Response of Tabanidae (Diptera) to natural and synthetic olfactory attractants

The attraction of female tabanids to Malaise traps and canopy traps baited with aged horse urine, 1- octen-3-ol, or a combination of aged horse urine and acetone was studied in the Kopački rit Nature Park in Eastern Croatia. Malaise traps captured very few tabanids relative to canopy traps. The number of females of Tabanus tergestinus and Haematopota pluvialis collected from 1-octen-3-ol baited canopy traps differed significantly from traps baited with aged horse urine. However, the number of females of Tabanus bromius, Atylotus loewianus and Tabanus maculicornis collected from canopy traps baited with 1-octen-3-ol and aged horse urine did not differ significantly. Canopy traps baited with aged horse urine collected significantly more Tabanus sudeticus than did traps baited with 1-octen-3-ol. Canopy traps baited with 1-octen-3-ol collected eight times more tabanids than unbaited traps, whereas canopy traps baited with aged horse urine and a combination of aged horse urine and acetone collected seven and four times as many tabanids, respectively, as did unbaited traps. It appears that 1-octen-3-ol and aged horse urine are very effective attractants for tabanids in this part of Europe. Tabanus bromius was the most abundant species with 53.14% in the sample collected by canopy traps.
