Abstract

A new delivery system was applied to control P. operculella based on interpolation of Lippia citriodora essential oil into PVA-nanofiber using electrospinning technique. Based on GC-MS results, geranial and (-)-spathulenol were the prevailing compounds of the essential oil. Fumigant bioassay revealed that nano-formulated essential oil was more toxic than L. citriodora pure one. The results of the durability test showed that PVA-EO nanofibers were highly durable compared to the pure essential oils: their durability was approximately 3.5 times greater. This study indicated that these novel systems could be used in IPM program for the control of stored product pests.

摘要

采用静电纺丝技术将柠檬百合精油内插到 PVA 纳米纤维中，应用一种新的递送系统来控制P. operculella 。根据 GC-MS 结果，香叶醛和 (-)-spathulenol 是精油的主要化合物。熏蒸剂生物测定表明，纳米配方的精油比L. citriodora纯精油毒性更大。耐久性测试的结果表明，与纯精油相比，PVA-EO 纳米纤维具有高度的耐久性：它们的耐久性大约高出 3.5 倍。该研究表明，这些新系统可用于 IPM 计划，以控制储存产品害虫。
