摘要: 本文对采自四川峨嵋山的峨嵋哑蟋(Goniogryllus emeicus Wuet Wang 1 992)及四川康定的藏蜀哑蟋(G.potanini B.-Bineko 1956)以及湖北神农架的一种聋蟋(Cophogryllus sp.)的染色体作了比较研究,结果显示,3种无翅类蟋蟀的核型具有一定相似性,核型的差异可能是由于臂间倒位和着丝粒的融合和裂解。同时,对聋蟋的C带核型也作了报道,研究表明,此种聋蟋的异染色质含量为34.15%。
Abstract:In this paper,the chromosome of two species of Goniogryllus (G.eneicus Wu et Wang 1992,G.potanini B.-bienko 1956)one specie of Cophogryllus(C.sp.)have been comparatively studied.According to the results of the research,the karyotypes of three species of wingless crickets have common deriving,the variation is due to centric fusion and rission,and pericentric inversion.Then,the C-banding karyotype of Cophogryllus sp.has been studied.
