The dissertation work is devoted to the study of comparative evaluation of complex measures for ectoparasitosis of small domestic animals. The results of research significantly improve measures to combat and prevent carnivorous ktenocephaly. It is established that ectoparasitosis of small domestic animals is often registered in the central and adjacent urban areas of Sumy. There is a tendency to increase the number of cases. So. from 2015 to 2020, 988 (25%) cases of small domestic animals were diagnosed with otodectosis, 268 (6.8%) cases – demodectic mange, 2662 (67.5%) cases - ktenocephaly, 26 (0.7%) cases – notohedrosis. Ctenocephaly is mainly registered in cats aged 1.5 months to 3 years – 561 (50.8%), from 4 to 10 years – 306 (27.7%), older than 10 years – 237 (21.5%). In dogs, ktenocephaly is registered at the age of 1.5 months to 3 years – 711 (45.6%), from 4 to 10 years – 647 cases (41.5%), older than 10 years – 200 (12.9%). Outbreak dogs and cats are more likely to suffer from ktenocephaly. High incidence of stray dogs and cats, associated with home-walking lifestyle and untimely insecticide treatment, both animals and the premises where they live. Ctenocephaly is more common in males – 857 cases, which is 55%, less often in female dogs – 701 cases, which is 45%, in cats – 585 (53%), less often in cats – 519 (47%). Studying the dynamics (average number for 5 years) of the incidence of small domestic animals for ktenocephaly, it was found that the disease has a pronounced seasonality, and is more often registered in the spring, summer and autumn. We attribute this to the favorable conditions (high temperature and humidity) for the development of Ctenocephalides felis and Ctenocephalides canis and the active lifestyle of small domestic animals during this period.
