ABSTRACT
Mosquito-borne diseases are a major public health concern in the Caribbean. Domestic water-storage containers are preferred breeding habitats for synanthropic mosquito species, among which Aedes aegypti stands out due to its role in arbovirus transmission. To determine the microenvironmental features associated with container-dwelling mosquitoes, a house-to-house cross-sectional entomological survey was carried out in 9 Dominican provinces affected by Zika virus in 2016. All containers with the potential to store water were sampled, all immature mosquitoes were collected, and information on the type, capacity, volume of stored water, building material, presence of flowers, and house location was documented. The specimens were identified and larval indices (House index [HI], Container index [CI], Breteau index [BI], and Ae. aegypti Breeding Percentage) were applied. A total of 665 dwellings were surveyed across 30 neighborhoods. A total of 1,420 water-filled container habitats were sampled, 19.3% of which harbored immature mosquitoes of 5 species, including 4 important vectors. The dominance of Ae. aegypti was marked, as it was present in all sampled neighborhoods, inhabiting 272 containers (19.1%). Larval indices were higher than the threshold values accepted (5% for the HI and BI, and 3% for the CI) in almost all neighborhoods. The presence of Aedes spp. was associated with the serviceability of water-holding containers (χ2 = 16.56522; P < 0.001), and the difference in volume between water-holding containers was associated with the presence of Aedes spp. infection (χ2 = 4; P < 0.001), the containers up to 5 liters being the most infested. This is the first entomological research based on synanthropic mosquito breeding habitats that cover urban areas of the 3 macro-regions of the Dominican Republic.
