Phototactic behavioral responses of the Indian meal moth, Plodia interpunctella (Hübner), adults were determined to different light-emitting diodes (LEDs) of seven wavelengths, and their behavioral responses were compared to that using a commercial luring lamp (BLB) under laboratory conditions. Based on the attractive responses under optimal light conditions (60 lx luminance intensity and 30 min light exposure time), the green LED (520±5 nm) showed the highest attractive rate (520±5 nm, 52.2%), followed by the blue LED (470±10 nm, 33.9%), the yellow LED (590±5 nm, 32.2%), BLB (28.9%), UV LED (365 nm, 22.8%), the red LED (625±10 nm, 14.5%), the white LED (450-620 nm, 10.6%), and IR LED (730 nm, 9.5%). In addition, the green LED to P. interpunctella adults was approximately 1.81 times more attractive than BLB. These results indicate that the green LED could be most useful for monitoring of P. interpunctella adults.
