Description

[Detailed description of the invention]

[Industrial Field of Application] The present invention provides a method for detecting the presence of white matter using a white spot detector composed of a wooden attractant and a detector that is removably inserted into a storage hole of the attractant. For extermination, a white mosquito insecticide is applied to the storage hole and its vicinity, or a white mosquito insecticide storage container is provided with a storage hole in a wooden attractant, and the white mosquito insecticide is filled into the storage hole, A small white mite that uses wood with a particle size of 3 mm or less as a white mite attracting ingredient, powdered boric acid as a white mite repellent ingredient, and is composed of a powdered granule by mixing the above-mentioned white mite attracting ingredient and exterminating ingredient. It is related to drug removal. [Prior Art] The above-mentioned white spot detector is related to a proposal by the present inventor, and as mentioned above, it is composed of a wooden attractant and a wooden detector removably inserted into the storage hole of the attractant. be done. This is a device that is placed underground at appropriate intervals around the target building to detect the presence of white spots. The attractant is buried in the ground around the building, the detector is inserted into the receiving hole of the attractant, and the shield is covered with a shield to set the attractant. After doing so, inspect the white spot detector mentioned above several times a year. Inspection is performed by removing the shield, pulling out the detector, and observing itself and the inside of the storage hole. This means checking for the presence of white spots themselves or the presence of eating marks of white spots. If the presence of white mite is detected, the only option at present is to apply a commercially available white mite pesticide to the targeted area according to conventional techniques. On the other hand, a white ant repellent storage container filled with a white ant repellent is related to a proposal by the present inventor, which is buried underground to attract the surrounding white ant and make the repellent ingested orally. They are carried to the white ant's nest, but for now, there is no other option but to apply a commercially available white ant exterminator. [Problem to be Solved by the Invention] According to the research of the present inventor, when the result of the inspection of the above-mentioned white spot detector shows that a white spot actually exists or there are circumstances that lead to the existence of a white spot, the above-mentioned inducement is not detected. It is extremely appropriate to apply a slow-acting, non-repellent white mosquito repellent to the storage hole of the body and its surroundings, and to exterminate white mosquitoes using the mechanism described below. The above-mentioned white spot detector attracts white spots using an attractant and a detector, both of which are made of wood, and detects their presence. Therefore, the removal of white ants does not impair this attractiveness,
You should take advantage of this. That is, as mentioned above, the extermination of white ants is carried out using a non-repellent insecticide, and the white ants continue to flock to this detector and prefer to ingest this insecticide along with the attractant or detector. It is preferable to do so. It is also preferable that the pesticide be slow-acting, so that even if the white ant ingests it or adheres to its body surface, it will not die immediately and will be able to return to its own nest. This means that the pesticide moves and a closed loop of pesticide movement is formed between the nest and the detector. In this way, we can hope to destroy the nest of white ants. The same thing can be said about the above-mentioned white insect repellent storage container. However, to date, no redundant white pesticide has been proposed for use in the white spot detector or the white spot pesticide storage container. [Means for Solving the Problems] The gist of the configuration of the present invention is to provide a white detector consisting of a wooden attractant and a detector detachably inserted into a storage hole of the attractant. If the presence of a white mite is detected, a white mite insecticide is applied to the storage hole and its vicinity to exterminate it, or a white mite insecticide storage container with a storage hole in a wooden attractant is used to exterminate the insect. This is a white mite exterminator to be filled, which uses wood with a particle size of 3 mm or less as a white mite attracting ingredient, powdered boric acid as a white mite exterminator ingredient, and mixes the above-mentioned attracting ingredient and exterminating ingredient. A white mosquito repellent made up of powder and granules. First, the configuration of a white spot detector and a white spot repellent storage container to which the present invention is applied will be briefly described. The attractant of the white spot detector is made of a wood material preferred by white spots, such as pine or cedar. Although the shape is not particularly limited, since it is to be buried underground as described above, a shape that makes it easy to do so is suitable. For example, it is appropriate to make the external shape into a pile shape. The storage hole is formed to have a circular cross section about halfway from the upper end of the attractant. It is appropriate that this storage hole communicates with the outside through a groove formed in a cross shape from the lower end of the attractant. The purpose is to increase the effect of attracting white ants. The detector is made of the same wood material as the attractant and has a cylindrical shape with a diameter that can be inserted into and removed from the storage hole. It is convenient to configure the length so that it slightly protrudes from the upper end of the attractant when taking it out. The above-mentioned shielding body has a shape in which the peripheral edge of the lower surface thereof hangs down, and is constructed so that the attracting body buried in the ground and having the detector set thereon can be covered from above. On the other hand, the white mosquito repellent storage container is made of a wood material preferred by white mosquitoes, has a storage hole in a cubic attractant, and after filling the storage hole with the white mosquito repellent, covers it with a lid. The composition of the white mite repellent will be described in more detail as follows. That is, there is no reason to limit the attracting component to a specific one, as long as the attracting component is white and easy to handle. Among them, I particularly like the white ones, and those with a high bow-attracting effect are preferred. For example, wood materials such as pine and cedar, which are also used in the above-mentioned white spot detector and white spot repellent storage container, are suitable, and those finely ground into powder are suitable. Specifically, wood powder particles having a particle size of 3M or less, such as pine wood, are suitable. On the other hand, as the above-mentioned exterminating ingredient, it is possible to employ active ingredients of conventional white mite exterminators such as boric acid. In this way, by mixing the powder of the above-mentioned pine wood, etc. with the conventional white-spot insecticidal agent such as the above-mentioned boric acid, the white-spot insecticide of the present invention, etc.
It can constitute a pesticide. The mixing ratio can be determined appropriately depending on the case. [Function] Since the present invention is configured as described above, it is effective when the white spot detector detects white spot or as a white spot pesticide to be filled into a white spot pesticide storage container. . First, before explaining how to use this white spot repellent, the usage of the white spot detector and the white spot pesticide storage container will be explained. As mentioned above, the white spot detector is used by being buried in the ground at appropriate intervals around a house or other building to be inspected, and the detector is inserted into the storage hole of the attractant. , further covering the upper end of the attractant with a shield. After doing this, about two or three times a year, remove the shield of this white spot detector, pull out the detector, and observe the inside of the storage hole and the detector itself to see if there are any signs of the presence of white spots. Check whether or not. Inspect whether there is actually white spots or if there are food marks of white spots. If the inspection reveals no problems, the facility will be returned to its original state and will wait until the next inspection. On the other hand, when the presence of white mites is observed or suspected, the white mite repellent of the present invention is used. Its usage is as follows. As a result of the inspection of the white spot detector, if at least the presence of white spot is presumed as described above, the white spot exterminator of the present invention is administered to the storage hole of the attractant and its surroundings. do. Then, no detector is inserted into the attractant storage hole, and only the shielding plate is inserted as usual. However, when there is white around the white spot detector and a disinfectant is administered, the white spot is exterminated by the following mechanism. First, the white spots are attracted by the attracting action of the attractant of the white spot detector, and continue to invade the surrounding area and into the storage hole. The attracted white ant then ingests the applied white ant repellent or allows it to adhere to its body. That is, the above-mentioned white mite repellent of the present invention is constituted in a powder by mixing an attracting component having an effect of attracting white mites with an exterminating component having an exterminating effect against white mites. Since it has an attracting effect on white mites and the exterminating ingredients are appropriately diluted, the insecticidal effect on white mites tends to be relaxed and the insecticidal time tends to be extended. Unfortunately, as mentioned above, the white ant that has invaded the area around the white ant detector or into its storage hole will not be able to avoid the abovementioned white ant repellent, but will instead be attracted to it and end up ingesting it. White ants that ingest it do not die immediately. Furthermore, as mentioned above, since the white mosquito repellent is composed of powder and granules, it may adhere to the bodies of white mosquitoes while moving around the powder. Naturally, white ants that have had the white ants attached to their bodies do not die immediately. However, if the above white insecticide has been ingested or attached to the body,
Due to the action of the white insecticide, it will eventually die within a short period of time. The white ant that has ingested the white ant repellent or has it attached to its body will eventually return to its nest. Therefore, the lever insecticide forms a loop that circulates between the nest and the insect detector via the insect itself. By the way, white ants also clean the bodies of other white ants,
They have a habit of exchanging nutrients. As a result, the loop described above is formed, and the white ant repellent that is brought into the nest is eventually transmitted to all other white ant species, and finally to the white ant species that control reproduction (female workers and kings). ) and lead to the destruction of the white ant's nest. The same effect can be applied to the white fungicide storage container. [Examples] Example (1) Pine powder with a particle size of 3M or less was used as a component to attract white mites, and powdered boric acid was used as a component to exterminate white mites. The pine powder and the boric acid powder were mixed at a volume ratio of 50:50 to form a white spot repellent. Reference Example (1) Pine powder with a particle size of 3 mm or less was used as an ingredient to attract white ants, and powdered boric acid was used as an ingredient to exterminate white ants. The above pine powder and the above powdered boric acid were mixed at a volume ratio of 70:30 to form a white pest control agent. The white fungus pesticides of Example (1) and Reference Example (1) above are:
When a white spot is detected by the white spot detector described above, it is charged into the storage hole and sprayed around the spot, or is used by being filled into a white spot pesticide storage container, but here,
Instead of the above, each person placed a white ant in a petri dish containing an anticide, ingested it or allowed it to adhere to the body, and then transferred it to a petri dish without an anticide to observe its mortality. First, for both Example (1) and Reference Example (1), two petri dishes were each placed with filter paper, and the corresponding white insecticide was evenly distributed on the filter paper, and the water was souffled. 100 Yamato termites were placed in each container and left for 24 hours. The temperature conditions at this time are as shown in FIG. After this, only the surviving white ants were transferred to another Petri dish lined with filter paper and observed for 10 days. (No white ant repellent was added to this Petri dish.) During this period, dead white ant were removed every day at 10 o'clock, and the cumulative number of deaths was recorded. The results are shown in FIG. In this way, in the case of the white spot repellent of Example (1), 2
The cumulative mortality rate exceeds 50% in one day and approximately 85% in 10 days. On the other hand, in the case of the white spot repellent of Reference Example (1), the cumulative mortality rate was approximately 20 cm in 5 days and approximately 40 cm in 10 days. Therefore, from the comparison results between Example (1) and Reference Example (1), it can be seen that by appropriately selecting the ratio of the exterminating component and the attracting component, a moderately slow-acting white mosquito repellent can be obtained. For reference, an example of a white spot detector and a white spot repellent storage container that is used to spray the white spot pesticide of the present invention in and around the area when a white spot is detected will be briefly described. . As shown in Fig. 3, this consists of a pile-shaped attractor (■), a detector (3) that is removably inserted into a storage hole (2) in the center, and a shield that has a disc-shaped recess (1) at its lower end. It is composed of a body 5. A cross-shaped groove 6 is formed in the lower part of the attractant 1 when viewed from below, through which the outside of the attractant 1 and the storage hole 2 are communicated. The attractant 1 and the detector 3 are made of pine wood. This white spot detector is used by being buried as shown in FIG. In the case of a white pesticide storage container, as shown in FIG. 4, a storage hole 12 is provided in the center of a cubic attractant 11 with sides of about 10 cm, and the storage hole 12 is covered with a lid 13. The lower part of the attractant 11 has a cross-shaped groove 1 when viewed from below.
6 is formed, through which the outside of the attractant 11 and the storage hole 12 are communicated. The attractant 11 is made of pine wood. This white insecticide storage container is used by being buried underground. The usage is as described above in both cases. [Effects of the Invention] The insecticidal agent of the present invention has a good insecticidal effect because the insecticide approaches the insects without repelling them. By appropriately adjusting the ratio of the attracting component and the exterminating component, it is possible to create a slow-acting white spot repellent with an appropriately delayed insecticidal effect, and when this is sprayed on the white spot detector and its surroundings. By the movement of the white ant itself, a loop of movement of the white ant exterminator is formed between the spraying position and the nest, and the nest of the white ant can be destroyed. The same can be said about the pesticide storage container. This white fungus pesticide is in the form of powder and granules and does not have permeability like a liquid agent, so it is difficult to diffuse into the soil and is unlikely to cause environmental pollution. Furthermore, since it is difficult to diffuse, a uniform and stable state can be maintained. Furthermore, unlike liquid agents, they are less likely to be sucked into the human body from the respiratory tract when sprayed. Since no organic solvents are used, there is no need to worry about fire.
