From waste to resource: Garlic peel‐derived proteases (Allium sativum) for nematode control
Environmental Progress &Sustainable Energy, Volume 44, Issue 4, July/August 2025.Abstract This study aimed to prepare a protease‐rich extract from garlic peel (Allium sativum) and evaluate its nematicidal potential. The garlic peel was crushed, suspended in distilled water, and the obtained extract was subjected to filtration, centrifugation, and dialysis to concentrate the proteases. The nematicidal activity was tested in vitro on

Entomologia Experimentalis et Applicata, Volume 173, Issue 7, Page 708-723, July 2025.We investigated the molecular basis of host switching by the phytophagous West Indian fruit fly (A. obliqua). Third‐instar larvae showed differential gene expression according to host plants: red mombin, mango, and carambola. The main gene categories differentially expressed were digestion, detoxification, and gene regulators.
