Objective:To green synthesize and characterize copper nanoparticles(Cu NPs)using Astragalus sinicus,as well as evaluate the acaricidal,larvacidal,and repellent activities of Cu NPs against Hyalomma anatolicum(***),one of the most prevalent ticks infesting cattle in saudi ***:Cu NPs were green synthesized by adding the Astragalus sinicus extract to a copper sulfate *** acaricidal,larvicidal,and repellent activities of Cu NPs against *** were assessed via the adult immersion test,the larval packet test,and the vertical movement behavior of tick larvae,*** effects of Cu NPs on acetylcholinesterase as well as oxidative enzyme activities were ***:The green synthesized Cu NPs displayed a spherical form with a size range of 15-75 *** exposure of adult *** to different concentrations of Cu NPs,the viability rate of adult *** and the mean number,weight,and hatchability of eggs were noticeably reduced,in comparison to the control group(Psiderably declined(Ps of 11.30 and 20.34μg/m L,*** maximum repellent activity of Cu NPs was observed at 50,100,and 200μg/m L with complete repellent activity after 60,120,and 180 min of exposure,*** NPs,mainly at 1/2 LC_(50)and LC_(50)concentrations,markedly suppressed the acetylcholinesterase activity of the larval stage of ***(Ps,mainly at LC_(50)dose,significantly elevated malondialdehyde level while declining glutathione-s-transferase level in *** larvae(Psions:Cu NPs show potent acaricidal,larvicidal,and repellent activities against adults and larvae of ***,further studies must be performed to clarify the precise mechanisms and the efficacy of Cu NPs in practical use.
