摘要： 以粘虫、稻飞虱为例，分析了气候变暖对害虫生长、繁殖代数、越冬界限、迁飞等生态学特征的影响。结果表明，气候变暖，积温增加将会使粘虫、稻飞虱的繁殖代数增加，越冬界限北移，迁飞范围扩大，从而使害虫的发生时间延长，危害程度加重。

Abstract: Taking armyworm[Mythimna separate(Waker)], rice planthopper (Delphcidac)as research objects, this paper analysed the etffect of climate warming on the development,generation reproduction, overwintering and migration flight of the pests.The analysis results indicated that the climate warming and increase of accumulated temperature would make the insect pests not only quicken their generation reproduction, but also move their overwintering line northwards and expand their migration flight circle.So that the climate warming would prolong the pest infestation time and cause the harmfulness more severe.

Key words: Climate change, Greenhouse effects Armyworm, Rice planthopper, Reproduction, Migration Flight
