خانواده‌ Chironomidae (Diptera: Insecta) با داشتن فراوان‌ترین و متنوع‌ترین حشرات گسترش جهانی دارد و در اغلب اکوسیستم‌های آب ‌شیرین از جمله آب‌های داخلی ایران یافت می‌شود. با وجود این، پژوهش‌های معدودی برای شناسایی این گروه در ایران انجام شده و دانش موجود از گوناگونی فون و پراکندگی آنها در کشور بسیار ناچیز است. برای شناخت لاروهای خانواده‌ Chironomidae در رودخانه‌ ماربر، استان اصفهان، نمونه‌بردار...

First specific records of Tanytarsus van der Wulp from the Ecuadorian mainland based on detailed descriptions are presented. Tanytarsus cayambe sp. nov. shows an interesting set of characters known from several Neotropical Tanytarsus as well as from species of the recurvatus group of the northern distribution. Tanytarsus cotopaxi sp. nov. is placed in the riopreto species group; as a result an ...

The effect of metal enrichment on chironomid communities was examined in streams receiving mine drainage from metal mining operations in New Brunswick, Canada. At five sites receiving mine drainage, metal concentrations were significantly (p < 0.05) elevated in water (Zn), periphyton (Cd, Co, Cu, and Zn), and chironomid tissue (Cu, Cd, and Zn) relative to five paired reference locations. Metal ...

We present the first results of study aiming to investigate diversity non-biting midges (Diptera: Chironomidae) fauna Skadar Lake system (Montenegro and Albania), a well-known hotspot freshwater biodiversity composed by young lake (originated 1200 before present) its old springs during Pliocene). During study, 8,147 COI barcodes were obtained revealed presence 474 BINs 586 OTUs assigned 148 spe...

Solar ultraviolet radiation (UVR) can reduce the photosynthesis and growth of benthic diatom communities in shallow freshwater. Nevertheless, greater amounts of algae accumulate in UVR-exposed habitats than in UVR-protected environments. Near-ultraviolet (UVA wavelengths of 320 to 400 nanometers) and mid-ultraviolet (UVB, wavelengths of 280 to 320 nanometers) radiation also inhibit algal consum...

Predators may affect prey population growth and community diversity through density mediated lethal and trait mediated non-lethal effects that influence phenotypic traits of prey. We tested experimentally the roles of thinning the density of prey (lethality) in the absence of predator cues and density and trait mediated effects (lethality + intimidation) of predatory midge Corethrella appendicu...

BACKGROUND Aquatic insects are the major groups of arthropods that spend some parts of their life cycle in the water. These insects play an important role for transmission of some human and animal diseases. There is few information about the aquatic insects fauna of Iran. METHODS To study the aquatic insects fauna, adult, nymphal and larval collections were carried out from different habitats...

Data about the karyotype characteristics, features of chromosomal polymorphism and larval morphology of populations of Chironomusbernensis Wülker & Klötzli, 1973 (Diptera, Chironomidae) from the Central Caucasus (the northern macroslope) and Ciscaucasia are presented. The characteristics of the pericentromeric regions of the long chromosomes of this species from Caucasian populations were very ...
