| 中文摘要: |
| 试验研究了0.045%茚虫威饵剂对红火蚁的田间防治效果，结果表明，施药25 d后0.045%茚虫威饵剂3、4、5 g/巢和0.015%多杀菌素饵剂15 g/巢处理的活动蚁巢减退率分别为90.2%、95.0%、97.5%、82.1%，工蚁减退率分别为84.4%、84.2%、90.2%、80.6%，蚁群级别降低率分别为97.7%、99.3%、100%、96.7%。提出了包括活动蚁巢数量、工蚁数量和蚁巢结构变化等方面的评价药剂对红火蚁防治效果的综合性指标。 |

| Field trials were undertaken to respectively evaluate the control effect of 0.045% indoxacarb (3 g, 4 g and 5 g indoxacarb for each active mound) and 0.015% spinosad (15 g for each active mound) on the red imported fire ant. The results showed that the control effects for active mounds were 90.2%, 95.0%, 97.5% and 82.1%, respectively, and those for the workers were 84.4%, 84.2%, 90.2% and 80.6%, respectively, after treatment for 25 days. The research of colony structure showed that their control effects on colony class were 97.7%, 99.3%, 100% and 96.7%, respectively, after treatment for 25 days. At last, the integrated index for evaluating the control effects of the insecticides on the fire ant was constructed. |
