Guide to Argentine Ant Control (revised version), published by the Ministry of the Environment, Natural Environment Bureau, Wildlife Division, Alien Life Control Office, July 2013 Argentine ant simultaneous control manual, Argentine ant countermeasures wide area administrative council (Hiroshima Prefectural Natural Environment Division and other 5 local government departments), March 2011

  In the above-mentioned prior products and Non-Patent Documents 1 and 2 and Patent Document 1, when the dish, microtube, or storage body falls down due to external force such as wind, human body, or animal contact, the chemical liquid spills out, and the chemical liquid cannot be retained. In addition to the problem of polluting the environment, the exposed area of the chemical solution that comes into contact with air is large, so the drying speed of the chemical solution is high. As a result, the concentration of the chemical solution is increased, and the components dissolved in the chemical solution are deposited. Has a problem that the argentine ant intake time is short because it dries.

  In the above-mentioned Patent Documents 2 and 3, since the mouth of the container is closed with a substance having a capillary force such as a sponge or a core material, the temperature of air that has entered the container due to gas-liquid exchange due to ingestion of cockroaches increases due to sunlight irradiation, etc. As a result of the volume expansion, the air pressure in the container rises, causing a problem that the chemical solution is pushed out.

  In order to solve the above-mentioned problem, the invention according to claim 1 is characterized in that the mouth at one end is closed, the mouth at the opposite end is open, and the open mouth is inclined downward by having a large capillary force. Even in such a case, a thin pipe-shaped container in which the chemical solution to be stored does not move to the opening side is used. In addition, chemical solution leakage from the open port is prevented, Argentine ants are introduced into the chemical solution accommodated from the open port, and further, since the inside of the container is not a closed space, the chemical solution is impregnated immediately behind the open port, In addition, a pipe-shaped liquid holding hole with a hole penetrating in the center is attached to make an Argentine ant extermination device.

According to the second aspect of the present invention, an Argentine ant enters the inside of the pipe-shaped container by providing a portion where the chemical liquid is not exposed in the hole by installing a core pipe in the hole through which the liquid retaining liquid impregnated with the chemical liquid is penetrated. Make it easier.
The invention according to claim 3 is that the chemical liquid is supplied to the liquid retaining liquid by attaching one end of the thread or string having liquid conductivity to the liquid retaining liquid and immersing the opposite end in the liquid chemical. According to a fourth aspect of the present invention, a fringe is provided at one end of the open side of the pipe-shaped container, and one part of the fringe is formed linearly in a tangential direction at a position slightly away from the opening of the container, or the straight line A V-shaped groove is put on the back side of the fringe at a location corresponding to the above, and a straight line is formed by breaking the groove at the time of use, and when the container is placed sideways, the straight part is grounded. It is possible to prevent the intrusion of rainwater that accumulates on the ground when it is installed outdoors.

  The invention according to claim 5 has a structure in which a fringe is provided at one end of the open side of the pipe-shaped container, and the sealed packaging seal attached to the fringe is opened only halfway through the open mouth. By the seal remaining in the shape of a bowl at the upper part of the opening, it was possible to prevent rain from entering the inside of the container when installed outdoors. The invention described in claim 6 is to attach an insect intrusion prevention sheet plate provided with a slit or a hole of a minimum size into which an Argentine ant can enter around an open mouth which is inside a fringe portion to which a hermetic packaging seal is attached. . The invention according to claim 7 is a linear portion having a hole in the central portion that can be fixed at an arbitrary position when fitted on the outside of the pipe-shaped container, and that can be grounded when the container is installed sideways. By attaching a weight having at least one place around the container to one place or a plurality of places of the container, the container is prevented from moving by an external force such as wind.

  According to the above means, since the chemical solution does not move to the opening side even if the opening port of the container is turned downward due to a fall, and even if it moves, the movement is prevented by the liquid retaining liquid, so that the movement from the opening port is prevented. Leakage can be prevented. In addition, since the chemical solution is stored in a thin pipe-shaped container, the area of the chemical solution exposed on the open mouth side is small, and since the entrance and exit of air from the open port is suppressed by the liquid retaining liquid, the drying speed of the chemical solution is slow, In addition to keeping the intake time of Argentine ants long, the inside of the container becomes an open space, so the air pressure does not increase due to the temperature rise, and as a result, the chemical solution is not pushed out from the opening.

  A pipe-like liquid retaining liquid having a narrow pipe-like container closed at one end and a hole penetrating in the center will be described.

First, the inner diameter, thickness, length, material, and one end closing method of the pipe-shaped container will be described. The inner diameter at which the stored chemical liquid does not move to the opening side even when the opening of the container is directed downward is about 6 mm or less, while it is about 4 mm or more in consideration of the chemical solution storage capacity and ease of handling. Accordingly, the inner diameter is about 4 to 6 mm, and the exposed area of the chemical liquid stored in the container is small, so that the chemical liquid drying can be suppressed. The wall thickness is thick when priority is given to strength, and is thin when priority is given to heat fusion processing that requires flat pressing. The length is appropriate in consideration of the chemical capacity and ease of handling. The material should be plastic such as polypropylene, and the color should be transparent or close to that so that you can observe the remaining amount of chemicals and the intake behavior of Argentine ants.
One end is closed by integral molding of the pipe portion and the bottom portion. If the pipe is made of thermoplastic and is thin, it is heat-sealed flat and closed. The opening on the opposite side may be provided with a sealed packaging seal, a fringe for attaching an insect entry preventing sheet / plate, or may not be provided with a pipe shape. In the case of a pipe shape, a rubber plug may be used in addition to the hermetically sealed package for sealing the opening, or in the case of a thin wall pipe, it may be heat-sealed flat. In the case of heat-sealing, the heat-sealed part at the time of use is cut off with scissors.
In addition, although the cross section of the pipe-shaped container mentioned above assumes circular, rectangular shape or a triangular thing may be sufficient.

Next, the material, length, outer diameter, diameter of the hole penetrating through the center, air conductivity, and mounting position will be described. The material may be a natural fiber or synthetic fiber molded body, a paper or non-woven fabric wound, or a sponge as long as the chemical solution is maintained by capillary force. The length is about 10 mm, and the outer diameter is a size that is fixed by frictional force to the inner wall of the pipe-shaped container by being compressed at the time of mounting. The Argentine ant first attaches to the chemical solution of the retentive liquid exposed at the opening, and then enters the container through a hole penetrating the center of the retentive liquid. The smaller the diameter of this hole, the stronger the capillary force, the more difficult the chemical solution leaks, the larger the volume of the liquid retention liquid, the larger the liquid retention volume, the more the area exposed to the open mouth of the pipe-shaped container, the Argentina that can be taken at once The number of ants also increases.
On the other hand, the length of the Argentine ant worker ant is about 2.5 mm, the body height is about 1.6 mm, and the outer skin is soft, so it is said that the gap of about 1 mm can pass through. The diameter of the hole seems to be this limit diameter About 1 mm or more is necessary, and the larger this is, the more Argentine ants can enter the container at a time. In an outdoor intake test, it was confirmed that Argentine ants entered the inside of the pipe-shaped container through a hole with a diameter of 1.5 mm, and the inner diameter of the container was about 4 to 6 mm. The diameter of the liquid hole is suitably about 1.5 to 4 mm. Since the hole for penetrating the liquid retaining liquid is provided, a closed space is not formed in the pipe-shaped container.
Therefore, even if the air volume in the container expands in proportion to the absolute temperature, air escapes from the hole, so that no chemical liquid is pushed out due to an increase in air pressure that occurs when a closed space is formed. The position where the liquid retaining liquid is attached to the pipe-shaped container is preferable because the amount of the liquid chemical leaking from the liquid retentive liquid is stored in the container as far as it goes from the opening, considering the liquid chemical leakage from the liquid retaining liquid. However, considering the intake of Argentine ants, the closer to the open mouth, the better.
In the outdoor ingestion test, Argentine ants began to ingest immediately after installation when the end of the liquid retaining liquid was positioned 2 to 3 mm behind the opening of the pipe-shaped container. From this, the position where the liquid retaining liquid is attached to the pipe-shaped container is such that the end of the liquid retaining liquid is 2 to 3 mm deep from the opening of the container. When the liquid-retaining liquid is attached, the chemical liquid in the pipe-shaped container does not leak out from the opening unless an impact such as strong shaking is applied.

On the other hand, when the liquid retaining agent is attached to a pipe-shaped container whose inner diameter exceeds 6 mm when the contained chemical liquid moves to the opening side when the opening port is directed downward, the liquid chemical moved to the opening port side is blocked by the liquid retaining liquid. However, when the chemical solution moves, a closed space of air is generated in the container, and when the air is thermally expanded, the chemical solution is pushed out from the open port. Further, when the downward angle is brought close to the vertical, the chemical liquid leaks due to the weight of the chemical liquid.
If the inner diameter of the pipe-shaped container greatly exceeds 6 mm, even if the open port is installed sideways, the chemical solution moves toward the open port side. Therefore, a pipe-shaped container with a large inner diameter has the advantage that the chemical solution capacity is large. It should be avoided if leakage is considered.

The injection of the chemical solution into the pipe-shaped container is performed by inserting a needle-like tube to the bottom of the container so as to inject with a syringe and applying pressure so that bubbles do not enter. It is desirable that a slight gap is formed. If this gap does not exist, air enters the pipe-like container by gas-liquid exchange from the hole of the liquid holding liquid and is taken into the drug solution as a closed space until the chemical solution is reduced by ingestion of Argentine ants and the gap is generated. there is a possibility. This taken-in air causes volume expansion due to temperature rise, and there is a risk of pushing out the chemical solution from the opening of the pipe-shaped container.
In order to provide this gap, after attaching the liquid retaining liquid to the pipe-shaped container, the needle-like tube is inserted into the container from the hole of the liquid retaining liquid, and the liquid chemical is injected until it reaches the liquid retaining liquid to impregnate the liquid retaining liquid. Then, the chemical solution may be sucked back to such an extent that a slight gap is formed between the chemical solution and the retention liquid. Alternatively, after injecting a chemical solution into a pipe-shaped container in an amount that allows a slight gap between the chemical solution and the liquid holding solution, the liquid holding liquid impregnated with the chemical solution in advance may be attached to the container, or the liquid holding solution may be attached to the container. After mounting, the liquid retaining liquid may be impregnated with a drug solution with a syringe or the like.

  Boric acid is suitable for water-soluble insecticides because it is inexpensive and has low toxicity, and its solubility is 3.65, 11.4, and 37.9 g / 100 g water at 10, 50, and 100 ° C., respectively. Therefore, the mixing ratio in 100 g of water is about 3 g and dissolved in warm water. Argentine ants are omnivorous, and most preferred are liquids containing sugar such as aphids, scales of secretions, nectar, etc. Therefore, cheap and easily available sugar is suitable as an attractant to be mixed in water. The mixing ratio of water to water is about 20 to 25 g. A chemical solution in which 3 g of boric acid and 25 g of sugar are dissolved in 100 g of water is injected into a pipe-shaped container having an inner diameter of 5.8 mm and a length of 249 mm. When observed in an outdoor test conducted in the city, Argentine ants continuously ingested without any problems, and after 14 days, they entered the container to the bottom and ingested all the chemicals. In addition to sugar alone, Argentine ants were ingested without any problems even when sugar 10 g and honey 10 g were used, so honey may be used as an attractant, and the drug is oily and mixed with water May be used in combination with a surfactant.

A core pipe installed in the hole for retaining liquid according to claim 2 will be described. Argentine ants have the property of repelling water, so when the insecticide is water-soluble and the retentive liquid contains this chemical, the hole in the center of the retentive liquid is wet with water, It is difficult to enter the hole of the liquid retaining liquid. Therefore, by inserting a plastic core pipe made of polypropylene or the like into the hole of the liquid retaining liquid, the water is blocked and the Argentine ants can easily enter the hole of the liquid retaining liquid. In addition, by making many small holes in the core pipe, a part of the liquid retention is pushed into the small holes and exposed to the inner wall of the core pipe, and the Argentine ants are attracted by the chemical solution coming out of this exposed part and the core pipe And further enters the pipe-shaped container in which the chemical solution is stored.
Since the exposed portion is limited to a part of the inner wall of the core pipe, the Argentine ants can travel through the core pipe through the non-exposed portion.

The installation of a thread or string having liquid conductivity according to claim 3 will be described. Ingestion of Argentine ants begins with a small number of Argentine ants attaching to the exposed portion of the liquid retaining liquid installed immediately behind the opening of the pipe-shaped container, and then passing through the hole in the core pipe in the center of the liquid retaining liquid. A process of leaving a signpost pheromone when ingesting the chemical contained in the container and then returning to the nest, and then being guided by the signpost pheromone to cause a number of Argentine ants to gather in the chemical contained in the container. Become. If there is a gap between the chemical solution and the retentive liquid, if the chemical solution impregnated in the retentive liquid disappears before the Argentine ant enters the pipe-shaped container, the Argentine ant will enter the container. There is a high possibility of not entering.
Moreover, even if it enters the pipe-shaped container through the hole of the liquid retaining liquid, the certainty of reaching the chemical liquid is poor. Therefore, if one end of a thread or string having liquid conductivity is attached to the liquid retaining liquid and the other end is immersed in the liquid chemical, the liquid chemical is always supplied to the liquid retaining liquid, and the pipe passes through the hole of the liquid retaining liquid. After entering the container, it gathers in the thread or string, and in addition to that, it is guided to the main body of the drug solution, so that intake by a large number of Argentine ants can be realized continuously and in a short period of time. However, when the thread or string is lengthened until it reaches the bottom of the pipe-shaped container and the opening of the container is directed downward, the chemical moves along the thread or string to the opening and contacts the liquid retaining liquid. In conjunction with this, air that has been on the liquid retaining side of the container enters the chemical liquid and eventually moves to the bottom of the container while being replaced with the chemical liquid, so that a closed space is formed. Furthermore, this closed space is increased by gas-liquid exchange caused by ingestion of chemicals from Argentine ant retentate.
As a result, the chemical solution on the liquid retaining side is pushed out from the opening due to the volume expansion of the air due to the temperature rise. In the case of using a pipe-like container equipped with a liquid-retaining liquid to which a thread or string is attached, it is necessary to prevent the opening from facing downward. To prepare for the case where it falls downward, shorten the length of the thread or string from the bottom of the pipe-shaped container to the open mouth side so that the air does not move beyond the tip of the closed space. The amount of the chemical solution that may be pushed out from the opening may be suppressed by reducing the amount of.
Note that the number of threads or strings to be attached may be one or more.

A description will be given of making one place of the fringe described in claim 4 linear.
If there is no straight part to be grounded to the fringe provided at the opening of the pipe-shaped container, the container is easily rotated by an external force such as wind after the container is installed. To prevent this, make one fringe straight in the tangential direction at a position slightly away from the opening of the pipe-shaped container in advance, or insert a V-shaped groove on the back side of the part corresponding to the straight line. In use, the groove is broken to make it straight. By grounding this straight line portion, rotation of the pipe-shaped container is suppressed, and at the same time, the height between the straight line portion and the opening can be set, so that intrusion of rainwater that accumulates on the ground when installed outdoors can be suppressed.

The structure in which the hermetic packaging seal described in claim 5 is opened only halfway through the opening will be described.
When the pipe-shaped container is installed outdoors, if the opening of the container is completely open, it is not possible to suppress the intrusion of rain, and rainwater soaks into the liquid retaining liquid attached to the container, Furthermore, there is a risk that the effect may be reduced by entering the container and diluting the chemical solution.
Therefore, by increasing the area where the hermetic packaging seal is attached to the fringe by heat sealing, the seal that has been opened is made into a bowl-like shape at the top of the open mouth by making the structure more difficult to open. Try to remain. In the case of a pipe-shaped container not provided with a fringe, if the container is placed on its side with the opening cut obliquely and protruding forward, the protruding part becomes a ridge.

  The insect entry preventing sheet / plate according to claim 6 will be described. As described above, the inner diameter of the pipe-shaped container is about 4 to 6 mm, and the diameter of the hole for the liquid retaining liquid to be mounted immediately behind the opening of the container is about 1.5 to 4 mm. Accordingly, insects having a width of about 6 mm or less can enter the opening and take in the chemical liquid impregnated with the retentive liquid, and insects having a width of about 4 mm or less can enter the container through the hole of the retentive liquid. . The target insect of this Argentine ant extermination device is the Argentine ant, and it must be avoided to destroy other ecosystems by destroying other insects. In order to prevent insects larger than Argentine ants from entering the container, the minimum size that Argentine ants can enter around the open mouth inside the fringe area where a sealed packaging seal is attached or into the groove provided in the circumference Attach an insect intrusion prevention sheet plate with a slit of about 1.5 mm width or a hole with a diameter of that length. Attachment is performed by heat fusion or adhesion.

The weight which has the straight line part described in Claim 7 in at least one place of the periphery is described. When a pipe-shaped container is installed outdoors, the installation location may not only be moved by an external force such as being blown away by strong winds, but in the event of an impact caused by dropping, the chemical solution in the container may leak out from the opening. . In order to prevent this, a hole that can be fixed at an arbitrary position when fitted to the outside of the pipe-shaped container is provided at the center, and a weight having a straight portion at least at one place around the periphery is attached to the container. . As the weight material, stainless steel, plated iron, or mortar, which has a large specific gravity and is durable, is suitable. If there is a fringe at the opening, install the weight at one place on the bottom side of the pipe-shaped container, and if there is no fringe, attach one additional place on the opening side in addition to the bottom. By attaching the weight, it is possible to stably ground the pipe-shaped container when it is installed sideways. This weight becomes a passage when Argentine ants climb from the ground to the pipe-shaped container.
On the other hand, when the pipe-shaped container is used in the vertical position with the open port facing upward, the weight cannot be used. Instead, it is fastened to the retaining wall with an adhesive tape or an adhesive. In addition, the installation place of the pipe-shaped container was best on the line of Argentine ants, and in the outdoor test, the entry of Argentine ants to the container started immediately after installation on the line.

In FIG. 1, a pipe 1 having a core pipe 6 in the center is formed in a thin pipe-shaped container 5 whose one end is closed by integrally molding the pipe part 1, the bottom part 2 and the fringe 3 and the other end is an open port 4. The liquid retaining liquid 7 is mounted immediately behind the opening 4, and the chemical solution 8 is stored in a position where it does not come into contact with the liquid retaining liquid 7 impregnated with the chemical liquid 8, and then the container 5 is used horizontally. It is shown. The pipe-like container 5 can be stably installed by grounding the straight portion 10 of the weight 9 attached to the pipe portion 1 on the bottom 2 side and the straight portion 11 of the fringe 3.
An upper portion of the fringe 3 has a hermetic packaging seal 12 that remains without being peeled when opened to prevent intrusion of rainwater when installed outdoors. FIG. 3 shows the pipe-like container 5 before the hermetic packaging seal 12 is opened, and FIG. 4 shows the AA cross section of FIG. At the time of opening, the free portion 13 of the hermetic packaging seal 12 that is not in close contact with the fringe 3 is pinched with a finger and peeled off. Argentine ants can easily reach the opening 4 through the fringe 3.

  FIG. 2 shows a form in which a pipe-like container 5 in which one end of a pipe portion 1 made of thermoplastic resin is closed by heat-sealing flat is used in a horizontal position. The difference from the pipe-shaped container 5 shown in FIG. 1 is that the fringe 3 is not provided in the opening 4, the sealed packaging seal 12 that seals the opening 4 is completely opened, and the pipe portion on the opening 4 side. The weight 9 is attached to 1. The closer the weight 9 is to the opening 4, the more Argentine ants can reach the opening 4 through the weight 9. Since the pipe-shaped container 5 that is heat-sealed and closed flatly can use a commercially available straw, it can be manufactured inexpensively and easily.

  5, one end of a thread or string 14 having liquid conductivity is attached to the liquid retaining liquid 7 of the pipe-shaped container 5 shown in FIG. 3, and the other end thereof is immersed in the chemical solution 8, and further, the back side of the fringe 3 A pipe-like container 5 provided with a V-shaped groove 15 is shown. By connecting the liquid retaining liquid 7 and the chemical liquid 8 with a thread or string 14, the chemical liquid 8 is supplied to the liquid retaining liquid 7 by capillary action, and Argentine ants entering the pipe-shaped container are clustered on the thread or string 14. Since the chemical solution 8 is induced, intake by a large number of Argentine ants is realized continuously and in a short period of time. The hermetic packaging seal 12 is completely integrated with the fringe 3, and a V-shaped groove 15 is provided on the back side of the fringe 3, so that when the seal 12 is opened, it is below the groove 15. Since the knob 15 can be pinched with a finger to fold the groove 15 and the seal 12 can be peeled off, the peeling becomes easier than when the thin free portion 13 is pinched and peeled off.

  FIG. 6 is an enlarged view of the liquid retaining liquid 7 having the core pipe 6 provided with many small holes 17 in the center. Part of the liquid retaining liquid 7 is pushed out from the small hole 17 and exposed to the inner wall 18 of the core pipe 6, and the Argentine ants are drawn to the chemical solution 8 coming out from the exposed portion 19 and proceed to the back of the core pipe 6. Furthermore, it enters the pipe-shaped container 5 and ingests the chemical solution 8 contained in the container. Since the inner wall 18 other than the exposed portion 19 is the non-exposed portion 20 where the liquid retaining liquid 7 is not exposed, the Argentine ants travel to the back of the core pipe 6 through the non-exposed portion 20 where there is no possibility of contact with the chemical solution 8. Can do.

  7 shows the attachment position 21 of the sealed packaging seal 12 attached to the fringe 3 of the pipe-like container 5 and the attachment position 23 of the insect intrusion prevention sheet plate 22 shown in FIG. 8 with the liquid retaining liquid 7 removed. Yes. The mounting position 21 of the hermetic packaging seal 12 is composed of a ring-shaped portion 24 and a circular piece-shaped portion 25. When the seal 12 is peeled off from the straight portion 11 of the fringe 3, the ring-shaped portion 24 is easily opened. When reaching the cut end portion 25 of the circle, the length to be peeled off becomes abruptly long, so that it cannot be opened easily. As a result, the sealed seal 12 remains in the shape of a bowl at the top of the opening 4, and the intrusion of rainfall into the opening 4 is suppressed. The inside of the ring-shaped portion 24 is an attachment position 23 for the insect entry preventing sheet / plate 22, and the sheet / plate 22 is attached to the fringe 3 before the hermetic packaging seal 12.

  FIG. 8 shows a ring-shaped groove provided in a portion of the fringe 3 corresponding to the attachment position 23 of the sheet plate 22 when there is an obstacle to the installation of the sealed packaging seal 12 because the insect entry prevention sheet plate 22 is thick. 26 is shown. If the insect entry preventing sheet plate 22 is attached to the groove 26, the sheet plate 22 does not jump out before the fringe 3, and the hermetic packaging seal 12 can be attached to the fringe 3 without any trouble. The insect entry preventing sheet plate 22 is provided with a slit 27 through which Argentine ants can enter, but larger insects cannot enter.

The destruction of ecosystems and agricultural damage due to the invasion of Argentine ants has become a global problem, and the invasion / breeding continues to spread due to the strength of the fertility that forms a large colony by multiple queen ants, and eradication is difficult It is. In Japan, many local governments are playing a central role in installing many bait-containing extermination devices outside the invasion / breeding area, and it has been reported that the removal has a certain effect. One of the bait agents is a boric acid aqueous solution mixed with sugar, which is inexpensive and has low toxicity, and is considered suitable for simultaneous extermination. Since many extermination devices that contain this chemical solution are required for simultaneous extermination, the extermination device is required to be inexpensive and have high liquid retention and storage properties.
In addition, a structure in which Argentine ants can easily take chemicals and stability against wind and rain are also required. The present invention is based on a simple structure in which a chemical liquid is impregnated immediately behind the opening of a thin pipe-shaped container and a pipe-shaped liquid retaining liquid having a through-hole is mounted. Argentine ant extermination machine with all necessary requirements. In addition to this simple structure, mass production of the present invention is possible by using a thermoplastic resin that can be thermally fused to a pipe-shaped container. Its use can be expected not only in Japan but also overseas.
