The numbers of RIFA and local ants were monitored by pitfall traps with 2-4 months interval followed by bait broadcasting. Data from four given periods among totally 14 monitoring courses were chosen and defined as initial stage (Ini.), middle stage (Mid.), late stage (Lat.) and terminal stage (Ter.) of control. Two small plots, A2 and D4, were selected to investigate the detailed changes in the numbers of ants over the 14 monitoring courses. Overall patterns suggest that the population of RIFA declined rapidly after control taking place and has been suppressed until the end of this study. All captured local ants comprised of 33 species, 19 genera, and 4 subfamilies in Formicidae. The compositions of ant fauna are different in study areas, which give raise the diverse make-up of dominate and sub-dominate species. In general, however, the dominate and sub-dominate species in distinct areas were composed of Myrmicinae and Formicinae. The overall richness and abundance of local ants in the campus seem not to be affected after RIFA was controlled by bait. Considering three different diversity indices, the diversity of the local ant populations significantly decreased after treatment and then increased gradually and slowly. However, it did not reach the level as found in the initial stage of invasion. The dynamic relationships among ants found in the campus suggest that not only the interspecific competition did exist under the pressure of RIFA and bait but also native ant species may be impacted by bait that RIFA can not occupy because of low population density. Based on the results obtained from this study, the control strategy might be modified to protect the local ant species by decreasing the amount of bait applied in the field and integrating the ants characterized by better competition ability as potential management agents. In this way the eradication program may gain additional benefits, particularly during the late stage of control, the likelihood of recolonization of RIFA could be minimized by the integration of chemical and biological controls.中文摘要……………………………………………………………………………i文摘要…………………………………………………………………………ii錄……………………………………………………………………………………iv次………………………………………………………………………………vi次………………………………………………………………………………vii、 前言………………………………………………………………………………1、 往昔研究…………………………………………………………………………4、 入侵紅火蟻生態之基礎研究………………………………………………4、 入侵紅火蟻對被入侵地生態的衝擊………………………………………5、 餌劑對於當地土棲螞蟻的影響……………………………………………6、 材料與方法………………………………………………………………………8、 試驗地點概述………………………………………………………………8、 調查及研究方式……………………………………………………………9、 掉落式陷阱設置……………………………………………………………10、 回收後處理…………………………………………………………………10、 鑑定檢索……………………………………………………………………11、 鑑定圖卡與標本留存………………………………………………………11、 統計分析……………………………………………………………………12、 結果………………………………………………………………………………14、 入侵火蟻族群概況…………………………………………………………14、 台北大學非入侵紅火蟻的土棲螞蟻群落概況……………………………16、 台北大學當地螞蟻優勢物種及群落組成分析……………………………22、 使用餌劑防治入侵紅火蟻對於當地螞蟻群落的影響分析………………24、 台北大學校區內氣候因子對於當地螞蟻群落的影響分析……………29、 可能與入侵紅火蟻競爭的當地螞蟻物種分析推測………………………30、 當地非入侵紅火蟻的土棲螞蟻多樣性指數分析…………………………33、 討論………………………………………………………………………………40、 入侵火蟻族群概況…………………………………………………………40、 台北大學非入侵紅火蟻的土棲螞蟻群落概況……………………………41、 台北大學當地螞蟻優勢物種及群落組成分析……………………………42、 使用餌劑防治入侵紅火蟻對於當地螞蟻群落的影響分析………………43、 台北大學校區內氣候因子對於當地螞蟻群落的影響分析……………44、 可能與入侵紅火蟻競爭的當地螞蟻物種分析推測………………………45、 當地非入侵紅火蟻的土棲螞蟻多樣性指數分析…………………………48、 結論………………………………………………………………………………50、 參考文獻…………………………………………………………………………51、 誌謝………………………………………………………………………………55、 附錄………………………………………………………………………………57application/pdf1614229 bytesapplication/pdfen-US入侵紅火蟻當地物種多樣性競爭防治Solenopsis invictanative antdiversitycompetitioncontrolthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/181775/1/ntu-97-R94632005-1.pdf
