o:7923 DEVELOPMENT OF A BIOPOLYMER-BASED BIOPESTICIDE WITH AILANTHUS ALTISSIMA EXTRACT FOR SUSTAINABLE CONTROL OF LYMANTRIA DISPAR IN FOREST ECOSYSTEMS en This work presents the development of a novel biopesticide formulation based on natural biopolymers (chitosan and gelatin) and plant extract from the invasive species Ailanthus altissima. The use of this extract is economically and environmentally justified, as it supports sustainability by utilizing a widespread weed. A key challenge with plant-based biopesticides is the instability of active compounds when exposed to environmental factors. This was overcome by incorporating the extract into a chitosan-gelatin biopolymer matrix, both of which are GRAS (Generally Recognized as Safe)-certified by the FDA (Food and Drug Administration). The resulting formulation enables controlled release and prolonged activity of the bioactive compounds. Laboratory testing against the spongy moth (Lymantria dispar L.) showed improved efficacy compared to the pure extract. Since A. altissima extract is not commercially available and such a formulation has not been previously tested for spongy moth control, this approach offers an innovative, non-toxic, and eco-friendly alternative with great potential for forest pest management. 1552100 978-86-80109-27-5 91552100 170258441 2025-06-30T11:23:59.918Z 44 no 46 Jelena Jovanović University of Belgrade-Institute for Multidisciplinary Research, Belgrade, Serbia; Center of Excellence for Green Technologies, University of Belgrade, Institute for Multidisciplinary Research, Belgrade 46 Zorica Branković University of Belgrade-Institute for Multidisciplinary Research, Belgrade, Serbia; Center of Excellence for Green Technologies, University of Belgrade, Institute for Multidisciplinary Research, Belgrade 46 Jovana Ćirković University of Belgrade-Institute for Multidisciplinary Research, Belgrade 46 Aleksandar Radojković University of Belgrade-Institute for Multidisciplinary Research, Belgrade, Serbia; Center of Excellence for Green Technologies, University of Belgrade, Institute for Multidisciplinary Research, Belgrade 46 Sanja Perać University of Belgrade-Institute for Multidisciplinary Research, Belgrade 46 Slobodan Milanović University of Belgrade, Faculty of Forestry, Belgrade, Serbia; Mendel University in Brno, Faculty of Forestry and Wood Technology, Brno, Czech Republic 46 Jovan Dobrosavljević University of Belgrade, Faculty of Forestry, Belgrade, Serbia 46 Ivan Milenković University of Belgrade, Faculty of Forestry, Belgrade, Serbia; Mendel University in Brno, Faculty of Forestry and Wood Technology, Brno, Czech Republic 46 Nemanja Simović University of Belgrade, Faculty of Forestry, Belgrade, Serbia 46 Vanja Tadić Institute for Medicinal Plants Research “Dr. Josif Pančić”, Belgrade, Serbia 0000-0003-1761-604X 46 Ana Žugić Institute for Medicinal Plants Research “Dr. Josif Pančić”, Belgrade, Serbia 0000-0002-7722-6169 46 Goran Branković University of Belgrade-Institute for Multidisciplinary Research, Belgrade, Serbia; Center of Excellence for Green Technologies, University of Belgrade, Institute for Multidisciplinary Research, Belgrade, Serbia application/pdf 753971 https://unilib.phaidrabg.rs/o:7923 no yes 1 70 92000004 71A10 BOOK OF ABSTRACTS 8th Conference of the Serbian Society for Ceramic Materials 8th Conference of The Serbian Society for Ceramic Materials 2025
