We made an insect trap for automatic monitoring by combining a commercially available IoT monitoring camera with a sticky pheromone trap to determine the number of daily trap catches of insect pests in real time. The IoT camera automatically takes a picture of the sticky board capturing insect pests every morning and then immediately sends the image to a designated e-mail address. The present study verified whether the IoT camera-equipped sticky pheromone trap is useful for monitoring the daily occurrence of Spodoptera exigua (Hübner) in a commercial chrysanthemum field in Osaka Prefecture. The number of trapped males, counted by viewing the e-mailed images of the sticky boards on the monitor screen of a personal computer, almost coincided with that counted by directly checking the same sticky boards that were collected at an interval of 14–27 days: the count via images was –4 to 1 more than the in-person counts (–5.6% to 1.9% of the in-person counts). The numbers of males peaked on July 14, August 9, September 4, and October 13. These results indicate that the IoT camera-equipped sticky pheromone trap is helpful for determining the daily catches of S. exigua males in commercial fields.
