摘要

研究了辣椒叶提取物单、双、三金属纳米粒子(NPs)对红甲虫(Tribolium castaneum herbst.)和棉粉蚧(Phenacoccus solenopsis Tinsley .)的杀虫效果。结果表明,铜NPs、铜/锰NPs和锌/铜NPs高杀虫效果与t . castaneum 96 h后死亡率(63% - 80%)。铜NPs和锌/铜NPs显示也对p . solenopsis杀虫作用,但程度不一样96 h后(20% - 28%)。关于物理化学特征,铜NPs电动电势21.1 mV,而铜/锰NPs和锌/铜NPs展出200 mV的ζ电位。Cu NPs、Cu/Mn NPs和Zn/ Cu NPs的多分散指数(PDI)分别为10.1、29.16和14.34。NPs的TF-IR光谱在600 ~ 4000 cm−1之间变化。EDX质量百分比分别表明Cu/Mn NPs和Zn/Cu NPs中存在Cu(0.29% ~ 2.4%)、Mn(1.4%)和Zn(2.6%)。

Insecticidal Activity and Physicochemical Characterization of Nanoparticles from Foliar Extract of Capsicum chinense

This work was carried out to evaluate the insecticidal effect of mono, bi and trimetallic nanoparticles (NPs) from leaf extract of habanero pepper ( Capsicum chinense Jacq.) on the red ﬂ our beetle ( Tribolium castaneum herbst.) and cotton mealybug ( Phenacoccus solenopsis Tinsley). The results showed that Cu NPs, Cu/Mn NPs and Zn/Cu NPs had high insecticidal effect against T. castaneum (63% – 80% mortality after 96 h). The Cu NPs and Zn/Cu NPs showed also insecticidal effect against P. solenopsis , but to a lesser extent (20% – 28% after 96 h). With regards to the physicochemical characterization, Cu NPs had a zeta potential of 21.1 mV, whereas Cu/Mn NPs and Zn/Cu NPs exhibited zeta potentials of 200 mV. The polydispersity index (PDI) values for Cu NPs, Cu/Mn NPs, and Zn/ Cu NPs were 10.1, 29.16, and 14.34, respectively. The TF-IR spectra of the NPs varied from 600 to 4000 cm − 1 . The EDX weight percentages showed the presence of Cu (0.29% – 2.4%), Mn (1.4%), and Zn (2.6%) in Cu/Mn NPs and Zn/Cu NPs, respectively.

期刊介绍： This journal publishes high quality peer reviewed original research and review articles on macromolecules and additives obtained from renewable/biobased resources. Utilizing a multidisciplinary approach, JRM introduces cutting-edge research on biobased monomers, polymers, additives (both organic and inorganic), their blends and composites. JRM showcases both fundamental aspects and applications of renewable materials. The fundamental topics include the synthesis and polymerization of biobased monomers and macromonomers, the chemical modification of natural polymers, as well as the characterization, structure-property relationships, processing, recycling, bio and environmental degradation and life cycle analysis of the ensuing materials, in view of their potential applications. Within this sustainability approach, green chemistry processes and studies falling within biorefinery contexts are strongly favored.
