贵州两种黄脊蝗核型和C-带的比较研究

Abstract

Abstract: The karyotypes and C-banding patterns of Patanga japonica Boliver and P. succincta Johansson were investigated. The result showed that the chromosome number of both species are 2n(♂)= 22+X。= 23, and they are all terminal chromosomes. The karyotype formulae are 2n(♂)=2X=23t and NF=23. The total absolute length of Patanga japonica (79.75±2.22)μm exceeds that of P. Succincra (71.47±0.63)μm; and the total amount of heterochromatin of Patanga japonica (35.65%) is more abundant than that of P. succincta (18.70%). The Patanga daponica's karyotype belongs to "IB', and the Patanga succincta's belongs to "Lc".

Key words: Patanga, karyotype, C-banding
