Abstract

The study of larval fluctuations of Aedes aegypti, through entomological indicators (IE) define and reorient control actions. Such strategy, available in the surveillance and control program of Ae. aegypti allow to decrease the contact man-vector. The practical utility of housing index (IV), deposit index (ID) and Breteau index (IB) is evaluated with the occurrence of Dengue and Chikungunya cases, as well as determining the monthly fluctuation and differences between the three indexes, in the province of Orellana, Ecuadorian Amazon. Methods: This was a descriptive, field study and cross-sectional investigation. The indexes were obtained from the census and interventions made in housing inspections to 100% of the cases denounced during the epidemiological weeks 1-33 of 2015. The entomological indexes were analyzed from the averages and were compared according to cases, zones and months,through the analysis of variances, being adopted as level of significance "P" of values ​​lower than 0.05. Results: When the three indexes were associated with dengue cases, the difference was not statistically significant (P> 0.05). ID recorded the highest average among the neighborhoods that recognized between (n = 3-4) Chikunguya cases; so this difference was statistically significant (P <0.05). No statistical association was found between the occurrence of cases for both arbovirosis with the indexes and sectorization by zones carried out in the study. Both IB and IV reached the highest average in the month of April and lower average in January, being such a statistically significant difference (P <0.05). ID recorded the highest average in the month of May and the lowest average in January, being the correlation statistically significant (P <0.05). The ID could be a good predictor of Ae. aegypti in cases of CHIKV.

Keywords: evaluation, entomological indexes, Aedes aegypti, dengue, chikungunya.
