Resumo: This study aims to assess the seasonal distribution of Aedes aegypti from May 2013-April 2014 in Dandji, Southern Benin. The study was based on Ae. aegypti immature stages (larvae/pupae) sampling from domestic, peri-domestic, and natural water sources and were reared to adults. The collections were made during the dry and rainy seasons. During the study, a total number of 18,658 mosquitoes were collected, where 15,204 were collected by human landing catvhes, 303 with biogents sentinel trap, 3,038 with Indoor Pyrethrum Spray Catches, and 48 with Gravid traps. Among the 18,593 of Ae. aegypti collected, the female populations was significantly higher than the male populations. From the 13,834 females, 1,380 were blood-fed. Adult's collection was high during the two rainy seasons (June-July and October-November) but declined in the two dry seasons (December-March and August-September). At Dandji, the average Human Biting Rates obtained during rainy seasons was significantly higher than those obtained during the dry seasons.
