Phototactic behavior: Repellent effects of cigarette beetle, Lasioderma serricorne (Coleoptera: Anobiidae), to light-emitting diodes

Abstract

Repellent effects of specific light wavelengths against the cigarette beetle were evaluated in blue (470 nm), green (520 nm), yellow (590 nm), and red (625 nm) light-emitting diodes (LEDs). Under optimal light conditions (100 lx luminance intensity, 2 h light exposure time), the blue LED (59%) was the most repellent to Lasioderma serricorne adults, followed by green (34.3%), yellow (31.3%), and red (29.3%) LEDs. Moreover, the blue LED was approximately 1.3 times more repellent to L. serricorne adults than a luring lamp black light (BL), 45.7%. These results suggest that blue LEDs could be used for environmentally friendly insect control. © 2013 The Korean Society for Applied Biological Chemistry.
