Evaluation of released malathion and spinosad from chitosan/alginate/gelatin capsules against larvae.

Efficacy of spinosad and malathion loaded in eco-friendly biodegradable formulations was evaluated for controlling larvae. Malathion (organophosphorus larvicide) and spinosad (naturally derived insecticide) were loaded on chitosan/alginate/gelatin capsules. Capsules were characterized by size measurement, scanning electron microscopy, Fourier transform infrared spectroscopy, and water uptake.
