Insect Pest Control Strategies

Introduction: Aedes aegypti is a vector of several arboviruses that cause great concern for public health. In the state of Acre (Brazil), there are few studies related to A. aegypti, and none on the proliferation of the species in the state. The objective of this study was to estimate the rates of A. aegypti infestation in neighborhoods of the municipality of Rio Branco, Acre. Methods: ovitramps were installed in peridomestic environments, and the material found was sent to the laboratory for identification, counting and analysis of infestation rates. Results: 17,820 eggs of A. aegypti were captured, with a positivity index of 63.5% (POI); the neighborhoods Loteamento Joafra (92.8%), Laélia Alcantara (85.7%) and Morada do Sol (83.7%) had POIs greater than 80%. It was also observed that the mean egg density index (EDI) was 79.2 and that in the dry season there was greater oviposition with an EDI of 105.4, thus enabling the maintenance of the species in the environment. Conclusion: our data reveals that greater efforts are needed to control mosquitoes in the municipality of Rio Branco and thus prevent the spread of arboviruses of public health importance.
