Abstract:         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.
