中文摘要：观察了同翅目头喙亚目12种沫蝉雄性的染色体数目和减数分裂行为。通过对沫蝉总科现有核型资料的分析, 认为沫蝉总科的核型特点是: ①染色体较小, 数目较多, 总科内染色体数目变化范围较大, 众数为2n=26 (24+XO); ②染色体的易位现象极为普遍, 因此可以推测, 通过染色体的易位导致染色体数目增加是核型进化的主要机制; ③减数分裂前期Ⅰ具有典型的花束期, 但没有弥散期。因此从精子发生来看沫蝉总科与叶蝉总科、角蝉总科和蝉总科的关系更为密切, 而与蜡蝉总科的关系较远。头喙亚目的亲缘关系可能是: 蜡蝉总科+ {蝉总科+ [沫蝉总科+ (叶蝉总科+角蝉总科)] }。

外文摘要：Meioses in twelve species of Chinese spittle bugs were studied. The results indicated that their chromosome numbers are varied from 2n=16 to 30, and sex determination are all XO type. Karyotype characteristics of Cercopoidea are that: (1) Chromosome volumes are small, chromosome numbers are much varied, most species have higher chromosome numbers, and the predominant type is 2n=26(24+XO). (2) Translocation occurs very frequently. Fragmentation induced by translocation to increase chromosome numbers may be the main mechanism of karyotype evolution in this superfamily. (3) Prophase Ⅰ during meiosis has typical bouquet stage but without diffuse stage, similar to Cicadelloidea, Membracoidea and Cicadoidea, but different from Fulgoroidea. The relationship of superfamilies in Auchenorrhyncha may be Fulgoroidea +{Cicadoidea+[Cercopoidea+(Cicadelloidea+Membracoidea)] }.
