Description

  The present invention relates to a killing device that can attract and effectively kill flying insect pests, and in particular, a killing device having a surface coated with an adhesive, and in particular, efficiently kills many whiteflies. It can be related to a killing device.

  Generally, in agricultural, forestry and horticulture, chemical pesticides are often used to control pests. However, when chemical pesticides are used, they may be harmful not only to pests but also to other organisms such as human animals. In recent years, the influence of these chemical agents on human livestock or environmental pollution has been regarded as a problem. In addition, there is a disadvantage that it may adversely affect the health of the worker. Therefore, the use of chemical pesticides has been reduced for the reasons of environmental protection, increased food safety, and increased demand for organic cultivation, and biological control, cultivated control, and comprehensive control by physical control have been implemented. It has come to be.

Among them, in the physical control method, an adhesive trap plate that utilizes the wavelength of the color of light has been frequently used. Among them, whiteflies are difficult-to-control pests, and since they are not effective due to the effects of chemical pesticides and are easily resistant to drugs, yellow attracting adhesive killing tools are used for the purpose of pest control.
The direct damage caused by whiteflies is parasitic on the back of the leaves and sucks the juice. If the growth is poor and the damage is high and the damage proceeds, the flowers and vegetables will die. Silver leaf whiteflies may cause abnormal colored fruits such as mottled fruits such as tomatoes. As an indirect damage, soot disease occurs on the excrement and leaves and fruits turn black. Virus-borne types also emerge, and tomato yellow leaf curl is a major problem.
However, the base material of the adhesive trap plate that uses the wavelength of the color of light is paper, plastic plate, or plastic film, and the installation method is to open a hole in the base material and pass a string or wire, It has been used by hanging on a string or wire stretched around the site by a laundry basket. Such work was troublesome not only for attachment but also for removal of the product after use, such as dirtying hands with an adhesive or attaching it to work clothes.
Therefore, there has been a demand for means that is simple at the time of attachment and detachment and avoids troublesome work.

Patent Document 1 discloses an insect trapping material composed of a pest-killing adhesive sheet and a holding and fixing board. However, in such an insect trapping tool, as long as it works with a fixing board that does not have an adhesive, it can be applied to hands and work clothes. There is no problem of sticking.
However, the part to be attached to a string, wire or the like at the site is the part of the fixed mount, and for that purpose, the mount has to be passed through the string or the like or attached with a laundry basket or the like. Therefore, the work efficiency has not been improved. In addition, such an insect trapping device does not constitute only an adhesive sheet, but requires acquisition of a mount and fixation to the sheet, which requires cost and labor.
In addition, the adhesion to the base material in the manufacturing process is generally applied to the entire surface of the base material, and it is preferable in terms of manufacturing efficiency to provide a margin without an adhesive part in order to improve ease of holding. is not.

Therefore, in Japanese Patent Application No. 2008-037710, the inventors made it easy to attach and detach to a string, wire, etc. stretched around the field such as agriculture by making a cut of a certain shape inside the substrate surface of the substrate body I invented it.
However, it took a long time to remove the short plates and process them one by one. On the other hand, trapping of whiteflies was inefficient with a killing tool with short top and bottom sides.
There is a product called BUG-SCAN (trademark) for large-sized color attracting adhesive plates including the purpose of killing whiteflies. Initially, it was sold in a size of 25cm x 40cm, but the larger the size, the heavier the weight, but on the other hand, the peelability increased in proportion to the area due to the adhesive force, so the workability dropped extremely. Now it has been reduced to 20cm x 40cm.
Japanese Patent Laid-Open No. 11-332446

  An object of the present invention is to provide a killing device capable of killing flying insects such as whiteflies more efficiently.

In order to solve the above-mentioned problem, the present invention is a flying insect pest killing tool having a plate-like base body and an adhesive application portion provided on the base body and applied with an adhesive. Provided is a flying insect trap, characterized in that the substrate has an area of 1200 to 12000 cm ² . If the area of the base material is in the range of 1200 to 12000 cm ² , it is preferable because the sunlight is not blocked or attachment is difficult while maintaining the killing efficiency of the flying pests.
The area is more preferably 1500 to 5000 cm ² .

As the substrate, a film, a sheet, a board, paper or the like is preferably used. As the material, polystyrene, polypropylene, plastic, acrylic, or the like is used. Moreover, papers and non-woven fabrics may be used as long as they meet the required properties.
Examples of the shape of the substrate include a polygon, a circle, and a combination thereof, but a polygon is preferable, and a quadrangle is more preferable.

  The pressure-sensitive adhesive only needs to have an adhesive strength that can capture pests, and various pressure-sensitive adhesives such as acrylic pressure-sensitive adhesives and rubber-based pressure-sensitive adhesives can be used. It is preferable to incorporate a pest attractant in the agent. Alternatively, the base material may be colored with a specific wavelength in order to attract pests. For the purpose of killing whiteflies, it is preferable to use yellow. The pressure-sensitive adhesive may be applied to one side of the substrate, or may be applied to both sides.

It is preferable that a cut is provided inside the surface of the substrate.
By making a cut, you can hang it on and off a hook, such as a string, bar, or wire, without using a special knot or wire. Can be possible.
If the cut is such that the base material can be easily hooked to a hook member such as a string, a rod or a wire stretched around the site by making a cut inside the surface of the base material good. Although depending on the thickness and material of the substrate, the cut can be made with a general cutting tool such as a cutter, a sword, or a scissors. Note that “the cut is provided inside the surface of the base material” means that one end of the cut is provided on the base material surface so as not to reach the outer edge of the base material.

The cut is preferably provided in a curved shape. By making the cut into a curved line, it is easy to hook the killing device on a hook member such as a string, a rod, or a wire, and it is easy to remove. Curved cuts include rectangular and wavy cuts, but arc cuts are more preferred. It is more preferable that the shape is an arc shape of a semi-circle or less and swells in a direction that swells perpendicularly to the ground (the ground side) when used.
In the base material, the cut may be provided in the adhesive application part or may be provided outside the adhesive application part. It is preferable that the cut is provided at a position that is upward when the killing device is hung perpendicularly to the ground. A plurality of cut lines may be provided.

Moreover, it is preferable that the through-hole is provided in the one or both of the edge part of a cut | interruption. By having the through hole, it is difficult to come off when hooked on a string or the like, and the base material can be prevented from being broken from being broken.
The shape of the through hole may be circular, elliptical, triangular, rhombus, quadrangular or more polygonal, star shape, etc., but it is circular due to the durability of the pressure received from the string and the manufacturing work efficiency (mold). It is preferable. In particular, if the circle has a diameter of 2 mm or more, the durability becomes more stable.

The base material preferably has a thickness of 0.1 mm or more. The base material is one in which an adhesive is applied to almost the entire surface, and an operator generally works while holding the side (wall) of the base material. This is because when the substrate thickness is 0.1 mm or more, it is easy to hold and work such as attachment. The substrate thickness is more preferably 0.3 mm or more.
In order to make handling easier, at least one margin (adhesive non-applied portion) may be provided on the outer periphery of the base material.
Moreover, the killing tool of the present invention may be formed by stacking a plurality of base materials each having a pressure-sensitive adhesive applied on one or both sides, and peeling off one by one during use.

The `` flying pest '' to be killed by the killing tool of the present invention is not particularly limited, but widely includes pests that cause damage to various crops, trees, etc. , Thrips, leafhoppers, flies, planthoppers, leafhoppers, snapagas, etc., but whiteflies are more preferred.
The prosthetic device of the present invention can be used in farmland or house. As a method of use, it may be used after planting, but it is effective to use it around a house doorway and window, especially around a skylight and doorway.

In the size of the killing tool, the killing performance of whiteflies and the like can be increased by making the area 1200 to 12000 cm ² large. Moreover, it is hooked in a short time rather than suspending many small killing implements, and the number of hooks decreases and workability | operativity increases.

  Hereinafter, the flying pest killing tool of the present invention will be described more specifically with reference to the drawings. However, the flying pest trap of the present invention is not limited to the following modes.

FIG. 1 shows a plan view of a flying insect trap 1 according to the present invention.
The flying insect killing instrument 1 uses a rectangular flat plate with an area of 1200 to 12000 cm ² as a base material 2, and three arc-shaped cuts 4 swelled downward are provided on the upper part of the base material 2. Both parts are provided with through holes 5.
And the base material 2 is provided with the margin which is not shown in figure, and the adhesive is apply | coated to parts other than a through-hole and the allowance (adhesive application part 3). The operator can prevent the adhesive from getting on the hand by hooking it with a margin.
Such a flying insect killing instrument 1 partially cuts the base material 2 to provide three arc-shaped cuts 4, and further, holes at both ends of the cuts 4 are formed as through holes 5. It can be obtained by applying an adhesive at a predetermined position.

FIG. 2 is a view showing a usage mode of the flying insect pest killing tool 1.
In farmland or a plastic house, the flying insect trap 1 is hooked on the string 6 stretched horizontally with the ground through the cut 4. Flying pests adhere to the adhesive application part 3 and are killed.
After completion of use, the flying insect trap 1 can be removed from the string 6 and discarded.

Hereinafter, more specific description will be given with reference to examples.
In the following examples, a flying insect trap using a base material made of polystyrene was used. An acrylic adhesive was applied to both sides of the substrate.

In the examples, the flying insect pest killing tool 1 (length 58 cm × width 30 cm: area 1740 cm ² ) shown in FIG. 1 was used.
In the comparative example, the flying insect trap 11 (length 10 cm × width 27 cm: area 270 cm ² ) shown in FIG. 2 was used.

1. Flying pest killing tool 1 (n = 2; Examples 1 and 2) and flying pest killing tool 11 (n = 2; Comparative Examples 1 and 2) on the ground in a house where tomatoes are planted It was hung on a wire hung to a height of 1 m at intervals of 5 cm.
After installing for 2 months, the auxiliary weapons were collected, and the number of whitefly kills was measured on both sides of each killing device. The results are shown in Table 1.

From the above results, it was found that the flying insect pest killing tool 1 having a large area has a significantly large number of killing per unit area of whitefly.

2. Comparison of installation time It took about 6 minutes to suspend 18 flying insect pest killing tools 11 (comparative examples) on the cord.
On the other hand, it took 3 minutes to install 3 pieces of large-sized catching devices 1 (Examples) corresponding to 18 flying insect traps 11 (Comparative Example).

Whiteflies are parasitized on the backside of plant shoots and absorb nutrients, so they occur at almost the same height in the house. Therefore, an adhesive plate having a large area is more effective than installing with a gap. Also, the longer one in the vertical direction eliminates the escape.
For that purpose, stripping and installation of the plate in the installation were problems, but it was made possible by making the adhesive easy to remove and making a cut in the substrate.
