Conduction of clinical trials and assessment of theinsecticidal and repellent properties of the “FLYBLOCK®insecticidal tag”, manufactured by AVZ Animal HealthLLC, Russia, during periods of maximum seasonal and daily activity of bloodsucking two-winged insects.

Based on the study results,the Repellent Coefficient (RC) of the product in livestock premises, in the housing of animals amounted to87.4– 96.7% (depending on the animals living conditions). When using the product on ground runs, as well freegrazing of cows RC was 91.2- 98.8%. On the basis of the results of calculation of bloodsucking two-wingedinsects and zoophilic flies in experimental and control groups, the high efficiency of the veterinary product“FLYBLOCK® insecticidal tag” was established when using for animals contamination within 17 weeks, withreduction of abundance index to 0 since the 2nd day of study, while in the control group the number of insectswas 46-68 insects per animal.
