DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a termite-controlling agent excellent in operability and excellent in termite-controlling effect, and a method for controlling termites using the same.

[0002]

2. Description of the Related Art In general, pesticides (pesticidal compounds) are often used to control pests. However, the use of pesticides can harm not only pests but also other organisms such as humans and livestock. For this reason, a method using a natural enemy has been used as a method of extermination that does not harm other living things such as humans and livestock.

As a specific example of a method utilizing a natural enemy, there is a method utilizing a natural enemy filamentous fungus, and methods for controlling longhorn beetles are disclosed in JP-A-4-202104 and JP-A-63-258803. This is disclosed in Japanese Patent Publication No.

[0004] On the other hand, in order to control termites, conventionally, a method of spraying an oil solution or an emulsion of an organophosphorus insecticide or a pyrethroid insecticide on wood or soil, or injecting it into a wood part has been carried out.

[0005] In recent years, however, the effects of these drugs on humans and livestock, environmental pollution, and the like have been regarded as problems.
Further, since the processing place is often a narrow space such as under the floor, there are problems such as difficulty in work and adverse effects on the health of workers.

Accordingly, a method for controlling termites using natural enemy filamentous fungi has been studied. A method for controlling termites using a natural enemy filamentous fungus is described in, for example, Japanese Patent Application Laid-Open No. 4-504413.
And JP-A-8-301713. However, the extermination method disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 8-301713 has extremely poor stability of natural enemy filamentous fungi in a natural environment. For example, when natural enemy filamentous fungi are sprayed, the natural enemy filamentous fungi die in a short time. To do
There is a disadvantage that the persistence of the extermination effect cannot be expected.
Further, the method disclosed in Japanese Patent Application Laid-Open No. 4-504413 has a drawback that the method of use and the place of use are limited because a specific device is used. Also, due to the poor stability of natural enemy filamentous fungi, it is necessary to pay attention when storing and transporting the pesticide using natural enemy filamentous fungi. Tokuhyo Hei 5-5086
No. 45 discloses a method of preserving using a packaging material in order to enhance the stability of natural enemy fungi and their conidia at the time of storage and transportation, but it is not possible to obtain a sufficient control effect. There is a disadvantage that.

[0007]

DETAILED DESCRIPTION OF THE INVENTION The termite-controlling agent of the present invention is a cellulose comprising at least one termite-inducing substance selected from the group consisting of an aqueous extract of pine wood, rosin, rosin, and a termite-inducing pheromone. A termite-controlling agent comprising a sheet made of a termite and a lethal composition for termites, wherein the whole or a part of the lethal composition has a structure wrapped by the cellulose sheet, or It has a structure in which the cellulose sheet is brought into contact with the whole or a part of the product.

The termiticide of the present invention does not harm organisms other than termites because it contains a termite fungus in the killing composition for termites. Further, since the termite-controlling agent of the present invention contains a cellulose sheet containing a termite-inducing substance, the effect of attracting termites approaching to eat cellulose can be further enhanced. Therefore, the number of termites that come into contact with the termite-controlling agent of the present invention increases, so that the specificity of the controlling effect can be further enhanced. The termite pesticide of the present invention is a pesticide utilizing the habit that termites eat cellulose and the habit that termites are attracted to water extracts of pine wood, rosin, rosin, termite-inducing pheromones, and the like, Exhibits a surprisingly high control effect compared to conventional termite control agents. Furthermore, when the method of use and the place of use are highly flexible, and furthermore, when a film of a polymer compound is provided between the lethal composition and the cellulose sheet, the stability of the natural enemy filamentous fungus is increased, and the termite control effect Has an excellent effect that can be maintained for a longer time.

The termites that can be controlled by the termite-controlling agent of the present invention are not particularly limited, but specific examples include house termites, yamato termites, dike termites, and American termites.

[0012] The natural enemy filamentous fungus may be any filamentous fungus that can kill termites by infesting the termites, and specifically, Beauverian bronniati (Beaunia).
veria brongniartii, Beauveria Bassiana (Beau)
veria bassiana), Beauveri
a amorpha), Metallidium anisoprie (Metarhiz)
ium anisopliae), Verticillium recany (Vertici
llium lecanii) and the like. These filamentous fungi can be isolated, for example, from the termites that have infested and died in the field. Among the filamentous fungi, Beauveria blonniati is particularly preferable because of its excellent mortality against infection with termites and its immediate effect on termites.

In the present invention, examples of the lethal composition against termites include the above-mentioned natural enemy fungi and / or a culture carrier containing the culture thereof.

Specific examples of the culture carrier are described below. As a solid culture carrier, mineral powder (for example, silicic acid,
Kaolin, activated carbon, bentonite, montmorillonite,
Diatomaceous earth, talc, clay, calcium carbonate, alumina, acid clay, talc, laurite, mica, silica sand, ammonium sulfate, etc.), powder derived from plants or their components (tree, soybean, wheat, tobacco, starch, cellulose) And clathrates such as cyclodextrin. These are processed into dosage forms such as powders, granules, tablets, pellets and the like. In addition, synthetic fibers and processed fibers thereof (fibers made of polyethylene, nylon, polyvinyl chloride, polyvinylidene chloride, polyester, polypropylene, vinylon, and the like and processed fibers thereof), fibers derived from animals or plants, and fibers of inorganic materials and Those textile products (cellulose, glue, silk, cotton, wool, paper, cloth, non-woven fabric,
Fibers such as woven fabric and leather and their fiber processed products) are exemplified. These can be processed into a dosage form such as a band or a sheet, and the resulting processed product can be used as a culture carrier.

Further, hydrocarbons (liquid paraffin, vaseline, paraffin, etc.), silicons (dimethylsiloxane, colloidal silica, bentonite, etc.), alcohols (ethanol, stearyl alcohol, lauryl alcohol, polyethylene glycol, ethylene glycol, glycerin) And the like, carboxylic acids (eg, lauric acid, stearic acid, etc.), esters (eg, termite, lanolin, etc.). These can be processed into a cream or the like, and the obtained processed product can be used as a culture carrier.

Among the above-mentioned culture carriers, from the viewpoints of good growth of filamentous fungi, the fact that the carrier itself becomes an attractant bait, and that it is easily degraded in nature, etc., any one of a sheet, granule or powder made of cellulose is preferred. Such culture carriers are preferred.

Number of viable fungi on the culture carrier (cell density)
^May be a value sufficient to infect and kill termites. For example, based on the unit area of a culture carrier, from the viewpoint of exhibiting a sufficient control effect, 105 cells (cells) / cm ² (Culture carrier unit area) or more, and preferably 10 ⁷ cells / cm ² (culture carrier unit area) or more. The number of viable natural fungi (cell density) in the culture carrier can be freely selected within the above-mentioned density range according to the purpose. The number of viable cells is measured by the dilution plate method using the viable cell number per unit area (cell density).
Can be measured.

In the present invention, the cellulose sheet for enclosing the termite-killing composition or contacting it with the termite-killing composition is not particularly limited. Examples thereof include corrugated paper, art paper, coated paper, and fools. Examples include paper, Kent paper, kraft paper, roll paper, glassine paper, Indian paper, condenser paper, Japanese paper, and the like. Among the above-mentioned cellulose sheets, corrugated paper and kraft paper are preferred from the viewpoint of good attraction and eating ability of termites. As the corrugated paper, single-sided corrugated paper is preferable. By using single-sided corrugated paper, a corrugated shape can be arranged on the outer surface of the termite control agent. In the termite control agent of the present invention, it is preferable that all or a part of the outer surface of the termite control agent has a corrugated shape. By arranging the corrugated shape on the outer surface, it is preferable because the eating ability of termites is improved, the effective eating area is increased, and more termites can be eaten. The wave height (step height) of the corrugated plate-like shape is preferably 2 to 6 mm from the viewpoint of obtaining a sufficient termite-eating property and an effective eating area. The thickness of the corrugated paper is preferably 0.3 mm or more from the viewpoint of strength, and 0.8 mm or less from the viewpoint of ease of termite eating and piercing to reach the lethal composition.

The structural features of the termiticide of the present invention have two aspects. One embodiment has a structure in which the whole or a part of the lethal composition is wrapped by a cellulose sheet, and another embodiment has a structure in which the whole or a part of the lethal composition is brought into contact with a cellulose sheet. .

In the embodiment in which the lethal composition is wrapped in a cellulose sheet, only one kind of cellulose sheet may be used, or two or more kinds of cellulose sheets may be used. For example, when wrapping a lethal composition using two or more kinds, it is preferable to use corrugated paper and kraft paper as the cellulose sheet. When two or more kinds are used, the termite-inducing substance may be contained in at least one kind of cellulose sheet.

For example, a preferable structure is to wrap the whole or a part of the lethal composition in kraft paper, and wrap the wrapped body in corrugated paper containing a termite-inducing substance. Alternatively, a structure in which the whole or a part of the lethal composition is wrapped with corrugated paper containing a termite-inducing substance, and the wrapped body is further wrapped with kraft paper, is also preferably mentioned.
In these cases, from the viewpoint of termites eating corrugated cardboard or kraft paper to facilitate contact with spores of natural enemy filamentous fungi, it is preferable to appropriately provide an opening when wrapping with corrugated cardboard or kraft paper. Here, the case where the termite-inducing substance is contained only in corrugated paper is described, but it may also be contained in kraft paper or may be contained only in kraft paper.

In the embodiment in which the cellulose sheet is brought into contact with the whole or a part of the lethal composition, only one kind or two or more kinds of cellulose sheets may be used.
When two or more kinds are used, the termite-inducing substance may be contained in at least one kind of cellulose sheet. In this embodiment, by contacting the cellulose sheet, the edible and attractive properties can be improved, and the structure of the lethal composition can be easily reinforced. From the viewpoint of reinforcing the structure of the lethal composition, it is preferable to use a cellulose sheet such as cardboard to contact the lethal composition.

The termite-inducing substance contained in the cellulose sheet may be any substance that attracts termites.
Pinewood water extracts, rosin, rosin or termite-inducing pheromones are particularly preferred. The termite-inducing substances can be used alone or in combination. When rosin and rosin are used, the amount of rosin and rosin per 1 cm ^{3 of the} cellulose sheet is preferably 0.001 to 0.5 g.

The method of incorporating the pine wood extract, rosin, and rosin into the cellulose sheet is not particularly limited. For example, the pine wood hot water extract may be used as it is, or the pine wood or rosin may be replaced with ethanol or the like. It can be contained in a cellulose sheet by dissolving it in alcohol and impregnating it. The termite-inducing pheromone is not particularly limited as long as it is a pheromone having a property of attracting termites, and examples thereof include a signpost pheromone.

Furthermore, the termiticide of the present invention is a lethal composition which is a culture carrier on which natural enemy filamentous fungi are grown, from the viewpoint of dramatically improving the stability of natural enemy filamentous fungi and increasing the sustainability of the control effect. Between the product and the cellulose sheet, the non-breathable, water-impermeable composition is wrapped with a cellulose sheet through a membrane made of a water-impermeable polymer compound, or through a membrane made of the polymer compound. It is good also as a structure which made the sheet made from cellulose contact a lethal composition.

Examples of the film made of the polymer compound include a polyolefin compound, a polyamide compound, a polyester compound, an acrylonitrile compound and the like. From the viewpoint of strength and ease of processing, polyethylene,
A film of a polyolefin compound such as polypropylene is preferred. The thickness of such a film is not particularly limited, but may be a relatively thin film-like film or a relatively thick sheet-like film. Specifically, the film thickness is preferably from 5 to 200 μm, more preferably from 5 to 50 μm.

The method for providing the membrane made of the polymer compound is not particularly limited. For example, a bag is prepared using a membrane made of the polymer compound, and a culture carrier is stored in the bag. It can be produced by sandwiching a culture carrier using two membranes composed of a polymer compound. Further, a method of coating the surface of a cellulose sheet with a material made of a polymer compound and enclosing the culture carrier may be used. Alternatively, for example, a cellulose sheet previously coated with a polymer compound, such as kitchen paper or kraft paper coated with a polymer material, may be used.

In the case of providing a film made of the above-mentioned polymer compound, it is preferable to cover the whole of the lethal composition against termites from the viewpoint of the long-term stability of the cells, etc. From the viewpoint of exerting the effect, it is preferable to provide an opening or a vent as appropriate, or make the membrane into a mesh shape so that the termites and the spores of the natural enemy filamentous fungus can easily come into contact with each other. In the case where the whole of the lethal composition is wrapped with a film made of a polymer compound, the film made of the polymer compound is broken and a hole is formed with the consumption of a termite cellulose sheet. And
The termites are brought into contact with the spores of the natural enemy filamentous fungi through the holes to exert a termite-controlling effect.

The external dimensions (plane) of the termite control agent of the present invention are not particularly limited, and a preferable numerical value may be selected depending on the mode of use. Further, from the viewpoint of strength and ease of handling, the thickness is preferably 5 to 30 mm.

The shape of the termiticide of the present invention is not particularly limited as long as it has the structure described above.

Hereinafter, the termite control agent of the present invention will be described with reference to the drawings.
