| 研究了高效氯氟氰菊酯微囊悬浮剂与二阶段法对红火蚁的田间防治效果。结果表明，0.25 g/L高效氯氟氰菊酯微囊悬浮剂施药后击倒红火蚁迅速，14 d后活动蚁巢减退率、工蚁减退率、蚁巢级别降低率、综合防治效果均达到100%。使用0.045%茚虫威饵剂搭配0.25 g/L高效氯氟氰菊酯微囊悬浮剂的二阶段法，5 d后红火蚁的活动蚁巢和工蚁数量均显著下降，14 d后活动蚁巢减退率、工蚁减退率、蚁巢级别降低率、综合防治效果均达到100%。结果表明,0.25 g/L高效氯氟氰菊酯微囊悬浮剂对红火蚁具有高效的控制作用，在实际使用时可根据防治面积的大小选择单独灌巢还是配合饵剂的二阶段法。 |
| 英文摘要: |
| Field trials were undertaken to evaluate the control effect of Lambda-Cyhalothrin microcapsule suspension and Two-Step Method on the red imported fire ant, Solenopsis invicta Buren. The results showed that S. invicta workers quickly killed by drenching of 0.25 g/L lambda cyhalothrin microcapsule suspension. Active nest reduction rate, worker ant reduction rate, nest grade reduction rate, and the comprehensive control effect reached 100% 14 d after drenching of nest.Combing 0.045%indoxacarb bait with drenching of 0.25 g/L lambda cyhalothrin aqueous capsule suspension was served as Two-Step Method, the number of active nest and workers significantly decreased 5 d after bait applicationa few active mound and S. invicta under control, active nest reduction rate, worker ant reduction rate, nest grade reduction rate, and the comprehensive controleffect reached 100% 14 d after bait application. Therefore, this results suggest that 0.25g/L lambda cyhalothrin microcapsule suspension could be used for control of S.mninvicta in the field. |
