Abstract：
With global warming, the northern overwintering limits of the migratory rice pests, Nilaparvata lugens (Stl)、Sogatella furcifera (Horváth) and Cnaphalocrocis medinalis Guenée in China may move further north. We investigated the actual overwintering boundaries of these pests by sampling potential overwintering rice fields in the early spring of 2008、2010 and 2011 in south China according the national standard of rice planthopper and riceleafroller investigation criteria（GB/T 157941995 and GB/T 157931995）. Based on this investigation, we conclude that the overwintering boundaries of all three pests were similar to those previously reported in the 1970-1980. Through comparison of variation in monthly mean
temperature between the winters of 2008、2010、2011 and 1978-1981, we found that the mean temperature of January 2010 was above average whereas that in 2008 and 2011 were below average. Therefore, these three year’s data can not reflect the true
effect of global warming on these three pest’s northern overwintering boundary.
