title: Laboratory Evaluation of Temephos againstAnopheles stephensiandCulex pipiensLarvae in Iran.
abstract: BACKGROUND
  Malaria is still a health problem in Iran. There are several vector control activities, including Indoor Residual spraying, using insecticide treated nets and larviciding including Temephos. In addition nuisance mosquitos are prevalent in the urban areas. So that evaluation of this species to larvicide will provide a clue for management of vector control activities.
  
  
  METHODS
  Two mosquito species were used in this study:Anopheles stephensiwere collected from Kazeroun andCulex pipiensfrom Tehran, capital of Iran. All the tests were carried out according to the WHO method. All the test kis was provided by WHO.
  
  
  RESULTS
  Results showed a LC50= 0.0523 and LC90=0.3822 mg/l forAn. stephensi. The figure forCx. pipienswas 0.1838 and 0.8505 mg/l respectively.
  
  
  CONCLUSIONS
  monitoring of insecticide resistance to Temephos should be evaluated regularly for management of vector control.
