摘      要：The fall armyworm(FAW),Spodoptera frugiperda(Lepidoptera:Noctuidae),has invaded many countries in Africa and Asia since 2016,posing a major threat to world food ***-distance migration and strong reproductive ability form the biological basis of its rapid population expansion,but the relationship between the flight and reproduction of FAW has not been studied in ***,an empirical assessment of this relationship in an invasive FAW population in China found that 1-3-day-old adults which had undergone 10-h tethered flights had a significantly shorter pre-oviposition period and greater oviposition synchronization,but did not show any differences in fecundity,oviposition period,mating percentage or other reproductive *** studies on moths after 1.25-15-h tethered flights indicated that the reproductive process of adults could be fully triggered by flight activity longer than 2.5 *** of the reproductive organs also showed that tethered flight promoted ovarian and testicular development of *** results show that appropriate moth flight activity significantly speeds up the reproductive process of FAW,which increases our knowledge on its migratory biology in relation to regional outbreaks.
