Comparative Studies on The Effect of Some Citrus Oils and Their Silver Nitrate Nanoparticles Formulation on Camels Tick, Hyalomma dromedarii (Acari: Ixodidae)

ticks are ectoparasite infesting camels. The acaricides used in controlling tick fauna developed resistance problems. Therefore, some citrus oils as well as their nano preparations were proposed as alternative agents during the present study.Fresh fruits peels were picked to extract oils by the Hydro-distillation method. Oil extracts were characterized by GC/MS technology. The phytochemical constitute present in Citrus sininses var balady were β-Pinene 2.8%, Limonene 97% while in Citrus limon were β-pinene 37.11%, α-Pinene 6.617% and Limonene 55.6%. Silver nitrate nanoparticles of citrus oils prepared were characterized by Electron microscope; TEM, SEM and EDX. The result showed Nano preparations were spherically
