The efficacy of a commercial insecticidal preparation based on Paecilomyces fumosorosea, Pecilomycin PM116, against root-knot nematode (Meloidogyne arenaria) was evaluated on tomatoes. A comparison was made with biological (Nematophagin) and chemical (Vydate 5G) nematicides. Pecilomycin and Nematophagin did not suppress the development of plants, their weight and size were at the level of healthy controls. The analysis of photosynthetic pigments showed that the chlorophyll b level, the sum of chlorophylls and carotenoids when the root system was treated with Pecilomycin was comparable to healthy controls. Despite the fact that the plants treated with Pecilomycin were completely infected, their infection rate was 1.27 times lower than the controls, and single galls were only present on the roots. The treatment of the roots with Pecilomycin did not significantly affect the number and size of galls; the females in them were at the control level; however, the number of eggs in oothecae was 1.5 times less. Thus, Pecilomycin has an inhibitory effect on the root-knot nematode and a beneficial effect on the tomato plant. Further research and search for new strains of P. fumosorosea with high virulence against one or more pests opens up opportunities for the creation of new bionematicides.

The purpose of this work is to study the spread and species composition of pathogens of trematode infections among cattle in North-Western and Southern Uzbekistan. The studies were carried out on the territory of the Republic of Karakalpakstan, Khorezm and Kashkadarya Regions in 2020–2023. Helminthological material was collected in all seasons of the year. In total, 364 heads of cattle were examined by complete and partial helminthological dissections. As a result of the studies carried out in the northwestern and southern regions of Uzbekistan, 9 trematode species belonging to 7 genera, 5 families and 4 orders of the class Trematoda were recorded. In the northwestern region, 175 heads of cattle (65.3%) out of 268 examined animals were infected with certain trematode species. Of those infected, 124 had associative invasions, and 51 had monoinvasions. In the southern regions, 41 animals (43.2%) out of 96 examined animals were infected with trematodes. Of the infected animals, 27 (65.8%) were infected with mixed trematode infections, and 14 (34.1%), with monoinvasions. Of 9 trematode species under consideration with natural and synanthropic focality, Schistosoma, Fasciola, and Dicrocelium were recorded.

Toxoplasmosis occupies one of the first places in the world among all foodborne parasitic diseases, since it is recorded on all continents and can affect many species of mammals and birds. The causative agent of toxoplasmosis, Toxoplasma gondii, is the obligate zoonotic parasite that can be transmitted from animals to humans. The main sources of infection are soil contaminated with cat feces, poorly thermally processed meat, and transplacental route of transmission. There is scanty data available in Armenia to assess the role of livestock animals as a source of alimentary toxoplasmosis in humans. In this regard, the purpose of this work was to conduct a pilot study on the identification of seroprevalence in some livestock animals using the Tavush Region of Armenia as an example. An ELISA was used to screen 241 samples for the detection of total T. gondii antibodies in blood serum. As a result, 42 (17.4%) of all tested samples reacted positively including 23 (39%) samples from small cattle, 4 (28.6%) from pigs, and 15 (8.9%) from cattle. Thus, our data correlate with the data of a number of foreign authors with the prevailing proportion of seropositive sheep and pigs. To obtain a complete picture of toxoplasmosis among livestock animals, research in this direction should be continued.

Within the section of general helminthology, based on the diversity analysis of biological cycles of helminth development, and the objective availability of common algorithms in closely related species, a conceptual proposal has been developed to introduce a new stylized category, the Helminth Developmental Biology Formula (DBF), into theory and scientific practice. The new category, the DBF, is designed for a logically sound, stylized and concise presentation of essential elements of bioecological characteristics of helminths. Basic regulations for the formation of the formula structure have been developed. A number of indicative parameters are proposed which, in accordance with helminthological terminology and pictograms, form the informational basis of the helminth DBF category. The regulation algorithm is universal, and, taking into account the bioecology characteristics of helminths, it is applicable to the DBF formation for representatives from various zoological taxa. On the example of biological cycles of development of trematode Paramphistomum daubneyi Dinnik, 1962, cestode Spirometra erinacei-europaei (Rudolphi, 1819), nematode Avioserpens mosgovoyi Suprjaga, 1965, Acanthocephala Macracanthorhynchus hirudinaceus (Pallas, 1781), and Monogenea Diplozoon paradoxum Nordman, 1832, in a stylized format, the structure and information content of the category Helminth Developmental Biology Formula are presented. The field of practical use of the helminth DBF is the following: 1) scientific and methodological, educational and reference helminthological literature, as an additional subheading within the main Helminth Developmental Biology Section; 2) in computer databases of various thematic orientation, in scientific characterization of the main bioecological parameters of helminths, due to the need to present material in a concise format.

Among the most common and dangerous parasitic diseases of animals and humans is fascioliasis. The most effective against Fasciola is triclabendazole ("Fasinex 5.0%" suspension), imported by Siba-Geigi, which is practically not used in Russia due to its high cost. Considering the huge economic damage caused by fascioliasis, we have developed a new complex preparation using innovative mechanochemical technology based on the substance of triclabendazole "Triclafascid", which is 5 times more active than the substance of triclabendazole against fascioliasis. The drug is an intermolecular complex in the form of an easily flowing solid dispersed powder with a size of 0.1–10 microns. The drug is administered orally once to cattle and sheep for therapeutic and prophylactic purposes for acute and chronic fascioliasis, to sheep at a therapeutic dose of 2.0 mg/kg and to cattle 2.5 mg/kg for the AI, respectively, and 20 and 25 mg /kg for the drug, once individually in the form of an aqueous solution. In case of mass deworming of animals, it is convenient to give the anthelmintic by a group method to 10–20 animals, mixed with mixed feed at a dose of 3.0 mg/kg for the AI (for the preparation 30 mg/kg).

Our research is devoted to the study at the present stage of the species composition and distribution of blood-sucking dipteran insects, carriers of dangerous parasitic zoonoses in the Meghri District of the Syunik Region, the Republic of Armenia. The studies were carried out from June 25 to December 3, 2022 in the Meghri District of the Syunik Region (altitude 394–565 m above sea level, semi-desert zone) along the Armenian-Iranian border, since it is here that invasive species are most likely to enter Armenia. For the first time in Armenia, automatic light Mothmatic Freezer Traps, and high-tech automated traps for collecting nocturnal entomofauna combined with a freezer were used as equipment for collecting nocturnal insects with positive results. Based on our research, it was established that the fauna of nocturnal bloodsucking Diptera in the Meghri District was quite diverse and was represented by 9 midge species: Culex pipiens, Cx. quinquefasciatus, Culiseta annulata, Aedes caspius, Ae. vexans, Ae. geniculatus, Anopheles maculipennis, An. claviger, An. hyrcanus and 3 mosquito species: Phlebotomus papatasi, Ph. kandelakii and Ph. sergenti.

The most well-known ectoparasites of dogs and cats are fleas and Acariformes, which are also carriers of infectious and invasive diseases. Animals admitted to the veterinary clinic served as the material for the research. The study involved 3346 animals, of which 1596 cats and 1707 dogs. Classical life-time diagnostic methods of ectoparasitosis were used. The results obtained show that among all dermatological patients, the proportion of those infected with ectoparasites was 47.6%. Among ectoparasites, fleas were most often recorded; the prevalence of infection was 4.78%. Aphanipterosis was recorded in all seasons of the year, the maximum invasion of 1.76% was observed in autumn, and the minimum of 1.30% in winter. The second most common disease was otodectosis (IP 1.94%). The heyletiellosis rate was 0.27% (total 9 animals, including 1 cat); and demodicosis, 0.24%. Notoedrosis was only diagnosed in the cats with IP 0.15%, sarcoptosis was recorded in the dogs with IP 0.09%. Ectoparasite infections are recorded at any time of the year, however, the peak of invasion occurs to a greater extent in the summer-autumn months. They can also occur at any age, but are more common in cats and dogs under one year of age.

One of the promising high-tech systems for the use of agricultural chemistry can be the development of original forms of agrochemical preparations (fertilizers and pesticides) of prolonged action. The slow-release polymeric composites formed by our technology have a number of advantages. A single injection of preparations during seeding allows avoiding multiple medical top dressings (for fertilizers) and treatments (for pesticides) during the growing season. The most important principle of the effectiveness of using agricultural chemistry is the linking of the timing of top dressings and treatments to the developmental phenophases of both plants and parasites. Much depends on the characteristics of the development of parasites. For example, larvae of cyst-forming nematodes are vulnerable to drugs during migration in soil. However, the cyst-forming nematode of potato develops in one generation for a season, and the cyst-forming nematode of beet develops in 3–4 generations. In the latter case, additional use of modified forms of nematicides is possible. In favor of drugs with prolonged action (apart from a multiple increase in economic efficiency, especially in the event of a shortage of the drug), we should attribute the technological possibility we have worked out to program the action of drugs. We have adopted the following reference terms for prolongation, 1, 3 and 6 months. Technologically, this is achieved by the polymer concentration in the composite. In this case, our method can be used to take into account weather risks.

Pruritic dermatosis is chronic persistent processes. The principal symptom is tormenting itchy sensation excruciating for patients affected. Medical treatment is often ineffective. Itchy skin may be caused by parasite invasions. Whether external or endogenic, they are highly toxic, which is important in pathogenesis. Therefore, it is necessary to exclude parasitosis in patients with itchy skin. Intoxications and allergic reactions caused by polypragmasy are also capable to cause itching. In total, 64 patients were examined. They underwent histocoprological analysis for helminthic infections. Of them, 41 patients were found to have mono- and polyinvasions and abnormal intestinal macro- and microbiome, which required specific therapy. In 13 patients, the cause was polypharmacotherapy. General cryogenic therapy was applied in 12 patients with generalized itching. Exposure of skin parasites to extreme law temperatures discontinues their life cycle. The effects of general cryogenic treatment result in itching elimination, reduced inflammation, pain attenuation and wound healing. The skin is an informative organ showing therapeutic efficacy when properly treated. Application of general cryogenic treatment as an etiologically focused method is especially prescribed against external parasite infections (such as scabies, dirofilariasis, Morgellons disease).

Soil, bottom sediments, and sewage sludge are the main sources of infection of humans and animals with helminth eggs, and protozoan cysts and oocysts. For the disinfection of environmental objects, chemical disinfectants are successfully used. To identify the most effective disinfection means for soil and environmental objects, laboratory studies of the ovicidal activity of disinfectants are carried out on soil samples. Currently, laboratory practice has no standard methods available for determining the ovicidal efficacy of disinfectants in the soil. A device is offered for the experimental selection of disinfectants for disinfecting soil, geologic material, sewage sludge or bottom sediments contaminated with helminth eggs, and protozoan cysts and oocysts. The laboratory device is a three-segment steel column in the form of a cylinder with supports provided at the base, and a cover with a foam outlet and a filler neck located on the upper part, and a storage tank for collecting the spent disinfectant solution located in the lower part. The cylinder is filled with soil segment by segment, and microcontainers with bioagent are placed at the bottom of each segment. The soil is poured with a disinfectant; and the microcontainers are removed from the soil after various exposure periods to determine the ovicidal activity of the disinfectant.
