The effectiveness from the drug of Flyblock insecticidal tag at arachnosis and entomoses in cattle.
Agro-climatic conditions of the Stavropol Territory are favorable for habitats of gulf coast ticks, carriers of infectious and invasive diseases in animals and humans, which cause significant damage to the development of productive livestock rearing. In the Stavropol Territory there are 16 species of gulf coast ticks belonging to 6 genera. Transmissible invasions are accompanied by a decrease in a body weight, a loss of productivity, the quality of the integument is deteriorating, an anemic syndrome develops, the reproductive capacity of animals is disturbed, and often their death occurs. All of the above speaks about the importance in the control of the gulf coast ticks. The use of only traditional means and methods of protecting productive animals from the attack of gulf coast ticks is ineffective. In this connection, the company LLC "AVZ S-P" (Russia, Moscow region, Sergiev Posad) has created ear tags with the content of synthetic pyrethroids, this is a Flyblock insecticidal tag. In order to prevent and control arachnosis and entomoses in farm animals and to study the effectiveness from the acaricidal and insecticidal action of the Flyblock® insecticidal tag drug of two series on horned cattle and small horned animals, we conducted studies of this drug in various regions of the Stavropol Territory (PPF breeding farm named after Lenin, Kievka village, Apanasenkovsky district; APC "Gigant" Kolkhoz, Blagodarnensky district; Experimental station of VNIIOK - branch of the FGBNU "North Caucasian FNATS", Tsymlyansky village, Shpakovsky district; private flock, Neftekumsky district; APC "Breeding farm "Vtoraya pyatiletka", Bol'shaya Dzhalga village, Ipatovsky district). A study of the effectiveness from the Flyblock® insecticidal tag drug of two series showed: 1. The acaricidal effect of Flyblock® tags with series 070617 on horned cattle against gulf coast ticks has made 7 days; the repellent was 14-19 days. 2. The anti-parasitic effect of the Flyblock® tags with series 070617 against thelaziosis in horned cattle was 1.5 months. 3. The absolute and average daily gains of live weight in heifers of the Kazakh white-headed breed after applying the Flyblock® tags of series 070617 was higher by 14.9-17.5% compared to the control. At the same time, feed conversion per 1 kg of live weight gain is reduced by 0.1 fodder units. 4. The acaricidal effect of the Flyblock® with series 020317 on ewe lambs against gulf coast ticks has made 7 days, the repellent was 19 days.
