Summary:Natural plant products as larvicides could be considered as desirable alternatives to synthetic chemical insecticides for vector management. This study was undertaken to assess the mosquito larvicide activity of the essential oil from fresh leaves of against two medically important species of mosquito vectors. Essential oil was extracted by hydrodistillation and analyzed with gas chromatography and mass spectrometry (GC-MS). Fresh leaves of tree (500g) were collected in June 2014 from Tehran, Iran and was authenticated at the Department of Medical Entomology and Vector Control, School of Public Health, Tehran University of Medical Sciences, Tehran, Iran.In addition, the larvicidal potential of oil was evaluated against late-3 or young-4 instar larvae of and under laboratory condition. The mortality counts were made after 24h and LC and LC values were calculated. Forty-six components in leaves of were identified. The major components were α-Pinene (20.17%), 3-Carene (14%) and Cedrol (9.51%). The LC values against and larvae were 11.67ppm and 18.60ppm after 24h, respectively. oil could be considered as a natural larvicide for mosquito larval control.
