| Abstract | ||
| Laboratory experiments were conducted at the National Malaria Centre, Sinnar State, Sudan, to test the efficacy of hexane extracts of rehan leaves (Ocimum basilicum) used as paper impregnation, against adult mosquito Anopheles arabiensis Patton. Repellency every 30 minutes, oviposition deterrency and adult mortality after 24 hours exposure were calculated using an excito-repellency box recommended by the WHO. Results indicated that rehan hexane extract at 10% concentration exhibited repellency property to the tested mosquitoes up to 2 hours, and it was superior to the standard insecticide. However all tested concentrations (1%, 5%, 10%) depicted oviposition deterrency to the insect, but had a little insecticidal effect compared to the standard. | ||
