Abstract

Behavioural and electrophysiological (EAG) studies were undertaken to determine the olfactory selectivity of the antennae of Glossina morsitans morsitans Westwood and Glossina pallidipes Austen to phenolic kairomones. Responses of both species to 3-alkylphenols increased as the alkyl chain increased from one carbon atom to three, while the opposite trend was observed with 4-alkylphenols. These results indicated that 4-cresol and 3-n-propylphenol are the most stimulatory of the two respective groups of phenols. However, comparison of the responses indicated differences in the sensitivities of the chemoreceptor systems of the two species. Hence different compositions of the phenols may be required to best attract these species. Probable interactions of the phenols with the binding sites on the receptor surface are discussed.

Résumé

Le comportement et l'electrophysiologie des glossines pour determiner la sélection olfactorielle des antennes de Glossina morsitans morsitans Westwood et Glossina pallidipes Austen à certaines substances phénoliques furent étudiés. Les reponses des antennes de deux espèces avaient augmenté avec l'accroissement de la chaine alcyl d'un à trois atomes de carbone, contrairement aux 4 alcylphenoles. Ces résultats indiquent que les substances 4-cresole et 3-n-propylphenole étaient les plus stimulatrices de deux phénoles. D'autre part une comparaison des reponses avait indiqué certaines différences en ce qui concerne les systèmes chémorécepteurs de deux espèces. De ce fait les phénols de différentes compositions pourront être nécessaire pour une attraction efficace. Les intéractions probables de phénols avec les zones de contact des récepteurs furent discuter.
