Performance Evaluation of Low Attracting Insects between Sunlight Type LEDs, High CRI LEDs and White LEDs

Abstract

The study was conducted to evaluate the insect control performance of sunlight type LEDs, high color rendering index（CRI）LEDs, white LEDs and prototype of LEDs in a comparative laboratory test. Musca domestica（house flies）and Megaseria sclaris（scuttle flies）were used in the study. The number of houseflies captured by high CRI LEDs was significantly higher than that of white LEDs. The number of house flies and scuttle flies captured by sunlight type LEDs was significantly higher than those captured by white LEDs. The number of scuttle flies captured by sunlight type LEDs was significantly higher than that of high CRI LEDs. The number of house flies captured by white LEDs was significantly higher than that of prototype of LEDs. The results of this study show that high CRI LEDs and sunlight type LEDs have higher insect attracting power than white LEDs. On the other hand, prototype of LEDs have lower attractiveness than white LEDs. These results suggest that insect attractiveness is not only influenced by UV light but also by visible light.
