Determination of optimal insecticidal properties of in vitro cyflutrin water solutions
Introduction. Modern realities in the development of livestock industries in Ukraine are quite complex and contradictory. A sharp decrease in the number of cattle in farms of different forms of ownership requires the owners of extreme attention to the veterinary provision of farms and the sanitary state of production facilities. In recent years, due to climate change, the range of distribution of arthropods of various classes has expanded. Necessary terms for animal protection have increased, and in many parasite populations resistance to previously used drugs has been formed. It is worth noting the rather wide market filling of means from domestic manufacturers. However, for the control of ectoparasites of productive animals, the spectrum of drugs is insignificant.
The goal of the work. Determination of insecticidal properties of water solutions of cyfluthrin of different concentrations on insects of Bovisola bovis.
Materials and methods. To establish the insecticidal properties of ectoparasites of cattle, water emulsions of cyfluthrin were taken in various concentrations. They were prepared on the basis of the serial drug "Cyflur". To determine the insecticidal action of the cyfluthrin, the imago of the bovine species Bovicola bovis served as the object of the study. Individuals for the experiment were taken by removing them from bovine animals, which was kept in the conditions of household farms.
Establishment of insecticidal activity of cyfluthrin was carried out by the method of planting experimental insects into pre-soaked working solutions of filter papers.
Results of research and discussion. Even in the absence of the manufacturer's recommendation for the use of a drag for the treatment of lactating cattle with ectoparasites, in vitro studies, diglutrin exhibited a high degree of insecticidal activity on the imago Bovisola bovis. The deaths of the imago of Bovicola bovis, which were used in control, were not marked.
Conclusions and prospects for further research. The presence of pronounced insecticidal activity of various concentrations of cyfluthrin is established. 100 % death occurred in 12-48 hours after the contact of the experimental imago Boviсola bovis, with the drug in various dilutions. Even after breeding a serial drug, after exposure to the active ingredient and lacquer, in vitro, insecticidal efficacy was manifested, but later. The prospects for further research are to determine the clinical efficacy of cyfluthrin with respect to pathogens of bovicolosis.
