摘　　要：目的调查黑龙江省抚远县黑瞎子岛鼠形动物种类分布、种群组成、季节消长和染体外寄生虫情况。方法采用夹夜法捕获鼠形动物,收集体外寄生蚤和革螨。结果在黑瞎子岛共捕获鼠形动物899只,计3目5科7属8种,总捕鼠率为24.1%,优势种为红背鼠平(36.7%)、黑线姬鼠(33.8%)和东方田鼠(21.4%);不同生境和月份鼠形动物种群组成有所不同;2种生境中鼠形动物在4-10月均有活动,高峰期均在9月;东方田鼠在6和9月出现2次高峰,红背鼠平和黑线姬鼠均在9月出现1次高峰;褐家鼠的染蚤率(42.9%)及指数(2.1)最高;褐家鼠的染革螨率(57.1%)及指数(4.3)也最高。结论摸清了黑瞎子岛鼠形动物种群组成,为开展鼠类的生态学、鼠类与疾病及防治研究提供了依据。Objective To investigate the species distribution, community composition, seasonal fluctuation of activity, and ectoparasites in the murine-like animals on the Heixiazi Island of Fuyuan county, Heilongjiang province, China. Methods The night trapping method was used to capture murine-like animals, and parasitic fleas and gamasid mites were collected from their body surfaces. Results A total of 899 murine-like animals （8 species, 7 genera, 5 families, and 3 orders） were captured on the Heixiazi Island; 24.1% of them were rodents, and the dominant species were Myodes rutilus （36.7%）, Apodemus agrarius （33.8%）, and Microtusfortis （21.4%）. The community composition of murine-like animals varied in different habitats and months. In the 2 habitats, the activities of murine-like animals were seen during April to October and reached the peak levels in September. M. fortis showed peak activity in June and September; M. rutilus and A. agrarius showed peak activities in September. Rattus norvegicus had the highest flea infection rate （42.9%） and flea index （2.1）, as well as the highest gamasid mite infection rate （57.1%） and gamasid mite index （4.3）. Conclusion This investigation provides a basis for the research on the community composition and ecology of murine-like animals and the control of infectious disease caused by murine-like animals on Heixiazi Island.
