| 中文摘要: |
| 饵剂诱杀是防控红火蚁Solenopsis invicta Buren最广泛和最有效的措施。本研究利用一种新型饵剂投放站（简称饵剂站）对比分析红火蚁〖JP2〗工蚁对0.08%茚虫威杀蚁饵剂及其载体的搬运量，并使用5 g/巢、10 g/巢、20 g/巢3种剂量的饵剂对田间红火蚁蚁巢进行单蚁巢处理，评价饵剂站对田间红火蚁的饵剂搬运量及防控效果的影响。结果表明，红火蚁工蚁对饵剂站内0.08%茚虫威饵剂及其载体的搬运量少于直接撒施处理方式的搬运量。施药24 h后，红火蚁工蚁对饵剂站内和直接撒施的0.08%茚虫威饵剂搬运量分别为14.84±3.18 g和17.71±5.88 g，差异不显著。使用饵剂站施用10 g、20 g饵剂处理28 d后，工蚁减退率、蚁巢减退率、蚁群级别降低率和综合防治效果均可达到90%以上，与直接撒施处理方式均无显著差异。虽然饵剂站会一定程度上降低红火蚁工蚁对饵剂的搬运量，但却不影响对红火蚁的防控效果，基于其防雨、防潮的优点，饵剂站可显著延长红火蚁防控的窗口期。 |

| Baiting is the most effective and widely utilized method for controlling the red imported fire ant Solenopsis invicta Buren. In order to evaluate the impact of a new bait dispensing station on the amount of bait transported by fire ant workers and their control effectiveness, the amount of 0.08% indoxacarb bait and its carrier transported by fire ant workers were compared using a new bait dispensing station versus direct broadcasting. Individual mound of red imported fire ant was treated with bait at doses of 5 g/nest, 10 g/nest and 20 g/nest to evaluate the effect of bait station on controlling S. invicta in the field. The results showed that both the amount of 0.08% indoxacarb bait and its carrier transported by fire ant workers in bait station were lower than with direct broadcasting. However, the transported amounts of 0.08% indoxacarb bait were recorded as 14.84±3.18 g for bait station treatment and 17.71±5.88 g for direct broadcasting treatment at 24 hours, with no significant difference. After treating with bait at doses of 10 g/nest and 20 g/nest in bait station for 28 days, the decline rates of worker, nest and ant colony level, as well as the combined control effect on S. invicta were over 90%. There was no significant difference between bait station treatment and direct broadcasting treatment. Although the bait station can partly reduce the amount of bait carried by fire ant workers, it still demonstrated good control effect against the red imported fire ant. The bait dispensing station offered the advantages of rain and moisture resistance, and significantly extended the suitable period for controlling the red imported fire ant. |
