摘　　要：为对夜蛾翅脉特征进行分类研究,以6种夜蛾右前翅的翅脉为研究对象,利用tpsDig2软件在夜蛾翅室周围翅脉交叉点处提取标记点,利用普氏叠加分析消除标记点数据中的非形状因素信息,计算出相邻翅脉交点间的距离作为特征参数,利用方差分析和逐步判别分析论证各项特征参数对6种夜蛾进行分类的可行性、可靠性和重要性。研究结果表明:7个特征参数可作为分类变量,它们的作用大小依次为:(dis67、dis71)>dis34>(dis23、dis12)>(dis45、dis56),原始判别和交叉判别结果的正确率分别为99.4%和99.4%。这充分证明了蛾翅翅脉的特征变量可用于蛾类昆虫的分类鉴定研究。This study was performed on six noctuid species and vein characteristics of the right forewings were adopted to classify moths.Junctions of veins around cell wing from the six noctuid species were selected as landmarks by using software tpsDig2.Procrustes superimposition was applied to remove non-shape variation from the landmark coordinates,and the distance between adjacent vein nodes was calculated as characteristic parameters.And,variance analysis and stepwise discriminant analysis methods were used to study the feasibility,reliability and importance of each characteristic parameter as classification criterions on the six noctuid species.The results showed that seven characters were selected as the classification variables.The contribution of these variables could be ranked as follows：（dis67,dis71）〉dis34 〉（dis23,dis12）〉（dis45,dis56）.Accuracies of original and the intersecting discriminant analysis were 99.4% and 99.4% respectively.The results indicated that vein characteristics of moth wings could be used to identify moths.
