Prospective of Green waste compounds against Dengue vector Aedes aegypti and Filariasis vector Culex quinquefasciatus

One of the main objectives of Sustainable development goals (SDGs) is to prevent the environment and public health by substantially reducing waste generation through prevention, reduction, recycling, and reuse by 2030. Another current concern is the overuse and misuse of synthetic larvicides which are the primary drivers in the burgeoning of insecticide-resistant vector species. Eutrophic water, lack of sanitation, inadequate infection prevention and control promote the spread of these vectors that are responsible for various severe diseases like Malaria, Dengue, Chikungunya, Filariasis, etc. Mosquito species not responding to synthetic larvicides have developed resistance to them and the changing environment and is. an alarming situation if the proliferation is not regulated. The green waste comprising leaves, grass, flowers,, non-woody plants,, etc. containing high amount of lignocellulosic material. They can be converted into mulch in a short period. Following the investigations, we examine the natural products as larvicides. Green waste collected and segregated belonged to several families. They were extracted with two solvents and their larvicidal activities were observed on two most common mosquito species viz; Ae.aegypti and C.quinquefasciatus. The plant materials extracted with solvents manifest various degrees of larvicidal activities, the most promising results were drawn for acetone extracts of Alastonia scholaris against Cx. quinquefasciatus (LC50=1.76 mg/L, LC90=3.89 mg/L). For Ae.aegypti the best results were drawn from Ethyl acetate extracts of Azadirachta indica (LC50 = 1.91 mg/L, LC90 = 3.96 mg/L). Green waste is one of the best alternatives to synthetic larvicides as well as an innovative way to induce SDGs.
