METHODS An 18-month longitudinal survey of infestation of Ae. aegypti immature stages was conducted for the 1015 residences (premises) of Vila Planalto, an area of Brasilia where the Breteau Index was about 40 before the study. This area was divided into five zones: a control zone with environmental management alone and four zones with insecticide treatment (methoprene, Bti, temephos). We tested for significant differences between infestation levels in the control and insecticide-treated areas, for relationships between climatic variables and larval indices, and to determine risk factors of infestation for certain types of premises and containers. RESULTS Environmental vector control strategies dramatically decreased infestation in the five areas. No significant differences could be detected between control strategies with insecticide and without. Some premises and container types were particularly suitable for breeding. The influence of climate on the emergence of Ae. aegypti adults for the area is described. CONCLUSION In a moderately infested area such as Brasilia, insecticides do not improve environmental vector control. Rather, infestations could be further reduced by focusing on residences and containers particularly at risk. The nature of the link between climate and larval population should be investigated in larger-scale studies before being used in forecasting models. specialized Aedes aegypti management strategies longitudinal survey breeding sites larval Stegomyia indices pupae 052 11 7 1104-1118 2006 1360-2276 https://www.documentation.ird.fr/hor/fdi:010035701 10.1111/j.1365-3156.2006.01653.x 1360-2276 [F B010035701] https://www.documentation.ird.fr/hor/fdi:010035701 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2025-01/010035701.pdf IRD - Base Horizon / Pleins textes 2006-08-30 2025-01-03 fdi:010035701 fre
