Abstract: 為評估在台灣利用餌劑防治入侵紅火蟻(Solenopsis invicta)的可能性，本試驗以台北大學三峽校區作為基地，分別試驗３種入侵紅火蟻緊急防治用藥，包括百利普芬（0.5% Pyriproxyfen）、賜諾殺(0.015% Spinosad)及芬普尼(0.00015% Fipronil)的防治效果。本試驗自第一次施藥後兩週起，每２個月再施藥１次。施用的藥劑及用量為百利普芬及芬普尼２ kg/ha，賜諾殺３ kg/ha，防治效果之評估則以掉落是陷阱法，在試驗區內每隔２０m設置一個密度調查偵測管，偵測後２４小時回收偵測管，並計算管中的火蟻數量。偵測日期的規劃為第１次施藥前進行偵測１次，之後，再施藥的１～２星期前各實施偵測１次。從２００４年１１月１０日起，經過４次的施藥後，證實供試的３種餌劑在台灣對於入侵紅火蟻有明顯的防治效果，各處理之防治率達９８％以上。
In this study, we attempted to determine the effectiveness of various
baits to control the red imported fire ant (RIFA, Solenopsis invicta Buren) in
Taiwan. National Taipei University’s (NTPU) Sansia campus was used as the
experimental site to assess the control effect of three kinds of bait on the
RIFA. The baits used during the study were Esteem® Ant Bait (0.50%
Pyriproxyfen w/w), Cease Fire (0.00015% Fipronil), and Justice Fire Ant Bait
(0.015% Spinosad). The respective baits were applied at dosages of 2, 3, and 2
kg/ha every 2 months. The effect of baits on controlling the RIFA was
evaluated using the pit-fall trap method by establishing traps at 20-m
intervals on the campus. These traps were retrieved after 24 h and the
number of RIFAs trapped was calculated. We monitored RIFA density once
before the application of the baits, and then in the second, fourth, and eighth
weeks after application of the baits. The result of the study revealed that
after four applications of the baits, the control rate in each experimental area
exceeded 98%.
