| 摘 要： | 本首次研究了采于中国的辉蝽属三个种一辉蝽（Carbula obtusangula Reuter)、北方辉蝽（Carbula putoni(Jakovlev)，凹肩辉蝽（Carbula sinica Hsiao et Cheng)的核型，结果表明，三个种均具有典型的蝽科核型即：2n(♂）＝14，具有XY性别决定机制，但是三个种的常染色体和性染色体在减数分裂时期的行为以及核型分析的结果和模式图各不相同，而且在北方辉蝽中出现了1－2条超数染色体，这些特点可为辉蝽属昆虫的形态分类及系统发育提供有用的证据。

| Abstract: | The karyotypes and meiotic behaviors of three Carbula species( Carbula obtusangula Reuter, C.putoni (Jakovlev)and C. sinica Hsiao et Cheng)were studied.Karyotype analyses using specific software were made and model karyotype chart was presented.All three species have the typical diploid chromosome number of 14 for the family Pentatomidae and X Y sex chromosomal mechanism,but the behavior of autosomes and sex chromosomes during meiosis among three species are different,and one or two supernumerary chromosomes were detected in C.putoni. These characteristics may provide some useful clues on the study of pentatomid taxonomy and phylogeny. |
