Things. Hereinafter, the present invention will be described in detail with reference to embodiments.

[0010]

FIG. 1 shows an insect trap according to the present invention. The trap is made of a plastic base substrate 1 placed on a floor of a clean room or the like, and is provided with a lattice pattern 4 at an appropriate interval on at least one surface side.
Further, an adhesive layer 2 for insect trapping is provided on the upper surface of the substrate 1. Although not always necessary, the base substrate provided with the pressure-sensitive adhesive layer may be
It is also possible to protect by providing.

Here, the plastic forming the base substrate 1 or the housing 3 is not particularly limited, but may be any transparent plastic known as a substantially dust-free material. The generation of dust and the like can be further suppressed by selecting a plastic material that does not easily carry static electricity. It is also possible to select a plastic material that is light and hardly generates harmful substances during incineration. Further, it is preferable to select one that is resistant to water wetting. Specific examples include polyethylene, polypropylene, polystyrene, polyester, and polyamide. In the present invention, it is preferable to use polyester, and particularly preferable to use polyethylene terephthalate (PET) or a similar derivative thereof. There is no particular limitation on the size and thickness of the base, and it is easy to appropriately select according to the purpose of use, that is, the type, number, period of use, place of use, and the like of the captive insects. In a clean room, usually, small insects are often used, and the number of the insects is usually very small. Therefore, since they are used for a long time, the size of the substrate is a square having a size of about 5 to 20 cm. Preferably, there is. The thickness of the base is preferably about 0.5 to 2 mm. The base substrate 1 and the housing 3 may be separately molded and assembled, or may be integrally molded from one plastic plate. There is no particular limitation on such a molding method,
Ordinarily known molding methods and molding apparatuses can be used.

The pressure-sensitive adhesive that can be used in the present invention is not particularly limited, and is a pressure-sensitive adhesive used in a pressure-sensitive adhesive trap of generally known small insects and the like (including insects of a size similar to a beetle) and is transparent. If it is, it can be used. Further, it is preferable to maintain the adhesiveness even when wet with water or irradiated with ultraviolet rays. Further, it is preferable to use a solvent which hardly evaporates the solvent. Specifically, natural rubber, a rubber-based adhesive obtained by adding a tackifier such as rosin to a rubber such as a butadiene-styrene copolymer, or an acrylic monomer such as butyl acrylate alone or a copolymer as a main component And the like. The thickness of the pressure-sensitive adhesive layer is also not particularly limited, and it is easy to appropriately select according to the type, number, period of use, place of use, and the like of the captive insects. The method and apparatus for providing the pressure-sensitive adhesive layer 2 on the base substrate 1 are not particularly limited, and a method and an apparatus generally used in such a field can be used.

The base substrate 1 is provided with a measuring grid line 4 for easily and easily measuring the number of insects captured by the adhesive layer 2, and the line width of the grid line,
There are no particular restrictions on the colors and patterns. It is easy to determine the grid spacing so that measurement can be performed most easily according to the type, size, and number of insects to be captured. In a clean room, small insects are usually captured in a very small amount, and in such a case, the lattice is preferably about 0.5 cm to 2 cm. Further, the pattern may have another shape. The method of forming the grid lines 4 is not particularly limited, and it is easy to provide the grid lines 4 on the base substrate by printing or the like.

The housing 3 for protecting the base substrate 1 and the pressure-sensitive adhesive layer 2 is not particularly limited, and a housing having a size and shape used in a generally known pressure-sensitive adhesive trap for small insects or the like can be applied. In particular,
Examples include a shape that is protected by covering with a triangular roof shape, and a shape that is covered with a square box shape. It is easy to appropriately select a preferable shape in consideration of the properties of the captive insects, the period of use, and the like. In the housing of the present invention, it is particularly preferable that the shape be a triangle. This is because of material savings, strength and ease of neglect. Further, a part of the housing 3 is transparent so that the insect trapped on the adhesive layer and the lattice of the base substrate under the adhesive layer can be visually recognized from the outside. There is no particular limitation on such a transparent part, and it is easy to provide a transparent part of an appropriate size depending on the size, number, etc. of the insects.

FIG. 1 also shows a plastic release liner 5 provided on the pressure-sensitive adhesive layer of the insect trap according to the present invention so as to be removed when used. There is no particular limitation on the release liner used for this purpose, and any known release liner for a pressure-sensitive adhesive may be used. It is preferably a material that does not generate dust and is hardly charged with static electricity and hardly emits harmful substances when incinerated. Specifically, a silicon-based liner is particularly preferable. Without peeling off the release liner, the housing can be stored in an expanded state (not shown).

FIG. 2 shows an example of measuring the number of insects 6 captured by the adhesive layer 2. That is, since at least a part of the base substrate 1 and the adhesive layer 2 of the insect trap according to the present invention is transparent, the presence or absence or the number of the captured insects 6 can be easily recognized and measured. That is,
When observed from the back side of the substrate (FIG. 2A), the grid 4 of the substrate and the insects 6 captured through the adhesive 2 can be easily visually recognized at the same time, and can be easily measured. Further, in some cases, more detailed observation can be performed using a measuring machine, a microscope, or the like. In addition, the side where the insect was captured (the side of the housing)
2 (b), the grid 4 can be easily recognized because the pressure-sensitive adhesive layer 2 is transparent.

FIG. 3 shows a preferred embodiment of the trap according to the present invention. The housing 3 has a triangular roof shape and has a shape with a hole 7. Although not shown in the drawings, the housing can be unfolded into a flat plate shape before use, and in this case, the housing can be stored in an overlapping manner, which is preferable. In use, it can be easily bent. Furthermore, in order to fix the respective ends of the housing and maintain the roof shape when forming the triangular shape, it is possible to form the housing ends into an appropriate shape and hold them together. Various information (company name, characters such as "under investigation") can be printed on the housing as needed.
