In order to reduce the amount of chemicals applied in pest control, it is necessary to determine a suitable period for the application. A counting system for the emergence of pests was developed which involves less human labor. The target pest was the diamondback moth (Plutella xylostella (L.)). The plasticated pheromone was used as the attractant and a basin was used for the trap in this system. A digital camera, controlled by the timer function of a computer, automatically took images of the trapped pests. The images were transferred to the host computer using the wireless LAN system. The diamondback moths were segmented and counted using an HSI transform of the image processing technique. This technique was able to show the correct separation with an accuracy of 91%.
