“…Recently, the use of plant products received significant attention and proved to be alternative sources as parasitic control agents since -compared to synthetic products -they constitute a rich source of eco-friendly bioactive compounds. The plant extracts are suitable and safe alternatives due to their low toxicity to mammals and easy biodegradability [17,18]. Identifying novel effective mosquitocidal compounds are essential to overcome the increasing resistance rates of synthetic insecticide concern for the environment and food safety, the unacceptability of many chemicals insecticide [19].…”

Mosquito control remains a powerful method to control mosquito-transmitted diseases. Focusing on early stages is very important for many reasons because they are easy to handle, significantly affected by ambient environmental influences, natura.032.0l, and chemically toxic. The current study was aimed to examine the chemical components and larvicidal effect of Ethanolic extract of O. basilicum leaves and flowers on mosquito larvae. Fresh Ocimum basilicum was collected, dried in the shade for one week, and extracted with ethanol. The larvae were placed in plastic containers and bioassayed according to the protocol approved by WHO. After 24 hours of the recovery period, mortality percentage was recorded. Dead larvae were examined under a microscope to observe any morphological changes. The statistical analysis using SPSS program version 19 was done to determine Probit data. The phytochemical investigation of O. basilicum leaves presented many components such as flavonoids, glycosides, tannins, and steroids, whereas alkaloids, saponins, and terpenoids were absent. Moreover, O. basilicum flowers showed the presence of only tannins, terpenoids, steroids, and flavonoids, but not Saponins, glycosides alkaloids. The action of leaves and flower extracts were given LC50 values of 17.
