【摘要】 以长白山林区21种食蚜蝇为研究对象,测量食蚜蝇的8个形态指标值,利用SPSS软件得到聚类树形图,从而对21种食蚜蝇的亲缘关系进行测定,结果表明:1号至15号属于迷蚜蝇亚科,16号到21号属于食蚜蝇亚科,与传统的形态分类结果一致。数值分类方法简单易行,在昆虫分类中具有一定作用。更多还原

【Abstract】 In this study,we taken 21 species of Syrphid flies as objects in Changbai mountain forest region to measure 8 morphological numerical values. Clustering tree diagram was obtained by SPSS. The results of genetic relationship measurement of 21 species of Syrphid flies showed that: No. 1 to No. 15 were belonged to Milesiinae,NO. 16 to No. 21 were belonged to Syrpinae according with the traditional morphological classification results. Numerical classification method is simple and practicable,it also plays a certain role in insect classification.更多还原
