title: Chemical Compositions of the Peel Essential Oil ofCitrus aurantiumand Its Natural Larvicidal Activity against the Malaria VectorAnopheles stephensi(Diptera: Culicidae) in Comparison withCitrus paradisi.
abstract: BACKGROUND
  Recently, essential oils and extracts derived from plants have received much interest as potential bio-active agents against mosquito vectors.
  
  
  METHODS
  The essential oils extract from fresh peel of ripe fruit ofCitrus aurantiumandCitrus paradisiwere tested against mosquito vectorAnopheles stephensi(Diptera: Culicidae) under laboratory condition. Then chemical composition of the essential oil ofC. aurantiumwas analyzed using gas chromatography-mass spectrometry (GC-MS).
  
  
  RESULTS
  The essential oils obtained fromC. aurantium, andC. paradisishowed good larviciding effect againstAn. stephensiwith LC50values 31.20 ppm and 35.71 ppm respectively. Clear dose response relationships were established with the highest dose of 80 ppm plant extract evoking almost 100% mortality. Twenty-one (98.62%) constituents in the leaf oil were identified. The main constituent of the leaf oil was Dl-limonene (94.81).
  
  
  CONCLUSIONS
  The results obtained from this study suggest that the limonene of peel essential oil ofC. aurantiumis promising as larvicide againstAn. stephensilarvae and could be useful in the search for new natural larvicidal compounds.
