Karyotypes of Chironomus Meigen (Diptera: Chironomidae) species from Africa
The karyotypes of six African Chironomus species (Chironomus alluaudi Kieffer, 1913, Chironomus transvaalensis Kieffer, 1923, Chironomus sp. Nakuru, Chironomus formosipennis Kieffer, 1908, Chironomus prope pulcher Wiedemann, 1830, Chironomus sp. Kisumu) were investigated; four of these karyotypes were described for the first time (Chironomus sp. Nakuru, Chironomus formosipennis, Chironomus prop...
متن کاملCytogenetic divergence of genomes in Chironomus plumosus group (Diptera: Chironomidae)
The phylogenetic relationships and karyotype differentiation of 14 sibling species of Chironomus plumosus group were studied using comparative analysis of polytene chromosome banding sequences. Revision of banding sequence pools has been made for all species. Main and alternative banding sequences of 6 chromosomal arms (A, B, C, D, E, and F) of each species were used for the analysis. In total ...
متن کاملپرورش انبوه لاروهای (Chironomus riparius (Dip.: Chironomidae
لاروهای آبزی پشه‌ی Chironomus riparius Meigen یکی از منابع غذایی غنی در پرورش ماهیان می‌باشد. کمیت و کیفیت ماده‌ی غذایی که در پرورش این لاروها استفاده می‌شود، بر رشد و نمو دوره‌ی لاروی این پشه تأثیر‌گذار است. این مطالعه شامل بررسی اثر جیره‌های غذایی مختلف (کود مرغی، پودر سویا و سبوس برنج) با مقادیر وزنی متفاوت (1، 3 و 5 گرم) بر رشد و نمو لاروها، تعیین زمان مناسب برداشت لاروها در دماهای مختلف (...
متن کاملSpecies of the subgenus Chaetolabis, townes 1945 of the genus Chironomus, Meigen 1803 (Diptera: Chironomidae), from a cytogenetic perspective.
The polytene chromosomes of three North American species in the subgenus Chaetolabis of the genus Chironomus are described and compared to the published karyotypes of two Palearctic species. Chironomus (Chaetolabis) atroviridis has four polytene chromosomes, like the Palearctic C. globulus, while C. ochreatus and the North American populations of C. bitumineus each have three chromosomes due to...
متن کاملMultilevel effects of sublethal fenitrothion exposure in Chironomus riparius Mg. (Diptera, Chironomidae) larvae.
The effects of fenitrothion exposure on fourth-instar Chimnomus riparius larvae were investigated on biochemical, physiological, and population-level parameters. Biochemical effects were investigated through measurements of acetylcholinesterase and cytosolic superoxide dismutase activities. Water content and dry weight of the larvae were used as physiological parameters, and the emergence rate ...
