چکیده
BACKGROUND Protecting the environment from chemical hazards of synthetic insecticides along with offering of new breeding areas for vectors by urbanization indicate the trial of natural insecticides. METHODS The acetone extracts of Anethum graveolens, Ocimum basilicum and Thymus vulgaris were tested for their insecticidal effect on Culex pipiens adults and larvae in different concentrations depending on the technique used. RESULTS The extracts were significantly effective in all models used with basil being the best in all tested three techniques (LC50= 0.064) in larval feeding, (LC50= 0.330) in CDC bottle assay and (LC50= 13.148) in adults feeding (P< 0.05). CONCLUSION The results recommend the eco-friendly studied extracts as candidates for controlling Cx. pipiens the lymphatic filariasis vector.
