Abstract

Urine from the buffalo, Syncerus caffer, a natural host of the tsetse, has been shown previously to be a potent olfactory attractant for tsetse in the field. The attractant compounds have been found to be extractable into dichloromethane. Fractionation of the extracts by liquid flash chromatography yielded four fractions one of which gave a seven-fold increase in trap catches in the field compared to the control traps. Gas Chromatographie and gas chromatography–mass spectrometric analysis of this fraction revealed the presence of seven simple phenols including phenol itself.

Résumé

L'urine de buffle, Syncerus caffer un hôte naturel de mouche tsé-tsé, s'est récement montré d'être un attracteur potentiel d'olfaction pour la mouche tsé-tsé sur le terrain. Les composés de cet attracteur ont été trouvés extractable dans le dichlorométhane. Le fractionnement de ces extraits par le liquide chromatographique a donné quatre fractions dont l'une d'elles, placée dans les pièges de capture a permis de récolter sept fois plus de mouches que les pièges-contrôles. L'analyse de cette fraction par gaz chromatographique et par gaz chromatographique associé à la masse spectrométrique a révélé la présence de sept phénols simple comprenant le phénol lui-même.
