Antennal Responses of Glossina morsitans morsitans to Buffalo Urine, a Potent Olfactory Attractant of Tsetse

Research Article

Abstract

Behavioural-antennal responses of tsetse to buffalo urine, which has been identified as a potent olfactory attractant, were investigated. Tsetse Glossina morsitans morsitans rapidly raised their antennae upon stimulation with the odour of buffalo urine. Flies showed a clear preference for the undiluted urine, though antejinal responses even to 100,000 × diluted urine were significantly different from control, indicating the high efficacy of the attracting compounds present in it. Fresh buffalo urine was the most attracting as compared to 4- and 8-day-old urine. The dichloromethane extract of fresh urine was as active as the natural product, indicating that the attracting compounds were extractable into dichloromethane. Under laboratory conditions, responses of males to the urine were significantly more than females.

Résumé

On a étudiés les réactions des antennes des tsetse à l’urine de buffle, qui a été identifiée comme une substance olfactive puissante qui attire les tsetse.

Les mouches tsetse Glossina morsitans morsitans élevaient rapidment leurs antennes lorsqu’elles étaient stimulées par l’odeur d’urine de buffle. Les mouches montraient une préférence pur l’urine non diluée, quoique les réactions des antennes à l’urine même diluée 100,000 × étaient significative différentes comparées à celles des mouches de référence, montrant ainsi la haute efficacitée de ses composantes attractives. L’urine fraiche de buffle etait la plus attrayante comparée à celle qui était agee de 4 a 8 jours. L’extrait de dichlorométhane provenant de l’urine fraiche était aussi actif que le produit naturel, montrant que les composantes actives pouvaient être extraites du dichlorométhane. Dans des conditions de laboratoire, les réactions des mâles à l’urine étaint significativement moins importantes que celles des femmelles.
