The spatial and temporal structure of non-biting midge (Diptera: Chironomidae) larvae assemblages and some environmental factors that affect their distribution were analyzed in a montane river and its tributaries in a temperate climate region of southernmost Brazil. In total, 69 taxa were recorded after four seasonal samplings (winter, spring, summer, and autumn). The dominant taxa were Rheotan...

Chironomid hemoglobins are potent allergens. The allergenic and antigenic activities of these hemoglobins are studied with the help of RAST, RAST inhibition and double immunodiffusion. Human as well as rabbit antisera were used. It was shown that hemoglobins are the main antigenic/allergenic components in extracts of Camptochironomus tentans larvae. Furthermore, immunological cross-reactivity a...

A comparative chromosome banding analysis of Chironomussolitus Linevich & Erbaeva, 1971 and Chironomusanthracinus Zetterstedt, 1860 from East Siberia (Lakes Baikal, Gusinoe, Arakhley and Irkutsk Reservoir) showed close similarity of banding sequences. Chironomussolitus differs from Chironomusanthracinus in one species-specific sequence of arm B. Arms C (43%) and D (30%) had inversion banding se...

We document the discovery of a unique flightless marine midge Pontomyia (Chironomidae) in the Indian Ocean, presenting descriptions and photographs of the insect and its environment at Christmas Island, Australia. The insect is identified as P. natans, with distinctive male genitalia and rudimentary claws on the hind legs. This species is widely distributed in the Pacific Ocean but the only pre...

Benthic habitats are linked by physical processes and are essential elements in assessing of the distribution dynamics of Chironomidae dipteran insects and their role in aquatic ecosystems. This work presents results of distribution patterns of chironomids larvae in 38 sites that are abundant in the study site, inhabiting the substrate of the main river channel, rapids, tributary brook, floodpl...

This study examined whether ecoparasitic larval Unionicola foili exhibited a sex bias when infecting laboratory populations of the host insect Chironomus tentans and whether an association with male or female midges increased the likelihood of larval mites returning to the aquatic habitat. When laboratory populations of C. tentans were exposed to larval U. foili, there was a higher prevalence o...
