记录了雄性杂色夜蛾暗适应和色调适应复眼的背部ERG。还有.女性。在光谱范围为320-700 nm的不同波长下，刺激强度的变化超过4.5个对数单位。白光刺激诱发的ERG是一种典型的暗视眼负向单相波。在短波长(近紫外光和紫色光)和长波长(绿-黄)，色刺激诱发的ERG具有不同的波形特征。不同刺激波长的强度-反应曲线的斜率对于相位反应是相似的，而对于ERG的平台成分是不同的。在暗适应和色调适应条件下获得的光谱灵敏度曲线在近紫外峰(最大吸收波长380 nm)和绿色吸收峰(最大吸收波长550 nm)处出现峰值，这表明在杂色云芝复眼的背部至少存在两种受体类型。绿峰(550 Nm)与物种生物发光发射峰(552 Nm)相对应。
ERG [electroretinograms] were recorded from the dorsal sector of dark- and chromatic-adapted compound eyes in the dark-active firefly P. versicolor .male. and .female. at different wavelengths across the spectrum ranging from 320-700 nm over 4.5 log units of change in the stimulus intensity. ERG elicited by white light stimulus was an on-negative monophasic wave typical of scotopic eyes. ERG elicited by chromatic stimuli differed in their waveform characteristics in the short (near-UV and violet) and long (green-yellow) wavelengths. The slope of the intensity-response curves at different stimulus wavelengths were similar for phasic response and differed for the plateau component of the ERG. The spectral sensitivity curves obtained under dark- and chromatic-adapted conditions revealed peaks in the near UV (.lambda.max, 380 nm) and in the green (.lambda.max 550 nm), suggesting the presence of at least 2 receptor types in the dorsal sector of the compound eyes of P. versicolor. The green (550 nm) peak corresponds with the species bioluminescence emission peak (552 nm).
