目的：本研究自2001年10月至2003年1月期間，調查台中市市場鼠類之分佈及探討不同餌料對鼠類之誘集效果。方法：研究期間於台中市8個傳統市場使用288個薛門氏活捉器進行捕捉，使用肉類（生豬肉片及烤香腸）及非肉類（乳酪、奶油麵包、甘藷及花生）食餌進行測試；實驗共捕獲64隻鼠類，於研究室進行種類辨別。結果：台中市8個傳統市場所捕獲鼠類包括：溝鼠(Rattus norvegicus)48隻及錢鼠(Suncus murinus)16隻。台中市市場鼠類捕獲率最高為南區(27.78%)及中區(27.78%)而北區(16.67%)及北屯區(16.67%)捕獲率最低。肉類及非肉類食餌捕獲率分別為44.79%及10.94%。以生豬肉片食餌捕獲率最高(34.37%)，其次為烤香腸(32.81%)。溝鼠顯著較錢鼠偏好肉類餌料(P<0.01)。各區以生豬肉片為餌共捕獲溝鼠19隻及錢鼠3隻。其中溝鼠以西區捕獲5隻(26.32%)最高，其次為南區捕獲4隻(21.05%)。以烤香腸為餌共捕獲溝鼠14隻及錢鼠7隻。其中錢鼠以東區捕獲3隻(42.86%)之捕獲率最高。結論：本研究顯示台中市區鼠類分佈及其食性在各區域間皆有顯著差異，並提供都會地區以不同食餌進行捕捉時之參考依據，以達最大捕獲成效。
Purpose: This study investigated the distribution of rats and the effect of different baits on rat entrapped in the traditional market in Taichung city from October of 2001 to January of 2003. Methods: We used Sherman live trap where were put at eight traditional markets in Taichung city to entrap rats. Meat-bait (pork, roasted sausage) and non-meat-bait (cheese, butter bread, sweet potato and peanut) were put in Sherman live trap, respectively. Results: Totally 64 mice were collected from eight traditional markets in this study. Forty-eight Rattus norvegicus and sixteen Suncus murinus were identified. Mice entrapping ratio was 44.79% in meat-bait group and was 10.94% in non-meat-bait group, respectively. Furthermore, 34.37% and 32.81% of mice entrapping was found in the meat-bait group by using pork and roasted sausage, respectively. In addition, different mice entrapping ratio were observed. South (27.78%) and Center (27.78%) districts were higher than those of North (16.67%) and Beitun (16.67%) districts, respectively. Meat-bait attracted Rattus norvegicus were much more than Suncus murinus (P<0.01). Nineteen Rattus norvegicus and three Suncus murinus were collected in the meat-baut group by using pork. Meanwhile, five Rattus norvegicus entrapping in West district (26.32%) and four Rattus norvegicus entrapping in South district (21.05%) were noted. Fourteen Rattus norvegicus and seven Suncus murinus were collected in the meat-bait group by using roasted sausage. Three Suncus murinus were collected in the meat-bait group by using roasted sausage. Conclusion: The results of this study indicated there was significant difference found in the distribution and eating characteristics of mice in Taichung city, which may provide the proper way to entrap mice by using different baits.
