Abstract: In this paper, dynamic change of adult Spodoptera litura in the field were monitored using remote real-time monitoring system to determine intelligent monitoring level including accuracy of automated counting and remote information transmission. The results showed that dynamic shown in the remote monitoring system was coincided with that shown in common monitoring by sex pheromone. It indicated that this system could reflect the occurrence of Spodoptera litura in the field to some extent and meet the technical demands of predication and forecast. This system would provide a new way for intelligent predication and forecast of noctuidae iInsect in Xiamen City.
