Abstract: The elimination of most productive breeding sites for Aedes spp has been applied worldwide in order to keep vector density below a critical threshold. Key-breeding container plays important roles in determining the most suitable and effective methods for vector control. This study was conducted to identify the key-breeding container of Aedes spp. larvae as a baseline data for Cheras District and to suggest suitable Aedes prevention and control steps based on Integrated Vector Management strategies. An entomological survey was done in 20 Dengue outbreak localities in Cheras district, Kuala Lumpur, in 2016 involving all types of properties. The location of breeding was determined by indoor or outdoor, and type of mosquito species was identified. Descriptive statistics and chi-square analysis were done to identify differences in breeding containers by type of property (Low-rise vs High-rise). Statistical significance was set at P-value less 0.05. All the study sites were 100% positive for Aedes breeding. For all study sites, entomology indices showed a high risk of Aedes index (15%), medium risk for breeding index (55%) and medium risk for container index (70%). Of 546 potential breeding containers included in the survey, 11.7% were positive, indoor (2.6%) and outdoor (9.2%). The most common type of container was plastic container (30%) and there is no significant difference of indoor and outdoor breeding by high-rise and low rise, p-value= 0.0613. Artificial containers are key breeding habitats in dengue outbreaks. Therefore, community mobilisation towards eliminating human made containers, either indoor or outdoor, is vital for dengue control program.
