Objectives: To determine the phytochemical screening and major phytocompounds from Indigofera tinctoria leaf methanol extract as well as ovicidal and larvicidal toxicity towards medical and agronomic pests, Aedes aegypti, Culex quinquefasciatus, Spodoptera litura and Helicoverpa armigera. Methods: In this study, the phytochemical screening was done by prescribed method, finding of phyto-constituents were made by GC-MS analysis, ovicidal and larvicidal toxicity of selected pests were recorded after 24 hrs. post treatment at various concentrations. The mortality was assessed by using probit analysis to calculate LC 50 /LC 90 . Findings: By the phytochemical screening, the more numbers of phytochemicals were obtained from methanol extract as well as GC-MS analysis displayed sum of 10 phyto-compounds gained 100% besides two phyto-compounds were major constituents Heptasiloxane, hexadecamethyl-and 1,1-Dimethylethyl 3-Phenyl-2-Propenoate. The phytoproducts of I. tinctoria were produced maximum eggs toxicity around 100% at higher concentration. Similarly, I. tinctoria leaf methanol extract borne major phyto-compounds major constituents Heptasiloxane, hexadecamethyland 1,1-Dimethylethyl 3-Phenyl-2-Propenoate were tested 3 rd instar larvae of selected medicinal and agronomic pests with their LC 50 / LC 90 value were 10.93/18.65 µg/ml, 10.87/18.77 µg/ml, 15.29/27.17 µg/ml, 16.84/29.41µg/ml and 11.16/19.38 µg/ml, 10.43/18.51 µg/ml, 14.57/26.58 µg/ml and 15.61/28.63 µg/ml were recorded on various pests of Ae. aegypti, Cx. quinquefasciatus and S. litura and H. armigera, respectively. Novelty: The statistical analysis of the data clearly indicates that phyto-compounds of I. tinctoria induced outstanding larval https://www.indjst.org/

“…Application of synthetic larvicides in aquatic ecosystems may cause harmful effects on human beings and many other non-target organisms. In search of alternative pesticides many investigators have explored the beneficial role of plant extracts, plant compounds, actinomycetes sea weeds and mushroom extracts against mosquito larvae (Campbell and Sullivan, 1993;Thangam and Kathiresan, 1994;Pandey et al, 2007;Nazar et al, 2009;Ganesan et al, 2018;Darvin et al, 2019;Sivanandhan et al, 2019;Monisha et al 2020). Many essential oils showed good larvicidal activities against mosquito species and are reported as environmentally safe insecticides (Corbet et al, 1995;Pitasawat et al, 2007).…”

Mosquitoes occupy the first place among the most dangerous insects in the world, because they kill more than five lakhs people every year around the world by transmitting lethal pathogens. People use many methods and devices to combat the mosquito problem. Chemical pesticides are commonly used to control mosquitoes and their bites around the world. Since the last two decades public has started to avoid the use of synthetic chemicals for mosquito management due to their harmful effects on environment and human health. Pesticide resistance in mosquitoes is a major side effect of synthetic chemical applications. Volatile oils or essential oils obtained from green plants are considered as reliable alternatives for mosquito management. Several hundred volatile oils and volatile compounds have been tested against eggs, larva, pupa and adults of various vector mosquito species. Oils, extracts and powders of leaf, flowers and bark of many aromatic plants are being used as mosquito repellents in many countries for many centuries. Scientific validation of biological activities of several botanicals has been intensified in the last three decades and several herbal mosquito control products have been commercialized. The aim of the present review article is to provide up-to-date information on biological activities of plant volatile oils and volatile compounds against vector mosquitoes and to highlight the promising volatile compounds for the development of new herbal mosquito control products.
