| 摘 要： | 利用广东省化州市1959—2008年气温资料及化州市病虫测报站1989—2008年稻飞虱、稻纵卷叶螟Cnaphalocrocis medinalis(Guenée)田间测报资料,运用统计分析方法分析了该地区气温变化与稻飞虱、稻纵卷叶螟发生的关系。结果表明:与1959—1988年1—4月各旬平均气温比较,1989—1998年气温变化不明显,而从1999—2008年呈明显的增温态势,这种气候背景使得上述2害虫发生期和发生程度随1—4月平均气温的升高而显著提前和加重,平均气温与发生期和发生程度的相关性达到显著或极显著水平。

| Abstract: | Temperature data from Huazhou City, Guangdong Province collected between 1959 and 2008, and forecast information on rice planthopper and Cnaphalocrocis medinalis （ Guenee ） abundance from the Huazhou Pest Testing and Report Bureau from 1989 to 2008, were used to determine the relationship the temperature and rice planthopper and, C. medinalis abundance. Comparison of the ten day temperature average between January and April from 1959 and 2008 indicates that temperature didn＇t vary markedly between 1989 and 1998. However, a marked increase in temperature was apparent from 1999 to 2008. The warmer temperatures during the latter period advanced the time of occurrence and abundance of both pest species. |
