Description

  The present invention relates to a method of detecting beehives in a search space including areas not visible due to a shield.

  In field work such as weeding with grass, bushes with mixed trees, and grass unevenness etc. (hereinafter collectively referred to as "grass unevenness"), I accidentally stimulate the nest without noticing that the bees nest in the work place Can suffer from bites. In order to prevent bite damage, it is effective to wear a bee bite protective suit. However, outdoor work with the bee bite protective clothing is not only limited by the bee bite protective clothing, which restricts the operator's visibility and restricts the behavior, but also increases the temperature in the clothing considerably. There are difficulties in continuing the time. Therefore, it is desirable to wear a bee-bite protective suit before the start of the field work to eliminate beehives in a short time, and then take off the bee-bite protective suit and carry out the field work.

  In the past, techniques have been known that use aerosol products to control beehives. For example, Patent Document 1 discloses a method for controlling bees which directly sprays an aerosol agent to bees to control the bees in the nest and prevents the bees that escape the control from returning to the nest. It is disclosed.

  Patent Documents 2 and 3 disclose a method of controlling bees, which comprises applying a composition containing montfluorothrin as an active ingredient to a bee habitat.

JP, 2016-74645, A JP, 2011-144151, A JP, 2015-93846, A

  However, the bee control method disclosed in Patent Document 1 assumes nesting in a structure such as a house, and is premised on the fact that the nesting place can be confirmed in advance. The methods of exterminating bees of Patent Documents 2 and 3 also assume that the habitat of the bees has been confirmed.

  In the field work, the line of sight is blocked by grass, trees, etc., and it may be difficult to even detect the presence or absence of the nesting place rather than confirming the nesting place. For example, large hornets often nest near the ground or in the ground, but in weeding work where a heavily planted grass is used as a working place, it is very difficult to detect the presence of nests because dense grass can not be seen near the ground. Have difficulty. This, coupled with the risk of the hornets, can cause serious damage.

  The present invention has been made in view of the above problems, and in a search space including an area not visible due to a shield, a method of detecting a beehive which can identify the presence or absence of a beehive and a nesting place thereof. Intended to provide.

The characteristic configuration of the beehive detection method according to the present invention for solving the above problems is as follows:
A method of detecting a beehive in a search space including an area not visible by a shield, comprising:
A first step of spraying a bee stimulant composition in the search space;
A second procedure in which, in response to the spouted bee stimulation-inducing composition, a shield located in the vicinity of the bee appearing in the visible region, or a region invisible by the shield is a nest place of the bee ,
To include
The application amount of the bee stimulation-inducing composition is that the bees are excited without knockdown symptoms.

  According to the method for detecting beehives of this configuration, when bees are present in the search space, the bees in the nest become excited without knockdown symptoms due to the application of the bet stimulation-inducing composition and the nest Fly from Even if the nesting place is in an invisible area, it is possible to observe the flying bees, so it is possible to easily detect the presence of a beehive and identify the nesting place. Thereby, it is possible to avoid accidentally stimulating the nest and receiving the sting damage without noticing the beehive in the search space.

In the method of detecting a beehive according to the present invention,
The bee stimulation-inducing composition contains a pyrethroid active ingredient,
In the first step, the bee stimulant composition is sprayed by spraying the sensing aerosol agent from an aerosol in which a sensing aerosol agent containing the stimulant composition and a propellant is enclosed in a pressure container. It is preferable to carry out.

  According to the method for detecting beehives of this configuration, since the beech excitation-inducing composition contains the pyrethroid active ingredient, a good excitation-inducing effect can be obtained. In addition, by using an aerosol, it is possible to easily spread the bee stimulation-inducing composition widely. As a result, the presence or absence of a beehive in the search space can be easily confirmed.

In the method of detecting a beehive according to the present invention,
The pyrethroid active ingredient contains at least montfluorothrin,
It is preferable that the injection amount of the sensing aerosol agent in the first procedure is adjusted to 0.2 to 50 mg / m ² as the amount of the montfluorothrin.

If the injection amount of the sensing aerosol agent is 0.2 to 50 mg / m ² as the amount of monfluorothrin, the number of bees exhibiting knockdown symptoms in the nest is suppressed. Therefore, a sufficient number of bees fly from the hive, and there is no need to detect the presence of the bee hive. As a result, most of the bees in the nest show knockdown symptoms and fail to detect the presence of the beehives, and bite damage caused by some bees that did not exhibit knockdown symptoms when approaching the nest accidentally. Can avoid receiving

In the method of detecting a beehive according to the present invention,
It is preferable to further include a third procedure of spraying an insecticidal composition of bees around the place where the bee nest place in the second procedure.

  According to the method of detecting beehives of this configuration, if there are bees in the search space, even if the nesting place is in an invisible area, the bees are present before the execution of the third procedure. The third procedure can be performed in a short time, and the bees in the nest can be easily eliminated.

In the method of detecting a beehive according to the present invention,
The insecticidal composition for bees comprises a pyrethroid active ingredient,
The spraying of the bee insecticidal composition in the third procedure is carried out by spraying the insecticidal aerosol agent from an aerosol in which the insecticidal aerosol agent containing the insecticidal composition and a propellant is enclosed in a pressure container. Is preferred.

  According to the method for detecting beehives of this configuration, since the insecticidal composition of bees contains a pyrethroid active ingredient, it is possible to obtain a good insecticidal effect. In addition, an insecticidal composition of bees can be rapidly sprayed around the area where the bees nest. As a result, the bees in the nest can be easily eliminated.

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

  According to the method for detecting bees in this configuration, when spraying the sensing aerosol, the number of bees exhibiting knockdown symptoms is suppressed to fly a sufficient number of bees from the nest, and when spraying the insecticide for spraying insecticides The bees in the nest can be eliminated while knocking down the bees in the nest and the bees in the nest to avoid bite damage.

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

  According to the method for detecting beehives of this configuration, since the above-mentioned appropriate ones are used as the pyrethroid-based active ingredients, it is possible to obtain a good excitation inducing effect and an insecticidal effect.

In the method of detecting a beehive according to the present invention,
It is preferred to use the same composition as the bee excitement composition and the bee insecticidal composition.

  According to the method for detecting beehives of the present configuration, the work from detection of bees to elimination using a single type of composition only by changing the spraying method, the amount of spraying, etc. according to the application. Can be implemented. Therefore, it is not necessary to determine the amount to be delivered to the work site in consideration of the respective usage amounts of the bee stimulation-inducing composition and the bee insecticidal composition, and to avoid a situation where only one composition is lacking at the work site be able to.

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

  According to the method of detecting a beehive of the present configuration, the nesting place of the bee can be accurately identified from the flight path of the flying bee. This makes it possible to avoid misidentifying nesting places and accidentally stimulating the nest to suffer bite damage.

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

  Hereinafter, an embodiment relating to the beehive detection method of the present invention will be described based on FIG. 1 and FIG. However, the present invention is not intended to be limited to the configurations described in the embodiments and drawings described below.

  A method of detecting a beehive according to the present embodiment is a search space (e.g., grass, bushes with mixed trees, uneven grass, etc.) including an area which can not be visually recognized by a shield (e.g., grass, trees, etc.). It is used to detect the existence of and identify the nesting place. When performing field work such as weeding work, if you detect the presence or absence of bees in the search space in advance and identify the nesting place, you will accidentally stimulate the nest and notice bites without noticing the bees. It can avoid being damaged. When the presence of a bee hive is detected, it is possible to reduce the bite damage by refraining from accessing the nesting place or preferably eliminating the bees in the nest which has been detected.

  The bees to be detected in the nest include the leaf wasps such as the phyllophony wasp, segrea wasp, and the beech bee; And bees.

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

  FIG. 1A shows how the worker 1 carries out the weeding work in the work space S. In the work space S, there are uneven grasses in which tall tall grasses are densely present, and in the area H shaded by an alternate long and short dash line corresponding to the plant height, the grass becomes a shield and the line of sight is blocked. It is an area which can not be visually recognized (hereinafter, "shielded area"). For example, in the shielded area H, even if the nest 2 of the hornets was near the ground, the worker 1 can not visually recognize the presence. In this state, the worker 1 may approach the nest 2 without noticing the nest 2 and may suffer bite damage.

  Therefore, in the method for detecting a beehive according to the present embodiment, before performing the weeding operation, the working space S is used as a search space for the bee nest, and the presence of the bee nest is detected according to the procedure shown in FIG. , Eliminate the bees in the beehives that you have detected. In carrying out the method of detecting a beehive according to the present embodiment, first, the worker wears a bee bite protective suit (step S1). After that, the beech excitation-inducing composition is sprayed onto the grass in the search space S (step S2). As shown in FIG. 1 (b), it is preferable to use the aerosol product 3 for sensing, for the application of the beech stimulation-inducing composition.

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

  The beech stimulation-inducing composition preferably contains a pyrethroid-based active ingredient. Examples of pyrethroid-based active ingredients include montfluorothrin, d-T80-resmethrin, d-T80-phthalthrin, d · d-T80-praretrin, cyfluthrin, phenothrin, cypenothrin, permethrin, tralomethrin, bifenthrin, deltamethrin, silafluofen, etho Examples include fenprox, imiprothrin, cypermethrin, empenthrin, transfluthrin, metfluthrin, profluthrin, telarethrin, arethrin, prarethrin, pyrethrin, imiprothrin and the like. In particular, in a beech stimulation-inducing composition, at least montfluorothrin is contained as one of active ingredients among montfluorothrin, d-T80-phthalsulin, and d · d-T80-praretrin, singly or in combination of two or more. It is more preferable to use in combination. Moreover, when an optical isomer and a geometric isomer exist in the molecular structure of a pyrethroid insecticidal component, they are also included in the present invention.

  The aerosol stock solution contains an organic solvent capable of dissolving the bee's excitable composition. The aerosol stock solution is prepared by dissolving the bee's excitement-inducing composition in the organic solvent. Since the properties of the organic solvent affect the formation of spray particles when the sensing aerosol 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 for preparation of aerosol stock solutions include hydrocarbon solvents such as normal paraffin and isoparaffin, alcohols such as ethanol, isopropanol, 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, and ester solvents. The organic solvents listed above are not limited to single use, and two or more kinds may be used in combination.

  The aerosol stock solution can also be formulated into an aqueous aerosol by compounding water, in which case a surfactant is added as needed. Examples of surfactants include ethers such as polyoxyethylene alkyl ethers, polyoxyethylene alkyl phenyl ethers, polyoxyethylene polyoxypropylene alkyl ethers, polyoxyethylene alkyl amino ethers, polyethylene glycol fatty acid esters, Non-ionic surfactants such as polyoxyethylene sorbitan fatty acid esters, fatty acid esters such as polyoxyethylene glycerin fatty acid esters, polyoxyethylene styrenated phenol, polyalkalamide of fatty acid, polyoxyethylene (POE) styryl Anionic surfactants such as phenyl ether sulfate, polyoxyethylene (POE) alkyl ether sulfate, and dodecylbenzene sulfate can be mentioned.

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

  The propellant is adjusted so that the volume ratio (a / b) of the aerosol stock solution (a) to the propellant (b) is 40/60 to 80/20. If the above volume ratio (a / b) is smaller than 40/60, the propellant becomes excessive, so the relative enclosed amount of the aerosol undiluted solution in the pressure container decreases, and the bees are detected with one sensing aerosol product 3 The area over which the excitation inducing composition can be dispersed is narrowed, which may lower the working efficiency. If the above volume ratio (a / b) is greater than 80/20, the propellant will run short, and the injection will shorten the distance over which the excitement-stimulating composition of the bee can reach, and will not notice until worker 1 approaches nest 2 There is a fear. In addition, when the volume ratio (a / b) is adjusted to the said suitable range, the internal pressure of the aerosol agent in a pressure-resistant container will be 0.25-0.70 MPa (25 degreeC).

  As the aerosol product 3 for sensing, for example, "Han-Ab Hunter Z PRO 510 mL which works against hornets", which is manufactured by Dainippon Kikai Co., Ltd., can be used.

  By spraying the sensing aerosol agent using the sensing aerosol product 3, even a nonvolatile substance such as montfluorothrin can be rapidly and widely dispersed. Among the pyrethroid active ingredients, montfluorothrin is highly effective in stopping the flight to bees, and aerosol products containing montfluorothrin as an active ingredient in an aerosol agent are generally treated by direct spraying on bees. Are often assumed products. However, the spray amount of the aerosol agent for sensing should be adjusted and sprayed widely to the grass so that the spray amount of the bech stimulation-inducing composition becomes an amount that the bee does not exhibit knockdown symptoms and becomes an excited state. It is possible to avoid killing the bees in the nest. By being injected in such an amount, the bees (5a, 5b) come out of the nest 2 as shown in FIG. There is an action that jumps into the area where it can be and flies. This confirms the presence of beehives.

The “amount that the bee does not exhibit knockdown symptoms and becomes an excited state” varies depending on the active ingredient, but, for example, when the active ingredient contained in the bet stimulation-inducing composition is montfluorothrin, the sensing aerosol 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 The ingredients can be sprayed. Specifically, in order to achieve a suitable injection amount, when using “Dane Nippon Hyuga-Kiku Co., Ltd.“ Hunt and Abu Hunter Z PRO 510 mL that works against hornets ”for spraying of beech stimulation-inducing agents, It is preferred to use the aerosol product in a ratio of two to a search space having an area of about 100 m ² .

  In the method for detecting the beehive according to the present embodiment, as shown in FIG. 1 (c), when the bee (5a, 5b) flies out of the nest 2 as seen in FIG. The appearance of bees (5a, 5b) in the area where it can be confirmed is confirmed (Step S3 in FIG. 2: Yes). Thus, when the appearance of bees (5a, 5b) in the visible region is confirmed, the grass (6a, 6b) located near the observed bees (5a, 5b), or the grass (6a, 5b) An area which can not be visually recognized by 6b) (an area surrounded by a thick line in this figure) is set as a nest place N of bees (step S4 in FIG. 2). The appearance of the bees in the visible area may be observed by the worker responsible for the spreading of the bee stimulation-induced composition, or another worker may be responsible for the observation. An optical device such as a camera or binoculars may be used to observe the appearance of bees in a visible area. In particular, when a worker different from the worker in charge of spraying the bee stimulation-inducing composition is in charge of observation, the worker in charge of observation observes using the optical instrument from outside the search area S. You can avoid getting bite damage. In addition, the appearance of the bees in the visible area is not limited to the confirmation of the bees by visual observation, and may be confirmed by an image recorded using a video camera, a still camera or the like. In order to more accurately define the nesting place of bees, it is preferable to identify the grass (6a, 6b) located at the flight source by observing the flight path of the bee (broken line in FIG. 1 (c)). . The confirmation by the image recorded using a video camera, a still camera, etc. is applicable also to confirmation of such a flight path.

  Thus, even if it is unknown whether or not there is a beehive in the search area S, it invades while searching the search area S while scattering the beech excitation-inducing composition, and observing the bee's flight Can detect the existence of the nest. In addition, when the bees do not appear in the visible region even after the bee excitation-inducing composition is sprayed in step S2 of FIG. 2 (step S3: No), the bees are searched in the search space S in which the bee excitation-inducing composition is dispersed. It can be confirmed that there is no nest.

  In the beehive recognition method according to the present embodiment, it is preferable to spray the bee insecticidal composition to the bee nest location N after detecting the beehive (step S5 in FIG. 2). As a result, it is possible to kill the bees 5c remaining inside the nest 2 without flying away after the application of the bee stimulation-inducing composition. At this time, the insecticidal composition may be applied not only to the nesting place N of bees but also to the periphery thereof. As a result, even if there is an actual bee nest at a position slightly offset from the place where the bee nest site N, the bee 5 c remaining inside the nest 2 can be killed. As shown in FIG. 1 (d), it is preferable to use an aerosol product 7 for insecticides for spraying the insecticidal composition of bees.

  The insecticidal aerosol product 7 is configured as a pressure container 8 in which an insecticidal aerosol agent containing an insecticidal composition of bees, an organic solvent, and a propellant is enclosed. In preparation of the aerosol for insecticidal, in consideration of workability, an insecticidal composition of bees is first dissolved in an organic solvent to prepare an aerosol stock solution. Then, the aerosol stock solution is sealed in the pressure container 8 together with the propellant. As the organic solvent used for the insecticide aerosol product 7 and the propellant, the materials listed above for the detection aerosol product 3 can be used in the same manner as the detection aerosol product 3.

  The bee insecticidal composition preferably contains a pyrethroid active ingredient. As the pyrethroid-based active ingredient, the same pyrethroid-based active ingredient used in the above-described bee stimulation-inducing composition can be used. The pyrethroid-based active ingredient is not limited to use alone, and two or more kinds may be combined and contained in the insecticidal composition of bees. In particular, in an insecticidal composition of bees, it is more preferable to contain at least one of montfluorothrin, d-T80-resmethrin, d-T80-phthalthrin, and d.d-T80-praretrin as an active ingredient. In addition to the pyrethroid insecticidal component listed above, other insecticidal components can be added to the bee insecticidal composition. Examples thereof include neonicotinoid insecticidal components such as dinotefuran, organophosphorus insecticidal components such as fenitrothion, and carbamate insecticidal components such as propoxur.

  In the method for detecting beehives according to the present invention, the same composition may be used as a bech stimulation-inducing composition and a bee insecticidal composition, and the insecticidal aerosol product 7 may be used, for example, for detection. As in the case of the aerosol product 3, "Han-Abu Hunter Z PRO 510 mL, which is effective for hornets" manufactured by Dainippon Kikai Gakuen Co., Ltd. can be used.

  By spraying an insecticidal aerosol agent containing such a pyrethroid active ingredient from the insecticidal aerosol product 7, it becomes easy to treat the insecticidal composition of bees to the nest 2 hidden in the grass. In particular, the injection amount of the insecticide aerosol is preferably set larger than the injection amount of the sensing aerosol as the amount of the pyrethroid-based active ingredient contained. If the amount of pyrethroid-based active ingredient in the spray amount of the insecticide aerosol is sufficiently large, for example, when montfluorothrin is contained as an active ingredient, bees are not knocked down to avoid being stricken while being attacked. You can control the beehives. In addition, when the aerosol product 7 for insecticidal use is used, visible around the nesting place N is possible prior to injection to the nesting place N of the bee and its periphery or after injection to the nesting place N of the bee and its periphery Preferably, the insecticidal aerosol agent is directly jetted from the aerosol product 7 toward the bees (5a, 5b) flying in the area to kill the bees (5a, 5b).

  After detecting bees in the search space S and eliminating bees in the nest (Step S5 in FIG. 2) or after confirming that there are no bees in the search space S (Step S3: No) Furthermore, if there is a search space for which the bee excitement-inducing composition has not been sprayed (step S6: Yes), move to the next search space (step S7) and perform steps S2 to S5 in the search space. repeat. If there is no search space where the bee's excitation inducing composition has not been dispersed (Step S6: No), Worker 1 can take off the bee sting protective clothing and carry out the weeding work safely.

  According to the above-described procedure, in the method of detecting a beehive according to the present embodiment, when a beehive is present in the search space S, the bee in the nest flies from the nest by the application of the bet stimulation composition. Even if the nesting place is in an invisible area, it is possible to observe the flying bees, so it is possible to easily detect the presence of a beehive and identify the nesting place. Thereby, it is possible to avoid accidentally stimulating the nest and receiving the sting damage without noticing the beehive in the search space.

  In the present embodiment, an example in which grass is a shield is described, but the shield is not limited to grass, and it may be considered that an object such as a tree, a rock, a rubble may be a shield depending on the work place. . When any object is a shielding object, according to the method for detecting a beehive according to the present invention, it is possible to easily detect the existence of a beehive and to specify the nesting place.

  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.

(Acetomic detection aerosols)
Montflurothrin 0.25 w / v%, isopropyl alcohol (IPA) 30 w / v%, and normal paraffin (neothiozole) which is an organic solvent as a balance (balance) were mixed to prepare an aerosol stock solution for detection. An aerosol stock solution for sensing and LPG gas as a propellant were enclosed in a pressure container at a ratio of 1: 1 in volume ratio, and used as an aerosol for bee / ab detection used in this example.

(Aeros for Bee and Insecticide)
Montrofluthrin 0.15 w / v%, d-T80-resmethrin 0.10 w / v%, IPA 30 w / v%, and neothiozole as a balance (balance) were mixed to prepare an aerosol stock solution for insecticidal use. The aerosol stock solution for insecticidal use and LPG gas as a propellant were enclosed in a pressure container at a volume ratio of 1: 1, and used as an aerosol for bee-abicides used in this example.

In the present example, when carrying out the field work, the worker wears the bee bite protective suit before the start of the work and sprays the bee-abs detection aerosol onto the grass. 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 and abu detection aerosol, if it flies out from the grass into the surrounding space, the bee is eliminated using the bee and abu insecticide aerosol, and the bee is removed from the bee's hive. -The nest itself was eliminated by spray application of an insecticidal aerosol. The amount used is 500 mL of a bee-ab insecticidal aerosol (37.5 mg / m ² as the amount of montfluorothrin) and the amount of d-T80-resmethrin for one bee nest place (about 10 m ² ) It was 25 mg / m ² ).

<Example 1: When a beehive exists>
By spraying the bee-and-abu detection aerosol, the bees came out of the hive and jumped into the surrounding space. At that time, the bees and beehives were able to be eliminated by spraying a bee-abicidal aerosol. After that, the workers engaged in outdoor work in the grass.

<Example 2: When no beehive exists>
After spraying the Hachi-Abu detection aerosol, the bees did not fly around. In this case, the worker engaged in the field work in the grass as it was.

<Result>
By identifying the presence or absence of the beehive in the work place and the nesting place and eliminating the nest in advance, the bite damage could be reduced. In addition, because it was an outdoor work in the state where the bee / abu detection aerosol was sprayed around the work place, it also led to prevention of the bees in the vicinity from coming into the vicinity of the work place.

  The method for detecting beehives of the present invention can be used to reduce stinging damage to bees when carrying out field work such as weeding work with grasses and bushes, harvesting work, decontamination work, etc. It is possible.
