Abstract

Mosquitoes control, especially through the use of natural products, seems to be an urgent priority. In the current study, efficacy of some of these natural products such as plants extracts, organic acids, and plant oils, in monitoring to check their larvicidal effect, were evaluated by their application on 4th stage larvae of Culex pipiens. For plant methanol extracts; ginger, followed by garlic, showed the highest effect while onion showed the lowest efficacy. The lowest effect was found for peppermint in the oils used the highest for clove oil. Whereas, organic acids have a great effect on 4th stage larvae; citric acid has a higher effect at the concentration of 1.2 ml/100ml than acetic acid. Used materials are related to concentration and time. This research shows promising results in the use of natural products as larvicidal agents for mosquitoes, and further studies are required to examine others
