摘　　要：[目的]研究红缘短鼻蝗的染色体C带核型。[方法]利用BSG法进行显带处理,显微摄影后,测量染色体和C带带纹的相对长度,计算每条染色体异染色质的含量。[结果]红缘短鼻蝗的染色体组成为2n♂=19,性别决定机制是XO型,染色体全部为端着丝粒染色体,且仅具有着丝粒C带带纹。此外,异染色质在染色体组中的总含量为16.40%。[结论]该研究为癞蝗的细胞遗传学和细胞分类学提供了染色体及其显带方面的资料。[Objective] The research aimed to the chromosomal C banding karyotype of Filchnerella rubimargina.[Method] BSG method was used to carry out the banding treatment.After the micrography,the relative lengths of chromosome and C banding were measured,and the content of heterochromatin in each chromosome was counted.[Result] The chromosome composition of Filchnerella rubimargina was 2n ♂=19,and the sex decision mechanism was XO type.The total chromosomes were the telocentric one and only had the centromeric C banding.In addition,the total content of heterochromatin in the genome was 16.40%.[Conclusion] The research provided the data about the chromosome and banding for the cytogenics and cytotaxonomy of Pamphagidae.
