Description

  The present invention relates to a pest capturing sheet used for capturing only pests without capturing beneficial insects and legally protected birds and beasts.

It is effective to use pesticides for pest control in the agricultural field, but protect the crops from pest damage without using pesticides as much as possible from the environmental and safety aspects such as residual pesticides on the soil, groundwater system and crops. Is desired.
In response to this request, the sheet on which the pressure-sensitive adhesive layer is formed is colored in the color preferred by the pests to be captured, the pests are attracted by the color, and are adhered to the pressure-sensitive adhesive layer and captured, or the pressure-sensitive adhesive formed on the sheet A method for capturing male pests gathered in the adhesive layer by mixing a female sex pheromone attractant into the layer is proposed.
However, since it is difficult to capture a large number of pests in the above method, light is used as one of the pest attracting means, and the entire surface of the cylindrical sheet is coated on the outer peripheral surface or a streaky or dot-shaped partial coating. A cylindrical pest capture sheet with an adhesive layer formed by the above is arranged so as to surround a pest attracting light that emits irradiation light by using a solar cell or a storage battery as a power source, and the insect flying in the irradiation light from the pest attracting light is adhesive. In order to increase the number of flying pests, it is proposed to color the capture sheet in a color preferred by the pests or to mix a pest sex pheromone attractant into the adhesive layer. (For example, refer to Patent Document 1). There is also an invention in which a pressure-sensitive adhesive layer is formed on the surface of a film colored in a color preferred by pests, a light source is provided on the back side of the film, and flying insects that are attracted by light are adhered and captured on the pressure-sensitive adhesive layer (For example, refer to Patent Document 2).

  By the way, there are pests and beneficial insects in flying insects. In the agricultural field, agricultural personnel purchase beneficial insects and intentionally release beneficial insects that eat pests in response to the time of the occurrence of pests, or release flower honey bees, bees, etc. for pollination purposes during flowering time Things have been done. In addition, the law on the protection and hunting of birds and animals prohibits the capture of more than 70 types of legally protected birds and more than 10 types of mammals, and prohibits the installation of bird cages as a means of capture.

The method of capturing flying insects by the conventional sheet method uses a capture sheet having a configuration in which the pressure-sensitive adhesive layer is applied to the entire surface or a streaky or dot-shaped portion and the surface of the pressure-sensitive adhesive layer is positioned on the outermost side. If the animal is smaller than this size, there is a problem that beneficial insects and birds are caught indiscriminately in addition to pests.
In addition, if the sheet is colored in a color preferred by pests or a sex pheromone attractant is mixed in the adhesive, a sheet of a different color is produced for each type of pest, or the type of pest is added to the adhesive. The sex pheromone attractant must be mixed, and the sheet with the adhesive layer cannot be used to capture other types of pests. It was necessary to do so, and the cost was raised.
Therefore, the invention of the present application is attached to the sheet on which the pressure-sensitive adhesive layer is formed, and by attaching a mesh forming member having a mesh larger than the pest body and smaller than the beneficial insect body, the beneficial insect larger than the mesh size is not captured. An object of the present invention is to provide a pest capture sheet that can be captured by adhering only pests to the pressure-sensitive adhesive layer surface.

In order to achieve the above object, the invention according to claim 1 of the present invention is characterized in that a pressure-sensitive adhesive layer is formed on one or both sides of a translucent sheet, and the pressure-sensitive adhesive layer surface is formed on the surface of the pressure-sensitive adhesive layer. so that the mesh member surface is positioned to protrude outward direction than the layer thickness of the adhesive layer, wherein the mesh formed smaller than the thickness of the member, and the pressure-sensitive adhesive layer surface and the mesh member surface Attach a mesh-forming member so as to form an uneven surface, and the mesh of the mesh-forming member is larger than the body of the pest to be captured in relation to the installation location, and coexists with the pest and is released for pollination purposes at the flowering time It is characterized by being formed smaller than the body of a beneficial insect .
The invention according to claim 2 is characterized in that the mesh forming member is colored in a color preferred by the pest .
According to a third aspect of the invention, the mesh member is characterized by sex pheromone attractant to attract pests capture object is being deposited.

In the present invention, since the mesh forming member having a mesh larger than the body of the flying pest to be captured is smaller than the body size of the beneficial insect is attached to the surface of the pressure-sensitive adhesive layer, even if the beneficial insect is flying, the mesh forming member is attached to the mesh forming member. There is an effect that only a pest is caught and caught without the body part coming into contact and the whole body being caught without being caught by the adhesive layer.
By using a mesh forming member with a mesh size smaller than the size of the protected birds and animals that live near the installation location while referring to the monthly list of protected birds and beasts, the protected birds and animals only pull the pests to the adhesive layer without capturing them. The effect is that it can be captured.
Further, since the mesh forming member is provided on the surface of the pressure-sensitive adhesive layer, the pressure-sensitive adhesive does not attract even if an infant or a person comes into contact with it, and it is safe.
It is sufficient to attach the network forming member to the surface of the pressure-sensitive adhesive layer of the sheet with the pressure-sensitive adhesive, coloring the net-forming member in the desired color of the flying pest to be captured or adhering the sex pheromone attractant of the pest to be captured. There is no need to color the sheet on which the pressure-sensitive adhesive layer is formed for each flying insect to be captured, and there is no need to mix a sex pheromone attractant in the pressure-sensitive adhesive layer, thereby reducing the cost of the product. .
By attaching the sex pheromone attractant to the mesh forming member, there is an effect that the number of flying pests can be increased.

  An adhesive layer is formed on one or both surfaces of the translucent sheet, a mesh forming member is provided on the surface of the adhesive layer, and the mesh size of the mesh forming member is larger than the body of the pest to be captured. It is possible to capture only pests and reduce the cost by forming smaller than the body of beneficial insects, coloring only the mesh forming member with the favorite color of the target insects to be captured or attaching a sex pheromone attractant .

FIG. 1 is a partially cutaway cross-sectional view of a pest capturing sheet, FIG. 2 is a configuration explanatory view of the pest capturing sheet, and FIG. 3 is a plan view of the pest capturing sheet.
1 to 3, a sheet 1 is a colorless transparent or translucent sheet, and is made of a synthetic resin film having flexibility and appropriate strength. For example, it is conceivable to use a film of polyethylene, polypropylene, polyvinyl chloride, PET, cellophane, vinylon, acrylic or the like. The thickness of the sheet 1 is preferably about 0.01 to 0.04 mm, but is not particularly limited as long as it is 0.04 mm or more as long as it has translucency and flexibility.

  An adhesive layer 2 is formed on the surface of the sheet 1. The pressure-sensitive adhesive layer 2 is formed by applying a light-transmitting and pressure-sensitive adhesive with a uniform thickness on the surface of the sheet. The pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer 2 uses a pressure-sensitive adhesive such as a known rubber-based elastomer or acrylic resin that is used for a squirrel catching sheet, a mouse catching sheet, or the like.

A mesh forming member 3 is attached to the surface of the pressure-sensitive adhesive layer 2 by polymerization adhesion. The mesh forming member 3 is made of a long and thin linear material such as synthetic resin yarn having rust resistance and flexibility, and is entangled to form a mesh 4 having a rhombic shape. The relationship between the thickness W of the mesh forming member 3 and the layer thickness N of the pressure-sensitive adhesive layer 2 is configured such that W> N, and the pressure-sensitive adhesive layer 2 is not embedded in the pressure-sensitive adhesive layer 2. An uneven surface is formed by the surface of the pressure-sensitive adhesive layer 2 and the surface of the mesh forming member 3. The size of the mesh 4 is determined by the body size of the pests and beneficial insects to be captured. The mesh 4 is formed larger than the body size of the pest and smaller than the body size of the beneficial insect. In general, the mesh size of the mesh 4 is determined within a range of 5 to 300 mm, depending on the size of pests to be captured and the size of the legally protected birds and beasts that live in the vicinity of beneficial insects and the vicinity.
Further, the mesh forming member 3 is colored in a favorite color of a pest to be captured. For example, when capturing pests of strawberries and eggplants, it is colored blue, and when capturing pests of the number of leafy vegetables, it is colored yellow.
A release paper (not shown) is stuck on the surface of the mesh forming member 3 and the pressure-sensitive adhesive layer 2, and the release paper (not shown) is peeled off immediately before use.

  FIG. 4 is a diagram showing a use state. In FIG. 4, the pest capturing sheet shown in FIGS. 1 to 3 is formed in a cylindrical shape such that the mesh forming member 3 side is the outer surface, and is used by being attached around the pest attracting light 5. By irradiating from the back side of the cylindrical pest capturing sheet 7 by the irradiation light of the pest attracting light 5, the cylindrical pest capturing sheet 7 shines in the color of the mesh forming member 3 as a whole. The insects fly by being attracted by the irradiation light and the color, the pests are attracted to the adhesive layer 2 of the mesh 4, and the beneficial insects are not in contact with the mesh forming member 3 and attracted to the adhesive layer 2.

  In Example 1, the mesh forming member 3 is attached so as to form an uneven surface with the adhesive layer 2, and the mesh 4 is formed larger than the pest body and smaller than the beneficial insect body. Of these, only the pests are captured by adhering the whole body to the adhesive layer 2. By coloring the mesh forming member 3 in blue or yellow according to the type of pests to be captured, there is no need to color the sheet 1 or the pressure-sensitive adhesive layer 2, and the amount of colorant used can be reduced. Further, it is sufficient to produce one kind of sheet with an adhesive, and it is only necessary to select and paste the colored mesh forming member 3 according to the pests to be captured, so there is no waste and the cost can be reduced.

  A second embodiment will be described with reference to FIGS. 5 and 6. The mesh forming member 3 has a mesh 4 formed in a plan view square shape. As shown in FIG. 6, attachment portions are provided at the corners of the rectangular pest capturing sheet 7. An attachment part is attached to the tree 6 that is a path of the capture target animal, and a pest capture sheet 7 is stretched between the trees 6 to capture the capture target pest.

  A third embodiment will be described with reference to FIG. The mesh forming member 3 has a circular mesh 4 and is attached with a sex pheromone attractant that attracts pests, and is colored in a color preferred by the pests to be captured.

  In Examples 1 to 3 described above, the case where the pest capture sheet is formed in a cylindrical shape or a square shape has been described as an example, but all shapes formed corresponding to the installation location and the capture target animal are included in the present invention. included.

  The present invention can also be applied to the purpose of capturing harmful animals such as mice by changing the size of the mesh and attaching the fragrance preferred by the animal to be captured to the mesh forming member.
