摘  要:
对采自吉林省松花湖库区的黄褐油葫芦Teleogryllus derelictus的染色体C-带核型进行了分析。结果表明:黄褐油葫芦的染色体数目为2n(♂)=26+XO=27,其中有7对为中部着丝粒染色体,其余为端部着丝粒染色体;染色体组式为2L+7M+4S+X;属"1B"核型;染色体都含有着丝粒带,其中L1~M7及X染色体各具一弱染端带。同时我们也将其与黄脸油葫芦进行了比较分析。

摘  要:
The chromosomal C-banding karyotype of Teleogryllus derelictus,collected from Songhua lake of Jilin province,was analyzed.The chromosomal number of this species is 2n(♂)=26+ XO=27,with the basic Orthopteran sex determining mechanism XX♀/XO♂,in which seven pairs are metacentrric chromosomes and the others are telocentric.All the chromosomes possess centeomere C-bandings and only L1—M7 and X chromosomes have terminal bandings.The genome formula is 2L+7M+4S+X.The comparative analyses between Teleogryllus derelictus and T.emma are also reported.
