Study of the photosensitivity of the compound eyes of Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae) alates
Formosan Entomologist 24 (2), 129-136
Abstract: The electrophysiological characteristics of the compound eyes of Coptotermes formosanus Shiraki alates, stimulated by six LEDs, were investigated using electroretinograms (ERGs). The ERGs were negative and monophasic waveforms. The relative spectral sensitivity significantly different in descending order to UV (wave range, 350~425 nm; wave peak, 370.75 nm), blue (367~583 nm; 434.4 nm), green (525~648 nm; 568.3 nm) and red (600~733 nm; 648 nm) light. When UV and blue light were filtered, their light intensities became weaker, resulting in a weaker spectral sensitivity. The Formosan subterranean termite was not sensitive to yellow, orange, or red light. Furthermore, there was no significant difference in the spectral sensitivities between males and females.
