title: [Seasonal and time dynamics of Aedes aegypti (Diptera: Culicidae) in Cienfuegos municipality].
abstract: BACKGROUND
  dengue is one of the most important vector-borne diseases in Las Americas due, among other factors, to the increase of Aedes aegypti populations.
  
  
  OBJECTIVE
  to ascertain the space and time behaviour of Ae. aegypti in Cienfuegos municipality from 2006 to 2008.
  
  
  METHODS
  the study was conducted in Cienfuegos municipality located on the central south part of Cuba. Larvae and adult mosquitoes were collected throughout the municipality in the 2006-2008 period using the methodology of the national dengue vector eradication program.
  
  
  RESULTS
  twelve mosquito species were found; Culex quinquefasciatus, Ochlerotatus taeniorhynchus, Gymnometopa mediovittata and Aedes aegypti were the most abundant. The containers showing the highest positivity to Ae. aegypti presence were water tanks on the ground, various reservoirs, and larvitraps; the highest positive indexes were reported in August through November. The highest amounts of adult mosquitoes were captured in July through October. Of the 2 methods, capture at rest was more effective in collecting more adult mosquitoes with 134 (96.41%), 30 (96.78%) and 27 (100%), respectively and highly significant difference, p < 0.0001. According to the entomological stratification of the areas in the municipality, the areas 2 and 3 must be classified as high risk, the areas 1 and 5 as mild risk and the rest of the areas as low risk areas.
  
  
  CONCLUSIONS
  it is of vital importance to be permanently on the alert because Aedes aegypti is present throughout the year in the Cienfuegos municipality.
