黄脊竹蝗Ceracris kiangsu发生与气象因子的相关性研究

STUDY ON THE RELATIONSHIP BETWEEN YELLOW BACK BAMBOO LOCUSTS Ceracris kiangsu OCCURRED AND METEOROLOGICAL FACTORS

福建省长汀县1988年至1997年历年黄脊竹蝗Ceracris kiangsu Tsai发生面积与历年主要气象因子变量相关性进行研究。结果表明,黄脊竹蝗发生与气象因子有密切的关系,黄脊竹蝗发生与10月、1月、7月及4月、5月、6月份的气温,与9月、11月及1月、7月、6月份的降雨量,与6月、3月、7月及9月、2月份的日照时数相关密切。其相关性研究对预测和防治竹蝗有一定的指导意义。

This study is on the basis of both the occurred areas of yellow back bamboo locusts and the primary meteorological factors of calendar years from 1988 to 1997 in Changting County, Fujian Province.
