AVALIAÇÃO DA APLICAÇÃO DE NOVOS MÉTODOS DE MONITORAMENTO POPULACIONAL NA VIGILÂNCIA ENTOMOLÓGICA EM DENGUE NO MUNICÍPIO DO IPOJUCA, PERNAMBUCO

Dengue is today the most important arbovirose of the world. The lack of sensitive indicators of population density and the lack of studies that determine the vector density threshold below which it can prevent the virus circulation DENV, demonstrate that much needs to be done to ensure effective protection against dengue and indicates the need for development of sensitive methods and easy operation to monitor the population of Aedes spp. This research has described the process of deploying a new pilot population monitoring method of vector of dengue in the city of Ipojuca, Pernambuco. The study was conducted in two urban areas of the municipality, Ipojuca, Porto de Galinhas and Headquarters during the period from February 2008 to July 2009. The continuous collection of eggs, through 150 ovitrampas in Ipojuca and 160 Headquarters in Porto de Galinhas, installed in two batches. The ovitrampa used involves two litres, treated with four drops of microbial larvicidal (Bti) and contains two straws as support for oviposition. The implementation of the pilot in the municipality method was feasible and through accession, dissemination and training of those involved in the deployment. The prior planning and the provision of minimum working conditions make the installation process as well as the feedback of the results to the environmental health Officer and residents relied on the sustainability of the method. The index of positivity of ovitrampas of Ipojuca Headquarters was 92.6% and of Porto de Galinhas, 100%. Indexes much higher than the detected by larval survey which did not exceed 5% in these localities, in the same period. The use of new monitoring method associated with information technology obtained are more viable and sensitive analysis, decision-making and priority setting.
