摘要: 本文研究了贵州日本黄脊蝗 Patanga japonica Bolivar和印度黄脊蝗 P.Succincta Johansson的核型和c-带。结果表明:两种黄脊蝗的染色体数目均为2n()=22+x.=23,全部为端着丝粒染色体;核型公式2n(♂)=2X=231,NF=23. 但日本黄脊蝗的染色体绝对长度总和(79.75±2.22μm)比印度黄脊蝗的(71.4 7±0.63μm)长;异染色质总量(35.65±0.14μm)比印度黄脊蝗的(10.76±0.11μm多;日本黄脊蝗的核型属“1B”核型,印度黄脊蜱的核型属“lc”核型。

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".
