Abstract
In this study, temperature-sensitive microcapsules, Lemongrass oil (LemO)@diatomite (DE)@amino silicon oil (ASO)@polyethylene-polypropylene glycol (F127) (LemO@DEms), were effectively synthesized and characterized. Their microstructure, encapsulation efficiency, temperature-responsive release behavior, and toxicity against Reticulitermes flaviceps were thoroughly evaluated. The surface of LemO@DEms exhibited a porous morphology, achieving high encapsulation efficiency ranging from 60.64 % to 71.54 %. In vitro release analysis confirmed a sustained release profile of LemO from the microcapsules. Additionally, LemO@DEms maintained prolonged toxicity against R. flaviceps through a controlled release system responsive to temperature variations, highlighting its potential as a safe and natural insecticide alternative.
期刊介绍：
Industrial Crops and Products is an International Journal publishing academic and industrial research on industrial (defined as non-food/non-feed) crops and products. Papers concern both crop-oriented and bio-based materials from crops-oriented research, and should be of interest to an international audience, hypothesis driven, and where comparisons are made statistics performed.
