[Malaria transmission in Tiassalékro, a irrigated rice growing village situated in the South forest area of Côte d'Ivoire]. / Transmission du paludisme a Tiassalèkro, village de riziculture irriguèe situé en zone sud forestière de Côte d'Ivoire.

ABSTRACT

A longitudinal entomological study was carried out from January to June 2007 in the rice-growing area of Tiassaékro, a village located in the forest, South of Côte d'Ivoire. The study was based on samples of mosquitoes caught on human volunteers indoors and outdoors. During the 6 months of the study 29481 female mosquitoes were caught. The average biting rate was 272.9 bites per man per night (b/m/n). An. gambiae was the most predominant with 79.1% of mosquitoes caught. The average biting rate of An. gambiae was of 216 b/m/n. The biting activity of this species was noticed between 8 p.m. and 6 a.m. The estimated average sporozoite index was 0.32% (n = 3423 dissected). The inoculation rate was 0.69 ib/m/n with the highest rate (1.99 ib//n) recorded in April. The entomological parameters of the transmission are influenced by the different stages of rice growing.
