Gum Arabic containing Allium sativum L. essential oil-based nanoparticles as biofumigant grain protectant against Callosobruchus maculatus F.

ABSTRACT: Gum Arabic nanoparticles (GA NPs) were used to nano-encapsulate Allium sativum or garlic essential oil (GO) using the freeze-drying technique. The fumigant toxicity of GO and GO-GA nanoparticles was evaluated against Callosobruchus maculatus, a major pest of stored products. Adults were exposed to concentrations of 10.0, 5.0, 2.5, and 1.25 µL/L air for 24 hours to evaluate the lethal concentration (LC) values. Gas Chromatography-Mass Spectrometry for GO identified diallyl trisulfide (38.78%), allyl methyl trisulfide (23.93%), and diallyl disulfide (13.66%) as the main compounds. Dynamic light scattering and transmission electron microscope tests verified the stability and uniformity of the produced nanoparticles, which were distinguished by their small particle size (15.10 nm), low PDI val
