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).
