abstract
This study was conducted from November 2015 to October 2016 for larval collection and from December 2016 to September 2017 for adult collection, in two rubber producing localities (Bongo and Toupah) in southern Côte d’Ivoire. Overall, 39360 larvae of Culicidae was collected. After larval breeding, 28,364 adults were obtained containing six genus and 34 species. The most prevalent species in both areas were Aedes aegypti, Ae. africanus, Culex quinquefasciatus, Cx. nebulosus and Anopheles gambiae. Abundance of mosquitos larvae in Toupah (85.3%) and Bongo (80.2%) was higher in the rainy season comparing to the dry season. CDC light trap collected 4520 adult belonging to 5 genus and 16 species. From the 5 genus, Culex (62.6%) and Mansonia (32.4%) accounted for more than 95% of all mosquitoes collected. The high specific richness (16 species) and the high abundance (57,3% of specimens) of Culicidae were observed in Toupah area compared to Bongo area. Indeed, the abundance and diversity of Culicidae fauna are a serious epidemiological concern to the inhabitants of the study areas. Therefore, the effectiveness of bed net used are strongly recommended in order to reduce human and vector population contact and also the reduction of the prevalence of mosquito-borne diseases.
