ABSTRACT = {This work was carried out to evaluate the insecticidal effect of mono, bi and trimetallic nanoparticles (NPs) from
leaf extract of habanero pepper (<i>Capsicum chinense</i> Jacq.) on the red flour beetle (<i>Tribolium castaneum</i> herbst.)
and cotton mealybug (<i>Phenacoccus solenopsis</i> Tinsley). The results showed that Cu NPs, Cu/Mn NPs and Zn/Cu
NPs had high insecticidal effect against <i>T. castaneum</i> (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<sup>−1</sup>
. 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.},
