Technical Abstract: Tabanidae, commonly known as horse, deer or yellow flies, and greenheads, are important pests of man and livestock. Outdoor recreation is often hampered by the vicious biting habits of female tabanids. Pastured cattle and other livestock may suffer severely from heavy attacks of tabanids. Many reports have been published relative to the mechanical and biological transmission of disease organisms by female tabanids. Prospects for control by traditional methods are not particularly good. The overall objective of this study was to evaluate various known types of management, and/or nuisance reduction. Four types of traps (Canopy, NZ1, F2 and Biconical) were evaluated baited and unbaited with various combinations of semiochemical attractants. The semiochemicals tested included carbon dioxide (dry ice), 1-octen-3-ol (octenol) and acetone. Data obtained in these studies indicate that the relative efficacy of the various trap types sand bait combinations depends very much on the species of tabanid present. In general the unbaited NZ1 trap captured more specimens than any other unbaited trap type. Tabanus lineola species complex was the most abundant for most of the study.
