Abstract

The protozoan parasite, Trypanosoma evansi is transmitted mechanically between animals by tabanid flies (Family: Tabanidae). T. evansi causes the disease Surra, which produces significant mortality and production losses in a variety of mammals in endemic countries. Surra is an exotic disease and considered a high quarantine risk to Australia (AFFA, 2003), with Cape York regarded as a likely route of incursion. Thirty-four species of Tabanidae, including 14 species of Tabanus, were captured at 11 locations on Cape York and at Townsville, suggesting that appropriate species for Surra transmission are present in northern Australia. Trapping of tabanids in the Cape York region has allowed their distribution, trap-catch abundance and seasonal patterns to be analysed. These data have clarified the seasonal dynamics of different tabanid species. Further analysis of abundance and distribution in relation to weather and vegetation type could lead to prediction of the temporal and spatial abundance patterns of tabanids. This, in turn, would allow prediction of when and where the corresponding risk of vector transmission of Surra is potentially highest, in the event of an incursion. This information would be a valuable contribution to a risk map for incursion and establishment of Surra in the Cape York region, and would support the direction of surveillance and containment efforts.
