Antifeeding and Insecticide Properties of Aqueous and Ethanolic Fruit Extracts from Melia azedarach L.on the Elm Leaf Beetle Xanthogaleruca luteola Müller

Xanthogaleruca luteola Müller (Coleoptera: Chrysomelidae), a defoliator of Ulmus species currently present in several regions of central Chile, causes severe damage to trees, mainly in park areas, street tree-lines and gardens. The antifeeding and insecticidal activities of extracts from immature fr...
