Sažetak
For the collection of horse flies (Tabanidae) different types of traps are used worldwide. The efficiency of three types of traps (the standard canopy trap, small modified canopy trap, and shiny black plastic oil trap) was studied on the Badija islet in the Korčula archipelago, Croatia. The standard canopy trap and a small modified canopy trap were baited with 1-octen-3-ol and represented an olfactory trap. Shiny black plastic sheet was covered with yellow salad oil represented a visual trap. A total of 3278 specimens of the three species classified in two genera were collected. A significantly greater number of horse flies was collected in a shiny black plastic oil trap, i.e. 16.5 times more specimens than in standard canopy traps and 44 times more than in a small modified canopy trap. The most abundant species was Tabanus shannonellus Kröber, 1936 it comprised 98.17% of all horse flies collected. Furthermore, T. shannonellus represented the most abundant species sampled in all three types of traps. In the collected sample the males represented 58.66% while the females represented 41.34% of the total. The females were only collected in a standard canopy and small modified canopy traps. Finally, the great effectiveness of the shiny black plastic oil trap in comparison to the two types of canopy traps baited with 1-octen-3-ol can be explained by positive polarotaxis which had recently been established for the horse flies.
