Effects of Pirimiphos-Methyl on Non-Target Invertebrates.

The effects of pirimiphos-methyl have previously been assessed on blood-sucking insect species, pollinating insects, and target crop pest species. The sensitivity of non-target zoophagous and saprophage species to this insecticide remains largely unstudied. In laboratory conditions, we assessed the susceptibility of 43 species of invertebrates to pirimiphos-methyl.

Effects of Organic Xenobiotics on Larvae and Their Parasite .

Environmental contamination with xenobiotics affects organisms and the symbiotic relations between them. A convenient object to study relationships between parasites and their hosts is the host-parasite system " Linnaeus, 1758 (Coleoptera, Tenebrionidae) (Hammerschmidt, 1838) Stein, 1848 (Eugregarinorida, Gregarinidae)". For this experiment, we took 390 larvae and 24 organic compounds.

Repellent and Attractant Activities of Organic Compounds on Female and Male (Coleoptera, Staphylinidae).

The use of organic compounds in different spheres of human activity is accompanied by their influx to and accumulation in the environment. The negative impact of those compounds can be one of the reasons for a decline in populations and biodiversity of aboveground invertebrates. Chemical compounds can potentially cause a variety of effects (attractant or repellent) on insects, including species of the Staphylinidae family.

Immunophysiological State of Dogs According to the Immunoregulatory Index of Their Blood and Spleens.

In this study, the immunological characteristics of a dog's body were established, allowing for a quick reaction to any changes in the immune status and the development of an immunodeficiency state. The immunoregulatory blood index was determined to indicate the ratio of T-helpers and T-suppressors. The immunoregulatory index of the spleen was determined as the ratio of CD4+ cells to CD8+ cells in the field of view of a microscope (eyepiece 10, objective 40) after obtaining histological preparations according to generally accepted methods.

Survival of Nematode Larvae after Treatment with Eugenol, Isoeugenol, Thymol, and Carvacrol.

Background: Helminthiases inflict annual losses on the meat and dairy livestock industries. The commonest species of ruminant parasites are the nematodes: and , which lay eggs in the intestine and enter the feces. There, the eggs develop into larvae, which when voided with the feces crawl onto plants.

Influence of Inula helenium rhizomes and Matricaria chamomilla inflorescences on the biochemical and physiological parameters in male rats fed a high-fat diet.

Background: Pharmacological correction of a high-fat diet is of great interest to prevent the development of obesity and hypertension. More and more research is being done on the preventive use of medicinal herbs for excess caloric intake.

Objective: The aim of this study was to determine the general physiological effect of I.

Effect of Rhizome and Fruit Peel on the Metabolic Processes and Physiological Activity of Rats Fed with Excessively Fat Diet.

Research Background: (golden root) and (pomegranate), as well as a number of other species of medicinal plants, exert an array of biological effects: adaptogenic, antioxidant and anti-inflammatory. However, there are not enough contemporary studies of their influence on metabolic processes, especially in cases of imbalanced diet. Lipid dysregulation is the main reason for many diseases, including obesity, cardiovascular disorders, non-alcoholic fatty liver disease, hypertension, atherosclerosis and insulin resistance.

Promising medicinal plants for treatment of helminths of bison.

Bison bonasus (Linnaeus, 1758) and B. bison (Linnaeus, 1758) are mammals placed in the Red Book of the International Union for Conservation of Nature. Populations of those species of animals are under threat of extinction.

Modeling Sexual Differences of Body Size Variation in Ground Beetles in Geographical Gradients: A Case Study of (Illiger, 1798) (Coleoptera, Carabidae).

The aim of this study was to test the steepness of body size variation in males and females in the widespread ground beetle in geographical gradients. Beetles were sampled in 15 regions of Europe and Asia, and sampling territories differed 17° in latitude and 121° in longitude. We measured six linear traits in every captured beetle and formed a data set that included 2154 individuals.

Influence of essential oils on sporulation of Eimeria magna oocysts.

We researched the influence of essential oils from 14 species of plants (Piper cubeba, Cananga odorata, Pelargonium graveolens, Citrus sinensis, Eucalyptus globulus, Lavandula angustifolia, Picea abies, Citrus paradisi, Pterocarpus santalinus, Abies sibirica, Juniperus communis, Melaleuca alternifolia, Syzygium aromaticum and Cinnamomum verum) on the process of sporulation of Eimeria magna Perard, 1925. In the experiment we used 0.5% emulsion of oil during 72 hours, oocysts of E.

Nematicidal activity of aqueous tinctures of plants against larvae of the nematode Strongyloides papillosus.

This research was undertaken to evaluate the nematicidal activity of various concentrations of aqueous tinctures of 80 plant species towards L1-2 of S. papillosus. For the experiment with larvae of S.

The Impact of Acids Approved for Use in Foods on the Vitality of and (Nematoda) Larvae.

The laboratory experiment described in this article evaluated the death rate of larvae of (Rudolphi, 1803) nematodes of the Strongylida order and (Wedl, 1856) of the Rhabditida order under the impact of different concentrations of 8 flavouring acids and source materials approved for use in and on foods and in medicine (formic, wine, benzoic, salicylic, stearic, kojic, aminoacetic, succinic acids). Minimum LD for third stage larvae of (L) was observed with salicylic and wine acids, for L larvae with formic acid. Minimum impact on all studied stages of development of nematodes was caused by stearic, kojic, aminoacetic and succinic acids: larvae did not die in the course of one day even at 1 % concentration of these substances.

Trophic relations of Opatrumsabulosum (Coleoptera, Tenebrionidae) with leaves of cultivated and uncultivated species of herbaceous plants under laboratory conditions.

We carried out a quantitative assessment of the consumption of herbaceous plants by Opatrumsabulosum (Linnaeus, 1761) - a highly significant agricultural pest species. We researched the feeding preferences of this pest species with respect to 33 uncultivated and 22 cultivated plant species. This species of darkling beetle feeds on many uncultivated plant species, including those with hairy leaves and bitter milky sap, such as Scabiosaucrainca (5.
