我国研究飞蝗、粘虫、褐稻虱、白背飞虱、稻纵卷叶螟、小地老虎、草地螟等迁飞规律的结果表明,远距离迁飞性昆虫的共同特征是:越冬区域有局限性,虫量大范围同期突增突减,特定世代成虫有生殖滞育过程,上下世代发生期发生量异地衔接,空中或海域可以探测或观察到有规律的虫群迁移和可在预定区段异地标放回收等。根据这些特征可判定昆虫的虫源性质。 The results of the migration rules of Locusta migratoria, Armyworm, Brown planthopper, Sogatella furcifera, Cnaphalocrocis medinalis, Sogatella furcifera and Meadowfoil show that the common characteristics of long-distance migratory insects are as follows: There are some limitations. The abrupt increase of pests in a large area during the same period is abrupt, and the reproductive diapause process of specific generations of adults occurs. The occurrence of offspring of the next generation in different places converges in different places, and the regular migration of insects and swarms can be detected or observed in the air or sea. Section placed in different places, such as recycling. According to these characteristics can determine the nature of insect insects.
