abstract
In the year 2011, an entomological study based on the evaluation of the anthropophilic fauna and especially on the determination of entomological parameters of the transmission of Plasmodium parasite was carried out in Maroua town Cameroon. Of a total of 1177 mosquitoes caught on human beings, female Anopheles represented only by Anopheles gambiae showed a fairly low number of (136/1177) that is 11.55% of the total number of Culicidae captured. Anthropophilic Culicinae, consisting solely of Culex quinquefasciatus alone accounts for 88.45% with a workforce of (1041/1177) of the total mosquitoes collected on human beings. The general aggressiveness rate is then Ar = 4.08 bites/man/night, is an annual aggressiveness 1491.68 bites/man/year in Maroua during the study period. The transmission study dealt only with the principal malaria vector, 136 female Anopheles gambiae caught on man gave an average aggression rate Ar = 0.47 bites/man/night, representing an annual rate of 171.55 bites/man/year aggressiveness. Out of 131 salivary glands of Anopheles gambiae dissected, only 13 females showed Plasmodium sporozoites in their salivary glands, a sporozoite index SI = 0.0 99. Infected female Anopheles bites in Maroua is estimated at Entomological Inoculation Rate (EIR) = 0.05infected bite/man/night, or 18.25 infected bite/man/year. This reflects a low level of the transmission of Plasmodium during the study period in Maroua. The average annual rate of parturity is estimated at PR = 51%.
