摘要
根据四川稻飞虱灯下诱捕资料，结合历史天气图等气象资料，分析四川稻飞虱迁入概况、峰次及其相应的天气形势，得出了四川省稻飞虱迁入发生的天气形势特征和环流分型，为四川水稻用飞虱发生的测报提供了依据。
Based on the information of plant hopper-killing lamp and the data of the historical weatherchart the plant hopper migration to Sichuan Province ,the frequency of swarming and its correspondingweather conditions are studied． The weather situation features and circulation types which plant hopperinvades are obtained ， thus the scientific basis for advanced prediction of the occurrence of plant hopperin Sichuan Province is provided.
