The abundance of Aedes aegypti in urban areas is a sanitary problem of importance in our country because of the diseases it transmits. The objective of this work was to estimate abundance through indices, to study the relationship between abundance-offer of hatchery (container with water), and to analyze the relationship between the presence of immature-material of the recipient. The survey was carried out in April 2015 in the city of Diamante. For the study were selected 64 blocks of the city, and of these, 89 dwelling, all at random. In each dwelling the open spaces were inspected and recorded all possible recipient of water, the type of material and if they possessed immature mosquitoes. Three indexes were calculated for the city: housing (IV), containers (IR) and Breteau (IB). Of the total number of dwelling surveyed, 81 dwelling had recipients, of which 473 recipients were found in total containers of water and 178 contained water, of which 15 had hatcheries. 65% of the recipients containing water were made of plastic, 22% glass, 7% metal and 6% other materials, of these recipients, 8 plastic, 3 glass and 4 other materials were breeding. The indices gave: 12.4 for IV, 8.99 for IR and 17.97 for IB. This study shows that the greater proportion of breeding sites in plastic and glass recipients would be contributing to the level of infestation found, responding to this marked offer of breeding sites for this mosquito. These containers were commonly used by the owners, but were in the open and had standing water. Greater control is essential in every home.
