Nanopesticides with antiwashing capacity on leaves are the most promising new approaches for sustainable pest management and have been fully evaluated in the laboratory. However, few studies have tested these nanopesticides on pests, and their efficacy under field conditions has not been investigated. In this study, an adhesive hollow mesoporous silica hybrid with well-defined spherical shape and good monodispersity was used as a nanocarrier of cyantraniliprole (CNAP) to fabricate an adhesive nanopesticide (CNAP-HMS-PDAAM). The control efficacy of CNAP-HMS-PDAAM was tested under field conditions. The results indicated that the efficacy of four doses of CNAP-HMS-PDAAM (30.0–69.0 g a.i./ha) against Cnaphalocrocis medinalis (Guénee) 3, 7, and 14 days after spraying did not significantly differ from that of Benevia (34.5 g a.i./ha). Twenty-eight days after spraying, the efficacy of all four doses of CNAP-HMS-PDAAM was significantly better than that of Benevia. Additionally, the efficacy of CNAP-HMS-PDAAM at doses of 34.5, 39.0 and 69.0 g a.i./ha against Chilo suppressalis (Walker) were significantly higher than that of Benevia (34.5 g a.i./ha). Thus, CNAP-HMS-PDAAM showed long-term control efficacies against C. medinalis (Guénee) and C. suppressalis (Walker), mainly due to its strong adhesive property on rice leaves and its sustained release properties. In addition, the nanocarriers showed good biocompatibility and had no obvious influence on the growth of rice.

在叶子上具有抗洗涤能力的纳米农药是可持续有害生物管理的最有希望的新方法，并且已经在实验室中进行了全面评估。但是，很少有研究测试过这些纳米农药对害虫的作用，尚未对它们在田间条件下的功效进行研究。在这项研究中，具有良好的球形和良好的单分散性的粘性中空介孔二氧化硅杂化物被用作氰基氰基丙烯腈（CNAP）的纳米载体，以制备粘性纳米农药（CNAP-HMS-PDAAM）。在田间条件下测试了CNAP-HMS-PDAAM的防治效果。结果表明，四种剂量的CNAP-HMS-PDAAM功效（30.0-69.0克活性成分/公顷）对稻纵卷叶螟（Guénee）喷洒后第3、7和14天与贝内维亚（34.5 g ai / ha）的差别不大。喷洒后第28天，所有四剂CNAP-HMS-PDAAM的疗效均显着优于贝尼维亚。此外，CNAP-HMS-PDAAM的剂量为34.5，39.0和69.0克功效成分/公顷对二化螟（沃克）均高于Benevia的显著更高（34.5克活性成分/公顷）。因此，CNAP-HMS-PDAAM表现出对稻纵卷叶（（Guénee）和suppress旋梭状。（W.kerker）的长期控制效果，这主要是由于其对稻叶的强粘附性和持续释放特性。另外，纳米载体具有良好的生物相容性，对水稻的生长没有明显的影响。
