【摘要】 本文研究了贵州日本黄脊蝗ＰａｔａｎｇａｊａｐｏｎｉｃａＢｏｌｉｖａｒ和印度黄脊蝗Ｐ．ｓｕｃｃｉｎｃｔａＪｏｈａｎｓｓｏｎ的核型和Ｃ－带。结果表明：两种黄脊煌的染色体数目均为２ｎ＝２２＋Ｘ０＝２３，全部为端着丝粒染色体；核型公式２ｎ＝２Ｘ＝２３ｔ，ＮＰ＝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（７１．４７±０．６３μｍ）长；异染色质总量《３５．６５±０．１４μｍ）比印度黄脊蝗的（１８．７６±０．１１μｍ）多；日本黄脊蝗的核型属“ＩＢ＂核型，印度黄脊蝗的核型属“ＩＣ”核型。更多还原

【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 + Xo = 23, and they are all terminal chromosomes. The karyotype formulae are 2n = 2X = 23t and NP = 23. The total absolute length of Patanga japonica (79.75 ±2.22)μm exceeds that of P. tuccincta (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 Jqponica’s karyotype belongs to "IB", and the Patanga tuccincta’t belongs to "IC".更多还原
