Abstract
This study aimed to test the oviposition deterrent effect and repellent from bites for five essential oils (Hyacinthus orientalis L., Cinnamomum camphora L., Rosmarinus officinalis L., Laurus nobilis L.and Ruta graveolens L.) at four concentrations (200, 100, 50, 25 ppm) against the female of Culex pipiens molestus Forskal. Results indicated that essential oils of all plants showed oviposition deterrent, the essential oils of H. orientalis, C.camphora and R.officinalis caused 100% deterrent at concentrations (200 and 100 ppm ), but oil of R. graveolens caused low deterrent to the female. Where the rate of deterrent reached 74% at concentration 200 ppm. The essential oils of plants showed repellent bites of female, H.orientalis caused the best protection period so reached (160.0 ± 20.4 ) minute, followed C. camphora , R. officinalis, L. nobilis and R. graveolens, where caused protection period (130 ± 14.0 , 90 ±16.4 , 70 ± 15.3 ,50 ± 19.2 ) minute respectively.
