JP 2004-107215 A

  In the method for controlling white ants of (1) above, the problem that the drug gives to the worker who sprays it, the problem that the sprayed drug erodes the ground and gives to the environment, and under the floor etc. There was a problem that it was difficult to work in a small place. The control method (1) is to kill existing white ants or to prevent white ants from entering thereafter.

  On the other hand, the method for controlling white ants in (2) is a method in which bait trees preferred by white ants are placed in an insecticidal container and the white ants that have entered the container aiming at the bait tree are killed. However, in this method, since the distance relationship between the position where the white ants are present and the position where the container is installed is unclear, even if the container is installed, it is difficult for the white ants to notice the presence of the feeding tree. There was a problem that it took a long time before the intrusion and the white ants could not be efficiently removed.

  The present invention has been made to solve the conventional problems as described above, and is an extremely efficient white ant control that actively attracts a wide range of white ants by using the white ant attractant pheromone to control and eliminate them. The purpose is to provide a device.

  The white ant control device of the present invention that achieves the above object has a cylindrical shape, and a white ant attractant is inserted into a container provided with a number of holes for white ant intrusion at the bottom and peripheral surface thereof. The gist of the present invention is that a bait control device is formed by inserting a bait tree, further inserting a white ant extermination member on the bait tree, and sealing the upper end opening of the container with a lid.

  In this case, the cylindrical container in the device of the present invention should have a pointed shape that can be easily embedded in the ground, or a shape that includes a flange portion (saddle) that can be easily erected on the ground. Good. The termite attractant to be inserted into the device of the present invention means a substance mainly composed of a pheromone secreted by a termite. The termite used in the present invention is typically a Yamato termite or a white termite, but is not limited thereto. In addition, these white ants can be exterminated regardless of their ecology, that is, queen, king, feather ant, vice queen, vice king, soldier ant, craft ant, old larva, primary larva and the like.

  According to the white ant control apparatus of the present invention having the above-described configuration, when this is buried or standing under the floor or the like, a large number of white ants are attracted by the white ant attractant (pheromone) inserted in the lower part of the container of the apparatus. It gathers around the container, and enters the container through a large number of holes around the container, aiming at the prey in the container. When the white ants that have entered the container devour the prey, they are brought into contact with or eaten the white ant extinguishing member impregnated with the white ant extinguishing agent on the top of the bait tree, and the insects are exterminated.

  In this way, the white ant control device of the present invention inserts a white ant attractant into the extermination container so that a large number of white ants are naturally attracted and killed by the pheromone effect in the extermination container. Therefore, the control and removal efficiency is extremely high. Moreover, since a wide range of white ants can be removed by installing one of the devices, the cost is low and the installation work is easy.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 and FIG. 2 are both examples of a white ant control apparatus embodying the present invention, and a white ant attractant 4, a bait tree 5, and a white ant extermination member 6 are arranged inside a cylindrical container 3 in order from the bottom. Has been inserted. The upper end opening of the container 3 as these insertion ports is sealed with a lid 7.

  That is, for the container 3, a plastic resin is often used, but any material having a certain degree of hardness and strength may be used, and is not particularly limited. As for the shape, a cylindrical shape or a rectangular tube shape is preferable, and the bottom portion 1 is sharpened at an acute angle as shown in FIG. 1 to facilitate insertion into the ground or soil concrete, or as shown in FIG. Furthermore, it is preferable to form a flat flange portion (saddle portion) 8 around the bottom portion 1 so as to be easily erected on the ground. A large number of holes 2 are provided in the bottom 1 and the peripheral surface of the container 3. These holes 2 are for releasing the pheromone emitted by the white ant attractant 4 around the container and for allowing the white ants attracted by the pheromone to enter the container.

  The white ant attractant 4 inserted in the lowermost part of the container 3 is mainly composed of a pheromone secreted by white ants, and is formed in a coin shape having a diameter substantially equal to the inner diameter of the container 3. In the example of FIG. 1, this white ant attractant 4 is inserted, and in the example of FIG. 2, two white ant attractants 4 are inserted in parallel, but the number of use is not limited to this.

  The feeding tree 5 inserted in the upper part of the white ant attractant 4 is preferably a cellulose-containing material that white ants prefer to eat, particularly Canadian aspen wood, and the required height to be fitted in the cylindrical container 3. It is formed in a cylindrical shape.

  The white ant extermination member 6 inserted in the upper part of the feeding tree 5 is formed by impregnating a white paper insecticide on a roll paper wound in a cylindrical shape having a size to be fitted in the container 3. The lid 7 seals the inside of the container 3 after insertion of the above-described white ant attractant 4, bait tree 5, and white ant extermination member 6, and is formed of resin.

  A white ant control device was produced according to the present invention. That is, a cylindrical container 3 having a sharp bottom portion 1 having an outer diameter of 55φ, a thickness of 2 mm, an inner diameter of 51 mm and a length of 200 mm was made of plastic resin, and a large number of holes 2 were formed in the bottom portion 1 and the peripheral surface portion. Each hole 2 has a size of 3φ, and four holes were formed on the circumferential surface of the bottom portion and 88 holes (eight vertical rows × 11) on the circumferential surface of the trunk portion.

  The white ant attractant 4 was first inserted into the container 3 from the upper end opening. This white ant attractant 4 was formed in a coin shape having a diameter of 48φ and a thickness of 5 mm, and one of them was inserted. Next, a bait tree 5 was inserted on the white ant attractant 4. The bait tree 5 is an aspen wood formed in a cylindrical shape having a diameter of 42φ and a length of 105 mm. Subsequently, a white ant extermination member 6 made of fibrous roll paper formed in a cylindrical shape having a diameter of 42φ and a length of 40 mm was inserted on the bait tree 5. Finally, the upper end opening of the container 3 was sealed with a lid 7.

  The white ant control effect of the device of the present invention having the above configuration was tested. That is, a test ground having an area of 4 m wide and 3 m long is prepared, and 750 white ants are released at the center of the diagonal line. Next, a total of 23 vertical ant control devices according to the present invention are arranged in a horizontal and horizontal direction in the form of a cross in a vertical and horizontal cross shape, 13 in 30 cm intervals in the horizontal direction and 10 in 30 cm intervals in the vertical direction. Installed in the ground. Then, it is allowed to stand for 7 days, and the number of white ants entering the 23 installed devices is observed every day.

  As a comparative example, 23 white ant control devices similar to those described above, in which the white ant attractant 4 is not inserted, were placed on the test ground under the same conditions as described above, and left for 7 days to enter the white ants that had entered these devices. Was observed every day.

  As a result, as shown in Table 1, in the white ant control apparatus of the present invention, infestation of white ants was observed in all 23 devices installed on the test ground on the seventh day. On the other hand, in the device of the comparative example, only about 40% of the devices were confirmed to have invaded by white ants on the seventh day. As a result, it has been found that the white ant control device of the present invention has an excellent effect of reliably attracting and removing white ants in the device in a short period of time regardless of the installation location.
