Invent with a host to a family farm, specifically beekeeping, and can be used to control the swarming of bees, to enhance their flight activity, to control the bee erostomatosis, to select a bee, and the like.

The purpose of the invention is to increase the number of methods and devices.

FIG. 1 shows a functional diagram of the device; n & FIG. 2 - voltage pulse diagrams.

The method of activating the motor activity of bees provides that the F volume of the ul excites electric water with a predetermined frequency and intensity. The field delivery mode is carried out with regressive periods of time during which the floor is turned on, and pauses between them, during which the field is turned off, stimulated motor and sonic gk-tmviset bees, the duration of the spacing of the time during which the floor is switched on, and the pauses during which the field is turned off, are corrected with. through feedback on the sound of bees. This adjustment is implemented as follows. Gradually increasing the duration of the ROL, determines the maximum sound activity of the bees, turns off the priest and determines the duration of the pause between the maximum time and the i-interval between the maximum acoustic activity of the bees or slightly less than this and the decrease of this a-elitude to the specified value. after the field is higher, turn on the field and determine the duration of the field, the radial time interval between the above specified value of the bees' sound activity and the increase of this value to the maximum or a few less than the magnitude of the sound activity of bees.

The device for the activation of the motor activity of bees contains a generator of voltage pulses 1, to the control input (control) of which is attached a light control 2, high power 3 w grounding electrodes 3 l 4, installed

on opposite sides of the ul 5 and connected to the high potential and grounding terminals of the voltage pulse generator, control unit 2

made as a series-connected acoustic sensor 6 of the movement activity of bees, for example, a microphone acoustically connected with the volume of ul 5, amplifier 7, detector 8 and comparator 9,

For example, the Schmitt trigger whose output (the output of control unit 2) is connected to the control input of a voltage pulse generator is connected electrically to a detector 8, the recorder 10, designed

to record the acoustic level of motor activity

The method is carried out with the following cut.

With the help of a high potential and high potential generator; grounding electrodes 3,4s volume of ul 5 excite an alternating electric field, the intensity and frequency of which are set, for example: E - 1, bv and d

500 Hz. The dependence of the intensity E of the electric field or the time T and the dependence of the sound active) and K of the bees (the detected signal from the output of the detector 8, coming to the comparator 9) from

Time T is shown in FIG. 2 (Diagrams 11 and 12) Namin from time T0 0 turn on the generator and the voltage of the field of the R & P 5 and the small field, and as a result, it starts; - the activation of the motor activity lchel, expressing, and in particular, elevation of their motor activity and correlated with it sound activity. After switching on the field over time (the section To - Ti, FIG. 2, plot 12} the level of sonic activity K of the bees increases and reaches the maximum Cmax (reaching the level QoHSMbGT, i: ro with a further increase in the duration of

the magnitude of the bees sound activity does not increase). Having determined the value of Kmax, set the upper threshold of the Kzill trigger (turn off the comparator 9 and its

the lower threshold for the operation (turn on), e.g. - 0.9 Kmaks and KVKl. - 3 Cmax. After setting the values of Kvykl and Kakl, the device operates in an automatic mode with feedback from the sound made by the bee colony: the comparator 9 is activated by turning off the generator 1 of voltage pulses at times TI, Tz, Ts, ..., etc. and including a voltage pulse generator 1 at times Ta, T4, Te, ..., etc. By filming this in more detail,

After switching off the floor, the motor activity of the bees and the sound background of the ul 5 gradually decrease (time Ti-T2), and since the lower threshold for switching on the comparator 9 is set at the Köhl level, the latter is turned on, as a result of which the voltage pulse generator 1 starts and in the volume of ul 5 an electric field is again created with a given intensity Eo (Fig. 2, section T.T.z.) and again the level of sound activity of the bees begins to increase (the time interval Ta-Tz on the plot 12 of Fig. 2). But as soon as the sound level of the ul 5 reaches the value of Kvikl, the comparator 9 turns off, again turn off the voltage pulse generator 1 and the field in the volume of ul 5. 8 the process described below repeats (time intervals TZ-TS, hooked field, intervals are baptized ,. .. pause or field off i / i etc.

Thus, the duration of each of the intervals during which the field is turned on (sections t2-Tz. T / i-Tg ,,.) And each of the intervals for which the field is turned off is Peusa (sections Ti-T2, Tz-T / i ...), are determined by the duration of the time interval between the set level Kvikl of the sound activity of bees and the decline of this level by a certain predetermined value, |

set using adjustments in computer 9.

An example. The wads were carried out with the family occupying 14 frames of the Ul 5 - a plank bed in order to stimulate the flight test flight. Flat electrodes 3, A were installed from two opposite storums ul and connected to the output of the ayss-voltage switch on the generator 1 pulses. After switching on the generator 1 at the specified intensity values (E 1.5 -104 V / m and frequency F 550 Hz, the duration T of the floor was determined at which the bees reached the maximum Kmax of sound activity. For a family, TI 26 turned out to be , Kmaks - -4,8B (in relative units). After

determinations of Ti and Kmax set the upper and lower thresholds for the operation of comparator 9, respectively Kvykl 0.9 Kmaks 4.3 V and Kvkl 0.4 K max 1.9 V. After installation

The comparator tripping thresholds obtained average values of time intervals during which the field was turned on: TBCL. 10 s, duration of pauses Tpauz 5 s. So for each particular

the bee colony automatically feedbacks the sound of the bees to set the minimum duration of the field sufficient for the required activation (required excitation)

bees, and the maximum duration of the pauses, not leading to a decrease in their activity below the permissible value.

When using the invention, an optimal mode of bee stimulation is provided; the conditions of over-excitation of the bee colony are eliminated when, even at the achieved value of the motor activity of the bees, the field continues to remain switched on; carried out

automatic setting of the pause duration, allowing, in accordance with the specific rules of the method of activating the bees, to select, combat the airborne carcinoma, eliminate the swarm swarm, etc., and choose the optimal time to calm them down; a reduction in the adaptation of bees to the electric field is achieved, with the result that the high average level of their excitation is maintained for a longer time; There is considerable energy savings due to the choice of optimal time intervals during which the field is turned on and off.
