摘要

利用網膜電圖（Electroretinogram，ERG）法及視細胞（retinular cell）胞內記錄法（intra-cellular recording method），研究番茄夜蛾（Heliothis armigera）複眼之光譜感光度（spectral sensitivity）。以322nm至701nm光域測番茄夜蛾複眼之光譜感光曲線（spectral sensitivity curve）中，發現有3個最大吸光域（λ max），各為349nm（紫外光部分），491nm（藍色光部分）及559nm（綠色光部分）。胞內記錄法查驗，只發現藍色與綠色感光細胞之存在，而未發現吸收紫外光感光細胞。由以上之事實，可以推論：番茄夜蛾光譜感光曲線中，紫外光部分，實係藍色或綠色感光細胞所誘起的次級反應（secondary response）。

Spectral responses from the compound eye of cotton bollworm Heliothis armigera were investigated electrophysiologically by means of using the ERGs and the intracellular recording methods. The light stimuli covering the range of wavelengths from 322nm to 701 nm had been adopted in the experiments. In ERGs, there are three peaks in their spectral sensitivity curves. These peaks appeared at 349nm (U. V.), 491nm (Blue) and 560nm (Green) respectively, but only two kinds of colour receptor cells (blue and green colours) were identified by intracellular recording method, and the U. V. receptors were not recorded. We assume that the U. V. peak appeared in the ERGs may be originated from the secondary peaks of the blue or green colour receptors.
