相结合的方法，测定了 10% 高效氯氟氰菊酯悬浮剂、1.2% 烟 碱 · 苦参碱乳油、5% 氯虫苯甲酰胺悬浮剂、2% 甲氨基阿维菌素苯甲酸盐微乳剂、20% 除虫脲悬浮剂 5
种药剂对橙带蓝尺蛾 3 龄、5 龄幼虫的防治效果。室内测定结果表明，针对 3 龄幼虫，药后 5 d，前 4 种
药剂防治效果即可达 93.3% 以上；针对 5 龄幼虫，药后 7 d，前 4 种药剂防治效果达 90.5% 以上。林间测
定结果表明，药后 7 d，前 4 种药剂防治效果均可达 97.0% 以上。测定结果表明前 4 种药剂对橙带蓝尺蛾
3 龄和 5 龄幼虫均有较好的防治效果，药后 7 d 防效均在 90% 以上，但在 3 龄幼虫期前防治见效更快。因
此建议在橙带蓝尺蛾 3 龄幼虫前轮换施用前 4 种药剂，避免产生抗药性。 |

| Abstract: |
| In view of the serious situation of the occurrence of Milionia basalis in recent years, in order
to provide more effective and low toxic agents for production practice, different insecticide powders, such as
10% beta cypermethrin SC, 1.2% nicotine and matrine EC, 5% chlorantraniliprole SC, 2% Emamectin Benzoate
Microemulsion, 20% Diflubenzuron SC, were tested to control 3rd and 5th instar larva of M. basalis in the library
and field. The indoor results showed that for 3rd larvae, 5 days after applying insecticides, control efficiency of
the first four insecticides are above 93.3%; for 5th instar larva, control efficiency of the first four insecticides are
above 90.5% in the seventh day. The field results showed that control efficiency of the first four insecticides are
all above 97.0% in the seventh day. The results showed that control efficiency of the four insecticides are above
90.0% in the seventh day, but the controlling effect is faster before 3rd instar larvae. So it is suggested that the first
four insecticides should be applied to the 3rd instar larvae to avoid drug resistance. |
