Abstract
Phototactic responses of Sitotroga cerealella adults to six light emitting diode (LED) monochromatic lights were investigated, and their responses were compared to that using a luring lamp (BLB). Based on the attraction rate under optimal light conditions, UV LED (365 nm) showed the highest attraction rate (67.7%), followed by blue LED (470±10 nm, 57.7%), green LED (520±5 nm, 44.0%), yellow LED (590±5 nm, 20.3%), red LED (625±10 nm, 18.7%), and infrared LED (730 nm, 11.3%). Moreover, the UV LED was 1.2 times more attractive to S. cerealella adults than that of the BLB (58.0%). These results suggest that UV LED could be more useful for mass trapping and monitoring of S. cerealella adults.
