Attractiveness for Tabanidae of various Glossina traps with or without olfactory attractants : Preliminary results in Burkina Faso

Abstract

During the dry season, three experiments were performed in the subhumid Savannah area of Burkina Faso in view of comparing the attractiveness and efficacy of five different traps for Glossina against Tabanidae together with the evaluation of two olfactory attractants. The NG-2G and F3 traps and the screen-trap were significantly more effective (x 1.7 to 8.7) than the biconical and monoconical ones. Metacresol increased the catches by an average of 1.5 fold, and the metacresol/octenol association (3/1) 2.5 fold in comparison with the control trap with no attractant at all.
