| 中文摘要: |
| 为了明确药剂灌巢剂量对红火蚁蚁巢迁移的影响。本研究利用不同剂量的锐劲特药液对红火蚁进行灌巢处理，在野外条件下观察了药剂灌巢后红火蚁蚁巢的迁移情况。结果表明：（1）当药液量与蚁巢体积的比例低于1.6时，会出现蚁巢迁移，药液量较大时，灌巢防治红火蚁可取得较好的防效；（2）随着灌巢药液量的增加，新蚁巢出现的个数明显减少，出现比例明显降低，新蚁巢的体积明显减小；（3）随着灌巢药液量的增加，新蚁巢出现的时间会延迟，处理药液量为2.5 L时，新蚁巢一般出现在1-3 d内，而药液量增加后，新蚁巢一般在3-5 d出现；（4）药剂灌巢防治后，红火蚁会在距处理蚁巢1-7 m范围内建立新蚁巢，不同药液量处理之间没有明显差异，新蚁巢出现的位置没有明显的方位取向。为避免灌巢不彻底导致蚁巢迁移，应保证灌巢用药量充足，推荐药液量为蚁巢体积的2倍以上。 |

| In order to clarify the effect of drench insecticide dose on the nest movement of Solenopsis invicta Buren. The nest movement of S.invicta was observed by drenching different doses of fipronil under the field condition. The result showed that: (1) The movement of treatment nest of S.invicta happened while the ratio of insecticide dose and nest size was lower than 1.6. The drench insecticide had excellent control effect on S.invicta when the drench insecticide dose was sufficient. (2) The number, occurrence probability and size of new nest of S.invicta significantly decreased during with the increase of insecticide dose. (3) The emergence time of new nest of S.invicta delayed with the increase of insecticide dose. The new nest of S.invicta appeared in 1-3 days under the treatment of 2.5 L dose, while in 3-5 days after the insecticide dose increasing. (4) The new nest of S. invicta would be established in the range of 1 to 7 miles away from the treatment nest, but there was no obvious difference among the treatment of different insecticide doses. The location of new nest of S.invicta did not show any obvious directionality. Therefore, in order to avoid the nest movement causing by incomplete artificial control, the recommended drench insecticide dose should be more than 2 times as much as the nest size of S. invicta. |
