Abstract

Two studies were undertaken to determine the species composition of the phlebotomine sandfly fauna in the Mokolo region, an endemic focus of cutaneous leishmaniasis in northern Cameroon. The preliminary survey conducted in July 1994 using sticky paper traps recorded 843 sandfly specimens, all belonging to the two genera of the Old World sandflies, Sergentomyia and Phlebotomits. The species included S. (Sergentomyia) schzvetzi, S. (Sergentomyia) antennata, S. (Parrotomyia) africana and P. (Phlebotomus) duboscqi: From January 1996 to December 1996, a total of 3241 sandflies were collected using sticky paper traps. In this sampling, six out of the total of eight species recorded were of the genus Sergentomyia. In addition to the species recorded in the preliminary study, S. (S.) bedfordi, S. (Grassomyia) squamipleuris, S. (Sintonius), clydei and P. (Anaphlebotomus) rodhaini were sampled in 1996. This is the first report of S. squamipleuris ir Cameroon. The implications of this study to the transmission of cutaneous leishmaniasis are discussed with particular reference to P. duboscqi, a known vector of the disease in the region.

Résumé

Deux enquêtes ont été menées pour déterminer les espèces constituant la faune phlébotomienne de la région de Mokolo, foyer endémique de la léishmaniose cutanée au Cameroun du Nord. Lors de l'échantillonnage préliminaire effectué en juillet 1994 par utilisation des pièges adhésifs en papier, 843 phlébotomes ont été capturés et tous appartenaient aux deux genres de phlébotomes très connus dans l'Ancien Monde: Sergentomyia et Phlebotomus. Les espèces rencontrées étaient Sergentomyia schwetzi, S. antennata, S. (Parrotomyia) africana et P. duboscqi. De Janvier 1996 à décembre 1996, 3241 phlébotomes étaient capturés à l'aide des mêmes pièges. Une prépondérance des espèces du genre Sergentomyia était également notée. Au cours de cet échantillonnage, six sur huit espèces collectées appartenaient au genre Sergentomyia. En plus des espèces capturées lors de l'échantillonnage préliminaire on a également noté la présence de S. bedfordi, S. (Grassomyia) squamipleuris, S. (Sintonius) clydei et P. (Anaphlebotomiis) rodhaini, lors de l'échantillonnage de 1996. Ce fut la première fois que S. squamipleuris a été signalé au Cameroun. Le présent article discute des implications de transmission de la léishmaniose cutanée avec un accent particulier sur P. duboscqi, vecteur connu de cette maladie dans la région.
