摘　　要：棕色田鼠是河南西部农作区的主要危害鼠种。１９９３年８月～１９９５年３月在河南省灵宝市程村乡对棕色田鼠的密度及其对农作物的危害程度进行了调查研究，并对小麦、黄豆２种不同作物地防治棕色田鼠的经济阈值进行了初步估算。把棕色田鼠对这２种作物的危害分为４个等级，小麦地防治棕色田鼠的经济阈值为１３３９只／ｈｍ２；黄豆地防治棕色田鼠的经济阈值为１８１１只／ｈｍ２，达到此密度应进行防治，否则将造成不同程度的经济损失。Mandarin vole is one species of primary destructive rodents in agriculture area in the west of Henan The population density and the harmful degree of Mandarin vole at Chengcun Country in Lingbao city of Henan province were studied from August 1993 to March 1995 ,and got the economic threshold of its prevention.Four harmful degrees were stipulated and got the threshold for wheat x=133 9 for soybean x=181 1. At this density of Mandarin vole, prevention must be started in order to get a good economic result.
