| Abstract: | The karyotype of Locusta migratoria migratoria （L.） in Jilin Province was analyzed by conventional chromosome analysis.The sex-determining mechanism of Locusta migratoria migratoria was XO and the chromosome number was 2n♂=23 with a karyotype formula of 4L＋4M＋3S＋X.All chromosomes were telocentric,NF=23 of the ＂1C＂ type.There was no obvious evidence of a B chromosome and satellite.A comparative study of the karyotypes of Locusta migratoria migratoria in Jilin and Xinjiang Provinces indicates that they belong to two different geographic populations of the same subspecies that have distinct geographical environments.Slight differences in chromosomal karyotype were apparent between the two populations. |
