Abstract

The breeding sites and biology of Phlebotomus pedifer was investigated in the caves of the old focus of cutaneous leishmaniasis in Mt Elgon, Bungoma District, Kenya. Phlebotomus pedifer was found to rest mainly in the poorly lighted areas of the caves, on the roof, the floor of caves under objects, and in cracks and crevices inside the caves. The flies were also found in abundance in cracks and crevices outside the caves where hyraxes were found to rest. Immature stages of P. pedifer were recovered from wet areas of the floor of the caves. The biology of this species was investigated and the mean duration from egg to adult was 37 days.

Résumé

Les sites de reproduction et la biologie de Phlebotomus pedifer ont été étudiés dans les caves, daus un foyes du leishmaniose cutané, région de Mt Elgon, District de Bungoma, Kenya. On a observé que Phlebotomus pedifer se reposait principalement dans les parties sombres des caves, sur le toit, sur le plancher des caves, en dessous des objects, et dans les fissures et crevasses à l'intérieur des caves. On a aussi trouvé les mouches en abondance dans les fissures et crevasses à l'extérieur des caves où les rongeurs (hydraxes) se reposent. Les mouches P. pedifer au stade non mûr étaient récupérées des parties humides du plancher des caves. La biologie de ces espèces était étudiée et on a trouvé que la période moyenne entre le stade oeuf et le stade adulte était de 37 jours.
