Abstract

More than 2.5 billion people, in more than 100 countries, are estimated to live in risk areas for the transmission of dengue. We investigated the production of immature forms in different types of containers. Larvae and pupae presence were inspected in 747 containers in 300 dwellings in Rio de Janeiro state, Brazil. The statistical significance of the differences of immature forms was calculated for different groups of recipients and classified according to the type of use, volume, and material. Containers used to store water and those classified as garbage enclosed 90.2% of the larvae and 88.9% of the pupae. We concluded that a wider covering of more regular water supply, as well as regular garbage collection, are decisive factors for an effective control of dengue vector.
