The behavioral responses of Plutella xylostella (Lepidoptera: Plutellidae) to four high power light emmitting diodes (HPLEDs) were tested at various illuminance intensity and light exposure time using a HPLED-equipped Y-maze chamber. Preference tests were conducted using the high power light emmitting diodes (HPLEDs) in the dark room at 27±0.5℃ and 60±0.5% relative humidity. Evaluated specific wavelengths were blue, green, yellow and red HPLEDs. The illuminance intensity was tested at 20, 40, 60, 80, and 100 lx and fixed at 30 min. As a result, the attraction rate of the green HPLED at 60 lx was the best effective (98.3%) to P. xylostella, followed by red HPLED of 60 lx (86.5%), yellow HPLED of 60 lx (83.6%), and blue HPLED of 40 lx (72.0%), respectively. Depending on the change of light exposure time (5, 10, 15, 20, and 25 min), green HPLED showed the potential attraction under the 15 min. These results may be used as information for developing an eco-friendly insect pest control system. Further research needs to be performed to evaluate the behavioral responses to single and multiple HPLED sources in the field.
