Etude Ecologique Et Entomologique Des Culicides Larvaires Des Gites De La Province De Kenitra (Maroc)

Abstract

Mosquitoes are considered the source of nuisances and used as vectors of major pathogens for humans and animals. Despite the existence of many ways of control, supervising their populations remains a challenge forced by a delicate knowledge of their dynamics in space and time. Hence the need to conduct an entomological and ecological study of breeding sites in the province of Kenitra in order to acheive an inventory of culicidiennes species collected at eight stations of surface water with the measurement of physical-chemical parameters of these waters during several month from April to June 2012. The results revealed the presence of two species of mosquitoes, the Anopheles labranchiae and the Culex pipiens. The first type has a very low density at three stations, while the second one has a very high density in five stations. Furthermore, concentrations and measured values of the physico-chemical parameters allowed to highlight a correlation between the quality of waterin the stations and dynamics of mosquitoes. Thus, the Anopheles attend frequently the well-oxygenated and unpolluted stations (O2 between 2,53 and 3,65 mg/l; BOD5 between 3 and 15 mg/l) against the Culex (O2 between 3,85 and 8,12mg/l, BOD5 between 10 and 100 mg/ l).

“…In this zone, a high density of Culex pipiens exists besides other mosquito species such as Anopheles labranchiae (Marc et al . ).…”

“…These bioclimatic conditions are optimal for the survival of the vector and the circulation of WNV (Calistri et al, 2010). In this zone, a high density of Culex pipiens exists besides other mosquito species such as Anopheles labranchiae (Marc et al 2016).…”

Distribution spatiale et saisonnière des gîtes larvaires des moustiques dans les espaces agricoles de la zone de Mouila, Gabon

“…Les moustiques constituent un problème majeur en santé humaine. En effet, ils sont impliqués dans la transmission de plusieurs agents pathogènes responsables de maladies telles que le paludisme, le chikungunya, les filarioses, les encéphalites, la fièvre de la vallée du Rift, la fièvre jaune, la fièvre Zika (Ikram et al, 2016). Ces maladies à transmission vectorielle figurent parmi les plusimportantes en santé humaine et animale (Becker et al, 2010).…”
