目的通过总结分析云南省15个农田鼠情监测点16年监测数据,找出危害全省农作物的主要害鼠种类及分布、种群数量变动情况,为制定鼠害科学防治方案提供依据。方法采用t检验分析云南省农田鼠情监测点1994-2009年间鼠类混合种群密度变化,并用统计图表分析月份间农田鼠类混合种群密度变化。结果按农业种植业区划,将云南省农田害鼠划分为6个区域;全省年度间鼠密度变化不明显,而年内逐月农田害鼠种群数量变动呈双峰型,高峰期为4-6月和9-11月;主要农田害鼠有6种,占总捕获数量的88.32%。结论着重对全省农田鼠情监测工作点的数据进行分析,对农田以外地区害鼠的种群特征、活动分布、危害及其与农田害鼠的关系等有待进一步分析研究。
Objective To analyze the 16-year monitoring data of rodent control points on 15 farmlands in Yunnan Province and find out the main types and distributions of the harmful rodents that affect the whole province’s crops and the changes of the population quantity, so as to provide the basis for the scientific control plan of rodent pests. Methods The t-test was used to analyze the changes of rodent population density during 1994-2009 in farmland rodent surveillance in Yunnan Province. The distribution of rodents’ mixed population density in farmland during the month was analyzed with statistical charts. Results According to the zoning of agricultural planting area, the pest rats in Yunnan Province were divided into 6 regions. The annual density of rat pests in the whole province was not obvious. However, Month and from September to November. There are 6 main pests in the farmland, accounting for 88.32% of the total catch. Conclusion The data of farmland rodent monitoring in the province are analyzed emphatically. The population characteristics, activity distribution and harm of rodent pests outside the farmland and their relationship with farmland rodents need to be further analyzed.
