摘要
最近，精油（EOs）封装技术在农业和农业食品领域的应用越来越广泛。据报道，封装是一种安全的环保技术，可减少传统杀虫剂的使用。本研究评估了包裹在两种环糊精 β-CD 和 HP-β-CD 中的麝香石竹环氧乙烷对枣树夜蛾幼虫的熏蒸毒性和持久性。研究了两种包合复合物的保留能力、封装效果、负载能力和释放行为。结果表明，所研究的两种 CD 具有重要的保留能力。此外，包裹在 CD 中会延迟迷迭香环氧乙烷生物活性成分的释放，这就解释了包裹在 CD 中的迷迭香环氧乙烷对陶瓷虫第五龄幼虫的有效性。此外，在两种光盘中封装迷迭香环氧乙烷提高了杀虫毒性的持久性。这项研究支持在红枣产业中使用环糊精（主要是 HP-β-CD）来控制害虫。
Potential of cyclodextrin-based formulations of Rosmarinus officinalis essential oils in the control of the date moth Ectomyelois ceratoniae (Pyralidae).
Recently essential oils (EOs) encapsulation is experiencing growing applications in agricultural and agri-food sector. Encapsulation is reported as safe environmental technology leading to a reduction of conventional insecticides use. This study concerns the assessment of fumigant toxicity and persistence of Rosmarinus officinalis EO encapsulated in two cyclodextrins β-CD and HP-β-CD against larvae of the date moth, Ectomyelois ceratoniae. The retention capacity, encapsulation efficacy, loading capacity and release behavior of the two inclusion complexes were investigated. Results showed that two studied CDs had in important retention capacity. Additionally, the encapsulation within CDs delayed the release of rosemary EO bioactive components; which explains the effectiveness of the encapsulated rosemary EO in CDs against E. ceratoniae fifth instars larvae. Furthermore, the encapsulation in the two CDs improved the persistence of the insecticidal toxicity. This study supports the use of cyclodextrins, mainly HP-β-CD, in the date industry for the control of insect pests.
期刊介绍：
International Journal of Environmental Health Research ( IJEHR ) is devoted to the rapid publication of research in environmental health, acting as a link between the diverse research communities and practitioners in environmental health. Published articles encompass original research papers, technical notes and review articles. IJEHR publishes articles on all aspects of the interaction between the environment and human health. This interaction can broadly be divided into three areas: the natural environment and health – health implications and monitoring of air, water and soil pollutants and pollution and health improvements and air, water and soil quality standards; the built environment and health – occupational health and safety, exposure limits, monitoring and control of pollutants in the workplace, and standards of health; and communicable diseases – disease spread, control and prevention, food hygiene and control, and health aspects of rodents and insects. IJEHR is published in association with the International Federation of Environmental Health and includes news from the Federation of international meetings, courses and environmental health issues.
