INTEGRATED METHODS OF TERMITE CONTROL

Posted in 2021, BIOLOGY, Issue №6 (108) June 2021, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The current study uses the literature and experimental data to determine the rational methods of termite control. Among the abundance of anti-termite measures, there is no universal means of eliminating all types of termites, the vital activity of which depends on a variety of anthropogenic and biotic factors. In this regard, the search for effective ways to eliminate termites adapted to local conditions is an urgent task.

The article presents the results of attempts to eliminate Turkistan termite species. The study determines that the integration of control methods leads to an increase in the quality of protection against this pest.

When using an insecticide to control termites, their lifestyle is also taken into account. For an effective application of measures against the termites, the main task is to destroy the female, which is engaged only in reproduction. The female is usually located almost always underground and feeds on food delivered by worker termites.

The article presents new insecticidal compositions and methods of termite control as well as preventive measures during construction and repair work indoors. The developed insecticide contains borax, boric acid, sulfur-perlite-containing waste including millet, honey, and sugar as food bait. A mixture consisting of borax, boric acid, and sulfur-perlite-containing waste has a high nerve-paralytic effect. Termites gradually experience paralysis and die. Honey, sugar, and millet serve as food baits. In addition, millet, while getting into the body of termites, swells and closes the food passages, which additionally leads to their death.

It is recommended to use the insecticidal part of the proposed product (borax, boric acid, and sulfur-perlite-containing waste) for preventive measures by adding it to paint, construction adhesives, cement, and other mixtures.

RESULTS OF A STUDY OF THE BIODIVERSITY OF THE PROTECTED AREA OF REGIONAL SIGNIFICANCE “AKATOVSKY QUARRY” (KALUGA OBLAST)

Posted in 2021, BIOLOGY, Issue №6 (108) June 2021, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The aim of the study was to examine the flora and fauna of the Akatovsky quarry, which is currently one of the specially protected natural areas of regional significance located in Kaluga Oblast. In the current state, the Akatovsky quarry is a rather vulnerable object in terms of preserving the biodiversity of the territory and the resource-reproducing functions of the landscape. For the vast majority of biota species, the quarry is an enclave territory, which, on the one hand, prevents the exchange processes between populations, and on the other hand, there is a threat of the introduction of adventitious species. The research found that 5 species of herbaceous plants listed in the Red Data Book of Kaluga Oblast are found in the area under study: 3 representatives of the Orchidaceae (Epipactis atrorubens (Hoffm.et Bernh.) Schult; Epipactis palustris (L.) Crantz; Corallorhiza trifida Chatel.), and Polygala amarelle Crantz.) and Calamagrostis Langsdorfii Trin. This confirms the high conservation status of the territory. Taking into account the results of the study carried out by the authors, the territory was assigned the status of specially protected on 23.03.2020.

A COMPARISON OF THE BACTERICIDAL ACTIVITY OF OFLOXACIN SEPARATELY AND IN COMBINATION WITH BENZYL ALCOHOL AGAINST PATHOGENIC MICROORGANISMS AND FUNGI THAT CAUSE OTITIS MEDIA

Posted in 2021, BIOLOGY, Issue №6 (108) June 2021, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The problem with otitis media is always relevant for otolaryngologists. It is a known fact that the inflammatory process can form in the cavities of the middle ear. The biggest problem is the prevalence in early childhood. Acute otitis media is cured if the appropriate treatment is applied in time. If the appropriate dentin is not used, there is a risk of permanent hearing loss. Bacteria are the most important microorganisms that cause otitis media, especially Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhali. Therefore, for the bactericidal action on pathogenic microorganisms, antibiotics that are effective and safe were chosen, among them were fluoroquinolones and local antiseptics such as benzyl alcohol, which demonstrated thoroughly satisfying results, since experiments showed that when mixing ofloxacin with benzyl alcohol in an alcohol medium of 70%, the bactericidal ability of microorganisms that cause otitis media of the middle ear will increase. A six-fold repetition of the experiment was performed on most types of microorganisms that can cause otitis media, such as Escherichia coli, Staphylococcus aureus, Proteus vulgaris, Basillus subtilis, Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis. The study also calculated the diameter of bacterial growth retardation with antimicrobial agents on the agar layer. An additional bacteriostatic reaction was obtained in a mixture of ofloxacin and benzyl alcohol.
