Abstract

[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.
