Abstract: This study analyzed the light trap catches and field survey data of SBPH from 2000 to 2011 in Danyang and Ganyu, combining with meteorological data, the author used SAS to do correlation analysis between the average monthly temperature, precipitation and annual quantity of SBPH. The main results were as following:（1）Both in Danyang and Ganyu, the most serious year of outbreak of SBPH was 2007, it outbroke in light traps in Danyang and Ganyu at the same period in Spring, the harm caused by the first generation of SBPH in light traps is most serious, and in recent years, the trend occurred in advance, and the hazard caused by 4th, 5th generation has aggravated. （2）The average monthly temperature of overwinters, the average monthly temperature of the first generation adult occurrences and the precipitation of the first generation adult emergence had greater correlation to the annual quantity of SBPH.

摘要： 以2000-2011年江苏省丹阳市和赣榆县灯诱水稻灰飞虱和田间调查历史数据为资料，并结合气象资料，运用SAS软件对江苏省水稻灰飞虱年发生量和月平均温度、降水量等因子进行相关性分析。结果表明，丹阳市和赣榆县水稻灰飞虱大爆发年份均为2007年，春季灯下虫量同期突发，危害严重的为灯下第1代，且有发生提前的趋势，近年来，4、5代危害加重；第1代成虫发生时的气温和越冬气温，以及第1代成虫羽化时的降水量与灰飞虱年发生量的相关性较大。
