中文摘要 | 以不同的單色光及光強度刺激基徵草蛉的複眼,觀察其ERG反應的變化。草蛉經過30分鐘的暗適應後,以300 nm至700 nm每隔10 nm的光波刺激右複眼前額區域,每隔6秒鐘刺激一次,每次刺激時間是300ms,經4次之反應平均加算後記錄其ERG。草蛉的ERG為雙相波。計算所得之光譜感光曲線在350 nm(λ max 350nm)處有一高峰,它與Dartnall 350nm 之標準色素曲線極為吻合。複眼以350 nm的光波適應一小時後,其λ max有明顯的被抑制,但其他部份未有變化。 |
英文摘要 | The characteristics of the compound eye of the green lacewing (Mallada basalis Walker) were investigated by recording the electroretinograms (ERG) responding to the illumination of various monochromatic light intensities. The frontal region of the right compound eye was stimulated by a flashing light, ranging from 300nm to 700nm, with an interval of 6 sec after 30-min adaptation in a dark environment. The ERG observed shows a biphasical deflection. The spectral sensitivity curve computed by the ERG response displays a peak activity at UV light (λmax 350nm). The peak activity was substantially suppressed after adaptation in a light environment (350nm) for 1 h. Our present result strongly suggests that the compound eye of M. basalis is very sensitive to UV light. |
