Abstract

Indoor-resting blood-fed Anopheles gambicie s.l. were collected from selected localities in Ethiopia. Anopheles arabiensis was the only sibling species identified. Paracentric chromosomal inversion polymorphisms were observed on the 2R and 3R arms. A significant excess of heterozygotes was obtained in samples from Siile carrying the 3Ra inversion. Similarly, significant variation was seen in the frequencies of the 3Ra inversion between the study localities. The observed intraspecific inversion polymorphisms relative to indoor resting behaviour are discussed.

Résumé

Les anophèles (Anopheles gambiae) gorgés de sang ont été collectés à l'intérieur des habitations préablement sélectionnées en Ethiope. Anopheles arabiensis est la seule espèce de lignée pure identifiée. Les polymorphismes résultant d'une inversion chromosomique étaient observés sur les bras 2R et 3R. Un nombre excessif d'hétérozygotes comportant une inversion du type 3 Ra fut observé au sein d'échantillons provenant de Sille. De même, une variation significative fut notée la fréquence d'inversion 3 Ra au sein des localités étudiées. Les polymorphismes d'une inversion intraspécifique observée, relatifs au comportement des moustiques gorgés retrouvés à l'interieur des habitations sont dicutés.
