Abstract

Stable flies are important blood sucking flies of livestock and other mammals. They can transmit many parasites and pathogens. The present study was carried out to survey the stable flies at the horse stable of Faculty of Veterinary Science, Mahidol University from July to August 2013 using Vavoua traps. A total of 976 individuals of 2 species were captured; Stomoxys calcitrans (97.75%) and Stomoxys indicus (2.25%). The diurnal feeding activity of each species was observed during different period of times (06.00 to 18.00). Males of S. calcitrans showed peak of diurnal activity in the morning (08.00 to 10.00) and in the afternoon (14.00 to 16.00) whereas females showed a constant activity throughout the day. Both sexes of S. indicus showed peak of activity in the early morning (06.00 to 08.00) and the late afternoon (16.00 to 18.00). Some morphological characters (frontal index and body length) in both sexes of each species were also measured. Results of this study provide information that may be useful for stable fly control programs.
