The promotion of pyrethroid impregnated bednets among the populations is a major activity of the National Malaria Vector Control Programs in African tropical countries. However pyrethroid resistance in Anopheles gambiae, a major malaria vector, has been observed in several parts of Côte-d'Ivoire since 1993. As insecticides used in agriculture against pests(More)
The involvement of members of the Anopheles gambiae complex Giles and An. funestus Giles and An. nili Theobald groups in the transmission of Plasmodium falciparum was recently investigated in the villages of Gbatta and Kpéhiri, which lie, respectively, in forest areas in the west and south of Côte d'Ivoire. Adult female mosquitoes were collected, using(More)
Long-lasting treatment kits, designed to transform untreated nets into long-lasting insecticidal nets (LLINs), may facilitate high coverage with LLINs where non-treated nets are in place. In this study, the efficacy of ICON® Maxx (Syngenta) was evaluated under laboratory conditions and in an experimental hut trial in central Côte d'Ivoire, where Anopheles(More)
We comparatively studied the dynamics of malaria transmission in the villages of Zatta (located in close proximity to an irrigated rice perimeter) and Tiémélékro (rural area with traditional agriculture), central Côte d'Ivoire. In the former village, the irrigated rice farming had been interrupted in 2003/2004 due to a farmers' conflict over land. In each(More)
A longitudinal entomologic study was carried out in the village of Ganse located in the Northeastern Ivory Coast from July 2000 to July 2001. The threefold purpose of the study was to index Plasmodium-carrying Anopheles species by capturing mosquitoes on human volunteers, collecting larvae in different dwelling types, and evaluating the involvement each(More)
Malaria control is heavily dependent on the use of insecticides that target adult mosquito vectors via insecticide treated nets (ITNs) or indoor residual spraying (IRS). Four classes of insecticide are approved for IRS but only pyrethroids are available for ITNs. The rapid rise in insecticide resistance in African malaria vectors has raised alarms about the(More)
Abstract From June 2007 to June 2008, entomological, malacological and parasitological investigations were carried out in five villages in close proximity to a small dam of Raf-fierkro in Bouaké, central Côte-d'Ivoire. The objective of the study was to identify vectors and intermediate host snails of parasitic diseases related to water, and to assess the(More)
A deeper understanding of the ecology and small-scale heterogeneity of malaria transmission is essential for the design of effective prevention, control and elimination interventions. The spatial and temporal distribution of malaria vectors was investigated in five villages in close proximity to a hydro-agricultural system in Côte d’Ivoire over the course(More)
