Abstract: This experiment was conducted in the area of Punjab Agriculture Research Station (PARS) and Chak No.33 JB Faisalabad to evaluate the response insects to varying wavelengths of light. During experiment, lights of six different colors (blue, green, yellow, red, black and white) were tested. All lights were arranged in a line on agriculture land, close to Faisalabad Airport. Tree rows/blocks, forest nursery, fruit garden, wheat, maize and fodder crops were the main vegetative covers in the vicinity. Each selected color light was properly projected on 1 m^2
vertical screen (made of white cotton fabric) placed one meter high above the ground. All lights were kept on simultaneously for half an hour and the insects attracted on both sides of the screens were collected in tubs containing soapy water. At the end of experiment, the collection was shifted to properly labeled storage bottles for counting and identification into respective orders. The
highest number of insects was observed in container placed under black light (ultraviolet light), while the lowest in that of red light. Similarly, the common insect orders frequented among all color lights were Diptera, Coleoptera and
Lepidoptera respectively. The experimental results indicated that insects are attracted in more number on lights with short wavelengths and high frequencies and vice a versa.
