METHOD FOR PROTECTING DOGS FROM FLEA INFESTATIONS

Abstract

The insecticidal efficacy of the active substances of abamectin 0.1% and fipronil 0.05% for flea dermatitis in dogs was evaluated. For research, 50 invasive animals were selected, which were divided into 5 groups in equal numbers. The animals were treated twice with an interval of 5 days by the method of large-drop spraying of the withers, dewlap, shoulder, thigh and abdomen. The insecticidal efficacy of the concentration of emulsions was evaluated daily by microscopy studies of the number of dead imago in animals. As a result of the experiments, it was found that when protecting dogs from flea infestations, the extensivity (EE) of the composition in doses of 0.005 ml/kg was 10% after 72 hours; in doses of 0.01, 0.03 and 0.05 ml/kg – 30%, 50%, 80%, respectively, after 48 hours; in doses of 0.01 ml/kg – 70%, 0.03 and 0.05 ml/kg – 100% after 72 hours, respectively. An analysis of the studies showed that a single application of a composite insecticide containing active ingredients (abamectin 0.1% and fipronil 0.05%) to the skin and hairline at the rate of 0.03 ml/kg per animal after 72 hours has a 100% efficacy in flea infestations in dogs.
