Abstract

The developments described in this article relate to the control of diseases of honey bees (Apis mellifera сarnica). Varroatosis is an invasive contagious disease of bees caused by the activity of the Varroa destructor mite. This disease, if uncontrolled, can lead to the death of the bee colony. The complexity of the fight is due to the ubiquitous distribution of the pathogen and the good adaptive adaptations of the tick, developed over decades of fighting it.

The review presents physical, chemical, biological and zootechnical methods of tick control. The drugs are listed, indicating the active substances that are currently used to treat infected bee colonies.

Based on the literature review, a plant material was selected that proved to be an effective remedy for combating varroatosis. Anethum graveolens and Abies sibirica were selected for further work. Using a 40% water-alcohol mixture, a tincture was obtained with a ratio of extractant : raw material – 2 : 1 and a ratio of herbal components fragrant Anethum graveolens : Abies sibirica – 70 : 30. The resulting tincture was evaporated, the extract was sealed into ampoules. Alcohol must be removed, because this substance has an exciting effect on bees and harms the entire bee family.

Another form of the preparation was obtained on the basis of an aqueous tincture of plant materials (ratios of plant components and extractant : raw material, similar). The tincture, using freeze-drying, was dried to a powder.

In the course of the study, a pharmacognostic analysis of plant materials was carried out. And also indicators were established by which it is necessary to evaluate the quality of the tincture obtained on the basis of the selected plant raw materials (the content of thymol, extractives, etc.).

Experimental tests of the preparation have shown a high efficiency of the action on the tick.
