This study investigated the bioactivity of common ash (Fraxinus excelsior L.) and manna ornus leaf extracts, both in crude form incorporated into a biopolymer matrix, against spongy moth (Lymantria dispar larvae. Chemical analysis revealed that species were abundant polyphenolic compounds, with containing significant quantities p-hydroxycinnamic acid derivatives verbascoside, while was rich coumarins, particularly aesculetin aesculin. evaluated feeding deterrent activity, contact digestive toxicity, effects on larval nutritional indices, development. Chitosan–gelatin-based matrices extracts exhibited strong activity at all tested concentrations, showed moderate deterrence. The influenced behavior only after digestion, resulting reduced consumption growth, as well prolonged duration third instar. No toxicity observed for matrices. Incorporating chitosan–gelatin matrix significantly enhanced their larvae compared extracts. results suggest are promising environmentally friendly bioproducts forest insect control, offering an innovative approach to managing populations protecting ecosystems.
