Tick causes the serious economic losses in livestock production in worldwide. A study was conducted to determine the abundance of tick population on different body parts of cattle as well as in different geographical regions in 2017/018. Three study sites were taken from mid hill, inner terai and terai region of Nepal. Randomly total 45 dairy cattle (15 from each region) were included for the study. Regarding to the ticks distribution in cattle body part, higher number of ticks were recorded on dewlap (38.61%) followed by perineum and udder (25.10%), ear base (15.06%), tail base (9.07%), abdomen (7.34%) and withers (4.83%). Similarly, highest numbers of ticks were recorded in Chitwan (19.46 average number of ticks) cattle followed by Dang (9.13 average number of ticks) and least in Lamjung (5.73 average number of ticks) cattle. This result indicates that higher tick infestation was found in warm, moist, hidden sites with good vascular supply and thin skin in cattle body. Similarly, more number of tick population recorded in cattle keeping with poor animal husbandry practices
