Ectoparasitoses of domestic and productive animals and ways to defend

The materials of the presented research cover the issues of entomoses prevalence in domestic and productive animals, determining the effectiveness of synthetic pyrethroids insecticides to ectoparasites of the following species: swine lice, canine and feline flea; malophages (chewing lice of chickens, cattle, horses), chicken bedbugs, sheep bloodsuckers. Studies have shown that the most common entomoses among productive and domestic animals are flea infestation, lice and malophagosis, and the prevalence of linognatosis and trichodectosis agents is relatively low. To determine the therapeutic efficacy of synthetic pyrethroids – "Extrazol-M" and "Neostomazan", animals with symptoms of ectoparasitic diseases were used. It was found that insecticides "Extrazol-M" and "Neostomazan" are effective against ectoparasites. The therapeutic effi cacy of "Extrazol-M" is 100% after one treatment – for flea infestation and two – for sifunculatosis and malophagoses. High effi ciency of animals’ with entomoses treatment with insecticide "Extrazol-M" is achieved by a combination of 3 synthetic pyrethroids. The drug has an advantage due to its cheapness and long-term storage. "Neostomazan" has suffi cient therapeutic effi cacy also, but has a short repellent period after treatment of animals. Thus, their owners must carefully follow the recommendations for the working solution concentration and drying of animal fur to minimize the risk of entering the animal. The active substances of the tested drugs of the pyrethroid series provide a repellent effect, scaring away parasites and preventing their bite. because in some animals prone to allergic reactions, even a single bite of ectoparasites is enough to start the process of allergic dermatitis. Synthetic pyrethroid drugs are more effective in the treatment of dermatological patients diagnosed with flea allergodermatitis or allergic reactions due to parasitism of sucking and chewing lice and, in contrast to systemic insecticides, act on ectoparasites by contact.

Key words: insecticides, "Extrazol-M", "Neostomazan", synthetic pyrethroids, ectoparasites, fleas, lice, malophages, bedbugs.
