Impacts of Climate Warming on Crop Diseases and Pests in China
Based on the previous research, the existing facts of the temporal-spatial variation of crop diseases and pests in response to the climate wanning in crop growing season, the regularities and the development tendency of crop diseases and pests were systematically analyzed and summarized Then updated the understandings of impacts of climate wanning on crop diseases and pests are put forward and future research trends were suggested. For most crop diseases and pests, climate warming in crop growing season could shorten the development duration, lengthen the damage period, accelerate the development of population growth, increase one more breeding generation than normal, make the occurrence boundary move northward, elevate the limit of altitude, expand the geographic range and significantly aggravate the severity. By contrast, climate warming in growing season diminished the quantity of some high temperature sensitive pests and pathogens, resulting in the migration of wheat stripe rust and aphid from low-altitude areas to high-altitude areas. Generally speaking, climate change in the future would expand the geographic range and aggravate the severity of most of the crop diseases and pests. Diagnostic analysis of the impacts of the climate wanning on crop diseases and pests, impacts projection of occurrence and catastrophe, risk assessment and adaptive strategies are the key issues needed to be solved in the future.
