Abstract: 【Aim】 The study aims to get the sensitive spectral range of Anomala corpulenta Motschulsky to light.【Methods】 The phototaxis behavior of A. corpulentain response to spectral sensitivity was tested under 14 monochromatic lights ranging from 340 nm to 610 nm in the laboratory. 【Results】 A. corpulenta adults showed phototaxis reaction to all the tested monochromatic wavelengths between 340 nm and 610 nm spectrum, and the phototactic behavior response rates were higher in the monochromatic light UV (405 nm), blue light (460 nm) and green light (505 and 570 nm) in male and female adults. Sexes affected their phototactic behaviour, but only affected the levels of response rate peaks. The spectral photophobic behavior response of A. corpulenta adults showed no significant difference between the two sexes, and the photophobic behavior response rates were higher in the spectrum of ultraviolet region (380 nm), blue light (440 nm) and green light (492 and 505 nm). 【Conclusions】 There are differences in phototaxis of A. corpulenta to light between different wavelengths, and gender is an important factor affecting the spectrum of behavioral responses. The results not only provide a necessary theoretical foundation for further research of light vision in A. corpulenta, but also provide a scientific basis for the use of phototaxis to the integrated management of scarab beetles.
