本文主要以水稻害虫区系十分丰富的亚洲为例,从水稻害虫的区系、变化近况,与生产体糸变化相关的害虫预测及其展望等方面来阐明近年来,单食性、一化性、驻留型害虫种群趋于衰落,而杂食性、多化性、迁飞型害虫种群趋于增长的发展趋势。害虫种群的治理最终将通过选择性杀虫剂、抗性品种、栽培措施等手段的综合应用来解决。 In this paper, we mainly take Asia, where pests of rice are very rich, as an example. From the perspectives of the pest population, current status of pests, pest prediction related to production changes and their prospects, The resident pest population tended to decline, while the omnivorous, diversified and migratory pest populations tended to grow. The management of pest populations will eventually be resolved through the integrated application of selective insecticides, resistant varieties, cultivation measures and other means.
