The cytotaxonomic characteristics of two species of the Chironomus genus from Lake Łuknajno (northwest Poland) were determined: Chironomus nuditarsis Strenzke, 1959 with the chromosome arm combinations of AB, CD, EF, and G (the "thummi" cytocomplex), and Camptochironomus tentans (Fabricius, 1805) with the chromosome arm combinations of AB, CF, DE, and G. A heterozygous inversion in arm F of the Chironomus nuditarsis chromosomes was detected. The polymorphism of Camptochironomus tentans as a homozygous inversion in arms A and E and a heterozygous inversion in arm F were revealed.

The pupa and imago of Chironomus acerbiphilus (a senior synonym of C. crassimanus) show wide variation of external morphology characters. This paper describes the external morphology of larva, pupa and adult of C. acerbiphilus from Poland. Variability of morphological characters is evaluated for the Polish population in comparison with other European, Asian and North American populations. Pupal suhgeneric characters are discussed.

The effects of pollution on the biodiversity and genome response of Chironomidae larvae (Diptera, Insect) were evaluated in the trace metal contaminated water environments. No change on the Chironomid species diversity was found. The higher concentrations of trace metals (Cd, Pb, Cr, and Zn) affect the genome of 5 cytogenetically studied Chironomid species: Chironomus bernensis, C. plumosus, C. sp.1. Kiefferulus tendipediformis (cytotype 2), Glyptotendipes cauliginellus (syn. Glyptotendipes gripekoveni). Genome instability of Chironomid larvae was manifested by two ways: 1. Fixed chromosome rearrangements; homozygous inversions and tandem fusions created new gene linkage groups and show an intensive microevolutionary process of species. 2. Somatic structural (inversions, deficiencies, deletions, breaks); and functional alterations (decreasing the activity of the key structures: Balbiani rings (BRs) and Nucleolar Organizer (NOR)) in salivary gland chromosomes of cytogenetically studied Chironomidae species. Detecting somatic rearrangements in salivary gland chromosomes of these widely distributed aquatic insects is potentially one of the best validated bioassay and can be used as a cost effective early warning signals of environmental damage in freshwater basins.

Chironomus melanotus Keyl, a new species of Polish fauna, is described on the basis of cytogenetic characteristics. It belongs to the cytocomplex thummi with the chromosome set 2n = 8, chromosome arm combinations AB CD EF G and species-specific karyotype markers. Two types (somatic and inherited) of structural chromosome rearrangements in salivary gland chromosomes were identified in the species and somatic rearrangements (heterozygous inversions, deficiencies, deletions — Somatic index — 0.54) were observed for the first time in this species. In addition to those in the mosaic state, some genome alterations — trisomy and “B” chromosome, as well as larval malformations (10.27%) were detected for a first time. The malformations and somatic structural and genome aberrations may have been caused by different stress agents in the environment. Thus, we suggest that the high spectrum of somatic rearrangements observed in C. melanotus may indicate the existence of pollution (elevated Cd and Pb concentrations) in Lake Łuknajno (the study area) and perhaps trace metals and different chemicals produced by the Chara species.

This paper presents the karyotype and external morphology of larva, pupa and adult male of Stictochironomns sticticus (Fabricius, 1781) from Poland. The species of the genus Stictochironomus are generally identified on the basis of pupal and adult morphology. However, the species described in this paper has species-specific markers in the salivary gland chromosomes which allow identification at the larval stage. Karyological markers are evaluated for the Polish population in comparison with other European populations and Stictochironomus species.

This paper reports on studies of the effect of heavy metals on the Chironomidae that inhabit the Matylda stream, which has been contaminated for about 100 years by discharge water from a zinc and lead ore mine. Stream sediment was strongly polluted by Cd, Pb, Cu and Zn. These metals did not affect the Chironomidae community but strongly changed the genome system of the Chironomidae species that inhabited the sediment. The salivary gland chromosomes of six species belonging to the two genera Chironomus and Prodiamesa are analyzed. In all species the somatic index is calculated on the basis of somatic chromosome alterations. Chironomus riparius has the highest numbers of somatic alterations and the highest somatic index — 9.67. The smallest chromosome G carries the key structures known as “Balbiani rings”, which play an important role in species development. This chromosome is very sensitive in the genome of the most studied species. The high sensitivity of the C. riparius genome is discussed in light of its DNA organization. The results show a high response of the salivary gland chromosomes to heavy metal pollution, and this makes them a valuable indicator in the assessment of water quality and detection of mutagenic agents in the aquatic environment.
