The focus of the study is to determine the Effectiveness of Individual and Combined Concentrations from the Ethanolic leaf extracts of Rosa hybrid (Rose), Vitis vinifera (Grapevine) and Coriandrum sativum (Cilantro) as an insecticide, in a spray formula. This study utilizes the use of home-grown plants, particularly Rosa hybrid , Vitis vinifera, and Coriandrum sativum as an alternative to commercially available insecticide. The use of varying concentrations of this, particularly the leaf extracts, will be used. The study will also make use of Culex quinquefasciatus (Southern House Mosquito) as the representative species. The determination of the capabilities of the extracts as insecticide in killing Culex quinquefasciatus is the aim of the researchers in order to utilize and identify which extract has the best concentration in killing mosquitoes. The researchers will not be focusing on the phytochemical constituents of the said plants. The study will not be utilizing Aedes aegypti as the study’s representative species. The researchers will not be utilizing other means in eradicating mosquitoes like tablets, repellents, lotions and etc. rather than the use of spray formula as the final product.
