[Method] Ec- onometric models were established to explore the impacts of climate change on the occurrence degree of cotton aphids based on the observation data from 50 counties in Huang-Huai-Hai and Yangtze River basins in 1991-2010, including variables on the occurrence degree of cotton aphids, temperature and precipitation, and other factors. [Result] There were significant differences in the effects of temperature and precipitation changes on the occurrence degrees of cotton aphid in different growth stages, and even in the same growth stage, the cotton aphids had different responses to the changes of temperature and precipitation in different re- gions. [Conclusion] It should give full consideration to the climatic conditions in dif- ferent periods of different regions, and it should adopt proper measures to control the cotton aphids on the basis of figuring out the occurrence rule of cotton aphid, so as to ensure cotton production.展开更多
