视网膜电图 [ERG] 和受体细胞的细胞内电位是从 A. macaroIllus 的分开的眼睛中记录的。在用等量子（从315到625 nm）的单色光刺激后确定相对光谱效率和灵敏度曲线。在 ERG 测量中，眼睛的两个部分在 350 ± 20 nm 的光谱 UV 区域中显示出相同的最大光谱灵敏度；然而，在侧眼中，在 530±10 nm 处又建立了一个第二灵敏度峰值。侧眼对绿光 (530 nm) 的敏感度约为 3 50 nm 最大敏感度的 1%。眼睛的额叶部分实际上对 500 nm 以上的波长不敏感。在前眼中，测量了 5 个网状细胞的光谱效率，而在侧眼中，仅测量了 1 个细胞的光谱效率。在所有 6 个单元中，最大灵敏度在于紫外线。在 507 nm 的光刺激下，侧眼的一个细胞也可以记录到更大的反应；尚未测量该电池在整个频谱中的频谱效率。将由此确定的马卡龙眼睛能力与其他节肢动物的已知数据进行比较。讨论了这种选择性紫外线受体的生物学意义。
The electroretinograms [ERG] and the intracellular potentials of receptor cells have been recorded from the divided eyes of A. macaroIllus. The relative spectral efficiency and sensitivity curves were determined after a stimulation with monochromatic lights of equal quanta (from 315 to 625 nm). In ERG-measurements both parts of eyes show the same maximum of the spectral sensitivity in the UV-region of the spectrum at 350 [plus or minus] 20 nm; in the lateral eye, however, one more secondary peak of sensitivity was established at 530 [plus or minus] 10 nm. The sensitivity of the lateral eye for the green light (530 nm) is approximately 1% of the maximal sensitivity at 3 50 nm. The frontal part of the eye is practically insensitive for wavelengths above 500 nm. In the frontal eye the spectral efficiency was measured for 5 retinular cells, and in the lateral eye for one cell only. In all 6 cells the maximum of the sensitivity lies in the UV. Greater responses could also be registered in one cell of the lateral eye with the light stimulation of 507 nm; the spectral efficiency for this cell through the whole spectrum has not been measured. The abilities thus determined for the eyes of the A. macaronius were compared with the data known for other arthropods. The biological significance of such selective UV-receptors are discussed.
