黑龙江省逊克口岸鼠类的调查研究

目的调查黑龙江省逊克口岸鼠类的种类组成和季节消长。方法采用夹日法在耕地、林缘草地和江堤生境中捕鼠。结果 2009年在黑龙江省逊克口岸3种生境中共捕鼠1 117只,计3科8鼠9种。逊克口岸地区的优势种为黑线姬鼠（43.42%）。黑线姬鼠是耕地（68.63%）和江堤（37.66%）的优势种;红背鼠平是林缘草地（43.94%）的优势种。鼠的活动季节分别为：黑线姬鼠、朝鲜姬鼠和红背鼠平均为12个月,小家鼠为9个月,褐家鼠为8个月,黑线仓鼠为7个月,长尾黄鼠和花鼠均为5个月。在整个活动季节期间,黑线姬鼠月出现2次高峰;红背鼠平、朝鲜姬鼠、小家鼠、褐家鼠、黑线仓鼠和长尾黄鼠仅出现1次高峰。结论本次调查为黑龙江省逊克口岸鼠的种类组成、生态和防治研究提供了科学依据。

Investigation on rodents at Xunke port in Heilongjiang Province

Objective To investigate species composition and seasonal fluctuation of rodents at Xunke port in Heilongjiang Province. Methods Rodents were caught by the snap trap in the farmlands,in the woodside meadows and in the river banks. Results A total of 1 117 rodents were caught in 3 habitats of Xunke port in Heilongjiang Province during January to December in 2009, belonging to 3 families 8 genera 9 species. The dominant species was Apodemus agrariu~（ 43. 42% ） at Xunke port. A. agrarius was the dominant species in the farmland （68.63%）,and in the river banks （37.66%）. gyodes rutilus was the dominant species in the woodside meadows （43.94%）. The ac- tive seasons of rodents were in 12 months for A. agrarius ,A. peninsulae and M. rutilus ; in 9 months for Mus musculus ; in 8 months for Rattus norvegicus ;in 7 months for Cricetulust barabensis ; in 5 months Spermophilus undulatu~ and Eu- tamias sibiricus. During active seasons, there were 2 peaks for A. agrarius, and only one peak for M. rutilus ,A. peninsu- lae,M, musculus,R, norvegicus, C. barabensis and S. undulatus. Conclusion The investigation provides the evidence for the further study on species composition, ecology and control of rodents at Xunke port in Heilongjiang Province.
