白星花金龟成虫两种体色反射光谱的差异性分析

The difference of spectral reflectance between two different body colors of the adult Protaetia brevitarsis Lewis,Scarabaeidae

利用光谱检测系统测量白星花金龟Protaetia brevitarsis Lewis成虫两种体色个体不同部位的反射光谱,发现白星花金龟青铜色和古铜色个体4个测量点都反射紫外光(300~400 nm)和人类可见光(400~700 nm).古铜色个体光谱反射率整体低于青铜色个体,且青铜色个体反射波峰较古铜色个体多黄绿光反射峰.通过SPSS统计软件主成分分析比较,两种体色测量点反射光谱的主成分(明度、色度、饱和度)得分总体是有极显著差异的.比较发现,白星花金龟成虫青铜色个体的体色较古铜色个体更明亮更绚丽更多彩.

In this paper,the reflectance spectra of Protaetia brevitarsis Lewis adults in different parts of two body colors were measured by using a spectral detection system.It was found that the four detection points of bronze and purple-bronze individuals reflected ultraviolet light(300~400 nm)and human visible light(400-700 nm).The contrast of light and shade of the overall color spots of purple-bronze individuals is lower than that of bronze individuals,but the reflectivity waveform of bronze individuals is more yellow green reflection peak than that of purple-bronze individuals.Through the principal component analysis of SPSS statistical software,the main component scores(Brightness,Hue,Chroma)of the two body color test points are significantly different.It is found that the individual color of bronze is more bright,gorgeous and colorful than purple-bronze individual.
