中文摘要：
为了解在全球气候变暖的背景下，我国水稻褐飞虱Nilaparvata lugens (Stl)、白背飞虱Sogatella furcifera (Horváth)及稻纵卷叶螟Cnaphalocrocis medinalis Guenée 3种迁飞性害虫越冬情况的新动态，于2008、2010、2011年1月底和2月底至3月初，全国农业技术推广服务中心测报处组织南方十余省基层植保部门参照稻飞虱和稻纵卷叶螟调查规范（GB/T 157941995和GB/T 157931995）调查了这3种迁飞性害虫的越冬情况。结果初步表明这3种迁飞性害虫的越冬北界与已报道的北界相比均没有明显的北移。通过这3年1月份温度距平与1978—1981年1月份温度距平的比较，除2010年属暖冬年份外，另2年均为冷冬年份，故这3年的越冬数据不能反映全球气象变暖对迁飞性昆虫的真实影响。
英文摘要：
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.
