Abstract

A research about population behaviour of Aedes aegypti (L.) in its larval phase, to explain their fluctuations through three entomological indexes and their relationships with dengue cases in Yurimaguas city, Loreto, Peru was performed. Positive housing were surveyed through three Entomological Indexes (EI) {Index of Domiciliary Infestation or Housing Index or also named Aedic Index (AI), Container Index (CI) or Breteu Index (BI)} and the kind of container more common in 11 zones of Yurimaguas city (5°53′30″ L.S; 76°05′26″ L.O), Loreto, Peru during 2000 to 2002. The three entomological indexes showed differences between all twelve evaluations performed during 2000 to 2002. In the three EI had observed a tendency to decrease from April-2000 to December-2002. AI decreased in 46.82 %; CI in 67.29 % and IB decreases in 43.71 %. The cases of dengue registered among 2000 to 2002 decreased 80.6 %. None differences between 11 zones in Yurimaguas for AI, CI and BI were observed. The three EI: AI, BI and CI all had highly lineal correlation and positive during all period 2000 to 2002. Only in AI and dengue cases, were found lineal correlation. In some evaluations among 2000 to 2002 existed significantly differences between ten categories of containers in CI and BI. Higher values for the next four categories: 10 (useless), 9 (flower pot and flower pot stand), 6 (rubber tyre), three (barrel, cylinder, sanson) were observed. The variations of EI during wet and dry periods were evaluated.
