摘要

本試驗係針對有翅型家白蟻複眼對於六種發光二極體的感光性，由視覺電生理的角度，探討與趨光行為之相關性。所測得的複眼網膜電圖（ERG）均為負單相波型（negative and monophasic waveform），其振幅由大至小依次為：紫外線（波長範圍350～425 nm，波峰370.75 nm）、藍光（367～583 nm，434.4 nm）、綠光（525～648 nm，568.3 nm）、紅光（600～733 nm，648 nm），且相對感光性有顯著差異，雌雄個體之間並無差異；當光強度愈弱，所測得ERG振幅就愈小。

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.
