Abstract

Chromosomal polymorphism has been studied in 31 natural populations of Ch.borokensis. For 11 out of 31 populations quantitative analysis of chromosomal polymorphism has been performed. Data from previous publications (10 populations) have also been used to perform an overview of the chromosomal polymorphism of Ch.borokensis and to establish the species range. Most studied populations show a high level of chromosomal polymorphism: on average 66.1 ± 2.6% of specimens were heterozygotes with 1.1 ± 0.6 heterozygotic inversions per larvae. The number of banding sequences found in populations varied from 7 to 18 per population with an average of 12 ± 3. Inversions were found in all chromosomal arms. Besides inversions, B-chromosome was present in 13 populations, and 5 translocations were found. The total number of banding sequences found in banding sequence pool of Ch.borokensis is 40. Twenty six banding sequences are described for the first time for the species.

Chironomusborokensis Kerkis, Filippova, Shobanov, Gunderina et Kiknadze, 1988（双翅目，Chironomusborokensis科）自然居群的Chromosomal多态性。

对31个自然居群的染色体多态性进行了研究。对31个群体中的11个群体进行了染色体多态性定量分析。从以前的出版物（10个种群）的数据也被用来执行的染色体多态性的概述，并建立物种范围。大多数研究群体显示出高水平的染色体多态性：平均66.1±2.6%的标本为杂合子，每只幼虫有1.1±0.6个杂合子反转。在种群中发现的带性序列数为7 ~ 18个，平均为12±3个。在所有染色体臂中均发现反转。除倒位外，13个群体存在b染色体，并发现5个易位。在白桦带序列池中发现的带序列总数为40个。其中26条条带序列为首次发现。
