We investigated the fluorescence of silkworm cocoons under ultraviolet light, a feature which has attracted little attention till now. Evaluating the intensity of fluorescence with Scion Image software, we expressed the highest intensity as 100, and rated the intensities of fluorescence of 111 silkworm races. Different races showed different strengths and weaknesses of intensity. Arranging the intensities step by step, we found that differences in the color and intensity of fluorescence influenced the spectrum curve. ( E mail :
