Abstract:       The phototactic responses of beetles to different LED lights were studied. Holotrichia titanis Reitter, H. plumbea Hope and Anomala corpulenta Motschulsky showed strong, positive, phototactic response rates of 68%, 84% and 90% respectively, higher than those of H. oblita Hope and H. parallela Motschulsky. Phototactic responses of H. plumbea were slightly influenced by wavelength. A.corpulenta, H. oblita and H. parallela prefered monochromatic lights with peak wavelengths of 405 nm and 465 nm. Male and female H. titanis, H. plumbea and A. corpulenta showed identical phototacitc behavior. However, the phototactic responses of female H. oblita and H. parallela were stronger than those of the males of these species.
