title: [Effectiveness of insecticidal formulations for the Aedes aegypti adult population control in La Habana, Cuba].
abstract: BACKGROUND
  the vector control remains the sole sustainable measure to prevent dengue transmission in which the key role goes to adulticides in case of high rates of infestation by the vector, outbreaks or dengue epidemics. Pyrethroids are the most used whereas organophosphorous chloripirifos has been occasionally used because of the cost.
  
  
  OBJECTIVE
  to determine the effectiveness of insecticides in their commercial formulation that is applied today by the National Unit of Anti-Vector Control and Surveillance in Cuba for the control of Ae aegypti adults such as chlorpirifos (Terfos 48 CE) and pyrethroids, lambda-cyhalothrin (ICON 2.5 CE) and cypermethrin (Galgotrin 25 CE).
  
  
  METHODS
  fifteen Ae. Aegypti strains from the 15 municipalities of La Habana province, collected in 2008, and the Rockefeller reference strain were used. The level of effectiveness of these products against the adult vector was determined through WHO-recommended bioassays.
  
  
  RESULTS
  in situ effectiveness bioassays, Terphos 48 CE was the most effective in causing 100 % mortality of all the strains, followed by Icon 2.5 CE and Galgotrin 25 CE which reached 98 % and 100 % mortality rates respectively.
  
  
  CONCLUSIONS
  the field tests showed that the insecticides currently in use in the Aedes aegypti eradication program are still highly effective in La Habana province. The combined use of chlorpirifos and pyrethroids are recommended to delay the evolution of resistance to this last group of insecticides.
