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。
Objective To investigate the species composition and seasonal fluctuation of rodents at Xunke Port in Heilongjiang Province. Methods Catch the Japanese law in arable land, forest margin grassland and river embankment habitat. Results In 2009, 1 117 rats were caught in 3 habitats in Xunke Port of Heilongjiang Province, including 9 families, 3 families, and 8 rats. The dominant species in the Xunke Port area is Apodemus agrarius (43.42%). Apodemus agrarius is the dominant species of cultivated land (68.63%) and river embankment (37.66%); redback mouse is the dominant species of forest margin (43.94%). The seasons of rats were as follows: Apodemus agrarius, Apodemus aganum and red-backed mice averaging 12 months, Mus musculus 9 months, Rattus norvegicus 8 months, black-hamster 7 months, Tail squirrel and rat are 5 months. During the entire season, Apodemus agrarius showed two peaks on a month. There was only one peak of redback mouse, Apodemus, Mus musculus, black hamster and long-tailed hamster. Conclusion This investigation provides a scientific basis for the study on the species composition, ecology and control of rats in the Xunke Port of Heilongjiang Province.
