摘要

為評估在台灣利用7.5%硼砂餌劑防治入侵紅火蟻(Solenopsis invicta Buren)的適用性，以桃園台電大潭電廠為試驗地，測試百利普芬(0.5% Pyriproxyfen)分別搭配賜諾殺(0.015% Spinosad)及硼砂(7.5% Borax)的防治效果。第1次施藥全區施用百利普芬，4個月後進行第2次施藥，分別施用賜諾殺及硼砂餌劑。施用藥劑及用量分別為百利普芬2kg/ha、賜諾殺3 kg/ha、硼砂3 kg/ha。在試驗8 個月期間，以調查試驗區內活動蟻巢數及陷阱內火蟻平均密度，估計其防治率，作為評估效果之依據。根據活動蟻巢數估算各評估區之最終防治率均達97.7%以上，顯示百利普芬－硼砂組合與百利普芬－賜諾殺組合對入侵紅火蟻均有明顯的防治效果。利用掉落式陷阱法進行火蟻密度的偵測，硼砂試驗區於施用硼砂餌劑後2個月，防治率達70%以上，3個月後更達83%以上，賜諾殺餌劑試驗區防治率亦達79%以上，顯見百利普芬餌劑搭配硼砂餌劑與百利普芬餌劑搭配賜諾殺餌劑對入紅火蟻的防治效果均良好。

Field experiments were conducted at Datan Power Plant, Guanyin, Taoyuan, Taiwan to determine the effectiveness of Fire Fire-Ants Bait (7.5% borax) for control of the red imported fire ant (RIFA, Solenopsis invicta Buren) in Taiwan. Control effect of Esteem (superscript ®) Ant Bait (0.5% pyriproxyfen) plus Fire Fire-Ants Bait (7.5% borax) or Justice (superscript ®) Fire Ant Bait (0.015% Spinosad) on RIFA were compared. The entire tested area was sprayed with the pyriproxyfen bait (2 kg/ha). After four months, the borax bait (3 kg/ha) and spinosad bait (3 kg/ha) were sprayed in each tested area. Throughout the eight-month experimental period, both treatments of pyriproxyfen plus borax and pyriproxyfen plus spinosad showed effective control of RIFA, and the rates of control were over 97.7% based on the number of active nests. When RIFA densities were monitored by the pit-fall trap method the rate of control by borax bait was over 70% after two months, and over 83% after three months, whereas the rate of control by spinosad bait was over 79% after three months. The study shows that the borax bait and spinosad bait have apparent controlling effect on RIFA.
