摘  要

陳昇寬、宋一鑫、林明瑩• 2005•雲嘉南地區入侵紅火蟻( Solenopsis invicta )分佈、監測及評估可能擴散之方向。臺南區農業改良場研究彙報 46:20-24。

調查火蟻現有發生區域與農耕地、公共設施面積之關係,並預測其築巢擴散之可能方向。苗圃內的入侵紅火蟻經長期防治下,以掉落陷阱法監測捕獲之數量從防除前之一陷阱一日 60隻,在5個月後即降至0隻,雖在94年4月20日曾捕獲0.08隻(24個陷阱中捕獲2隻),但至 94年8月25日 止均未再捕獲。

關鍵詞: 入侵紅火蟻、分布、監測、掉落式陷阱

Distribution, Monitoring and Estimation of the Possible Dispersal Direction of
Red Imported Fire Ant ( Solenopsis invicta ) in Yulin, Chiayi and Tainan Area

Chen, S. K., I. S. Sung and M. Y. Lin

Summary

The result of example discussed the relations between the nests of red imported fire ant and farming ground, and public facilities. We also predicted the possibility of the directions of the nest dispersals. During the long term eradication on Solenopsis invicta at the Chiayi county government nursery, we conducted the pit fall traps to monitor the S. invicta density. The results showed that 1 trap captured 60 S. invicta per day before eradication, and then dropped to zero S. invicta after 5 months. Although we captured 0.08 S. invicta (2 S. invicta among 24 pitfall traps) on April 20, 2005 , but no S. invicta were captured by August 25, 2005 .
