Description

The present invention relates to a pest control device and a pest control method. More specifically, the present invention relates to a pest control device and a pest control method capable of easily exterminating pests with a simple operation.

Honeybees (mainly Western honeybees) have become important players in pollen mating work for cultivating fruits and vegetables such as strawberries and melons, but their populations have been declining in recent years. For this reason, the price of honeybees supplied by beekeepers has also risen, and it has become a problem that producers cannot secure sufficient honeybees to carry pollen.

There are various theories as to why honeybees are decreasing, but the view that pests are the cause is predominant. Bees parasitized by pests during the pupal period show symptoms such as dwarfing of adults, shrinking wings and inability to fly, or death during development.

Therefore, as shown in Patent Document 1, "a parasite control composition and a control method in a honeybee population" using phenpyroximate has been proposed. In the present invention, when a honeybee comes into contact with a carrier containing phenpyroximate, which is a compound known to be useful as an acaricide, as an active ingredient, the active ingredient adheres to the honeybee worm body, and further within the honeybee population. The active ingredient is diffused to other honeybees by the activity in the honeybee population, and it is possible to control the parasites of the entire honeybee population.

However, in the above invention, when a carrier carrying or coated with an active ingredient is installed in a nest box, all the nest boxes must be opened and the carrier containing the active ingredient must be installed, which is troublesome. rice field.

The present invention has been devised in view of the above points, and an object of the present invention is to provide a pest control device and a pest control method capable of easily exterminating pests with a simple operation.

In order to solve the above problems, the pest control device of the present invention is detachably attached to a housing in which the first opening and the second opening are formed, and the first opening. An intake portion that forcibly takes in outside air into the housing through the portion and a retention portion that is provided in the housing in communication with the first opening and temporarily retains the outside air taken in by the intake portion. A pest control component generating section, which is provided in the housing in communication with the staying section and the second opening, is provided to generate a pest control component.

Here, the housing in which the first opening and the second opening are formed, the retention portion provided in the housing in communication with the first opening, the retention portion in the housing, and the second. The pest control component generating unit provided in communication with the opening can prevent the generated pest control component from easily leaking out of the housing from other than the first opening and the second opening. Further, even when the pest control component is harmful to humans, it is possible to prevent the human (worker) from inhaling the pest control component, and the pest control component can be handled safely.

Further, a housing in which the first opening is formed, a retention portion provided in the housing in communication with the first opening, and a pest control component generation provided in communication with the retention portion in the housing. Depending on the unit, the pest control component generated in the pest control component generation unit gradually diffuses in the housing, and a part of the pest control component flows out of the housing through the first opening through the retention portion. As a result, it is possible to visually confirm from the outside of the housing that the pest control component has been generated inside the housing. Therefore, it is possible to save the trouble of opening the housing and checking whether or not the pest control component is generated.

Further, an intake unit that forcibly takes in outside air into the housing through the first opening and an intake portion that communicates with the first opening in the housing are provided to temporarily retain the outside air taken in by the intake unit. It is possible to prevent the raw material of the pest control component from being directly blown to the raw material of the pest control component by the vigorous outside air taken in by the intake part, soaring in the housing and being discharged from the discharging part. Therefore, the flow of the outside air can be slowed down in the housing without finely setting the strength of taking in the outside air, so that the operation is easy.

Further, as described above, when the pest control component flows out from the first opening by the intake unit detachably attached to the housing, the pest control component is sucked by removing the intake part from the housing in advance. It can be prevented from hanging on the part. This is because if a pest control component is applied to the intake portion, the intake portion may deteriorate.

Further, a housing in which the first opening and the second opening are formed, an intake portion for forcibly taking in outside air into the housing through the first opening, and a first opening in the housing. The outside air taken in by the pest control component generation section, which is provided in communication with the retention section and the retention section and the second opening and generates the pest control component, is taken in by the first opening. Since it goes to the second opening through the retention part and the pest control component generation part, the pest control component generated by the pest control component generation part is used as a mixed gas together with the outside air outside the housing by utilizing the flow of the outside air. Can be discharged to. Therefore, no operation is required to discharge the mixed gas, so that the operation can be easily performed.

Further, when the pest control device discharges the mixed gas of the pest control component and the outside air generated by the pest control component generation unit to the outside of the housing through the second opening by forcibly taking in the outside air by the intake unit. The mixed gas is discharged from the discharge port to the outside of the housing by utilizing the flow of the outside air taken in from the intake unit.

Further, when the pest control component generation unit has a precursor of the pest control component arranged inside, the pest control component can be generated from the precursor of the pest control component inside the pest control component generation unit. ..

Further, when the pest control component generation unit is detachably mounted in the housing, it can be easily replaced when the pest control component generation unit deteriorates due to corrosion or the like.

Further, when a heating unit for heating the pest control component generation unit in which the precursor of the pest control component is arranged is provided, the heat energy given by the heating unit is used to generate the pest control component from the precursor. It becomes possible. And since it is possible to save the trouble of adjusting the heating temperature, the operation is easy.

Further, when the housing is provided with a shielding plate substantially orthogonal to the flow of the outside air flowing in from the retaining portion, a part of the flow of the outside air flowing in from the retaining portion is blocked by the windshield, so that the retaining portion Therefore, only a part of the outside air whose flow is slowed down by temporarily retaining the outside air can flow into the pest control component generation unit. As a result, it is possible to prevent the raw material of the pest control component from flying up in the housing and being discharged from the discharge port due to the inflow of a large amount of outside air.

Further, when the pest control component is formic acid, the pests are less likely to have resistance, so that it can be used for a long period of time.

Further, in order to solve the above problems, the pest extermination method of the present invention comprises an arrangement step of arranging a precursor of the pest extermination component in a pest extermination component generation unit provided in a housing, and an arrangement step of arranging the precursor in the arrangement step. The pest extermination component generation unit in the housing, which is substantially closed in the closing step, and the pest extermination component generation unit, which is substantially closed in the closing step, are heated. The pest control component generation step of generating the pest control component from the precursor and the pest control component generated in the pest control component generation step are prevented from flowing out from the first opening provided in the housing. A confirmation step to confirm, and after confirming that the pest extermination component flows out from the first opening in the confirmation step, an intake unit that sucks outside air into the housing through the first opening While sending the outside air toward the first opening, the intake portion is attached to the first opening to start the intake, so that the outside air taken in by the intake portion is temporarily introduced in the housing. And the discharge step of discharging the mixed gas of the outside air and the pest control component generated in the pest control component generation step to the outside of the housing through the second opening provided in the housing. A spraying step of spraying the mixed gas discharged in the discharging step toward pests is provided.

Here, a mounting step of arranging the precursor of the pest control component in the pest control component generation section provided in the housing, and a housing in which the pest control component generation section in which the precursor is arranged in the placement step is placed inside. By the closing step of substantially closing the body, it is possible to prevent the generated pest control component from easily leaking to the outside of the housing.

In addition, the heat energy given by the heating part is utilized by the pest control component generation step of heating the pest control component generation part in the housing substantially closed in the closing step to generate the pest control component from the precursor. It is possible to generate pest control components from the precursors. Therefore, it is possible to save the trouble of adjusting the heating temperature, and the operation is simple.

In addition, the pest control component is generated in the pest control component generation unit by the confirmation step of confirming that the pest control component generated in the pest control component generation step flows out from the first opening provided in the housing. You can confirm that from outside the housing.

Further, in the confirmation step, after confirming that the pest extermination component flows out from the first opening, the outside air is taken into the housing through the first opening by the intake portion toward the first opening. By attaching the intake unit to the first opening and starting the intake air, the outside air taken in by the intake unit is temporarily retained in the housing and generated in the outside air and pest control component generation process. Not only can the outside air be taken into the housing by the discharge process of discharging the mixed gas with the pest control component to the outside of the housing through the second opening provided in the housing, but also the first opening. Since the intake part can be attached to the first opening to start the intake while pushing the pest control component flowing out from the inside of the housing, the deterioration of the intake part is suppressed by the pest control component being applied to the intake part. can.

Further, due to the discharge process, the outside air taken into the housing is temporarily retained in the housing, so that the flow of the outside air becomes gentle. As a result, the vigorous outside air taken in from the intake unit is directly blown to the precursor of the pest control component arranged in the pest control component generation unit, and the precursor flies up in the housing to open the second opening. It is possible to prevent the discharge from the unit. In addition, it is easy to operate because it is possible to save the trouble of adjusting the strength of the flow of outside air in the housing.

Further, in the discharge step, the mixed gas of the outside air and the pest control component is discharged from the second opening to the outside of the housing by utilizing the flow of the outside air taken in from the first opening.

In addition, by the spraying process of spraying the mixed gas discharged in the discharge process toward the pests, the mixed gas containing the pest control component discharged by utilizing the flow of the outside air taken in by the intake unit is sprayed on the pests. Therefore, pests can be easily exterminated.

The pest control device and the pest control method according to the present invention are a pest control device and a pest control method that can easily remove pests with a simple operation.

It is a perspective view of the mite extermination apparatus A which concerns on embodiment of this invention. It is an exploded perspective view of the mite extermination apparatus A which concerns on embodiment of this invention. It is explanatory drawing of the mite extermination apparatus A which concerns on embodiment of this invention. It is a usage state explanatory view which showed the state which sprayed the mixed gas to the nest C box using the mite extermination apparatus A. It is a flowchart of the mite extermination method which concerns on embodiment of this invention.

Hereinafter, the mite extermination device A of the present invention will be described with reference to FIGS. 1 to 5, and will be used for understanding the present invention.

First, the embodiment of the mite extermination device A of this embodiment will be described with reference to FIGS. 1 and 2.
The mite extermination device A has a stainless steel housing A1, a mounting table A2 on which the housing A1 is mounted, and a handle A3 attached to the mounting table A2. Further, the housing A1 is composed of a lid portion A10 and a container body A11, and the lid portion A10 is fixed to the container body A11 by the fixing means A12, and the housing A1 can be substantially closed by closing the lid portion A10. Further, in the container body A11, a shielding plate A13 that divides the container body A11 into two adjacent spaces is provided.

The housing A1 is an example of a first opening, which will be described later, and is an example of an intake port A11e provided in the container body A11 and a second opening, and is an discharge port provided in the lid body A10. Since the four discharge small holes A11h are opened in the lower part of the side surface A11g of the container body A11 on the side of the container body A11 where the discharge port A10c is provided, the A10c and the container body A11 are not completely closed, but are omitted. It is blocked.

Further, to the outside of the housing A1, an intake air 2 that sends outside air into the housing A1 and formic acid F, which is an example of a pest control component generated in the housing A1, are taken in from the intake air 2. A hose 3 for discharging the mixed gas MG together with the OA to the outside of the housing A1, a heating unit 4 for heating the formic acid generator 10 described later, and a battery 5 for operating the inhaler 2 are provided.

Further, the container body A11 is formed in a hollow structure in which the upper part is open when placed on the mounting table A2, and the formic acid generating unit 1 that produces formic acid F, which is an example of the pest control component, is inside. Is provided. The upper end edge A11a of the container body A11 is provided with a support portion A11b extending substantially horizontally from the upper end edge A11a toward the inside of the container body A11 over the entire circumference, and is directed from the shielding plate A13 toward the side surface A11g side. An auxiliary support portion A11i is provided on the same surface as the support portion A11b.

Further, the formic acid generating unit 1 is between the shielding plate A13 and the side surface A11g, and is provided near the upper end portion A11a and is provided with a formic acid generator 10 capable of generating formic acid F, and intake of the shielding plate A13 and the container body A11. It is provided between the side surfaces A11d on the side of the vessel 2 and includes a retention chamber 11 for temporarily retaining the outside air from the intake vessel 2. The retention chamber 11 is a space between the shielding plate A13 and the side surface A11d. The shielding plate A13 is arranged substantially parallel to the side surface A11d and the side surface A11g in the substantially center of the container body A11 in a plan view, but the present invention is not limited to this. It can be provided close to either one of A11g, whereby the strength of the flow of the outside air OA flowing into the housing A1 can be changed.

The formic acid generator 10 is provided with a supported portion 10b extending substantially horizontally toward the outside at the edge portions 10a of the four sides on the open side, and the supported portion 10b is a supporting portion of the container body A11. It is stacked on A11b and the auxiliary support A11i, whereby the formic acid generator 10 is detachably engaged in the container body A11.

Further, at this time, since the depth inside the formic acid generator 10 is about half the depth of the container body A11, there is a drawing between the bottom plate 10c of the formic acid generator 10 and the bottom plate A11c of the container body A11. As shown in 3, the combustion chamber 10d is formed. The depth inside the formic acid generator 10 is not limited to half the depth of the container body A11, but is about half when the height of the flame 42 ejected from the nozzle 41 of the heating unit 4 is taken into consideration. It is desirable to do.

On the other hand, the outside air taken in by the inhaler 2 has a predetermined flow strength, and when such outside air is sent directly to the formic acid generator 10, oxalic acid OX, which is a precursor of formic acid F, is released. It will be discharged to the outside of the housing. Therefore, the formic acid is generated in the formic acid generator 11 so that the outside air OA taken in from the inhaler 2 can be temporarily retained in the residence chamber 11 and the flow is slowed down so that the outside air OA can flow into the formic acid generator 10. It is provided closer to the intake device 2 than the device 10.

This makes it difficult for oxalic acid OX, which is a precursor of formic acid F, to be discharged to the outside of the housing A1, and the amount of formic acid F produced from oxalic acid OX does not decrease, so that pests can be efficiently exterminated. can. Further, since it is not necessary to adjust the strength of taking in the outside air OA, the trouble of adjusting is saved and the operation can be performed easily. Since oxalic acid OX is a dangerous substance for the human body, sufficient care must be taken when handling it.

Further, above the support portion A11b of the shielding plate A13 with reference to the support portion A11b, there is a shielding portion A13a that blocks a part of the flow of outside air OA from the retention chamber 11 to the formic acid generator 10. A part of the flow of the outside air OA flowing into the formic acid generator 10 is blocked by the shielding portion A13a, and only the remaining outside air OA flows into the formic acid generator 10. At this time, since the outside air OA passes over the shielding portion A13a and flows into the formic acid generator 10, the momentum of the flow of the outside air OA is suppressed and the flow becomes gentle. This makes it more difficult for the oxalic acid OX in the formic acid generator 10 to be discharged to the outside of the housing A1.

Further, the shielding portion A13a has a height of about 4 cm upward with respect to the supported portion 10b, but this height is not limited to 4 cm. It suffices if a part of the outside air OA from the retention chamber 11 can be blocked, and it can be set as appropriate.

Further, the lid portion A10 has a hollow structure having an opening at the lower side, is placed on the upper portion of the container body A11, and covers and closes the opening portion of the container body A11. An elastic material (not shown) such as a rubber material is attached to the edge portion A10a of the lid portion A10 on the side in contact with the container body A11.

As a result, when the formal acid generator 10 is housed in the container body A11 and the lid portion A10 is overlapped with the container body A11 while being pressed by the fixing means A12, the formal acid generator 10 is overlapped on the support portion A11b. Since the supported portion 10b is sandwiched between both the edge portion A10a of the lid portion A10 and the support portion A11b of the container body A11, the formic acid generator 10 is firmly fixed in the housing A1. Further, this can prevent the formic acid generated in the formic acid generator 10 from leaking to the combustion chamber 10d.

Further, it is considered that the formic acid generator 10 may be deteriorated by repeated use, and the formic acid generator 10 needs to be replaced after a certain period of use. Regarding this point, as described above, in the formic acid generator 10, the supported portion 10b, the supporting portion A11b, and the auxiliary supporting portion A11i are overlapped and mounted in a suspended state in the container body A11. It can be easily removed from the body A1.

Further, on the side surface A10b of the lid portion A10 on the side opposite to the side where the intake air 2 is provided, the discharge port A10c that discharges the mixed gas MG of the formic acid F and the outside air OA generated in the formic acid generator 1 to the outside. Is provided. As a result, the formic acid F generated by the formic acid generation unit 1 is discharged to the outside from the discharge port A10c through the hose 3.

Further, the intake air 2 has a curved pipe-like shape, and has an intake port 20 for taking in the outside air OA and a connecting port 21 provided on the opposite side of the intake port 20. A connecting pipe A11f is provided on the side surface A11d of the container body A11 on the intake side 2 side so as to project outward, and a connecting port 21 of the intake device 2 is attached to the tip of the connecting pipe A11f. The outside air OA taken in by the intake port 20 passes through the inside of the intake device 2, further passes through the connecting pipe A11f from the connecting port 21, and is taken into the housing A1 from the intake port A11e.

Then, as shown in FIG. 3, the outside air OA that has flowed into the housing A1 from the intake port A11e temporarily stays in the retention chamber 11 and then moves in the lid portion A10 to get over the shielding portion A13a. It flows into the formic acid generator 10 side. At this time, together with the gaseous formic acid F generated in the formic acid generator 10, it is discharged to the outside from the discharge port A10c through the hose 3.

The position where the intake port A11e is provided is not limited to the container body A11, and may be provided in the lid portion A10. However, in order to sufficiently moderate the momentum of the flow of outside air OA in the retention chamber 11, it is desirable to provide the container body A11.

Further, the position where the discharge port A10c is provided is not limited to the lid portion A10, and may be provided in the container body A11. However, in order to make it difficult to discharge oxalic acid and to facilitate the discharge of only vaporized formic acid, it is desirable to provide it on the lid 10A arranged above.

Further, the intake port A11e and the discharge port A10c may be provided on the same side of the housing A1 (for example, both are on the intake device 2 side). However, in order to efficiently discharge the mixed gas MG, it is desirable to provide it on both sides of the mixed gas MG via the formic acid generator 10.

The battery 5 is a rechargeable battery for operating the inhaler 2, and can be used repeatedly by removing it from the mounting table A2 and charging it after the work. As a result, since the work is performed outdoors in the past, an in-vehicle battery was used as a power source, but it is not necessary to secure a power source and the operation can be performed easily. The power source for operating the inhaler 2 is not limited to the rechargeable battery, and for example, a battery type may be used.

Further, a hose 3 for discharging the formic acid F generated in the formic acid generator 10 to the outside is provided on the side of the housing A1 opposite to the side where the inhaler 2 is provided, and the base end of the hose 3 is a lid. It is attached to the connecting pipe A10d protruding outward from the side surface A10b of the portion A10. The mixed gas MG of formic acid F and outside air OA generated by the formic acid generator 10 is discharged to the outside of the housing A1 from the discharge port A10c provided on the side surface A10b through the connecting pipe A10d.

Further, a nozzle head (not shown) capable of spraying a mixed gas MG of formic acid F and outside air OA onto an object to be sprayed is provided at the tip of the hose 3. As a result, for example, as shown in FIG. 4, the tip of the hose 3 was inserted into the nest gate C1 of the bee hive C infested with mites, and the mixed gas was sprayed into the hive C to parasitize the wasp B. The tick M can be exterminated.

Further, the mounting table A2 is provided with a mounting surface A20 on which the housing A1 can be mounted, and leg members A21 and A21 for supporting the mounting surface A20. Further, a heating unit 4 is provided on the back surface A22 of the mounting table A2, and the heating unit 4 is fixed to the back surface A22 by a fixing member (not shown), and has a gas cylinder 40 filled with flammable gas and flammable gas. A nozzle 41 for ejecting a sex gas is provided. The nozzle 41 is inserted into the container body A11 through the heating holes A11j provided in the bottom plate A11c of the container body A11. As a result, the tip of the nozzle 41 is located in the combustion chamber 10d.

When the gas cylinder 40 is ignited, as shown in FIG. 3, a flame 42 is generated in the combustion chamber 10d, the bottom plate 10c of the formic acid generator 10 is heated, the oxalic acid OX arranged in the bottom plate 10c is heated, and the formic acid F is heated. Is generated. The precursor of formic acid is not limited to oxalic acid, and other substances can be considered. Moreover, the pest control component is not limited to formic acid, and other substances can be considered.

Since oxalic acid OX generates flammable gas (not shown) by heating, it is conceivable that the flammable gas is ignited when the formic acid generator 10 is heated. Therefore, as described above, by sandwiching the formic acid generator 10 between the lid body A10 and the container body A11, it is possible to prevent the flammable gas generated by the formic acid generator 10 from flowing into the combustion chamber 10d. It can be used safely.

Further, since the four discharge small holes A11h are provided in the lower part of the side surface A11g of the container body A11 on the side where the discharge port A10c is provided, the combustion gas generated in the combustion chamber 10d can be discharged. Further, since the state of heating by the gas cylinder 40 can be visually confirmed, it is possible to save the trouble of opening the lid A10 and taking out the formic acid generating part 10 from the container body A11 to check the heating state. The mite extermination device A can be easily operated.

[About the mite extermination method by the mite extermination device A]
Next, a mite extermination method by the mite extermination device A will be described with reference to FIGS. 4 and 5. The mite extermination method by the mite extermination device A includes the following arrangement step S1, blockage step S2, pest control component generation step S3, confirmation step S4, discharge step S5, and spraying step S6.

(Arrangement step S1)
First, the user of the mite extermination device A opens the lid portion A10 of the housing A1 of the mite extermination device A in the vicinity of the nest box C installed outdoors. Then, an appropriate amount of oxalic acid OX, which is a precursor of formic acid F, which is a mite extermination component, is arranged in the formic acid generator 10 provided inside the container body A11.

(Closing step S2)
Next, the lid A10 is closed to close the housing A1 with the formic acid generator 10 in which the oxalic acid OX is arranged in the arrangement step S1. As mentioned above, oxalic acid OX is a substance that, when taken into the body, deprives the blood of lime, invades the nervous system, and has a risk of acute poisoning, so care must be taken when handling it. Needs. Therefore, by putting the formic acid generator 10 in the formic acid generator 10 and further putting the formic acid generator 10 in the housing A1, the oxalic acid OX can be confined in the housing A1 and easily prevented from diffusing to the surroundings.

(Pest control component generation step S3)
Then, in the closing step S2, the oxalic acid OX arranged in the formic acid generator 10 is heated from the outside of the housing A1 to generate formic acid, which is a pest control component. Here, formic acid F can be generated from oxalic acid OX by heating the oxalic acid OX arranged in the formic acid generator 10 with the heating unit 4.

(Confirmation step S4)
Then, it is confirmed that the formic acid F produced in the pest control component generation step S3 flows out from the intake port A11e of the housing A1. Formic acid F flows out from the intake port A11e about 1 to 2 seconds after the start of heating of oxalic acid OX, which is a precursor of formic acid F.

(Discharge process S5)
Then, in the confirmation step S4, after confirming the outflow of formic acid F from the intake port A11e, the connecting port 21 for sucking the outside air OA into the housing A1 is attached to the connecting pipe A11f to start the intake. At this time, it is desirable to remove the intake device 2 from the connecting pipe A11f at the beginning when formic acid F is generated. When the formic acid F flows out from the connecting pipe A11f with the intake device 2 attached to the connecting pipe A11f, the formic acid F flows into the intake device 2 from the connecting port 21 and comes into contact with the fan 22 provided inside. This is because impurities contained in formic acid F generated when the acid OX is heated adhere to the fan 22, and the fan 22 does not rotate sufficiently, which causes a failure.

Further, if the intake device 2 is attached to the connecting pipe A11f while rotating the fan 22 to send the outside air OA toward the housing A1, the fan 22 of the intake device 2 is also connected to the connecting pipe A11f. In addition, it is possible to more reliably suppress the adhesion of impurities of formic acid F.

Then, the mixed gas MG of the outside air OA taken into the housing A1 and the formic acid F generated in the pest control component generation step S3 is discharged from the discharge port A10c. As a result, the intake gas mixed gas MG of the outside air OA and formic acid F can be discharged to the outside of the housing A1.

(Spraying step S6)
As shown in FIG. 4, the tip of the hose 3 is sprayed from the nest gate C1 of the nest box C into the inside of the nest box C with the mixed gas MG of the outside air OA and formic acid F discharged in the discharge step S5. As a result, it is possible to spray mites M (mainly Varroa destructor) parasitizing bees B (mainly honeybees) in the hive C. The spraying time is about 20 seconds per birdhouse. Although the mite M is an example of a pest, the mite M is not limited to the honeybee varroa destructor.

Further, at this time, since it is only necessary to insert the tip of the hose 3 into the nest gate C1, it is possible to save the trouble of opening the lid of the nest box C and spraying, and the mixed gas can be easily sprayed on the nest box C. ..

Dani M sprayed with a mixed gas of outside air and formic acid separates from the body of bee B and falls to the bottom of the hive C, and most of them die. In this way, the tick M can be exterminated from the bee B.

As described above, the pest control device and the pest control method according to the present invention can easily remove pests with a simple operation.
