title: [Productivity of Aedes albopictus' breeding containers in Paraíba Valley, Brazil].
abstract: OBJECTIVE
  To estimate the potential productivity of artificial, permanent, and natural breeding containers of Aedes albopictus, potential vector species of dengue.
  
  
  METHODS
  Three locations were selected for this study: a) warehouse of disposable material goods in the urban area of Pindamonhangaba, state of São Paulo, Brazil; b) a small leisure farmland in Tremembé, state of São Paulo; and c) residual forest in the periurban area of Pindamonhangaba. All breeding containers were assessed and classified according to their water volume ( small (up to 1 liter), medium (over 1 but up to 10 liters), and large (over 10 liters), and type (artificial, natural, and permanent). Collections were carried out fortnightly for a period of 12 months, and a sample of fourth-instar larvae and pupae were collected from each container. Statistical analysis was performed using the Kriskal-Wallis test, t-Student test, and emergence estimate.
  
  
  RESULTS
  The statistical analyses and emergence estimate (E) showed that artificial large-size containers and permanent medium container were on average the most productive, resulting 2.8 females a day, each. Natural small and medium containers produced on average 0.5 and 0.6 females respectively.
  
  
  CONCLUSIONS
  There is a need for further studies on the potential productivity of containers not only of Ae. albopictus but also of Aedes aegypti, the main vector of dengue, which could contribute to better assessments of population densities in surveillance and control programs.
