N2 - Biopesticides are eco-friendly solutions because they have low toxicity and specific targets. Neem oil (Azadirachta indica) has the potential to enhance the antifeedant properties of wood vinegar against insect pests. Therefore, this study aims to evaluate a nanoemulsion mixture of neem oil and wood vinegar viz-a-viz their characteristics and efficacy against polyphagous insects like Spodoptera litura. This formulation involved the mixture of wood vinegar and various concentrations of neem seed oil (10, 20, 30, and 40 %), alongside surfactant, and water, to form an oil-in-water (o/w) nanoemulsion. Furthermore, the formulations were then studied for their physicochemical properties and bioactivity. However, the 30 % formulation showed the best characteristics at 33.78 nm droplet size, with a polydispersity index and an antifeedant activity of 0.176 and 90.4%, respectively. The best activity (98.6%) was observed in the combination of 40 % neem oil and 2 % tar.
