Abstract

Between May 1984 and December 1985, the population of immature stages of Anopheles arabiensis was sampled by the dip method at sites close to two villages in Mwea Irrigation Scheme, Kenya. Larval presence corresponded to rainy seasons and the flooding phase of the rice cycle. No larvae were found during the postharvest dry season. The instar composition, age distribution and survivorship curves for the different stages were determined. Pupal productivity for Mwea rice fields was estimated to be 1% of the total immature population.

Résumé

Entre mai 1984 et décembre 1985, la population des larves de Anophèles arabiensis etaient etudiés par la méthode d'immersion près des deux villages de la région irriguée de Mwea au Kenya. La présence des larves correspondaient avec les saisons pluvieux et l'inondation des champs de riz. Ils n'avaient pas les larves trouvaient près de la moisson, pendant la saison sèche. La composition des larves, la distribution de L'âge, et les courbes de survie etaient résolus. La productivité des mostiques An. arabiensis de Mwea etaient estimés être 1% de la population total pas mûr.
