Abstract
Spatial analysis of entomological parameters in relation to the incidence of dengue cases was carried out by using various entomological indices such as house index, container index, breteau index and pupal index. Various entomological parameters in three pre-identified risk areas were compared. Except container and breteau indices of St. aegypti in relation to water storage breeding sources, all other larval indices with respect to type of habitats as well as species did not differ significantly (P>0.05). This indicates that the risk factors are highly variable and dynamic and not necessarily continue in its magnitude. The container and breteau indices of St. aegypti in relation to water storage breeding sources was found significantly (p<0.05) higher in high risk areas and had shown significant relationship between the areas selected as low, medium and high incidence of dengue cases. This clearly indicates that the entomological indications with respect to the vector mosquito can be used as risk factors to predict the outbreaks and preparedness to prevent the same.
