To verify the mite removing effect of the mite removing instrument of the present application, the applicant performed the following experiments:

selecting ten beehives with similar bee colony situation in a bee field, recording as a beehive I, a beehive II … … beehive ninth and a beehive ten, and selecting and observing about 30% of bee mite parasitic rate in each beehive by an applicant before an experiment, wherein the bee mite parasitic rate is the number of bees with mites/the total number of detected bees.

Wherein:

two mite removing instruments are arranged in the first beehive and the second beehive, meanwhile, the anion generator 21 of the mite removing unit 2 in each mite removing instrument is provided with four anion emitting heads 211, the concentration of anions released by the electric brush heads 212 of each anion emitting head 211 is about 500 ten thousand per cubic centimeter, the ultrasonic frequency is about 40kHz, and the magnetic field frequency is about 5 kHz.

And the third beehive and the fourth beehive are used for removing mites through a No. 1 miticide, the miticide is mixed with water to prepare a liquid medicine, the liquid medicine is filled into a sprayer after being fully stirred, and then the liquid medicine is uniformly sprayed on bee bodies of honeycomb spleens, so that the bee mites are poisoned and fall off the bee bodies in about 30 minutes.

And the fifth beehive and the sixth beehive are subjected to mite killing by a No. 2 mite killing paper smoke agent, after the bees return to the nest at evening, a nest door is tightly closed, a box cover is opened to ignite one corner of the medicine bag, the medicine bag is rapidly placed into the box, the box cover is tightly closed, after smoking is carried out for 15-20 minutes, the nest door is opened, and residual ash is taken out.

The seventh beehive and the eighth beehive fix the mite-killing sheets between the bee ways through the thumbtack to continuously remove the mites.

And 4, carrying out no mite removal treatment on the ninth beehive and the tenth beehive until the bee brood spleens are hatched, and then observing.

In addition, a flat plate is laid at the bottom of each beehive, single-sided glue is arranged on the flat plate, and one side of the single-sided glue faces upwards so as to facilitate mite collection observation.

Because the time that different mite modes of removing took effect is different, especially the mite tablet need use for a long time just can play better curative effect, so time does not regard as specific consideration element in the experiment, only compares with the son spleen hatchability and bee mite parasitic rate when the son spleen is complete hatching after removing the mite, also can assist and compare the mite effect of removing through observing the collection mite volume on the single face glue simultaneously. The hatching rate of the neutron spleen is the hatching number of the young bees/the total number of the capped young bees.

Table 1 comparison of the parasitic rate of bee mites, brood spleen hatching rate and mite collection amount after mite removal of each beehive:

beehive	Parasitic rate of bee mites (%)	Hatching rate of spleen (%)	Mite-collecting amount
				Beehive 1	3.2％	98.7％	Dense packing
Beehive II	2.5％	98.6％	Dense packing
				Beehive III	0.3％	77.6％	Is extremely dense
Beehive four	0％	67.3％	Is extremely dense
				Beehive five	0.8％	82.3％	Dense packing
Six beehives	1.2％	85.7％	Dense packing
				Seven beehives	1.4％	92.6％	Dense packing
Eight beehives	2.1％	91.2％	Dense packing
				Nine beehives	39％	57.2％	/
Beehive ten	36％	55.3％	/

After the experiment, the applicant finds that the mite removing instrument has the function of removing mites, and the applicant finds that most of bee mites adhered to the single-sided glue are alive mites. The applicant believes that although the mite killing efficiency of the mite killing instrument is slightly lower than that of some medicament mite killing modes, the effect of the mite killing instrument on bees is also low, and particularly the brood comb of the bees is nearly not affected, so that the hatching rate of the brood comb of the bees can be kept at a higher level.

With reference to fig. 5 and 6, the applicant believes that the principle of implementation of the mite-killing apparatus may be as follows:

as the surface of the bee 8 is provided with fine villi, in the outgoing honey collection process of the bee 8, the high-frequency stretching and contraction of the pectoralis muscle of the bee 8 flies in a way of vibrating 160 and 240 wings per second, and high-speed friction is generated with air while energy is consumed, so that positive charges on electrons are lost.

After the honey collection of the bees 8 is finished, the negative ions are emitted due to the magnetic field, the negative ions are combined with oxygen in the air to form negative oxygen ions, the other part of the negative ions directly exist in an independent body of electrons, and the negative oxygen ions and the electrons can be combined with positive charges on the bees 8 to generate potential voltage, so that current is generated on the body surfaces and the bodies of the bees 8. Because the bee mites 7 are small in size and low in tolerance to current, the bee mites 7 are shocked by electricity to stun or attack numb, so that the bee mites cannot be attached to the body surfaces of the bees 8 to knock down the bee mites 7. The bee mites 7 are not killed directly, but hit the bottom of the hive 5, so most of the mites are live mites seen on the single-sided glue. The body type of the bee 8 is larger than that of the bee mite 7, and the current cannot influence the bee 8.

Simultaneously because bee mite 7 does not tolerate the ultrasonic wave, bee mite 7 can crawl everywhere under the influence of ultrasonic wave, and then climbs out to the bee way and look for honeybee 8 parasitism from the depths of honeycomb. When the bee mites 7 pierce chitin or tunica between the bees 8 and want to absorb hemolymph in the bee 8 body, pressure difference is generated between the bee 8 body surface and the body, so that electric current is generated to knock down the bee mites 7. In addition, the sound of the bee 8 can only be heard within 440Hz, so the bee is not sensitive to high-frequency ultrasonic waves and cannot be influenced by the ultrasonic waves.

To further verify the effect of ultrasonic frequency on bee mites 7.

The applicant also selected a plurality of beehives 5 of the same bee field for verification and adjusted the ultrasonic frequency, and the bee mite parasitism rate of each beehive 5 is about 30% before the experiment is started.

The first embodiment is as follows:

the number of the mite removing units 2 is two, each mite removing unit 2 is provided with four negative ion emitting heads 211, the concentration of negative ions released by electric brush heads 212 of each negative ion emitting head 211 is about 500 ten thousand per cubic centimeter, the frequency of ultrasonic waves is set to be about 20kHz, the frequency of a magnetic field is set to be about 5kHz, and the mite removing time is set to be 24 hours.

Example two:

the difference from the first embodiment is that the ultrasonic frequency is set to about 25 kHz.

Example three:

the difference from the first embodiment is that the ultrasonic frequency is set to about 30 kHz.

Example four:

the difference from the first embodiment is that the ultrasonic frequency is set to about 34 kHz.

Example six:

the difference from the first embodiment is that the ultrasonic frequency is set to about 40 kHz.

Example seven:

the difference from the first embodiment is that the ultrasonic frequency is set to about 45 kHz.

Example eight:

the difference from the first embodiment is that the ultrasonic frequency is set to about 50 kHz.

Example nine:

the difference from the first embodiment is that the ultrasonic frequency is set to about 60 kHz.

Comparative example one:

the difference from the first embodiment is that the ultrasonic frequency is set to about 10 kHz.

Comparative example two:

the difference from the first embodiment is that the ultrasonic frequency is set to about 15 kHz.

Comparative example three:

the difference from the first embodiment is that the ultrasonic frequency is set to about 65 kHz.

Comparative example four:

the difference from the first embodiment is that the ultrasonic frequency is set to about 70 kHz.

Comparative example five:

the difference from the first embodiment is that the ultrasonic generator 22 is not provided.

And (3) performance detection:

bee mite parasitism rate tests were carried out on the first to ninth examples and the first to fifth comparative examples, and the test results are shown in the table:

table 2 examples one to nine and bee mite infestation rate measurements of comparative examples one to five:

testing	Parasitic rate of bee mites (%)
		Example one	3.7％
Example two	3.7％
		EXAMPLE III	2.6％
Example four	2.7％
		EXAMPLE five	3.5％
EXAMPLE six	2.5％
		EXAMPLE seven	2.9％
Example eight	2.2％
		Example nine	4.6％
Comparative example 1	9.7％
		Comparative example No. two	8.6％
Comparative example No. three	7.9％
		Comparative example No. four	8.2％
Comparative example five	10.2％

As can be seen from the table, in the first to ninth examples, the mite removing efficiency of the mite removing instrument is better than that of the first to fifth comparative examples, and the applicant sets a camera in the beehive to observe that no abnormality occurs in the behavior of the bees in each beehive.

The applicant believes that the reason why bee mite 7 does not tolerate ultrasonic frequencies of 20kHz to 60kHz may be as follows: the ultrasonic frequency of 20kHz-60kHz is the ultrasonic frequency band used for positioning by the bats, most nocturnal insects can evolve a special auditory organ for avoiding the predation of the bats and can capture the ultrasonic wave of the frequency band, although the bee mites 7 are not the insects predated by the bats, the bee mites 7 also have the auditory organ capable of hearing the frequency band, and therefore the bee mites 7 can generate an approach phenomenon after hearing the ultrasonic wave of the frequency band so as to climb around, namely climb out from the deep part of the honeycomb to arrive at the bee road and further be more easily attacked by negative ions.

Meanwhile, the applicant observes the phenomenon of mite dropping and finds that different bee mites have certain difference in sensitivity to ultrasonic waves of different frequency bands, for example, the parasitic rate of the small bee mites is lower when the frequency bands are 30kHz and 34kHz, and the proportion of the small bee mites is higher when the frequency bands are dropped; at 40kHz and 50kHz, the parasitism rate of varroa jacobsoni is lower, and the proportion of varroa jacobsoni is higher when the varroa jacobsoni falls.

Therefore, to further verify the better mite killing effect of the mite killing instrument, the applicant further performs the following setting: example ten:

the number of the mite removing units 2 is two, each mite removing unit 2 is provided with four negative ion emitting heads 211, the concentration of negative ions released by electric brush heads 212 of each negative ion emitting head 211 is 500 ten thousand per cubic centimeter, the frequency of a magnetic field is 5kHz, the frequencies of ultrasonic generators 22 in the two mite removing units 2 are respectively set to be 30kHz and 40kHz, and the mite removing time is set to be 24 hours.

Example eleven:

the difference from the tenth embodiment is that the frequencies of the ultrasonic generators 22 in the two mite removing units 2 are set to 30kHz and 50kHz, respectively.

Example twelve:

the difference from the tenth embodiment is that the frequencies of the ultrasonic generators 22 in the two mite removing units 2 are set to 34kHz and 40kHz, respectively.

Example thirteen:

the difference from the tenth embodiment is that the frequencies of the ultrasonic generators 22 in the two mite removing units 2 are set to 34kHz and 50kHz, respectively.

And (3) performance detection:

bee mite parasitic rate detection is carried out on the ten to thirteen examples, and the detection results are shown in the table:

table 3 example ten to thirteen bee mite infestation rate measurements:

as can be seen from the table, when the frequencies of the ultrasonic generators 22 in the two mite removing units 2 are respectively set to be 30kHz and 50kHz, the two ultrasonic waves do not generate great interference influence, the mite removing effect on the large bee mites and the small bee mites is better than other frequencies, meanwhile, the ultrasonic frequencies at 34kHz and 40kHz can also play a better effect on the large bee mites and the small bee mites, the mite removing effect of the mite removing instrument 6 under the frequencies is not worse than the mite removing effect of the medicament, and meanwhile, the mite removing instrument is harmless to the son spleens of bees.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
