Characterization of the spatial and temporal dynamics of the dengue vector population established in urban areas of Fernando de Noronha, a Brazilian oceanic island.

摘要: Aedes aegypti has played a major role in the dramatic expansion of dengue worldwide. The failure control programs reducing rhythm global through vector suggests need for studies to support more appropriated strategies. We report here results longitudinal study on Ae. population dynamics continuous egg sampling aiming characterize infestation urban areas Brazilian oceanic island, Fernando de Noronha. spatial and temporal distribution island was described using monitoring system (SMCP-Aedes) based 103-trap network sampling, GIS statistics analysis tools. Mean densities were estimated over 29-month period starting 2011 producing monthly maps mosquito abundance. detected oviposition most traps. high positive ovitrap index (POI=83.7% 2815 events) indicated frequent presence blood-fed-egg laying females at every station. Egg density (eggs/ovitrap/month) reached peak values 297.3 (0 - 2020) May 295 2140) August 2012. stable established throughout inhabited demonstrated. A strong association between abundance rainfall with 2-month lag observed, which combined first-order autocorrelation observed series counts can provide an important forecasting tool. This first description characteristics by provides baseline information analyze relationships cases, development integrated
