中文摘要：
在深圳市龙岗区和宝安区对氟磺酰胺复配毒饵进行药效评价，试验结果表明，施药后3～15 d，龙岗实验区蚁巢周围均有死亡工蚁陆续出现。第7 d时，0.75%氟磺酰胺复配毒饵防治效果为16.99%，第28 d时防治效果达47.43%，在试验结束的第140 d时防治效果达97.93%；对照药剂0.5%氟磺酰胺毒饵对红火蚁Solenopsis invicta Buren的防除效果迅速，在第7 d防治效果达50%以上。在宝安实验区，蚁巢的防治效果也随施药后时间的延长而增加，第28 d的防治效果为51.65%，试验结束时防治效果达到94.72%；对照药剂0.5%氟磺酰胺毒饵42 d防治效果达最大值为92.88%。上述结果显示，0.75%氟磺酰胺复配毒饵具有较快压低红火蚁种群密度，持效控制实验区红火蚁种群的特点。
英文摘要： The control efficacy of mixture bait of 0.25% flursulamid and 0.50% insect growth regular (IGR)on the red imported fire ant Solenopsis invicta Buren was studied in field in two districts in Shenzhen, Guangdong province. The results in Longgang district showed that a large number of individuals of various castes of the imported fire ant died during day 3-15 after the bait application; the control efficacy of flursulamid mixture reached 16.99% and 47.43% on day 7 and 28, respectively, 97.93% after application when the test ended, while the control efficacy of 0.5% flursulamid bait is above 50% within one week. In Bao’an district, the control efficacy is 51.65% on day 28 after application of flursulamid mixture bait and 94.72% when the test ended, while the control efficacy of 0.5% flursulamid bait reached the peak value of 92.88% on day 42 after application. Based on the results from the two districts, we suggest that the mixture bait of 0.25% flursulamid and 0.50% IGR is a comparable fast acting and long lasting product against the imported red fire ant.
