摘　　要：对分布在广西的负蝗属AtractomrophaSaussure2个种奇异负蝗AtractomrophaperrgrinaBietxia和纺梭负蝗AtractomrophaburriBolivar的核型和C带带型进行分析研究.结果表明:在染色体组式、性染色体、异染色质含量和除着丝粒C带以外的其他C带分布类型方面都有明显差异;但在染色体数目、性别决定机制、染色体着丝粒类型和着丝粒C带等方面有相同的特征.The C-banding karyotypes of Atractomropha perrgrina Bi et xia and Atractomropha burri Bolivar in Atractomropha Saussure in Guangxi were studied.According to the result of the test,there was (obvious) differences in genome formula,sex chromosome,amount of herterochromatin,intercalary and telomere band;but there was the same character in chromosome number,sex determination,telocentric chromosome and centromeric band.
