我国地处东亚季风区域。褐稻虱长距离北迁南回现象是东亚大气低层环流季节性变化引起的。本文根据全国褐稻虱科研协作有关单位的试验观察报告,对照气象资料,就我国褐稻虱迁飞高度、迁飞方向、降落条件和起飞虫源等问题进行初步分析,作出我国褐稻虱迁飞路径图以供参考。
My country is located in the East Asian monsoon region. The long-distance north migration of BPH is caused by the seasonal changes of the low-level circulation in the East Asia. Based on the experimental observation reports of relevant units of the brown planthopper scientific research cooperation in our country and the comparison with the meteorological data and the preliminary analysis of the problems such as the flight altitude, the direction of migration, the landing conditions and the origin of the brown planthopper in China, Fly the road map for reference.
