Many Diptera (true flies) are of medical and veterinary importance, particularly blood-sucking flies. Biting or blood-sucking cause blood loss, severe irritation, annoyance, interfere with the animals' feeding and resting, reduction of weight gain and milk production of dairy cattle, and transmission of many pathogens to humans and animals. These effects may lead to economic losses for farmers. To investigate the species diversity and seasonal abundance of blood-sucking flies in dairy farms, the flies were trapped and collected using Malaise traps from five different dairy farms in Amphur Muaklek of Saraburi province during June 2008 to May 2009. A total of 17,922 adult Diptera belonging to 2 families (Tabanidae and Muscidae), 4 genera and 12 species such as Haematopota glenni, H. pachycera, H. singularis, H. varifrons, Tabanus konis, T. rubidus, T. systenus, T. striatus, Haematobia irritans exigua and Stomoxys spp. were caught. Stomoxys spp. had the highest abundance (98 percent) followed by the Haematobia (1.3 percent), Haematopota (0.5 percent) and Tabanus (0.2 percent). The seasonal factor had the impact on abundance of these flies since an increase in number correlated with the beginning of rainfall and a decline in the dry season. These results suggested that removing or spreading straw and manure plies can destroy immature stages at their breeding sites particularly before the raining season so that this may reduce the population of these blood-sucking flies.
