【摘要】 对蝗总科(Acridoidea)斑腿蝗科(Catantopidae)短星翅蝗(Calliptamus abbreviatus)的染色体C带核型进行了研究,同时与该科两个常见种中华稻蝗(Oxya chinensis)和山稻蝗(Oxya agavisa)的染色体C带核型进行了比较分析。染色体制片采用压片法,BSG法C带处理。结果表明,短星翅蝗、中华稻蝗和山稻蝗在染色体核型方面的差异较小,而在C带方面则显示出一定的差别。短星翅蝗染色体着丝粒区及端部因含有大量结构异染色质而被染色,L2染色体上的C带位置不同和M8染色体上的C带强弱不同,是该物种C带核型与中华稻蝗、山稻蝗相区别的主要特征更多还原

【Abstract】 In this paper, chromosomal C-banding karyotype of Calliptamus abbreviatus was analyzed using chromosomal banding technique induced by the BSG method. Meanwhile, the karyotype was compared with another two Oxya species: O.chinensis and O. agavisa. The result shows chromosomal complement of Calliptamus abbreviatus includes 23 chromosomes and there are obvious C-bands on chromosomes, especially centromere C-bands and terminal C-bands, which are consistent with O. chinensis and O . agavisa . Although the three species have the similar patterns in the main marked chromosomes, there are still a few differences in the detailed C-banding structure. The main features of C. abbreviatus are the different locations of C-bands on L2 chromosomes and the different strong and weak C-bands on M8 chromosomes更多还原
