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:

Greenhouse effects Armyworm, Rice planthopper,
