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