Distribution and abundance of Stomoxyini flies (Diptera: Muscidae) in Thailand.

Stomoxyini flies (Diptera: Muscidae) include species of parasitic flies of medical and veterinary importance. The adult flies feed on the blood of mammals and may transmit several parasites and pathogens. We conducted an entomological survey of Stomoxyini flies from different sites in Thailand. Stomoxyini flies were collected at four major types of sites: zoos, livestock farms, wildlife conservation areas and a national park using vavoua traps between November 2010 and April 2011. A total of 3,314 Stomoxyini flies belonging to the genera Stomoxys, Haematobosca, Haematostoma and Haematobia were collected. Eight species were identified: S. calcitrans (46.6%), S. uruma (26.8%), S. pulla (4.3%), S. indicus (0.7%), S. sitiens (0.1%), H. sanguinolenta (11.2 %), H. austeni (0.5%) and H. irritans exigua (9.8%). The diversity of Stomoxyini flies in the livestock farms was higher than the other sites. Altitude correlated with the number of flies. This study provides information that may be useful for Stomoxyini flies control.
