| Abstract: | On the surface of cows’ bodies were detected horseflies Chrysops caecutiens, Chr. pictus, Tabanus bovinus, T. sudeticus; blood-sucking flies Hydrotaea irritans, Haematobia spp., Haematobosca stimulans, Stomoxys calcitrans; and flies with licking mouthparts—Musca autumnalis, Morrelia spp., Fannia canicularis, Musca domestica, Muscina stabulans. The amount of flies on animals in July and August varied: maximum in the first and second decade of July (average of 27–56), quite large amount in late July and early August (14–39), and minimum from mid-August until the first decade of September (3–8). The studies were conducted on 1167 cows and showed high efficacy of Flyblock against zoofilnymi flies, horseflies, and midges. A consecutive period of protective action was established: after 12–14 days, the protective effect coefficient was 97%; after 17–20 days, it was 86%; after 23–27 days, it was 78%; and after 30 days, it was 75%. |
