BACKGROUNDAs sex pheromones are environmentally friendly and specific, they are often used to monitor and control oriental fruit moths (OFMs). Currently, non‐biodegradable polymers are commonly employed as carriers to prepare controlled sex pheromone release systems for plant protection. Electrospinning is a relatively simple technique for preparing biodegradable nanofibers that allows for the controlled release of sex pheromones. This study aimed to develop a biodegradable controlled release system for the combination of OFM pheromone and codlemone via electrospinning, in which codlemone was used as a synergist for OFM pheromone.RESULTSNew systems for the controlled release of combined pheromones from OFM and colding moths were developed using electrospun nanofibers from polycaprolactone (PCL), cellulose acetate (CA), and polylactic acid (PLA). In the indoor experiments, the load ratio and release stability of CA nanofibers loaded with combined pheromones (CA‐SP) were superior to those of the other two nanofiber types. In the field experiments, among all the treatments, 10 mg of CA‐SP was the most attractive to OFMs, and its effective duration was approximately 6 weeks. The optimum storage temperature for all nanofibers was −20 °C.CONCLUSIONElectrospun CA‐SP nanofibers were biodegradable and environmentally friendly, with stable release. This study presents a new technique that could be beneficial for the monitoring and control of OFMs. © 2025 Society of Chemical Industry.

静电纺丝纳米纤维作为 Grapholita molesta 和 Cydia pomonella 组合信息素的控释系统



背景性信息素是环保且具有特异性的,它们通常用于监测和控制东方果蛾 (OFM)。目前,不可生物降解的聚合物通常用作载体来制备用于植物保护的受控性信息素释放系统。静电纺丝是一种相对简单的制备可生物降解纳米纤维的技术,可以控制性信息素的释放。本研究旨在通过静电纺丝开发一种可生物降解的控释系统,用于 OFM 信息素和钴酮的组合,其中钴酮用作 OFM 信息素的增效剂。结果使用聚己内酯 (PCL) 、醋酸纤维素 (CA) 和聚乳酸 (PLA) 的静电纺丝纳米纤维开发了用于控制 OFM 和冷蛾联合信息素释放的新系统。在室内实验中,负载组合信息素 (CA-SP) 的 CA 纳米纤维的负载比和释放稳定性优于其他两种纳米纤维类型。在田间实验中,在所有处理中,10 mg CA-SP 对 OFMs 最有吸引力,其有效持续时间约为 6 周。结论电子喷枪 CA-SP 纳米纤维具有可生物降解、环保、释放稳定的特点。本研究提出了一种可能有助于监测和控制 OFM 的新技术。© 2025 化工学会.
