Abstract: Vector- borne diseases account for significant morbidity and mortality worldwide. This is especially true for resource-poor countries and poor and marginalized populations. The current study was carried out during May 2016 – April 2017 Elfasher Locality, North Darfur State, Sudan to determine to determine seasonal and geographical distribution, and larval habitats of Aedes mosquitoes. A cross-sectional surveys was conducted. The sample size of households (HH) surveyed for the productivity of immature stage was calculated following WHO (2011) in four Almasani, Elsalam, Enasr and Alreef neighborhoods. Larval collection was carried out three days/ month between 07:00-01:00 hr. Larvae and pupae from containers collected identified in the laboratory. Data was analyzed using SPSS version. 20. Ae. aegypti was the predominant species the locality.Out of 480 HH visited, 69 were found positive for larvae (14.4%). A total of 1,724 potential breeding sites were reported and 5.5% proved to be positive. The major breeding containers were the clay jars 1,018 (59.0%), followed by barrels 768 (44.5%). The highly positive containers were the jars (33.2%). followed by the barrels (2.6%) and water tanks/others (0.3%). The highest house index (HI) was 35% during November, followed by September (27.5%). The highest Breteau indices (BI) were 45% during August, followed by September and November (25% for each). The container indices (CI) were as follows: 12% for August, and 11.5% for September. The pupal demographic-index (P/DI) was 20.5% for August and 3% foe September. Significant differences were detected between these indices in the dry- and wet- seasons, except HI. Highly significant differences between number of larvae and pupae in different seasons were detected. Therefore, community mobilization should be a priority in controlling Ae. aegypti populations and risk.
