Species diversity and seasonal density of tabanid flies in a dairy farm in Nakhon Ratchasima province and a zoo in Chon Buri province, Thailand, Including an Iconographical key
Abstract:
Tabanids, the largest blood sucking and biting insects, can take blood meals from various animal hosts, and are a potential mechanical vector of blood pathogens for livestock and humans. Knowledge of their species-diversity can be used to identify their larval habitats and their seasonal and diurnal activities. The study was performed to determine the species diversity and the diurnal activity of the tabanids in a dairy cattle farm of Wang Nam Khiao District, Nakhon Ratchasima Province and in the Khao Khiao Open Zoo, Chon-buri Province, Thailand. Nzi traps were used to capture tabanid flies for periods of 24 hours, once every month in the farm and every two months in the zoo during a 1 year period. Part1; A total of 488 specimens from 2 sites were collected with nine species belonging to three genera and all were morphologically identified. The most abundant genus was Tabanus with 6 species, representing 92.8 %, followed by Chrysops with two species by 6.55 % and one species of Haematopota (0.6%). Tabanus striatus was found the most abundant with 33.2 %. Prominent peak of flies was seen between 10.00 hr and 14.00 hr, respectively for two sites. The low diversity was observed, especially in the dairy farm, suggesting that a few species may involve in the epidemiological importance. Part2; An iconographical key of Tabanus megalops was prepared for the first time by tri-dimensional picture (3D). This finding will assist in designing the appropriate prevention and control strategies.
