Abstract: To understand the visual responses of the southern green stink bug, Nezara viridula, we investigated the behavioral preference for wavelengths, and also checked the spectral sensitivity of the bug. The compound eyes of N. viridula adults showed a bimodal sensitive pattern to wavelengths (300-740 nm), responding strongly to ultraviolet region (peak at 360 nm), and maximally to green region (peak at 520 nm). In free-flying preference experiments using light-emitting diodes (LEDs) of five different peak wavelengths (373, 444, 464, 534 and 583 nm), both male and female adults strongly preferred the ultraviolet light (373 nm) among five LEDs. Among all other four, adults preferred blue region light (444 nm and 464 nm) to 534 nm and 583 nm. In dual choice experiment, N. viridula choose green light (534 nm) more than orange light (583 nm). These results show that N. viridula prefer shorter wavelength light under the same photon flux density, and indicate the potential use of short wavelength light for light trap to monitor N. viridula.
