Description

The present invention relates to a method for detecting a beehive in a search space including an area invisible due to a shield.

In outdoor work such as weeding in grass, bushes where trees coexist, and grass unevenness (hereinafter collectively referred to as "grass unevenness"), the nest is stimulated by chance without noticing that bees are nesting in the work place. And may be bitten. To prevent bee sting damage, it is effective to wear bee sting protective clothing. However, outdoor work wearing a bee sting suit is not only obstructing the worker's view and restricting their behavior, but also the temperature inside the suit rises considerably, which makes the work longer. It is difficult to continue the time. Therefore, it is desirable to wear a bee sting protective suit before starting the outdoor work to exterminate the beehive in a short time, and then take off the bee sting protective suit to carry out the outdoor work.

Conventionally, a method using an aerosol product for exterminating beehives has been known. For example, Patent Document 1 describes a bee control method that directly sprays an aerosol agent onto a beehive to exterminate bees in the nest and prevents bees that have escaped extermination from returning to the nest. It is disclosed.

Patent Documents 2 and 3 disclose a method for exterminating bees by applying a composition containing monfluorotrin as an active ingredient to a habitat of bees.

However, the bee control method disclosed in Patent Document 1 assumes nesting in a building such as a house, and presupposes that the nesting location can be confirmed in advance. The methods for exterminating bees in Patent Documents 2 and 3 are also based on the premise that the habitat of bees has been confirmed.

In outdoor work, the line of sight is blocked by grass, trees, etc., and it may be difficult to detect the nesting site or even detect its existence. For example, the giant hornet often nests near the ground or in the ground, but in weeding work where the overgrown grass is the work place, the vicinity of the ground cannot be seen due to the dense grass, so it is very difficult to detect the existence of the nest. Have difficulty. This, combined with the danger of the giant hornet, can cause serious damage.

The present invention has been made in view of the above problems, and is a method for detecting a beehive that can specify the presence or absence of a beehive and its nesting location in a search space including an area that cannot be seen by a shield. The purpose is to provide.

The characteristic configuration of the honeycomb detection method according to the present invention for solving the above problems is
A method of detecting a beehive in a search space that includes an area that cannot be seen due to a shield.
In the search space, the first step of spraying the bee excitement-inducing composition and
The second procedure is to set a shield located in the vicinity of the bee that appears in the visible area in response to the sprayed excitement-inducing composition of the bee, or an area that cannot be seen by the shield as a nesting place for the bee. ,
Including,
The amount of the bee excitement-inducing composition sprayed is such that the bee does not exhibit the knockdown symptomatology and becomes excited.

According to the method for detecting a beehive in this configuration, when a beehive is present in the search space, the bees in the nest become excited without knocking down due to the spraying of the excitement-inducing composition of the bees. Fly from. Even if the nesting location is in an invisible area, it is possible to observe the flying bees, so that the existence of the beehive can be easily detected and the nesting location can be specified. As a result, it is possible to avoid accidentally stimulating the nest and suffering bite damage without noticing the beehive in the search space.

In the method for detecting a beehive according to the present invention,
The bee excitement-inducing composition contains a pyrethroid-based active ingredient and contains.
The bee excitement-inducing composition in the first procedure is sprayed by injecting the detection aerosol agent from an aerosol in which a detection aerosol agent containing the excitement-inducing composition and a propellant is sealed in a pressure-resistant container. It is preferable to carry out.

According to the method for detecting the honeycomb of the present configuration, since the excitement-inducing composition of the bee contains a pyrethroid-based active ingredient, a good excitement-inducing effect can be obtained. In addition, by using an aerosol, the bee excitement-inducing composition can be easily and widely sprayed. As a result, the presence or absence of a beehive in the search space can be easily confirmed.

In the method for detecting a beehive according to the present invention,
The pyrethroid active ingredient contains at least monfluorotrin and contains at least monfluorotrin.
The injection amount of the sensing aerosol agent in the first procedure is preferably adjusted to ^{0.2 to 50 mg / m 2 as the amount of the monfluorotrin.}

When the spray amount of the detection aerosol agent is 0.2 to 50 mg / m ² as the amount of monfluorotrin, the number of bees exhibiting knockdown symptoms in the nest can be suppressed. Therefore, a sufficient number of bees fly out of the nest, and the existence of the beehive is not missed. As a result, most of the bees showed knockdown symptoms in the nest, so they failed to detect the existence of the beehive, and some bees that did not show knockdown symptoms when they accidentally approached the nest caused bite damage. You can avoid receiving.

In the method for detecting a beehive according to the present invention,
It is preferable to further include a third procedure of spraying the bee insecticidal composition around the site designated as the nesting site of the bee in the second procedure.

According to the beehive detection method of this configuration, if there is a beehive in the search space, even if the nesting site is in an invisible area, the presence of the beehive by the execution of the third step The third procedure can be performed in a short time, and the bees in the nest can be easily exterminated.

In the method for detecting a beehive according to the present invention,
The bee insecticidal composition contains a pyrethroid-based active ingredient and contains.
The spraying of the bee insecticidal composition in the third procedure is carried out by injecting the insecticidal aerosol agent from an aerosol in which an insecticidal aerosol agent containing the insecticidal composition and a propellant is sealed in a pressure-resistant container. Is preferable.

According to the method for detecting a beehive having this configuration, since the bee insecticidal composition contains a pyrethroid active ingredient, a good insecticidal effect can be obtained. In addition, the bee insecticidal composition can be quickly sprayed around the bee nesting site using an aerosol. As a result, the bees in the nest can be easily exterminated.

In the method for detecting a beehive according to the present invention,
The injection amount of the insecticidal aerosol agent in the third procedure is preferably set as the amount of the pyrethroid active ingredient, which is larger than the injection amount of the detection aerosol agent in the first procedure.

According to the beehive detection method of this configuration, a sufficient number of bees are allowed to fly from the nest by suppressing the number of bees exhibiting knockdown symptoms when the detection aerosol agent is sprayed, and the nest is when the insecticidal aerosol agent is sprayed. It is possible to exterminate bees in the nest while avoiding being bitten by knocking down the bees flying in the vicinity of the nest and the bees in the nest.

In the method for detecting a beehive according to the present invention,
The pyrethroid active ingredient is preferably at least one selected from the group consisting of monfluorotrin, d-T80-resmethrin, d-T80-phthalthrin, and d.d-T80-praletrin.

According to the method for detecting a beehive having this configuration, since the above-mentioned appropriate active ingredient of the pyrethroid system is used, a good excitement-inducing effect and an insecticidal effect can be obtained.

In the method for detecting a beehive according to the present invention,
It is preferable to use the same composition as the bee excitement-inducing composition and the bee insecticidal composition.

According to the beehive detection method of this configuration, the work from the detection to the extermination of the beehive using a single type of composition is only required by changing the spraying method, spraying amount, etc. according to the application. Can be carried out. Therefore, it is not necessary to determine the amount to be carried into the work site in consideration of the amounts of the bee excitement-inducing composition and the bee insecticidal composition used, and it is possible to avoid a situation where only one composition is insufficient at the work site. be able to.

In the method for detecting a beehive according to the present invention,
The shield located in the vicinity of the bees appearing in the visible area is preferably a shield located at the flight source of the bees appearing in the visible area.

According to the beehive detection method of this configuration, the nesting location of the bees can be accurately identified from the flight path of the flying bees. As a result, it is possible to avoid accidentally stimulating the nest and suffering bite damage by misidentifying the nesting location.

FIG. 1 is an explanatory diagram of a method for detecting a beehive according to the present invention. FIG. 2 is a flowchart of a beehive detection method according to the present invention.

Hereinafter, embodiments relating to the method for detecting a beehive of the present invention will be described with reference to FIGS. 1 and 2. However, the present invention is not intended to be limited to the configurations described in the embodiments and drawings described below.

The method for detecting a beehive according to the present embodiment is a search space (for example, a bush where grass and trees coexist, grass unevenness, etc.) including an area that cannot be seen due to a shield (for example, grass, trees, etc.). It is used to detect the existence of the bee and identify its nesting site. When carrying out outdoor work such as weeding work, if the presence or absence of a beehive in the search space is detected in advance and the nesting location is specified, the nest is accidentally stimulated and bitten without noticing the beehive. You can avoid being damaged. When the existence of a beehive is detected, the damage caused by biting can be reduced by refraining from approaching the nesting site or, preferably, exterminating the bees in the nest where the presence is detected.

The bees to be detected in the nest include hornets such as Futamon hornet, seguro hornet, and paper wasp, hornet, hornet, Japanese giant hornet, giant hornet, hornet, hornet, and other hornets. Bees are mentioned.

FIG. 1 is an explanatory diagram of a method for detecting a beehive according to an embodiment of the present invention. FIG. 2 is a flowchart of a beehive detection method according to an embodiment of the present invention.

FIG. 1A shows a state in which the worker 1 performs weeding work in the work space S. In the work space S, there is grass unevenness in which tall grass is densely grown, and in the area H shaded by the alternate long and short dash line corresponding to the plant height, the grass acts as a shield to block the line of sight from the worker 1. It is an invisible area (hereinafter, "shielded area"). For example, in the shielded area H, even if the giant hornet nest 2 exists near the ground, the worker 1 cannot visually recognize its existence. In this state, the worker 1 may approach the nest 2 without noticing it and suffer a bite damage.

Therefore, in the method for detecting a beehive according to the present embodiment, before performing the weeding work, the work space S is used as a search space for the beehive, and the existence of the beehive is detected by the procedure shown in FIG. 2, preferably. , Exterminate the bees in the beehive that you have detected. In implementing the beehive detection method according to the present embodiment, the worker first wears a bee bite protective clothing (step S1). Then, the bee excitement-inducing composition is sprayed on the grass in the search space S (step S2). As shown in FIG. 1 (b), it is preferable to use the sensing aerosol product 3 for spraying the bee excitement-inducing composition.

The detection aerosol product 3 is configured as a pressure-resistant container 4 in which a detection aerosol agent containing a bee excitement-inducing composition, an organic solvent, and a propellant is sealed. In preparing an aerosol for detection, in consideration of workability, an aerosol stock solution is first prepared by dissolving a bee excitement-inducing composition in an organic solvent. Then, this aerosol stock solution is sealed in the pressure-resistant container 4 together with the propellant.

The bee excitement-inducing composition preferably contains a pyrethroid-based active ingredient. Examples of pyrethroid active ingredients are monfluorothrin, d-T80-allethrin, d-T80-phthalthrin, d.d-T80-praletrin, cyfluthrin, phenothrin, cyfluthrin, permethrin, tralomethrin, bifenthrin, deltamethrin, shirafluofen, et. Etofenprox, imiprothrin, cypermethrin, empentrin, transfluthrin, metoflutrin, profluthrin, terraresrin, allethrin, prarethrin, pyrethrin, imiprothrin and the like can be mentioned. In particular, in the bee excitement-inducing composition, at least monfluorothrin, d-T80-phthalthrin, and d.d-T80-praletrin are contained as one of the active ingredients, and one or more of them are contained. It is more preferable to use in combination. Further, when optical isomers or geometric isomers are present in the molecular structure of the pyrethroid insecticidal component, they are also included in the present invention.

The aerosol stock solution contains an organic solvent capable of dissolving the bee excitement-inducing composition. An aerosol stock solution is prepared by dissolving the bee excitement-inducing composition in an organic solvent. Since the characteristics of the organic solvent affect the formation of spray particles when the sensing aerosol agent is sprayed, those adjusted to an appropriate viscosity are used. The viscosity of the organic solvent is preferably less than 10 mPa · s at 20 ° C., more preferably less than 5 mPa · s. Examples of organic solvents that can be used to prepare the aerosol stock solution include normal paraffin, hydrocarbon solvents such as isoparaffin, alcohols such as ethanol, isopropanol and n-propanol, propylene glycol, 1,3-butylene glycol, 1, Examples thereof include glycols such as 4-butylene glycol and dipropylene glycol, glycol ethers such as diethylene glycol monobutyl ether, ketone solvents, ester solvents and the like. The above-mentioned organic solvents are not limited to use alone, and two or more kinds may be used in combination.

The aerosol stock solution can be prepared as an aqueous aerosol agent by blending water, and in this case, a surfactant is added as needed. Examples of surfactants include polyoxyethylene alkyl ethers, polyoxyethylene alkyl phenyl ethers, polyoxyethylene polyoxypropylene alkyl ethers, ethers such as polyoxyethylene alkyl amino ethers, polyethylene glycol fatty acid esters, etc. Nonionic surfactants such as polyoxyethylene sorbitan fatty acid esters, polyoxyethylene glycerin fatty acid esters and other fatty acid esters, polyoxyethylene styrene phenol, and fatty acid polyalkalolamide, polyoxyethylene (POE) styryl Examples thereof include anionic surfactants such as phenyl ether sulfate, polyoxyethylene (POE) alkyl ether sulfate, and dodecylbenzene sulfate.

As the propellant, a gaseous one is used at normal temperature and pressure in order to vigorously inject the aerosol stock solution into particles. In addition, the propellant is required to have stability in the pressure vessel so as not to alter the excitement-inducing composition of the bee. Examples of such propellants include liquefied petroleum gas (LPG), dimethyl ether (DME), nitrogen gas, carbon dioxide gas, nitrous oxide gas, compressed air and the like. Of these, LPG and nitrogen gas, which are easily available and easy to handle, are preferably used. The above-mentioned propellants are not limited to use alone, and two or more of them may be used in combination.

The propellant is adjusted so that the volume ratio (a / b) of the aerosol stock solution (a) and the propellant (b) is 40/60 to 80/20. If the volume ratio (a / b) is smaller than 40/60, the propellant becomes excessive, so that the relative amount of the aerosol stock solution filled in the pressure-resistant container becomes small, and one detection aerosol product 3 is used for bees. The area where the excitement-inducing composition can be sprayed is narrowed, which may reduce work efficiency. If the volume ratio (a / b) is larger than 80/20, the propellant is insufficient, so that the bee's excitement-inducing composition reaches a short distance due to the jet, and the worker 1 does not notice until the worker 1 approaches the nest 2. There is a fear. When the volume ratio (a / b) is adjusted to the above-mentioned appropriate range, the internal pressure of the aerosol agent in the pressure-resistant container is 0.25 to 0.70 MPa (25 ° C.).

As the detection aerosol product 3, for example, "Hunter Z PRO 510 mL for bees and bugs, which is also effective against wasps" manufactured by Dainihon Jochugiku Co., Ltd. can be used.

By injecting the detection aerosol agent using the detection aerosol product 3, even a hardly volatile substance such as monfluorotrin can be quickly and widely sprayed. Among the pyrethroid active ingredients, monfluorotrin has a high effect of stopping flight on bees, and aerosol products containing monfluorotrin as an active ingredient in an aerosol agent are generally sprayed directly on bees to exterminate them. Is often the expected product. However, the spray amount of the detection aerosol agent should be adjusted so that the spray amount of the excitement-inducing composition of the bee is such that the bee does not exhibit the knockdown symptom and becomes excited. So you can avoid killing the bees in the nest. By injecting in such an amount, bees (5a, 5b) come out of the nest 2 as shown in FIG. The behavior of jumping out to the area where it can be made and flying is seen. This confirms the existence of the beehive.

The "amount of the bee that does not exhibit knockdown symptoms and becomes excited" varies depending on the active ingredient. For example, when the active ingredient contained in the bee's excitement-inducing composition is monfluorotrin, an aerosol for detection is used. the injection amount of agent, 0.2 to 50 mg / ^{m 2} as the amount of Mont fluoro Trindade, preferably by adjusting the 2~30mg / ^{m 2,} the effective amount of bees is excited not exhibit knockdown symptoms Ingredients can be sprayed. Specifically, when using Dainihon Jochugiku Co., Ltd.'s "Hunter Z PRO 510 mL for bees and abs, which is also effective against wasps" for spraying the excitement inducer of bees, in order to achieve a suitable injection amount, It is preferable to use two aerosol products for a search space having an area of about 100 m ^2.

In the method for detecting a beehive according to the present embodiment, when the bee (5a, 5b) flies out of the nest 2 as shown in FIG. 1 (c) after spraying the bee excitement-inducing composition, it is visually recognized. The appearance of bees (5a, 5b) in the formed area is confirmed (step S3: Yes in FIG. 2). When the appearance of the bees (5a, 5b) in the visible area is confirmed, the grass (6a, 6b) located in the vicinity of the observed bees (5a, 5b) or the grass (6a, 6a, The area that cannot be seen by 6b) (the area surrounded by the thick line in this figure) is designated as the nesting place N of the bees (step S4 in FIG. 2). The appearance of the bee in the visible area may be observed by the operator in charge of spraying the excitement-inducing composition of the bee, or may be observed by another operator. An optical device such as a camera or binoculars may be used for observing the appearance of bees in a visible area. In particular, when a worker different from the worker in charge of spraying the bee excitement-inducing composition is in charge of observation, the worker in charge of observation should observe from outside the search area S using an optical instrument. Therefore, it is possible to avoid suffering from bite damage. Further, the appearance of the bee in the visible area is not limited to the visual confirmation of the bee, but may be confirmed by an image recorded using a video camera, a still camera or the like. In order to more accurately limit the nesting location of bees, it is preferable to identify the grasses (6a, 6b) located at the flight source by observing the flight path of the bees (broken line in FIG. 1C). .. To confirm such a flight path, it is possible to apply confirmation using an image recorded using a video camera, a still camera, or the like.

In this way, even if it is unknown whether or not a beehive exists in the search area S, by invading the search area S while spraying the excitement-inducing composition of the bee and observing the flight of the bee. , The existence of the nest can be detected. Further, when the bee does not appear in the visible region even after the bee excitement-inducing composition is sprayed in step S2 of FIG. 2 (step S3: No), the bee is placed in the search space S where the bee excitement-inducing composition is sprayed. It can be confirmed that there is no nest.

In the method for detecting a beehive according to the present embodiment, it is preferable to spray the bee insecticidal composition to the beehive nesting site N (step S5 in FIG. 2) after detecting the beehive. As a result, the bees 5c remaining inside the nest 2 can be killed without taking off even after spraying the bee excitement-inducing composition. At that time, the insecticidal composition may be sprayed not only at the bee nesting site N but also around the bee nesting site N. As a result, even if the actual beehive is located at a position slightly deviated from the place where the bee nests N, the bees 5c remaining inside the nest 2 can be killed. As shown in FIG. 1 (d), it is preferable to use the insecticidal aerosol product 7 for spraying the bee insecticidal composition.

The insecticidal aerosol product 7 is configured as a pressure-resistant container 8 filled with an insecticidal aerosol agent containing a bee insecticidal composition, an organic solvent, and a propellant. In preparing the insecticidal aerosol, the aerosol stock solution is first prepared by dissolving the bee insecticidal composition in an organic solvent in consideration of workability. Then, this aerosol stock solution is sealed in the pressure-resistant container 8 together with the propellant. As the organic solvent and propellant used in the insecticidal aerosol product 7, the substances listed above for the detection aerosol product 3 can be used in the same manner as in the detection aerosol product 3.

The bee insecticidal composition preferably contains a pyrethroid-based active ingredient. As the pyrethroid-based active ingredient, the same pyrethroid-based active ingredient used in the above-mentioned bee excitement-inducing composition can be used. The pyrethroid-based active ingredient is not limited to use alone, and two or more of them may be contained in a bee insecticidal composition in combination. In particular, in the bee insecticidal composition, it is more preferable to contain at least one of monfluorotrin, d-T80-resmethrin, d-T80-phthalthrin, and d.d-T80-praletrin as an active ingredient. In addition, the bee insecticidal composition may contain other insecticidal components in addition to the pyrethroid insecticidal components listed above. Examples thereof include neonicotinoid insecticidal components such as dinotefuran, organophosphorus insecticidal components such as fenitrothion, and carbamate insecticidal components such as propoxul.

In the method for detecting a beehive according to the present invention, the same composition may be used as the excitement-inducing composition of the bee and the insecticidal composition of the bee, and the insecticidal aerosol product 7 may be used, for example, for detection. Similar to the aerosol product 3, "Hunter Z PRO 510 mL for bees and bugs, which is also effective against bees" manufactured by Dainihon Jochugiku Co., Ltd. can be used.

By spraying the insecticidal aerosol agent containing such a pyrethroid active ingredient from the insecticidal aerosol product 7, it becomes easy to treat the bee insecticidal composition on the nest 2 hidden in the grass. In particular, the injection amount of the insecticidal aerosol agent is preferably set to be larger than the injection amount of the detection aerosol agent as the amount of the pyrethroid-based active ingredient contained. If the amount of the pyrethroid active ingredient in the spray amount of the insecticidal aerosol is sufficiently large, for example, when monfluorotrin is contained as the active ingredient, the bees are knocked down and bite damage is avoided. You can get rid of beehives. When the insecticidal aerosol product 7 is used, the surroundings of the nesting place N can be visually recognized prior to the injection to the bee nesting place N and its surroundings, or after the injection to the bee nesting place N and its surroundings. It is preferable that the insecticidal aerosol agent is directly sprayed from the aerosol product 7 toward the bees (5a, 5b) flying in the region to kill the bees (5a, 5b).

After detecting the beehive in the search space S and exterminating the bees in the nest (step S5 in FIG. 2), or after confirming that the beehive does not exist in the search space S (step S3: No). ), If there is a search space in which the bee excitement-inducing composition has not been sprayed (step S6: Yes), the bee excitement-inducing composition is moved to the next search space (step S7), and the steps S2 to S5 are performed in the search space. repeat. If there is no search space where the bee excitement-inducing composition has not been sprayed (step S6: No), the worker 1 can take off the bee sting protective suit and safely carry out the weeding work.

According to the above procedure, in the method for detecting a beehive according to the present embodiment, when a beehive is present in the search space S, the bees in the nest fly from the nest by spraying the excitement-inducing composition of the bee. Even if the nesting place is in an invisible area, it is possible to observe the flying bees, so that the existence of the beehive can be easily detected and the nesting place can be specified. As a result, it is possible to avoid accidentally stimulating the nest and suffering bite damage without noticing the beehive in the search space.

In this embodiment, an example in which grass serves as a shield has been described, but the shield is not limited to grass, and depending on the work place, an object such as a tree, rock, or rubble may serve as a shield. .. When any object serves as a shield, according to the method for detecting a beehive according to the present invention, the existence of a beehive can be easily detected and the nesting location can be specified.

Next, the method for detecting a beehive according to the present invention will be described in more detail based on specific examples, but the present invention is not limited thereto.

(Aerosol for detecting bees and abs)
Monfluorotrin 0.25 w / v%, isopropyl alcohol (IPA) 30 w / v%, and normal paraffin (neothiolol), which is an organic solvent, were mixed as a residue (balance) to prepare an aerosol stock solution for detection. The undiluted solution of the aerosol for detection and the LPG gas to be the propellant were sealed in a pressure-resistant container at a volume ratio of 1: 1 to obtain an aerosol for detecting bees and abs used in this example.

(Aerosol for bee and ab insecticide)
An aerosol stock solution for insecticide was prepared by mixing monfluorotrin 0.15 w / v%, d-T80-resmethrin 0.10 w / v%, IPA 30 w / v%, and neothiozol as a residue (balance). The stock solution of the insecticidal aerosol and the LPG gas used as the propellant were sealed in a pressure-resistant container at a volume ratio of 1: 1 to obtain an aerosol for bee and abu insecticide used in this example.

In this example, in carrying out the field work, the worker wore a bee sting protective suit and sprayed the bee / ab detection aerosol on the grass before the start of the work. The amount, based on the search space having an area of 100 m ^2, and a bee-Abu perceive aerosol agent 1000mL (12.5mg / ^{m 2} as the amount of Mont fluoro Trindade).

After spraying the bee / ab detection aerosol, if it jumps out of the grass and flies into the surrounding space, the bee / ab insecticidal aerosol is used to exterminate the bees, and the beehives that exist at the bee's flight source are covered with bees. -The nest itself was exterminated by spraying and applying an aerosol for killing bees. The amount used was 500 mL of bee / ab insecticidal aerosol (37.5 mg / m ² as the amount of monfluorotrin and 37.5 mg / m 2 as the amount of d-T80-resmethrin) for one nesting site (about 10 m ^{2) of the bee.} It was set to 25 mg / m ² ).

<Example 1: When a beehive exists>
Bees were observed to fly out of their nests and into the surrounding space by spraying aerosols for detecting bees and abs. At that time, the bees and the beehives could be exterminated by spraying the bee / abu insecticidal aerosol. After that, the workers engaged in outdoor work in the grass.

<Example 2: When there is no beehive>
No bee flight was observed in the vicinity after spraying the bee / ab detection aerosol. In this case, the worker engaged in outdoor work in the grass as it was.

<Result>
By identifying the presence or absence of beehives in the work area and the nesting site, and exterminating the nests in advance, the damage caused by bites could be reduced. In addition, since the work was carried out outdoors with the bee / ab detection aerosol sprayed around the work area, it also helped prevent bees from flying into the vicinity of the work area.

The method for detecting a beehive of the present invention can be used for the purpose of reducing the bite damage of a bee when carrying out outdoor work such as weeding work in grass, bushes, etc., felling work, decontamination work, etc. It is possible.
