Abstract

The results of long-term studies of biting midges (Diptera, Ceratopogonidae) in macrozoobenthos communities of five saline rivers of the hyperhaline Lake Elton basin are presented. The fauna of Ceratopogonidae includes five halophilic and euryhaline species, among which representatives of the tribe Sphaeromiini predominate. The taxonomic composition of the family differs in rivers with different levels of salinity. Species Sphaeromias miricornis and Culicoides riethi are widely distributed in the mesohaline Khara, Lantsug, and Bolshaya Samoroda rivers, and Palpomyia schmidti is widely distributed in the polyhaline Chernavka and Solyanka rivers. Two generations of S. miricornis and three generations of P. schmidti are recorded. The emergence of the first generation of P. schmidti occurs in mid-May; S. miricornis emerges in late May to early June. There is an increase in the mean annual abundance and biomass of biting midges in polyhaline rivers when compared with mesohaline rivers.

盐河（俄罗斯埃尔顿湖盆地）大型底栖动物群落中叮蠓（双翅目、角蠓科）的耐盐性和季节和多年动态

摘要

本文介绍了高盐度埃尔顿湖盆地五条咸水河流的大型底栖动物群落中的叮蠓（双翅目、角蠓科）的长期研究结果。 Ceratopogonidae 动物群包括五种嗜盐和广盐物种，其中以 Sphaeromiini 部落的代表占主导地位。不同盐度的河流该科的分类组成也不同。物种Sphaeromias miricornis和Culicoides riethi广泛分布于中盐喀拉地区， Lantsug 河和 Bolshaya Samoroda 河，Palpomyia schmidti 广泛分布于多盐 Chernavka 河和 Solyanka 河中。两代S。 miricornis 和三代P。 schmidti 已记录。第一代P的出现。 schmidti 发生在五月中旬； S。 miricornis 出现于五月下旬至六月初。与中盐河流相比，多盐河流中蠓的年平均丰度和生物量有所增加。
