Abstract

The utility model relates to beekeeping, in particular, to the diagnosis of the degree of damage to bees by the mite Varroa destructor. The device includes two containers installed one above the other, placed with their necks towards each other. The necks are interconnected by a tube with a calibrated mesh placed in it, which is made with the possibility of removing it from both necks of the containers.

Description

The utility model relates to beekeeping, in particular, to the diagnosis of the degree of damage to bees by the mite Varroa destructor.

It is important to determine the infestation of bees by mites in late autumn, which makes it possible to assess their condition and largely determines the results of hibernation of bee colonies. The calculation is carried out for 100 bees: weak - up to 2, medium - up to 4, strong - over 4. Research is carried out in this way. 2-3 g of washing powder or soda are added to a cup with a white bottom, a glass of hot water is poured, a sample of bees is added and stirred for 1-2 minutes. Fallen ticks are clearly visible on a white background. The more bees taken in the sample, the more accurate the result of ticking. But the disadvantage of the method is that the bees die with this method. The method is not widely used for a simple reason: beekeepers feel sorry for living bees, especially in the autumn, when these bees have to go into wintering. There is a way when they simply look at the bees with a magnifying glass. But this method is not accurate, because many mites are hidden under the tergites or sternites of the bees and are not visible.

A device for determining the degree of damage to bees is known, which includes a glass funnel with a lid and a glass outlet pipe at the time the bee passes through the glass pipe, the presence of mites on it is determined (SU 1663796). The disadvantage of this device is the low speed of determining the presence of mites on the bees and the large expenditure of time, since each individual is subject to inspection.

The closest in its technical essence is a device for determining the degree of damage to bees by tick infestation, including containers made of transparent material and installed one above the other (SU 1122283, 06/07/1984).

The disadvantage of this device is that the bees have to be immobilized before counting ticks on them, which leads to injury to individual individuals. In addition, this work requires the presence of large labor costs and the presence of a person during their visual inspection.

The task solved by this utility model is to save the life of the studied bees and reduce the complexity of the process of determining the degree of damage to bees by tick infestation.

The technical essence lies in the fact that the count of mites parasitizing on bees is carried out after they leave the live bees.

This problem is solved by the fact that in the device for determining the degree of damage to bees by tick infestation, which includes two containers installed one above the other, the containers are installed with necks towards each other, the necks are interconnected by a tube with a calibrated mesh placed in it, while the tube is made with the possibility of removal it from both necks of containers.

In FIG. 1 shows a diagram of a device for collecting ticks from honey bees in order to determine the degree of their tick invasion.

In FIG. 2 shows a calibrated grid placed in a pipe.

The device consists of a container for fallen mites 1, a container for bees 2. The containers 1 and 2 are connected to each other by a tube 3 with a mesh 4 placed in it. The tube 3 is attached to the necks of the containers 1 and 2 with the possibility of removing it from them. The calibrated mesh 4 has a mesh size smaller than the size of bees, but larger than the size of mites.

The device works as follows. In container 2 shake the bees from the honeycomb frames of the hive. A dose of any acaricidal preparation is added to the container and a container 2 is attached to the tube 3 on the neck of the container 2. The device is turned into a vertical position with container 2 to the top. Leave for a while (the time of action of the added acaricidal preparation). You can use a heat chamber to scree ticks. To do this, the whole device is placed in a heat chamber with a temperature of 47 degrees Celsius for 15 minutes. The mites, falling off the bees through the holes in the grid, fall into container 1. At the end of the procedure, the bees are released into the hive, and the number of mites is counted.

The process of counting bees in a sample is laborious. To speed up this process, an experiment is carried out: container 1 is weighed with bees and without bees and the bees in the sample are counted. Then the total weight of the bees is divided by the number of bees and the mass of one bee is calculated. This average value is used in subsequent experiments. To determine the number of bees in a sample, container 1 with bees is weighed, the weight of container 1 is subtracted and divided by the mass of one bee.

Advantages of the proposed utility model:

- bees remain alive after the experiment;

- a large number of bees that return to the bee colony can be used to determine the tickiness, which increases the accuracy of determining the tickiness of bee colonies in the apiary.

- no need to manually count the number of bees. The degree of damage to bees is determined by the formula:

,

,

where n is the number of ticks;

m is the number of bees.
