摘要
青毛鼠(Rattus bowersii latouchei)是一种亚热带大型山鼠,主要分布于长江以南一些省份,盗食各种粮食、果实、树皮、嫩叶、香菇、竹笋等,食量大,给山区农、林业带来较大的危害。它也是钩端螺旋体病的宿主动物。作者在1977和1978年的10—11月在闽北武夷山区的邵武县和建瓯县进行了青毛鼠的生物学调查。现将调查结果报告于下。
A biological survey of Rattus bowersii latouchei had been made from October to November in 1977 and 1978 in Wuyi Mountian area(Shao-wu and Jian-ou),Fujian.216.rats had been caught.The traping rate was 2.33%, and the proportion of Rattus bowersii latouchei to other voles was 36.28%, the sexual ratio(♂:♀)was 55.38%,the average count of embryos was 4.22,ranging from 2 to 8. The highest body weight was 679 gms,the longest body length was 290 mm,and the largest skull length was 62.7mm.These results are greater than those reported in the past records. The body weights of different ages in the population of Rattus bowersii latouchei were as follows:juveniles:less than 230 gms;subadults:231-350 gms;adults 350-600 gms;olders:over 600 gms. This animal fed on alarge variety of material,but primarily on plants. The total amount of daily feeding was about a quarter of its body weight. One species of flea,three species of gamasid mites andsix species of trombiculid mites were collected from Rattus bowersii latouchei during this survey.
