The article presents data on the determination of the insecticidal effectiveness of cyfluthrin for the damage of cattle caused by ectoparasites. Insecticidal efficiency was determined on groups of cattle of different sex and age groups. The research was carried out during the period of maximum intensity of infestation by ectoparasites. Counting of insects on the body of animals was carried out before their treatment, as well as on the 2nd, 7th, 15th and 30th day. According to the obtained data, in cows treated with a preparation based on cyfluthrin, the extent of bovicolosis invasion decreased already on the 2nd day and amounted to 23.3%, in the group of heifers of parous age, on the 2nd day after treatment, the extent of invasion was 22.2%, in the group of young animals, they noted a decrease in the extent of bovicolosis infestation on the 2nd day after treatment - 77.8%. The extent of invasion due to siphunculatosis in the group of cows treated with the drug on the 2nd day was 20.0%, in the group of heifers of mating age - 22.2%, in the group of young calves - 88.9%. The rate of extensibility for the treatment of groups of cows, heifers of mating age, as well as young animals on the 30th day of the experiment was 90.0, 91.5, and 91.1%, respectively. In cows treated with cyfluthrin, the intensity of invasion due to bovicolosis decreased already on the 2nd day and amounted to 43±3.1 exps/100 m2 of the skin of the animal’s body, in the group of heifers of mating age, the intensity of invasion was 46±2.1 exps/100 m2, in the group of young animals – 32±3.3 copies/100 m2. Intensity efficiency for processing groups of cows, heifers of mating age, as well as young animals on the 30th day of the experiment was 87.5%, 84.3% and 90.7%, respectively. The conducted set of studies established that when determining the effectiveness of cyfluthrin against bovicolosis and syfunculatosis, the intensity of treatment of groups of cows infested with hair-eaters on the 30th day of the experiment was 87.5%, among heifers of mating age, as well as young animals - 84.3 and 90.7 % respectively. The intensity efficiency indicator for the treatment of groups of cows, heifers of mating age, as well as young animals infested with lice, on the 30th day of the experiment was 87.0, 91.8 and 84.5%, respectively. Therefore, in vivo experiments, cyfluthrin showed high levels of insecticidal efficiency against causative agents of ectoparasites of cattle (sifunculat and bovicol).

In response to suggestions that the incidence of louse infestations in New South Wales has increased markedly, a survey of 173 producers was conducted in the Tablelands Livestock Health and Pest Authority region using visual detection and a questionnaire to document retrospective lice history. An estimated apparent prevalence of 16.5% is a moderate increase from the 10% reported in 2004. On a subset of the surveyed sheep flocks sheep, lice-specific immunoassay conducted by the New South Wales Department of Primary Industries were used to detect low levels of infestation that were not identified by visual detection. This provided a true prevalence estimate of 30%. These results will be used to promote improved control and preventative strategies.
