本研究的目的是制备和表征含有花椒果实精油的聚-ε-己内酯（PCL）纳米球，并评价其稳定性以及对烟粉虱（Bemisia tabaci）的杀虫和忌避活性。PCL纳米球表现出均匀的球形形态，粒径在106.7 nm和129.2 nm之间，pH约为6，zeta电位（ZP）低于-19.0 mV，包封率高于98%。只有43%的nanocapsulated精油（NSEO）降解响应紫外线，而精油（EO）降解了76%，在同一时期。在自由选择测试中，NSEO和EO将粉虱卵的数量减少了约70%。1.5%的NSEO和EO对烟粉虱2龄幼虫的致死率分别为82.87%和91.23%。虽然NSEO显示出较低的杀虫活性，但由于聚合物赋予的抗光降解保护作用，它比游离EO具有更大的优势。因此，它的使用可以通过光保护和控制释放来优化精油在田间的维护。结果表明，Z.利多卡因果实可用于B。尽管如此，需要在实地一级进一步评价NSEO的惠益。
The aim of our study was to produce and characterize poly-ε-caprolactone (PCL) nanospheres containing essential oils from Zanthoxylum riedelianum fruit and to evaluate their stability gains as well as their insecticidal and deterrent activities against whitefly (Bemisia tabaci). The PCL nanospheres exhibited a homogeneous spherical morphology, with particle diameters between 106.7 nm and 129.2 nm, pH of approximately 6, zeta potential (ZP) lower than −19.0 mV and encapsulation efficiency higher than 98%. Only 43% of the nanoencapsulated essential oil (NSEO) was degraded in response to ultraviolet light, whereas the essential oil (EO) degraded by 76% over the same period. In a free-choice test, the NSEO and EO reduced the number of whitefly eggs by approximately 70%. NSEO and EO at 1.5% killed 82.87% and 91.23% of 2nd-instar nymphs of whitefly, respectively. Although NSEO displayed lower insecticidal activity, it offers a greater advantage over the free EO, due to protection conferred by polymer against photodegradation. Therefore, its usage may optimize the maintenance of essential oils in the field through photoprotection and controlled release. Our results suggest that the EO of Z. riedelianum fruit can be used for B. tabaci management strategy; nevertheless, the benefits of NSEO require further evaluation at the field level.
