Effectiveness of insectoacaricidal agent from the group of synthetic pyrethroids in cattle Psoroptosis
Psoroptosis or scabies on the skin is a widespread parasitic disease in cattle. It is diagnosed for signs such as skin inflammation, itching, hair loss, and wasting. Psoroptosis causes significant economic damage to Russian farms, especially those specializing in dairy farming. The paper presents the results of a study to determine the effectiveness of an insectoacaricidal agent from the group of synthetic pyrethroids in the form of an aqueous emulsion in the treatment of cattle suffering from psoroptosis. The studies were carried out in the private sector on the territory of the Karachay-Cherkess Republic in 2019. 135 heads of cattle of cross breeds, aged from 3 to 5 years, with an average body weight of 400-450 kg, were subjected to acarological examination. The object of study was mites-the causative agents of psoroptosis in cattle, namely eggs, larvae, nymphs and adults. As a result of the studies carried out, it was found that a 0.05 % concentration of an aqueous emulsion of an insectoacaricidal agent containing etofenprox as an active ingredient, with a double treatment of livestock by the method of small-drop spraying at the rate of 1 liter per animal, showed 100 % efficiency.
