다국어 초록 (Multilingual Abstract)

Plant factories need to develop preventive and control technology of pest infestation as the rapid damage of crops and the occurrence of secondary diseases are major concerns when insect pests are infested with temperature and humidity suitable for growing pests, while creating and maintaining the optimum environment for crop growth. Although a self-contained insect repellent has been developed for the physical control of insect pests, it has not been put into practical use due to the high installation cost compared to the control effect. Therefore, it is necessary to insect pest infestation and physical control technology suitable for the natural light plant and greenhouse environment. In this study, a pest fluorescent response test was carried out for pest catching and development.
For the pest color test, a test apparatus was construct on the test of the agricultural engineering department in Jeonju and tested at intervals of 1 m. The test equipment was 50 x 50 x 50 cm and made of plywood. The inside of the box and the grid pattern were painted with the same color fluorescent material. Fluorescent colors were green, yellow, blue, orange, and red. The test was conducted twice a day at 8:00 am and 5:00 pm. Sugar, rice wine, apple peel and grapes were put into each test device for pest induction. The insect trapping system (SKY-M LED, IRREGREEN Co., Ltd.) was used, and 20W of black light fluorescent lamp was used. Ultrasonic pest control (Ultrasound Ultrasonic Pest Control, Tae Yang Ind. Co.) was used for the pest cotrol. The test period was 35 days from October 19th to November 22, 2017. The pests collected as a result of the test are moth moth, tobacco moth, room moth, thistle moth, other moths, bumblebees, cymbals, pteridophyte, mycetophyll, housefly, etc. 51.53% of mycetophylls, 22.86% of houseflies and 8.92% of caldrus. The moths were 2.03% of the room moths, 1.34% of the moth moths and 0.43% of the tobacco moths. Pests appeared more often in the morning than in the afternoon. In other words, there were many catches at night, and there were various kinds. Blue and red fluorescence showed the highest insect pests, and orange was the lowst insect pests. It was not known whether the insect infusion would be reduced when running the insect repellent only on a test device with UV, etc. However, overall insect repellent activities reduced insect infestation. It was necessary to determine the color of the insect screen along with the physical insect screening at the natural light plant through the insect infestation and eradication system. It has to confirm the necessity of continuously research on the insect pest control at the plant factory.
