The productivity of vegetable crops is constrained by insect pests. The search for alternative insect pest control is becoming increasingly important and is including the use of plant-derived pesticides. Plant-derived pesticides are reported as effective in controlling various insect pests through natural mechanisms, with biodegradable organic materials, diverse bioactivity, and low toxicity to non-target organisms. An antifeedant approach for insect control in crop management has been comprehensively studied by many researchers, though it has only been restricted to plant-based compounds and to the laboratory level at least. Nano-delivery formulations of biopesticides offer a wide variety of benefits, including increased effectiveness and efficiency (well-dispersion, wettability, and target delivery) with the improved properties of the antifeedant. This review paper evaluates the role of the nano-delivery system in antifeedant obtained from various plant extracts. The evaluation includes the research progress of antifeedant-based nano-delivery systems and the bioactivity performances of different types of nano-carrier formulations against various insect pests. An antifeedant nano-delivery system can increase their bioactivities, such as increasing sublethal bioactivity or reducing toxicity levels in both crude extracts/essential oils (EOs) and pure compounds. However, the plant-based antifeedant requires nanotechnological development to improve the nano-delivery systems regarding properties related to the bioactive functionality and the target site of insect pests. It is highlighted that the formulation of plant extracts creates a forthcoming insight for a field-scale application of this nano-delivery antifeedant due to the possible economic production process.
蔬菜作物的产量受到害虫的限制。寻找替代的害虫防治方法变得越来越重要，其中包括使用植物源农药。据报道，植物源农药通过自然机制对控制各种害虫有效，具有可生物降解的有机材料、多样的生物活性以及对非目标生物的低毒性。许多研究人员对作物管理中采用拒食剂方法防治害虫进行了全面研究，但至少目前仅限于基于植物的化合物且仅在实验室层面。生物农药的纳米递送制剂具有多种益处，包括提高有效性和效率（良好的分散性、润湿性和靶向递送）以及改善拒食剂的性能。这篇综述论文评估了纳米递送系统在从各种植物提取物中获得的拒食剂中的作用。评估内容包括基于拒食剂的纳米递送系统的研究进展以及不同类型纳米载体制剂对各种害虫的生物活性表现。拒食剂纳米递送系统可以提高其生物活性，例如提高亚致死生物活性或降低粗提物/精油（EOs）和纯化合物中的毒性水平。然而，基于植物的拒食剂需要纳米技术的发展来改进纳米递送系统，以改善与生物活性功能和害虫靶位点相关的性能。需要强调的是，由于可能的经济生产过程，植物提取物的制剂为这种纳米递送拒食剂的田间规模应用提供了一个未来的发展方向。
