摘要:	The aim of this study was to investigate the possibility of eradicating the red imported fire ant, Solenopsis invicta Buren, in the hot, humid and rainy conditions of northern Taiwan. Thirteen hectares of the Shihmen Reservoir have been infected with these ants, with a total of 1 578 mounds. Pyriproxyfen was applied at a rate of 2 kg/hectare each season, for a total of four seasons. Surveys using visual examination, bait traps, as well as the population index method showed that the brood, the reproductive ants, and the worker ants within the nests were all significantly reduced 1 month after the first application of pyriproxyfen. Four months after the initial application there were no more brood or reproductive ants. After 8 months there were no longer any active mounds left, and 12 months later there were no more worker ants. After monitoring for 1 more year, it was ascertained that the red imported fire ants were eradicated. The percentages of decrease after 2, 4 and 6 months of treatment were 57.4%, 80.5%, and 98.2%, respectively.
