Abstract Culicoides oxystoma Kieffer (Diptera: Ceratopogonidae) transmits many pathogens, including seven viruses, four protozoa and one nematode. This species has a wide distribution range across northern Afro‐tropical, Palearctic, Australian, Indo‐Malayan realms with broad host spectrum, cattle, buffaloes, sheep, pigs, dogs, horses even humans. The heterogeneous nature of ' blood‐feeding patterns is well documented, but the influence various blood meal sources on gut bacterial composition...
A comprehensive study was conducted on the life history parameters of an important vector Culicoides oxystoma Kieffer (Diptera: Ceratopogonidae), to standardize potential rearing procedures. Data traits and conditions are crucial for establishing laboratory colony conducting competence-based studies utilizing specimens with a known history. Six different substrate compositions were used rear larvae: S1: habitat mud containing cattle manure + nutrient broth yeast, S2: S3: broth, S4: S5:...
Five rare polar gynandromorphic specimens of Culicoides (Diptera, Ceratopogonidae), four oxystoma Kieffer, and one specimen Obsoletus group were studied. These individuals collected during pre-monsoon, monsoon post-monsoon seasons by using UV LED light traps from cattle shed poultry farm located in Purulia, West Bengal, India. The C. revealed a typical with male genitalia slender abdomen. It had the head, antenna, mouthparts, associated accessory structures together wings similar to that...
Abstract Defecation is one of the posterior‐station transmission routes for pathogens in haematophagous insects. Culicoides peregrinus Kieffer and oxystoma (Diptera: Ceratopogonidae) are proven vectors many arboviruses, most importantly bluetongue virus, protozoa, filarial nematodes livestock. Duration blood feeding defecation vary according to species. females take from their hosts acquire additional protein develop eggs. This study investigates bacterial communities defecated contents gut...
Culicoides oxystoma Kieffer (Diptera: Ceratopogonidae) has been vectoring several arboviruses, protozoa and nematodes, leading to mortality morbidity of livestock wild ruminants in the tropics subtropics. Insight into bacterial communities associated with vector species must be worked out. This work tries inventorize this important species. Acquisition gut microbiota may parental origin, while some are obtained through feeding during larval stages. possesses semi-aquatic life cycle...
Gut bacterial communities in insects provide several beneficial roles like nutrition, digestion, fecundity, and survival of the host. The microbial Culicoides spp. (Diptera: Ceratopogonidae) vary with parity, developmental stages, environmental factors. Previous studies have revealed presence hemolytic bacteria adult peregrinus Kieffer Ceratopogonidae), an important vector bluetongue virus (BTV). Our objectives were (i) to identify activities associated all life stages (ii) compare between...
During larval rearing of Culicoides peregrinus Kieffer (Diptera: Ceratopogonidae) it was obligatory to add a small quantity mud from habitat nutrient broth in culture plates. This initiated microbial growth plates which facilitated and development immature. The primary aim enumerate gut communities across the different life stages C. peregrinus. Amplicon sequencing V3-V4 hypervariable region (16S rDNA) done on Illumina Miseq platform detect bacterial at stages, while ITS regions (18S rRNA)...
The seven species of Culicoides spp. belonging to the Aterinervis Group subgenus Hoffmania Fox reported from India are revised. study is based on type material and fresh specimens trapped during Annual Biodiversity Assessment (2nd & 4th) Neora Valley National Park (NVNP) in Darjeeling-Sikkim Himalaya India. Comparative redescriptions adult male female isoregalis, C. neoregalis, pararegalis, pseudoregalis, quasiregalis, regalis subregalis provided along with formal transfer nominate species,...
Abstract Habitat selection of Culicoides spp. (Diptera: Ceratopogonidae) is influenced by the physicochemical factors such as temperature, pH, salinity, moisture, conductivity, organic and inorganic compounds substrates. These determine life history traits vectors. We studied influence substrate salinity (0–40 parts per thousand, ppt) pH (pH 1–13) on oviposition, egg hatching, larval survivability, adult emergence peregrinus Kieffer under laboratory conditions. Most eggs (80.74%) were laid...
