چکیده
Cupressus sempervirens essential oil was used to evaluate the efficiency of excito-repellency activity against Anopheles stephensi Liston, (Diptera: Culicidae). C. sempervirens essential oil was used at different concentrations of 25, 50 and 75% (v/v) and the mosquitoes were exposed for an hour. The compound showed 50.5± 2.8, 65.3± 3.1 and 77± 3.9% entry to exit-trap at 25%, 50% and 75% (v/v), respectively. In addition, the mean blood feeding rates for the above concentrations were 11.3, 7.1 and 3 percent. Moreover, survival rates were 49.4± 2.9%, 34.6±3.9% and 23±4.1. At 75% C. sempervirens was more effective than other concentrations in terms of irritability. Similarly, it was revealed that concentration of 25% was less effective. These studies indicated that the populations of malaria vectors can be effectively controlled using C. sempervirens treated bed nets. It seems to be a promising compound for personal protection against An. stephensi.
