    Abstract:
    Prompted by report of large number of dengue fever cases in township of Rourkela steel plant, entomological surveys were carried out to know the distribution and extent of Aedes breeding in and around the dengue fever affected areas. Out of 2062 water containers searched, 819 were positive for Aedes larvae. The house index (HI), container index (CI) and Breteau index (BI) were 53.4, 39.7 and 118.5 respectively. 27.9% of the houses had single breeding habitats. The breateau index of single storeyed houses and double storeyed buildings was 149.8 and 54.6 respectively, showing that the single storeyed houses have more potential for Aedes breeding. The breeding preference ratio (BPR) was highest for plastic containers. Three species of Aedes were found breeding in different habitats and Aedes aegypti was found breeding in coolers, cement tanks, tyres and miscellaneous containers with a prevalence rate of 13.2%. The role of entomological surveillance and health education has been highlighted for the control of disease through community participation.
