Abstract: A cross-sectional survey was carried out during the period (August – November 2019) to identify baseline key containers and pupal productivity in Habila and Serba localities west Darfur, Sudan when dengue fever and chikungunya outbreak spread. The main objective of this study is to provide evidence - based data that can help in planning, implementation, and programmatic decision-making. The sample size of households (HH) for the productivity of immature stage survey was calculated following (operation1al guide for assessing the productivity of Aedes aegypti breeding sites, WHO 2011) in Serba and Habila. A preliminary survey and inspection of all households in the two areas was conducted on a daily basis between 07:00-01:00 hr. Data was analysed using MS (excel) and the parameters (HI, CI, BI, and PI) were calculated. Out of 14100 containers inspected, 1023 (7.8%) were found infested with larvae and pupa of the Aedes mosquito. The high container positivity was recorded in Serba: 646 (8.7%) out of 7354, and 306 (4.5%) out of 6746 in Habila. Major breeding containers were the clay jars (zeer) 572 (88.5%) out of 646 positive containers in Serba and 150 (49%) out of 306 positive containers in Habila. Jar clay pot (Zeer) is the major pupal productive container (95.4%) in Serba, followed by neglected pots 4 %. Whereas barrels are the major pupal productive container in Habila 42.5%, followed by zeers 35%, neglected pots 27.8% and lastly plastic water container 1.9%. Water source reduction coupled with community awareness raising should be implemented to minimize dengue and chikungunya risk as well as reduce Aedes aegypti indices to prophylactic levels.
