Abstract
Control of mosquitoes and protection of people from their bites are of the most important ways to prevent diseases transmitted by them. Insects biting cause local symptoms (Itching, redness and burning) and can transmit the dangerous disease, especially in tropical regions. Repellents and especially herbal repellents are considered as appropriate methods to protect the people against mosquitoes biting. In the current study, repellent effect of extracts and essential oils of Melissa officinalis L., Rosmarinus officinalis L. and Lavandula angustifolia Mill. were evaluated against Anopheles stephensi in the laboratory and the effects were compared with those of synthetic repellent, N,N-Diethyl-3-methylbenzamide as a standard drug. Results of the statistical analysis revealed significant differences between oils and extracts (p < 0.01) against the tested species as oils were identified more effective than the extracts. Also the results showed that repellency effect of these materials in animals is higher compared to the human being.
