Stored product pests cause a significant decrease in the quantity and quality of stored products each year. Trogoderma granarium (Coleoptera: Dermestidae) is a stored product pest that is very difficult to control and subject to quarantine. Recently, the emerging scientific field called "nanotechnology" suggests that nanoparticles can be used as a promising and reliable alternative pesticide to control such pests. In this study, copper nanoparticles (g - Cu NP) were synthesized from Origanum sp. extract by the green synthesis method to investigate its insecticidal efficiency against T. granarium. The presence of synthesized g-Cu NPs was confirmed by observing the color change and using analytical techniques. Surface Plasmon resonance measurement of g - Cu NPs was observed at 385 nm. According to the TEM analysis results, g - Cu NPs are 6.59 ± 0.57 nm in size. XRD and EDX analyzes showed the crystallinity of the synthesized NPs. FTIR analysis indicated the use of the extract as a reducing and capping agent. A 90% mortality rate was recorded in the investigations of the insecticidal activity of g - Cu NPs against T. granarium at 250 and 300- ppm concentrations. Expression analysis of the Reactive Oxygen Species (ROS) detoxifying, TgSOD, TgCAT, and TgGPX genes showed high expression of these genes in insects fed with g-Cu NPs. Based on the findings, the synthesized g-Cu NPs can be efficient insecticides and could become potential components of integrated pest management (IPM). However, further research on the effects of other types of NPs on this pest could also be recommended.
