Abstract
The effectiveness of the canopy trap for female Tabanidae was increased significantly when l-octen-3-ol was used as an attractant. There was a threefold increase in the number of tabanids captured by traps with octenol (12.8 ± 2.1 females/trap) versus unbaited traps (3.7 ± 1.2 females/trap), and with dry ice plus octenol (72.1 ± 9.7 females/trap) versus traps with dry ice alone (24.7 ± 2.6 females/trap). There was also a significant increase in number of species in collections from traps with dry ice plus octenol (9.8 ± 0.9 species/trap) versus traps with dry ice alone (6.2 ± 0.9 species/trap). Tabanus molestus Say constituted 70% of the 1,038 tabanids collected.
