ThesisItem Open Access MORPHOLOGICAL AND MOLECULAR IDENTIFICATION OF TABANIDS IN WESTERN GHATS OF KARNATAKA AND EVALUATION OF FLY TRAPS(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2021-01-01) RAJU METRI; G. C. PUTTALAKSHMAMMATabanids are haematophagous flies of medical and veterinary importance. The study was conducted from March 2019 to February 2020 to record the prevalence of flies in Western Ghats of Belagavi division Karnataka by both morphological and molecular methods of identification. A total of 912 flies belong to twenty species were found to be prevalent viz., T. indianus, T. biannularis, T. diversifrons, T. sexcinctus, T. gertrudae, T. triceps, T. dorsilinea, T. rubidus, T. jucundus, T. auristriatus, T. tenebrosus, H. montana, H. javana, H. longipennis, H. brevis, H. albimedia, C. dispar, C. pellucidus, A. virgo and P. taprobanes. T. jucundus was reported for the first time from Karnataka. The season wise prevalence revealed highest number of species were prevalent during rainy season (17 species) followed by summer (9 species) and winter (4 species). The most diverse genus was Tabanus with 11 species followed by Haematopota with five species, Chrysops with two species and Atylotus and Philoliche with one species each. The morphometric characters of 20 species of tabanids with 10 flies of each species was studied and grouped into large, medium and small flies. The DNA barcoding of twenty different flies was carried out targeting COI a 658 bp amplicon. The sequence of these species after BLAST analysis confirmed the species which was identified based on morphology. The sequence of these species submitted to GenBank and barcode was generated. Phylogenetic analysis of 20 species was carried out and highest and lowest interspecific divergence was found between Philoliche taprobanes and Chrysops dispar (18%); and Tabanus tenebrosus and Tabanus indianus (1%), respectively. A total of 9974 tabanid and Stomoxys flies belonging to eight species were caught by Nzi, modified Manning and H-traps. Nzi trap was superior to the modified Manning and H-traps in collecting tabanid flies. Approximately three times more flies caught by traps baited with fermented (aged) cow urine than unbaited traps. The duration of the olfactory attractive property of fermented (aged) cow urine was tested and it was found to be effective for 12 days.ThesisItem Open Access STUDIES ON THE EFFICACY OF SOME ANTICOCCIDIAL DRUGS IN INDUCED COCCIDIAL INFECTIONS OF BROILER CHICKENS(Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2009) RAJU METRIPoultry rearing has always been an integral component of livestock production system in India
