| Abstract: | Botanical essential oils and their volatile constituents are increasingly recognized as environmentally safer alternatives to synthetic insecticides for managing stored-product pests. The adzuki bean beetle, Callosobruchus chinensis, is a cosmopolitan pest that causes substantial postharvest losses in legumes. In this study, nanoemulsions (NEs) of diallyl disulfide (a garlic-derived organosulfur compound), (R)-carvone (a spearmint-derived monoterpenoid), and their binary mixtures (1:1 and 2:1) were formulated using ultrasonication. The nanoemulsions consisted of spherical droplets (54-62 nm) and moderately high zeta potentials (-9.6 to -16.9 mV). Among treatments, diallyl disulfide NE exhibited the highest fumigant toxicity to C. chinensis, with an LC (Copyright © 2026 The Authors. Published by Elsevier Inc. All rights reserved.) |
