Abstract

Mandibles of females of 10 species of mosquitoes from five genera; hypopharynx of females of 26 species from 11 genera; and laciniae of females of 31 species from 14 genera, were examined using scanning electron microscopy. Mandibular teeth are present in Anopheles and Armigeres females, but absent in Aedes, Culiseta, and Culex. Interdigitating cuticular projections are present at the tip of the hypopharynx in all females examined. The salivary canal is open both at the tip as well as dorsally along a longitudinal slit. The average number of lateral teeth on the maxillary stylets varies according to species. Mesial and vestigial teeth are present in some species. There is no correlation between number of maxillary teeth and specific hosts of mosquito species. The function of stylet structure in feeding is discussed.

Résumé

Une étude au microscope à balayage électronique a été réalisée sur les mandibules, l'hypopharynx et les lacinies de femelles de maringouins. L'étude des mandibules porta sur 10 espèces appartenant à cinq genres, celle de l'hypopharynx porta sur 26 espèces appartenant à 11 genres, et celle des lacinies, sur 31 espèces appartenant à 14 genres. Des dents mandibulaires sont présentes chez les femelles d'Anopheles et d'Armigeres, mais absentes chez celles d'Aedes, Culiseta et Culex. Il existe des projections cuticulaires enchevêtrées au bout de l'hypopharynx de toutes les femelles étudiées. Le canal salivaire est ouvert à son extrémité, de même que dorsalement, par une fente longitudinale. Le nombre moyen de dents latérales des stylets maxillaires varie suivant l'espèce. Des dents médianes et des dents vestigiales sont présentes chez quelques espèces. Il n'y a pas de corrélation entre le nombre de dents maxillaires et les hôtes spécifiques des espèces de maringouins. On discute du rôle de la structure du stylet dans l'alimentation.
