Abstract
The aim of the research. To compare the ovicidal efficiency of insectoacaricides of different composition and manufacturers on flea eggs (Ctenocephalides spp.) for treatemnt of the premises where animals live.
 Materials and methods of the research. The study was conducted on the basis of the clinic of veterinary medicine "Vetservice" Sumy, laboratory "Veterinary Pharmacy" and "Innovative technologies and safety and quality of livestock products" of Sumy National Agrarian University. The ovicidal effect of insectoacaricides on flea eggs of Ctenocephalides spp. was studied. Ctenocephalides spp. eggs were selected from the pet bedding on which the animal spended most of its time, namely the cats. The studied material was selected with a cosmetic brush. Ctenocephalides spp. eggs were placed into a Petri dish of 10 eggs per each dish. The test material was introduced with a dental probe. There were 4 test dishes, which were treated with insectoacaricides (each test dish was treated with a separate drug) and 1 control dish with no treatment. Microscopy was conducted under a light microscope with magnification X8 of each egg, with following treatment of each egg with insectoacaricides. Monitoring was conducted in 24, 48 and 72 hours after treatment.
 Results. Research has shown that drugs which demonstrated 100 % ovicidal effectiveness were Sentry Home (pyriproxyfen – 0.02 %, permethrin – 0.2 %, n-Octyl Bicyclohepten – 1.0 %) in 24 hours and Neostomazan (CEVA)(transmix – 5.0 g, tetramethrin – 0.5 g) in 72 hours.
 Conclusions. Insectoacaricide drug Sentry Home (pyriproxyfen – 0.02 %, permethrin – 0.2 %, n-Octyl Bicyclohepten – 1.0 %), used for the treatment of the premises where the animals live, showed the most pronounced ovicidal effect in 24 hours.
Highlights
The main object of the study was the ovicidal effect of the insectoacaricide drugs Sentry Home, Neostomazan 1:200, manufactured by CEVA, Neostomazan 1:200, manufactured by PRODUCT, Extrazol M on flea eggs (Stenocephalides spp.), namely the number of living eggs after treatment with insectoacaricides, to determine the effectiveness of the treatment of the premises when using insectoacaricides in practice.Fleas are temporary parasites
The results of ovicidal action of the insectoacaricide drug Sentry Home manufactured in the USA Before treatment: The complete deformation was not found in any egg
There was a slightly deformed lower pole in two eggs. This is due to the fact that such a condition of an egg occurs before hatching from the larva. This fact was proved during the study of the biology of Ctenocephalides spp. egg development and which was found in no literary source
Summary
The main object of the study was the ovicidal effect of the insectoacaricide drugs Sentry Home, Neostomazan 1:200, manufactured by CEVA, Neostomazan 1:200, manufactured by PRODUCT, Extrazol M on flea eggs (Stenocephalides spp.), namely the number of living eggs after treatment with insectoacaricides, to determine the effectiveness of the treatment of the premises when using insectoacaricides in practice. The development of insects occurs with a complete transformation. The life cycle of fleas is a complete transformation, lasting from 14 to 140 days, depending on temperature and humidity. They live in animal fur or nests. Females after fertilization lay up to 450–2500 eggs in the cracks of buildings, trees, land, debris and sometimes on animal skin, where they fall into places of sleep or rest of the animal
