| Research Abstract |
We investigate the differences in phototactic behavior between pseudergates and alates. We also determined the spectral sensitivity of compound eyes based on electroretinogram (ERG) to clarify the relationship between the behavior and visual function. With decreasing the wavelength, negative phototaxis was found in the pseudergates, whereas, positive phototaxis was observed in the alates, and the tendency was remarkable at the UV irradiation. The spectral sensitivity of both pseudergates and alates of Zootermopsis nevadensis had the peaks at 360 nm (UV) and 520 nm (green), but the relative intensity was different（pseudergates : 360 nm＜520 nm, alates: 360 nm ＞520 nm）.
