Abstract The long-term impact of pollution in freshwater aquatic environments can be assessed realistically only if the mutagenic effects pollutants on organisms inhabiting biotopes are evaluated. To do this, larvae Chironomids (Diptera) serve as suitable indicators potential environmental genotoxicity. These exhibit aberrations their polytene chromosomes, which, when analyzed, indicate an early response to toxicity more efficiently than morphological analysis, up now usual technique. have...

Abstract The sleeping chironomid ( Polypedilum vanderplanki Hinton) lives on temporary rock pools in the semi‐arid tropical regions of Africa. Its larvae are able to survive dry season a completely desiccated ametabolic state known as anhydrobiosis. So far, P. was only species among all insects showing demonstrated anhydrobiotic ability. Here, we show that new related originating from Malawi, pembai sp.n. , is also and its desiccation tolerance mechanism probably similar what observed ....

Inter- and intracytogenetic variability was analyzed in 13 natural Palearctic populations of Chironomus riparius Meigen 1804 (syn. thummi) by examining hereditary somatic aberrations (mainly inversions) the salivary gland polytene chromosomes. In total, 77 different types inherited inversion sequences 184 inversions were found. The median percent frequency 1.4% karyotypic divergence between very low. Most endemic always a heterozygous state. Only six sequences, each them shared two distant...

Abstract Genotoxic effect as tested of chronic exposure to three different concentrations Chromium (III) on polytene chromosomes larvae Chironomus riparius (syn. thummi) from the embryonic stage IV larval instar for two successive generations. In AB, CD, EF and G significant differences chromosome aberrations were found between exposed control well changes in functional activity (induction novel puffs not corresponding those induced during normal development arms A, B, C E, telomeric...

Abstract The effect of lead (Pb) nitrate on the structural and functional organization polytene chromosomes Chironomus riparius larvae was examined. No specimens with standard were found in material treated different concentrations Pb ions. all individuals exposed to showed various somatic chromosome rearrangements (heterozygous inversions, deletions, duplications deficiencies), which not detected studied controls. Deletions G occurred a high frequency resulting formation so called...

Intra and interspecific variation was evaluated in two Bulgarian populations (Pancharevo Kokalijane) of the sibling homosequential species Chironomus riparius Mg. piger Strenzke, by analyzing structural functional alterations salivary gland polytene chromosomes. In both genome instability demonstrated, which expressed somatic chromosomal alterations. C. population from Pancharevo, living sediments containing high concentrations Cu, Pb Zn, cells romatic rearrangements appeared at a...

Chironomids are a ubiquitous group of aquatic insects that very sensitive to environmental stress. Due the presence polytene (‘giant’) salivary gland chromosomes, it is possible define genome response several Chironomid species various stress agents. The aim this study was assess genotoxic changes in populations widely distributed chironomid from basins Bulgaria, Italy, Russia, U.K. and Poland, which were exposed high concentrations trace metals. We analyzed structural functional alterations...

The African chironomid Polypedilumvanderplanki Hinton, 1951 is the only able to withstand almost complete desiccation in an ametabolic state known as anhydrobiosis. karyotypes of two allopatric populations this anhydrobiotic chironomid, one from Nigeria and another Malawi, were described according polytene giant chromosomes. karyotype Nigerian population was presented reference chromosome map for Polypedilumvanderplanki. Both populations, Malawian, showed same number chromosomes (2n=8), but...
