摘  要:
从总科角度对鳞翅目 (Lepidoptera)和鞘翅目 (Coleoptera) 5个总科 2 3种昆虫图像中提取的昆虫面积、周长等 11项数学形态特征进行了统计分析。结果表明 ,在总科阶元上 ,11项特征的可靠性大小为圆形性 >(面积、周长、横轴长、球形性、似圆度、偏心率 ) >(纵轴长、叶状性 ) >(形状参数、亮斑数 )。从数学形态特征角度讲 ,夜蛾总科等 3个总科的亲缘关系远近大小依次为夜蛾总科与凤蝶总科 >蚕蛾总科与凤蝶总科 >夜蛾总科与蚕蛾总科。

摘  要:
Statistical analyses of 11 math-morphological features (MMF) (such as area, perimeter, etc.) from images of 23 species of insects from the Lepidopter a and Coleoptera families Noctuoidea, Bombycoidea, Papilionoidea, Scarabaeoid ea and Chrysomeloidea indicates that the ranked reliability of MMF in the i dentification of insect superfamilies is, from high to low: [BF]circularity>(ar ea, perimeter, X-length, sphericity, roundness, eccentricity)>(Y-length, lob ation)>(form factor, hole number). From the perspective of mathematical mo rphology, the kinship of three superfamilies can be ranked as follows: Noctuoidea & Papili onoidea>Bombycoidea & Papilionoidea>Noctuoidea & Bombycoidea.
