| 为筛选出适用于云南热带雨林生态区的红火蚁Solenopsis invicta Buren防治药剂，通过7种杀虫剂对红火蚁蚁巢田间灭除效果试验测定。结果表明，20%多杀霉素悬浮剂（SC）、30%螺虫·噻虫嗪悬浮剂（SC）、70%吡虫啉可湿性粉剂（WP）、10%溴虫氟苯双酰胺悬浮剂（SC）和1%联苯·噻虫嗪颗粒剂（GR）对红火蚁蚁巢处理效果较好，药后1 d和10 d虫口减退率分别在95%和90%以上。其中10%溴虫氟苯双酰胺SC和1%联苯·噻虫嗪GR可作为红火蚁巢点处置的首选药剂；0.05%茚虫威饵剂（EB）速效性差，但药后10 d虫口减退率上升到86.8%。1.8%阿维菌素乳油（EC）药后1 d和10 d虫口减退率分别为89.3%和81%。这2种药剂可与前5种药剂交替使用。 |
| 英文摘要: |
| The effect of 7 insecticides on red fire ant nests in field was tested in order to screen the red fire ant control agents suitable for Yunnan tropical rainforest ecoregion. The result showed that 20% spinosad SC, 30% spirotetramat·thiamethoxam SC, 70% imidacloprid WP, 10% broflanilide SC and 1% bifenthrin·thiamethoxam GR had good control effect on ant nest. Decrease rate of insect number were at least 95% and 90% after 1 and 10 days of application. 10% broflanilide SC and 1% bifenthrin·thiamethoxam GR can be used as the first choice for the treatment of red fire ant nest. The rapid effect of 0.05% indoxacarb EB was poor, but the decrease rate of insect infestation increased to 86.8% after 10 d. The decrease rates at 1 d and 10 d were 89.3% and 81%, respectively, after 1.8% abamectin EC treatment. The two insecticides can be used interchangeably with the 5 mentioned above. |
