摘要

本研究有效合成并表征了对温度敏感的微胶囊--香茅油（LemO）@硅藻土（DE）@氨基硅油（ASO）@聚乙烯-聚丙二醇（F127）（LemO@DEms）。对它们的微观结构、封装效率、温度响应释放行为以及对黄曲霉（Reticulitermes flaviceps）的毒性进行了全面评估。LemO@DEms 的表面呈现多孔形态，封装效率高达 60.64 % 至 71.54 %。体外释放分析证实了微胶囊中 LemO 的持续释放特性。此外，LemO@DEms 通过对温度变化做出反应的控释系统保持了对黄曲霉毒素的长期毒性，突出了其作为安全天然杀虫剂替代品的潜力。

Temperature-responsive microcapsule loaded with Lemongrass essential oil exhibit insecticidal activity against Reticulitermes flaviceps

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.
