title: [Use of traps in tsetse control: effects of treated and untreated supports].
abstract: Tsetse control trials were carried out in forest zone of Côte d'Ivoire with biconical traps. Some of the traps were impregnated with deltamethrin (1, 2 g per trap) and others were not. Results show a rapid and effective action of the treated supports. In nine days, the tsetse population had been reduced by 85% on the treated supports and by 60% on the non treated supports. After one month, a rapid decrease of the efficacy of the treated traps was observed. The fall in the effectiveness (more masked in the treated traps) was certainly due to heavy rains (875 mm) which caused an important increase in growth of vegetation.
