Abstract

Phytonanoparticles can be used as an alternative method for pest control in agriculture. The objective of this study was to evaluate the insecticidal activity of mono, bi and trimetallic phytonanoparticles (PNPs) synthesized from cachanilla (Pluchea sericea Nutt. Coville) and epazote (Chenopodium ambrosioides L.) against the red flour beetle (Tribolium castaneum) and the cotton mealybug (Phenacoccus solenopsis). Overall, T. castaneum showed greater sensitivity to PNPs than P. solenopsis. The trimetallic PNPs, Zn/Cu/Mn of P. sericea showed significantly higher effect against T. castaneum than the crude aqueous extract of P. sericea. No other PNPs showed more effect than their respective aqueous plant extract. Physicochemical characterization of the most active PNPs showed that the Zn/Cu/Mn NP of P. sericea had a strong zeta potential of +200 mV, hydrodynamic size of 16 nm, and contains zinc (6.73%), copper (0.13%), and manganese (4.69%). This study suggests that the trimetallic Zn/Cu/Mn PNPs of P. sericea have high insecticidal effect on T. castaneum, but low toxicity on P. solenopsis. Additional research on the mode of action of PNPs on insect targets is required.

对 Tribolium castaneum 和 Phenacoccus solenopsis 的杀虫活性以及活性植物蛋白颗粒的特征描述

植物激素颗粒可用作农业害虫控制的替代方法。本研究的目的是评估由桔梗（Pluchea sericea Nutt. Coville）和附子（Chenopodium ambrosioides L.）合成的单、双和三金属植物激素颗粒（PNPs）对红面粉甲虫（Tribolium castaneum）和棉蚧（Phenacoccus solenopsis）的杀虫活性。总体而言，T. castaneum 对 PNPs 的敏感性高于 P. solenopsis。蛇麻属植物的 Zn/Cu/Mn 三金属 PNPs 对 T. castaneum 的作用明显高于蛇麻属植物的粗水提取物。没有其他 PNPs 显示出比各自的植物水提取物更强的效果。最有活性的 PNPs 的理化特征显示，蛇莓的 Zn/Cu/Mn NP 具有+200 mV 的强 zeta 电位，水动力尺寸为 16 nm，含锌（6.73%）、铜（0.13%）和锰（4.69%）。这项研究表明，P. sericea 的 Zn/Cu/Mn 三金属 PNPs 对 T. castaneum 有较高的杀虫效果，但对 P. solenopsis 的毒性较低。关于 PNPs 对昆虫靶标的作用模式还需要进一步研究。
