中文摘要 | 根據77年9 月至78年11 月在南州糖廠構內畜殖場調查結果,棲息在畜殖場內的鼠 類以屋頂鼠 (Rattus rattus L.) 和溝鼠 (R. novegicus B.) 為主,前者約佔 66.6%, 為 優勢鼠種, 後者佔 29.9 %; 另捕獲食蟲目 (Insectivora) 之臭鼩鼱, 俗稱錢鼠 (Suncus muri- nus L.),佔 3.5 %。在一年三個月的調查期間未曾捕獲蔗田中常見之野鼠類。 屋頂 鼠多棲息在豬舍的屋頂上,但在屋頂上與地面上的被捕獲數則相近,分別佔 51.8 % 和 48.2 %; 而溝鼠則主要棲息於豬舍外的空地,96.4% 的個體均在地面上捕獲。 以鐵夾 及捕鼠籠捕殺之結果, 總捕獲率為 33.5 %, 在 3 月及 8 月各呈現一個高峰。 屋頂鼠於 8-11 月為發生高峰期,4 月最低。溝鼠則以 12 月至翌年 6 月間為發生高峰,7 目以後逐 漸下降, 至 10-11 月最低。 除冬季較低外,二種鼠類整年之懷妊率頗高, 屋頂鼠平均為 36.7 %,溝鼠為 22.1 %。平均每胎懷妊子鼠數屋頂鼠為 5.8 隻,溝鼠為 8.3 隻。 |
英文摘要 | Trapping of rats in the hog farm of Nanchou Sugar Mill during September 1988 to November 1989 indicated that the roof rat. Rattus rattus L., and the Norway rat, R. norvegicus B., were the major species composing 66.6% and 29.9% of the total capture, respectively, and the remaining 3.5% was Suncus murinus L. (Order: Insectivora). None of the species was found during the trapping period in sugarcane fields. Although most roof rats inhabited the roof of hog house, the numbers of roof rats captured from the roof and the ground of the hog house were almost the same, 51.8% and 48.2% of the capture, respectively, while 96.4% of Norway rat were captured on the ground around the hog house. Capturing of the rats with steel and living traps showed that the Percentage of the total capture was 33.5%, with two peaks in March and August. The population of roof rats fluctuated moderately, with a high percentage of trappings in August to November and the lowest in April. A high trapping of Norway rats was found in December to June, and then decreased gradually, with the lowest in October to November. Both species were found to have a high pregnancy rate almost all year round, an average of 36.7% for R. rattus and 22.1% for R. norvegicus, except in the winter. The averages of 5.8 and 8.3 young per litter were found for the roof rats and Norway rats, respecfively. |
