Abstract: From March to October 2015, an entomological study based on the diversity of culicidae and the determination of entomological parameters of the transmission of Plasmodium parasite was carried out in three quarters of Maga Subdivision. A total of 6469 mosquitoes were collected at the moment of a blood meal, the Anophelinae (3393/6469) presented a high number of 2431 Anopheles gambiae (37.58%) and 962 Anopheles funestus (14.87%). The anthropophilic culicinae (3076/6469) consisted of 2332 Culex quinquefasciatus (36.04%) and 744 Aedes aegypti (11.5%). During the period of study, the general rate of aggressiveness in Maga was 67.38 bite/man/night with 35.34 bite/man/night for Anophelinae and 32.04 bite/man/night for Culicidae. On the 3227 ovaries obtained from dissected female Anopheles, 2027 presented parous ovaries with an annual medium rate of parturity of PR = 62.81%. More than half of the adult of the population of Anopheles being parous, makes it possible to declare the locality of Maga as a risky malaria transmission area.
