title: [Inhibitory effect of turpentine oil on Aedes aegypti (Diptera:Culicidae) larvae growth].
abstract: BACKGROUND
  in the fight for environmental protection, finding out alternative ways to control vectors that are important from the medical viewpoint is a must. Those plants having potent active principles and high chemical stability to act as pesticides can contribute to this end.
  
  
  OBJECTIVE
  to evaluate the possible inhibitory effect of photochemically-modified turpentine oil on Aedes aegypti larvae growth.
  
  
  METHODS
  Aedes aegypti larvae of an insecticide-sensitive strain from the insect breeding site located in the Institute of Tropical Medicine were used. During a week after the exposure to the lethal dose causing 90% mortality, the mortality indexes of larvae and pupas were recorded as well as the number of emerged adults and their sex in addition to adults stuck to the exuvias.
  
  
  RESULTS
  high larval and pupal mortality was observed in the survivors to the lethal dose causing 90% mortality after one week of the exposure; mortality index was 39.46%. Larvae which managed to grow to become adults amounted to 60.54% of the surviving larvae. Female to male ratio was very similar in the control whereas the exposed group showed a higher number of male adults. On estimating the hatching inhibition percentage, it got 36.47%.
  
  
  CONCLUSIONS
  the activity of turpentine oil as larvicide and Ae. aegypti growth inhibitor was demonstrated.
