Tabanid Fauna (Diptera: Tabanidae) along The Lower Most Gangetic Plains of India: A Taxonomic Approach
Abstract
True flies of family Tabanidae (Brachycera, Tabanomorpha) refers to group of sturdy, handsome, large headed flies devoid of large bristles and with colourful eyes. The present study reports 21 species under 6 genera, 4 tribes and 2 subfamilies from the Gangetic plains of West Bengal. These are also keyed, diagnosed and their distribution pattern discussed. Among these Chrysops designatus Ricardo (1911), Tabanus dorsiger Wiedemann (1821), Tabanus (Tabanus) optatus Walker (1856), Tabanus (Tabanus) tenens Walker (1850), and Haematopota tessellata Ricardo, (1906) are new records from the lowermost Gangetic plains and also from West Bengal. Continuous distribution pattern was observed with these flies of veterinary importance and haematophagous nature.
... The present study was in concurrence with Vasudeva (2007) [7] observed maximum tabanid activity during monsoon period from Rajiv Gandhi National Park, Karnataka, India. However, Maity et al. (2017) [15] reported that the abundance was more during the rainy season and declined during winter season. Tabanidae are abundant mainly throughout the year with a little decline in mid to higher elevations during winter (Maity et al., 2015) [16] . ...

The aim of the present study was to explore the seasonal activity of tabanids in the Western Ghats of Karnataka. The study was carried out during all the seasons of the flight period March, 2019 to February 2020. A total of 912 specimens of tabanids were collected and identified belong to 5 different genera grouped into 20 species. The horse flies began flying during March-2019 and its flight period lasted until February-2020 with difference in number and species composition. The peak of seasonal abundance was observed during the last week of June. The most abundant species in the horse fly assemblages in the Western Ghats of Karnataka was Tabanus diversifrons Ricardo comprising of 18.64%, followed by Tabanus indianus Ricardo (9. 21%), Atylotus virgo Wiedemann (8.33%), Tabanus biannularis Philip (8.11%), Tabanus dorsilinea Wiedemann (7.13%), Tabanus rubidus Wiedemann (7.02%), Tabanus jucundus Walker (5.81%), Haematopota montana Ricardo (5.37%), Tabanus gertrudae Philip and Tabanus triceps Thunberg 5.04% each, Chrysops dispar Fabricius 3.84%, Haematopota javana Wiedemann 3.51%, Haematopota Longipennis Stone and Philip (2.96%), Haematopota brevis Ricardo (2.52%), Tabanus sexcinctus Ricardo and Philoliche taprobanes Walker 2.08% each, Tabanus tenebrosus Walker (1.43%), Tabanus auristriatus Ricardo (1.21%), and least abundance was observed in Haematopota albimedia Stone and Philip and Chrysops pellucidus Fabricius with 0.33% each. The largest number of specimens of Tabanus diversifrons Ricardo was collected during the peak of seasonal abundance of horse flies in the Western Ghats of Karnataka. Among the 20 species recorded in the present study, 7 species were proven vector for Surra, Anthrax, Blackleg and Haemorrhagic septicaemia in domestic and wild animals.
