Hematophagous Flies in Dhofar (Sultanate of Oman):A Limiting Factor and a Potential Pathogenic Vector

In Dhofar, pastoralists take certain precautionary measures against hematophagous flies: Haematobia minuta Bezzi, Muscacrassirostris Stein and Forcipomyia (lasiohelea) whitcombei Boorman. Through their feeding on domesticated animals, these flies impedepasturing in certain areas during the rainy season (Khareef); hence they act as a limiting ecological factor and a custodian of the flora. Thepossibility that these flies could be potential pathogenic vectors has not been investigated in Oman, although in other parts of the world theyare recognized as carriers of disease agents. The paper draws attention to this issue in Dhofar.
