【摘要】 全球气候变暖及其影响已引起世界的普遍关注。根据我国气候变化的特点及气候对害虫的影响，本文分析了气候变暖后我国作物害虫发生的趋势，并提出了可能的防治对策。随着气候变暖，作物害虫生长发育速率将加快，年发生世代数可能增加，越冬界线将向北移动，为害将加重。但害虫向北扩展的速度将受到害虫所依赖的寄主作物向北迁移速度的限制更多还原

【Abstract】 Nowdays, global warming and its vital effects on ecosystem have been the main concern of the world. According to the characteristic of climate change and its effects on pests, in this paper, the occurrence trend of crop pests with warming climate in China was analysed and some feasible control strategy of pests was proposed. With warming climate, the pests will grow and develop faster; its generations in one year may increase and its damage may become serious. The overwintering line of pests may move northward but it is restricted in their spreading northward by the distribution of their host crops.更多还原
