Chinese. 近年来南方部分丘陵地区农田鼠密度有所回升,湖南省常宁鼠情监测点调查结果表明, 2010年1-4月平均鼠密度较2009年同期平均鼠密度上升1倍; 2010年5月农田鼠密度达到12.90%。常宁农田以黄毛鼠和黑线姬鼠为优势种, 分别占61.29%和29.03%, 繁殖指数分别为2.33和2.25, 黑线姬鼠繁殖指数高于洞庭湖丘岗区同期的平均值,体型较大的黄毛鼠和褐家鼠增加较快; 2011年4月江西新余市丘陵区的农田害鼠密度为11.97%以黑线姬鼠为优势种。对上述鼠害均需要采取控制措施。

To explore the population densities of rodent communities in hilly areas of South China, snap traps were used in farmlands of Changning of Hunan and Xinyu of Jiangxi in 2010.The results showed that the total density from January to April in 2010 was doubled compared to that in Changning in 2009,and trap success reached 12.90% in May 2010.In Changning, Rattus losea and Apodemus agrarius were dominant species, accounting for 61.29% and 29.03%,respectively,and reproductive indices were 2.33 and 2.25, respectively. In Xinyu, trap success was 11.97%,and A.agrarius was dominant species. It was suggested that some control measures should be conducted, and more attention should be paid to the rodent species with big body masses, such as R.norvegicus and R.losea, because they had high population densities in the moment.
