| Summary: | Background: Major determinant of dengue incidence is interaction between ecology, vector bionomics, and social factors. Objectives: The objective of the study is to find out bio-eco-social determinants of Aedes breeding. Methods: Background, household, entomological, and knowledge, attitude, and practice (KAP) surveys were undertaken post- and premonsoon showers from May to June 2016 in urban and rural practice area of medical college. Results: A total of 181 and 204 households, 131 and 137 individuals, and 1250 and 1268 water-holding containers were included in household survey, KAP survey, and larval survey in urban slum and rural area, respectively. In both locations, maximum water-holding containers were indoors (41.4% and 61.8%, respectively); however, maximum positivity was peridomestic (63.6% and 83.1%, respectively). Pupae per container were 0.9 and 1.9 in respective locations and pupae per person were 1.2 and 2.3, respectively. Container positivity was seen in containers with rain as water source (8.8%) as well as among those who were never used (10.7%). Irregular water supply was significantly more in rural area (P < 0.05). KAP survey revealed that majority (90.1% and 71.5%, respectively) had heard about dengue, with significantly higher knowledge in urban slum, and television was the main source of information. Majority (89% and 83%, respectively) were unaware that peak biting time of Aedes is daytime. Use of mosquito repellent coils was the predominant preventive practice (46.6% and 61.2%, respectively). Pupae were reared; all were found to be Aedes aegypti. Conclusions: Despite enhanced awareness campaigns, an integrated vector management approach is required for prevention of dengue.
