AI Article Synopsis
- - Plant essential oils, like 1,8-cineole (1,8-CIN), are being explored as eco-friendly alternatives to chemical pesticides, but their release timing and duration need improvement for better effectiveness.
- - Researchers embedded 1,8-CIN in biodegradable cellulose acetate using electrospinning, resulting in a membrane that offers steady release and retains 21.74% of the oil after 42 days, showing improved release characteristics.
- - Application tests revealed that the membrane effectively killed test insects quickly, reduced their lifespan by 13.64%, and lowered oviposition rates by 23.35%, suggesting this approach can enhance pesticide efficiency and support sustainable pest management.
Article Abstract
Plant essential oils and their components have broad application prospects as substitutes for chemical pesticides. However, the burst release and persistence time need to be optimized. In this study, 1,8-cineole (1,8-CIN) was embedded in degradable cellulose acetate (CA) by electrospinning to achieve sustained release. The results showed that the sustained-release membrane had good morphology and thermal stability. The release test showed that the deficiency of the explosive release of 1,8-CIN improved after encapsulation, and 21.74 % of the drug remained after 42 days. In the application test, the fiber membrane could kill the test insects in a short period of time and affect the behavior choices of the test insects. It affected the growth and oviposition of the test insects and reduced adult longevity by 13.64 % and oviposition by 23.35 %. This study can improve the utilization rate of pesticides, alleviate environmental pressure, and provide new ideas for pest control.
