Comparação de técnicas de monitoramento vetorial de Aedes aegypti e sua correlação com fatores climáticos e ambientais

Abstract

The circulation of multiple viruses transmitted by Aedesaegypti and the absence of vaccines represents a worrying scenario, greatly increasing the need to seek successful strategies in mosquito control. The levels of vector infestation associated with viral circulation confirm the need for monitoring as an important surveillance tool because of the demonstrated ability to indicate risk of epidemic. Therefore, the present work has proposed to evaluate comparatively the Rapid Survey of the Infestation Index by Ae. aegypti (LIRAa) and Ovitraps associating climatic factors with vector density in the city of João Pessoa, PB - Brazil in two neighborhoods: Planalto da Boa Esperança (PBE) and Cabo Branco that present different sociodemographic and environmental realities. In the period of 2017, ovitraps were applied in the two neighborhoods and the data obtained were compared with the LIRAa performed in January, April, July and October. In this study it was possible to identify that ovitraps had a higher sensitivity than LIRAa. The Cabo Branco neighborhood had the lowest rates of PBE, and in both neighborhoods, the most important species was Ae.aegypti, Ae albopictus was found only in the neighborhood of Cabo Branco. Climatic conditions such as precipitation and temperature interfere with the rate of infestation. The data presented in this research provide qualified information for the performance and execution of prevention and control actions, allowing the mobilization of other sectors, besides health secretariats, such as urban cleaning services and water supply to try to reduce infestation rates and consequently, the chance of acquiring arboviruses.
