Orientation of Callosobruchus chinensis (L.) towards seven coloured light emitting diodes was observed under three conditions at different time intervals. In multi-choice test, C. chinensis adults were more attracted towards green (13.13 to 13.80%), blue (12.13 to 13.73%) and ultraviolet (13.20 to 14.20%) LEDs which have shorter wavelengths and high frequencies, while white (control) (7.20 to 9.67%) and red (6.13 to 8.40%) LEDs having longer wavelengths and low frequencies showed the least preference.
