Seasonal abundance of horse flies (Diptera: Tabanidae) and stable fly (Diptera:Muscidae) collected by Nzi trap within Taw Area, Myanmar

Blood sucking flies are vectors of medical and veterinary importance. Within Nay Pyi Taw area, a longitudinal study was conducted to collect blood sucking fly samples between January and December, 2011. A total of 2,717 fly samples including 1,506 samples of blood sucking flies and 1,211 samples of non blood sucking flies were collected throughout a year. Collected blood sucking flies were Stomoxys spp. (76%), Tabanus spp. (23.4%), Haematopota spp. (0.3%) and Chrysops spp. (0.3%). The number of blood sucking flies peaked in October in winter (dry) season. Among the collected flies, Stomoxys spp. was found with the highest population in rainy and winter seasons. However, in the summer season, the number of Tabanus spp. was found the highest population. Haematopota and Chrysops spp. were observed only in rainy and winter season. No significant relationship was observed between the number of blood sucking flies and meteorological data such as monthly temperature and monthly rainfall during the study period. This is the first report on seasonal abundance of Tabanidae and Stomoxys flies in Myanmar.
