Therefore, measurements are needed to keep ticks away from the body of any ruminant belonging to the agricultural life stock. The present study dealt with investigations to measure the efficacy of the insecticide deltamethrin (Butox® 7.5 pour on) against specimens of two important species (Ixodes ricinus and Rhipicephalus sanguineus). Four sheep and four young cattle were treated lege arte along the vertebral column with 10ml Butox® (deltamethrin) per sheep or 30ml Butox® per cattle. Day 7, 14, 21, and 28 after the treatment, hair was shaved off from the head, ears, the back, belly, and the feet being collected in separate, suitable plastic bags, and transported to the institute, where these hair were brought into close contact with either adult and/or nymph stages of I. ricinus and R. sanguineus. As results, strong, acaricidal effects were seen, which varied according to the parasite species, the origin of the hair (e.g., head, leg, etc.) and according to the period after the treatment. In sheep, the acaricidal effect was noted for the whole period of 28days along the whole body with respect to adults and nymphs of I. ricinus, while the acaricidal effects of deltamethrin were reduced for R. sanguineus stages beginning at day 21 after treatment. In cattle, the full acaricidal effect was seen for 21days in I. ricinus stages and for 14days in R. sanguineus, while the acaricidal efficacy became reduced after these periods of full action—beginning at the hair taken from the legs. Only R. sanguineus adults did not show any reaction on day 28 after treatment. Besides these acaricidal effects, repellent effects were also noted. Full repellency for both species was seen during the first 14days in sheep and cattle against Ixodes and Rhipicephalus, while the repellency was later reduced, especially in contact with hair from the legs. As conclusion, deltamethrin, besides its very good effects against biting insects, brings acaricidal as well as repellent effects against ticks, thus protecting the sheep and cattle from transmission of agents of diseases.
