Description

The present invention relates to an insect capturing tool for capturing and investigating a pest, and an attaching method of the insect capturing tool, which are attached to the outer periphery of a trunk where pests such as the Platypus quercivorus occur or inhabit.

Conventionally, insect trapping sheets using an adhesive sheet wrapped around a tree trunk as an insect capturing tool for capturing and extinguishing pests from a tree where pests are generated or inhabited, or for investigation (for example, Patent Document 1, 2) is known.
Such a sheet for catching insects includes a plurality of sheets disposed between a pressure-sensitive adhesive sheet having a pressure-sensitive adhesive surface on one side or both sides of the flexible sheet and a bark opposed to the pressure-sensitive adhesive surface of the pressure-sensitive adhesive sheet. It consists of a combination with a spacer. The spacer enhances the insect trapping efficiency by forming a gap through which the insect can enter between the adhesive surface of the adhesive sheet and the bark.

  Therefore, wrap an adhesive sheet with multiple spacers attached to the adhesive surface in advance at the required interval around the outer circumference of the trunk, or attach an adhesive sheet after attaching multiple spacers coated with adhesive on one or both sides to the outer circumference of the trunk In other words, it is configured to secure a space for capturing pests.

By the way, damage by oak beetles is a problem in oaks such as Mizunara, Quercus, Ubamegashi, and Arakashi, and mushrooms such as Sudajii and Tsuburajii. This damage is thought to be caused by the occurrence of a mold by the female of the beetle, the mold, which has propagated in a mine tunnel perforated by the male of the beetle.
The oak beetle pierces a tree trunk with a population of several hundred at most, and lays hundreds of eggs when it is large with one female. For this reason, a large amount of froth (wood waste and funnel) is generated from the penetration hole of the trunk bored by the oak beetle.

However, in the insect catching sheet that combines the above-mentioned conventional adhesive sheet and spacer, when catching insects that generate a large amount of flares, such as an oak beetle, a large amount of the flaming is on the spacer. As a result, there was a problem that it was caught on the adhesive surface of the adhesive sheet and could not be captured sufficiently.
Therefore, if the spacers are made small so that it is difficult for the flax coming out from the hole in the trunk to be accumulated, it becomes difficult to maintain an appropriate interval, or more spacers are placed between the adhesive sheet and the bark. Therefore, the installation work becomes complicated.

Therefore, the present invention has been made in view of such a situation, and it is easy to attach to a tree trunk, and a good insect catcher and insect catcher attachment that does not reduce the insect capture efficiency due to the flass. It aims to provide a method .

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, the insect trap 1 according to the first embodiment of the present invention includes a pest capture survey sheet 3 and a knotted net 2 that are flexible sheets.
The knotted net 2 according to the first embodiment is a net formed by tying a thread 21 having a wire diameter of about 1 mm, which is a flexible long member, and a knot 23 being a knot has a diameter of about 3 mm. ing. The knotted net 2 shown in FIG. 1 is a square mesh with a square mesh, but a rhombus with a rhombus may be used. The thread | yarn 21 consists of synthetic fibers, such as polyethylene, for example.

  Each nodule 23 in the nodule net 2 is arranged between the bark 41 opposite to the adhesive surface 31 of the pest capture survey sheet 3 when the pest capture survey sheet 3 to be described later is fixed to the trunk 40, A spacer that forms a gap S suitable for capturing is formed (see FIG. 6). Therefore, the diameter of each nodule 23 is preferably in the range of 1 to 10 mm that forms a gap S from the extent that insects (beetles of 4 to 5 mm in body length such as oak beetle) can pass through to the extent that the wings can be expanded. The diameter of the knot 23 can be easily adjusted by changing the wire diameter of the yarn 21 or the shape of the knot.

The pest capture survey sheet 3 is a rectangular flexible sheet material made of paper, cloth, non-woven fabric, synthetic resin film, biodegradable plastic or the like having water resistance and moisture resistance outdoors. Paper is preferable in terms of good productivity and reduction of the burden at the time of disposal. In that case, a laminate made of polyethylene, polypropylene, PET (polyethylene terephthalate) or the like to increase the strength is preferable.
On the outer surface 3a of the pest capture survey sheet 3, as shown in FIG. 1, an entry field 33 for entering the installation status, installer, sample number, etc., and a tucker when fixing the pest capture survey sheet 3 to the trunk A fixed position mark 35 is displayed to indicate the position at which the staple (needle) is struck by (striking machine). In order to notify third parties, usage indications such as “Squirrel Survey Sheet” and “Do not remove during investigation” can also be provided.

On the inner surface 3b of the pest capture investigation sheet 3, as shown in FIG. 2, an adhesive surface (part indicated by slanted lines in FIG. 2) 31 to which an adhesive is applied except for a predetermined range from the outer edge portion is formed. . As the pressure-sensitive adhesive, it is preferable to use an adhesive that allows insects to adhere only by contact without applying pressure, and can maintain the pressure-sensitive property for a long period of 3 months or longer even when used outdoors. The thickness of the layer coated with the adhesive is preferably 50 to 400 μm. If the thickness of the layer to which the adhesive is applied is too thin, sufficient capture efficacy and sustainability cannot be obtained, and if it is too thick, the adhesive will sag, it will be difficult to wrap around the trunk, and the cost will increase. There's a problem.
In addition, when the pest capture survey sheet 3 is made of paper, the adhesive may be gradually absorbed by the paper and decrease from the surface. In that case, if the laminated surface of the laminated paper is used as an adhesive surface, absorption of the adhesive into the paper can be prevented and the adhesiveness can be maintained.

In the lower layer of the adhesive surface 31, there are provided 20 cells 36 having a scale around the periphery, and a plurality of marks 37 indicating an attachment position and an attachment direction when attaching a spacer 60 described later. By providing the grids 36 below the adhesive surface 31, the number of insects captured can be measured for each grid. The pressure-sensitive adhesive is preferably a transparent or translucent adhesive so that the lower cell 36 can be seen.
In the center of the upper edge of the inner surface 3b, there is an orientation mark (for example, “east” or “valley”) 32 indicating the direction and the slope direction in order to unify the installation orientation when fixing the pest capture survey sheet 3 to the trunk. Is provided. Further, an entry field 33 and a fixed position mark 35 are displayed around the adhesive surface 31 in the same manner as the outer surface 3a.

  In addition, as shown in FIG. 3, the release paper 39 is stuck on the adhesion surface 31 of the pest capture investigation sheet 3 before use so that undesired adhesion may not occur when being sold and transported. . And when using the pest capture investigation sheet | seat 3, the release paper 39 is peeled off, breaking the perforation 38 formed in the longitudinal direction center, and the adhesive surface 31 is exposed. Here, by peeling off the release paper 39 while being divided into two at the perforation 38, the force required to peel off the release paper 39 can be made smaller than when the force is not divided. In order to make it easy to peel off the release paper 39, the adhesive surface 31 is not formed at the longitudinal center of the inner surface 3b corresponding to the perforation 38.

Next, a method for using the insect trap 1 according to the first embodiment will be described. The insect trap 1 is used by being attached to the bark 41 of the trunk 40 at an appropriate height (for example, 1 m to 4 m) from the ground surface.
First, as shown in FIG. 4, the knot network 2 is wound around a predetermined position of the trunk 40 and fixed so that the knot 23 contacts the bark 41. The knotted net 2 formed by tying the yarn 21 has flexibility, so that it can be easily wound along the bark 41 of the trunk 40 and can be easily fixed to the trunk 40. As a fixing means for the knotted net 2, various fixing means such as a fastener, a fastening band, and a tucker can be used.

  Next, after the release paper 39 is peeled off, as shown in FIG. 5, the pest capture investigation sheet 3 is wound around the trunk 40 from above the barbed net 2 so that the adhesive surface 31 of the inner surface 3 b faces the bark 41. At this time, the pest capture survey sheet 3 is wound so that the orientation mark 32 provided on the inner surface 3b is on the direction of installation, for example, “east” or on the “valley” side of the slope.

  Then, the attachment of the insect capturing tool 1 is completed by hitting the staple 45 with the tacker to the fixed position mark 35 displayed on the outer surface 3a and fixing the pest capturing investigation sheet 3 to the trunk 40. Since the pest capture survey sheet 3 made of a flexible sheet material is flexible, it can be easily wound along the bark 41 and the knotted net 2 of the trunk 40 and can be easily fixed to the trunk 40. It is.

  In this way, the insect trap 1 fixed to the tree trunk 40 is attached to the nodule 23 of the nodule net 2 with the adhesive surface 31 of the pest capture survey sheet 3 wound from above the nodule net 2. As shown in FIG. 6, gaps S suitable for catching insects are formed between the adhesive surface 31 and the bark 41, as shown in FIG. 6.

If the insect trap 1 fixed to the trunk 40 is left as described above, pests such as Platypus quercivorus that have come out of the bore hole of the trunk 40 adhere to the adhesive surface 31 of the pest capture survey sheet 3, Be captured. In addition, pests that enter between the adhesive surface 31 and the bark 41 in an attempt to pass through the gap S are attached to the adhesive surface 31 and captured.
In this way, the insect trap 1 that has been fixed and left on the trunk 40 for an appropriate period (usually several months) can be removed from the insect capture survey sheet 3 at an appropriate time to observe the captured insects or Surveys are conducted by measuring the number of captures every time.
As a specific example in the Platypus quercivorus, the period when the Platypus quercivorus escapes from the trunk spans about half a year from June to November in Honshu, so the pest capture survey sheet was set up around May, It is preferable to collect around November.

  As described above, according to the insect trap 1 according to the first embodiment, the adhesive surface 31 faces the bark 41 after the knotted net 2 having the knot 23 having a predetermined size is wound around the trunk 40. By simply wrapping the pest capture survey sheet 3 on the trunk 40 from above the knotted net 2, a gap S suitable for capturing insects between the adhesive surface 31 and the bark 41 of the pest capture survey sheet 3 can be easily obtained. Can be formed. Therefore, the attachment work to the trunk 40 is simplified, and the insect trap 1 can be easily attached to many trunks 40.

Further, since the thread 21 constituting the knot network 2 itself is thin and the knot 23 is also small, it is difficult to pile a large amount of flax from the hole of the trunk bored by an insect such as an oak beetle. And Fras falls to the ground. Therefore, the sticky surface 31 effective for catching is not reduced by the fluff accumulated on the knotted net 2, and the insect catching tool 1 is less likely to lower the insect catching efficiency.
Further, the interval between the nodules 23 and the nodules 23 and the size of the nodules 23 can be arbitrarily changed by changing the size of the nets of the nodular net 2 and the shape of the knots. Therefore, the thickness of the trunk 40 and the shape of the bark 41 Adjustment according to the above is easy, and the installation work of the insect trap 1 is not complicated.

7 and 8 are perspective views showing a usage state of the spacer and the insect trapping tool according to the second embodiment of the present invention. In addition, about the structural member similar to the insect trap 1 which concerns on the said 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.
The insect trap 11 according to the second embodiment includes a pest capture survey sheet 3 that is a flexible sheet and a flexible long member 12.
The flexible long member 12 according to the second embodiment is a string in which a plurality of knots 17 are formed at predetermined intervals on a thread 15 having a wire diameter of about 1 mm, and the knots 17 have a diameter of about 3 mm. . The thread | yarn 15 consists of synthetic fibers, such as polyethylene, for example.

  Each knot 17 in the flexible long member 12 is disposed between the bark 41 opposite to the adhesive surface 31 of the pest capture survey sheet 3 when the pest capture survey sheet 3 is fixed to the tree trunk 40. The spacer which forms the clearance gap S suitable for catching is comprised. Therefore, the diameter of each knot 17 is preferably in the range of 1 to 10 mm that forms a gap S from the extent that insects (beetles such as 4 to 5 mm in length) can spread the wings. The diameter of the knot 17 can be easily adjusted by changing the wire diameter of the thread 15 or the shape of the knot.

Next, a method of using the insect trap 11 according to the second embodiment will be described.
First, as shown in FIG. 7, the flexible elongate member 12 is spirally wound at a predetermined pitch P around a predetermined position of the tree trunk 40 and fixed so that the knot 17 contacts the bark 41. Since the flexible long member 12 made of the thread 15 has flexibility, it can be easily wound along the bark 41 of the trunk 40 and can be easily fixed to the trunk 40. As a fixing means of the flexible long member 12, various fixing means such as a fastener, a fastening band, and a tucker can be used, and both end portions may be connected to each other.

Next, in the same manner as the insect trap 1 according to the first embodiment, after removing the release paper 39, the insect pest capture investigation is performed so that the adhesive surface 31 of the inner surface 3b faces the bark 41 as shown in FIG. The sheet 3 is wound around the trunk 40 from above the flexible long member 12.
Then, the attachment of the insect capturing tool 11 is completed by hitting the staple 45 with the tacker to the fixed position mark 35 displayed on the outer surface 3a and fixing the pest capturing investigation sheet 3 to the trunk 40.

  In this way, the insect trap 11 fixed to the trunk 40 has the adhesive surface 31 of the pest capture survey sheet 3 wound around the flexible long member 12 attached to the knot 17 of the flexible long member 12. In addition, gaps S suitable for capturing insects are formed between the adhesive surface 31 and the bark 41 at intervals between the plurality of knots 17.

As described above, according to the insect trap 11 according to the second embodiment, the flexible long member 12 having the plurality of knots 17 formed at predetermined intervals is spirally formed on the trunk 40 at the predetermined pitch P. After winding, the adhesive surface 31 and the bark 41 of the insect capture survey sheet 3 are simply wound around the trunk 40 from above the flexible long member 12 so that the adhesive surface 31 faces the bark 41. A gap S suitable for catching insects can be easily formed between the two. Therefore, the attachment work to the trunk 40 is simplified, and the insect trap 11 can be easily attached to many trunks 40.

  Further, the thread 15 itself of the flexible long member 12 is thin and the knot 17 is small, so that it is difficult to pile a large amount of the brass from the hole of the trunk bored by an insect such as an oak beetle. And the flas falls to the ground. Therefore, the sticking surface 31 effective for catching is not reduced by the hull accumulated on the flexible long member 12, and the insect catching tool 11 is less likely to lower the insect catching efficiency.

The size of the knot 17 and the interval between the knot 17 and the knot 17 may be changed by changing the interval of the knot 17 and the way of knotting, or changing the pitch P when the flexible long member 12 is wound around the trunk 40 in a spiral shape. Therefore, the adjustment according to the thickness of the tree trunk 40 and the shape of the bark 41 is easy, and the installation work of the insect catcher 11 is not complicated.

  FIG. 9 is a partial perspective view of a spacer according to the third embodiment of the present invention. The insect trap according to the third embodiment is configured by using the flexible long member 50 as a spacer instead of the flexible long member 12 according to the second embodiment.

  As shown in FIG. 9, the flexible long member 50 according to the third embodiment includes a plurality of pieces connected at predetermined intervals by a thread 51 having a wire diameter of about 1 mm thinner than the gap S suitable for catching insects. The spacer member 52 is used. The thread 51 is made of synthetic fiber such as polyethylene, and the spacer member 52 is made of synthetic resin such as foamed polyethylene.

  The spacer member 52 in the flexible long member 50 is a triangular prism having a triangular outer shape partly having an acute triangular portion in plan view, and the pest capture survey sheet 3 is fixed to the trunk 40. Sometimes, it is arranged between the adhesive surface 31 of the pest capture survey sheet 3 and the opposing bark 41 to form a spacer that forms a gap S suitable for capturing insects. Therefore, the thickness of each spacer member 52 (the height of the triangular prism) is 1 to 10 mm which forms a gap S from which an insect (4 to 5 mm long beetle such as an oak beetle) can pass through to which the wings can be spread. A range is preferred. Further, as shown in FIG. 9, these spacer members 52 are connected by a thread 51 so that an acute-angled triangular portion (top) 52 a in a plan view is in the same direction (upward in the drawing).

Therefore, after the flexible long member 50 is wound around the tree trunk 40 in a spiral manner at a predetermined pitch so that the acute-angled triangular portions 52a of the plurality of spacer members 52 face upward, the adhesive surface 31 is relative to the bark 41. Thus, it is suitable for capturing insects between the adhesive surface 31 and the bark 41 of the pest capture survey sheet 3 simply by wrapping the pest capture survey sheet 3 on the trunk 40 from above the flexible long member 50. The gap S can be easily formed.
As a result, the same effect as the insect trap 11 according to the second embodiment can be obtained.

  In addition, the thread 51 itself of the flexible long member 50 is thin, and it is attached so that the acute triangular portion 52a of the spacer member 52 becomes the top surface. It is possible to make it difficult to stack a large amount of the brass coming out of the entrance hole on the spacer member 52, and the glass slides on the inclined surface of the spacer member 52 and falls to the ground. Therefore, the adhesive surface 31 effective for catching is not reduced by the hull piled on the flexible long member 50, and the insect catching efficiency according to the third embodiment is not easily lowered.

  In addition, since the spacer member 52 is connected to the thread 51 in advance, even if the size per one is reduced and the number thereof is increased, the attaching operation of the insect trapping tool does not become complicated. Therefore, it is possible to make the spacer member small and make it difficult to accumulate the flash regardless of the outer shape.

FIG. 10 is a partially broken perspective view showing a usage state of the insect trapping tool according to the fourth embodiment of the present invention. In addition, about the structural member similar to the insect trap 1 which concerns on the said 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.
The insect trap 61 according to the fourth embodiment includes the pest capture survey sheet 3 and the spacer 60.

  The spacer 60 according to the fourth embodiment is a triangular prism having a triangular outer shape, at least a part of which has an acute triangular portion 60a in plan view, and when the pest capture survey sheet 3 is fixed to the trunk 40. The gap S suitable for catching insects is formed on the adhesive surface 31 of the pest catching survey sheet 3 in advance. Therefore, the thickness of each spacer 60 (the height of the triangular prism) is in the range of 1 to 10 mm that forms a gap S from which an insect (4-5 mm long beetle such as an oak beetle) can pass through to the extent that the wings can be expanded. Is preferred. The spacer 60 is made of a synthetic resin such as foamed polyethylene.

  As shown in FIG. 11, the spacer 60 is attached to the adhesive surface 31 so that the acute-angled triangular portion 60 a in a plan view becomes a top surface when the pest capture survey sheet 3 is wound around the trunk 40, thereby It is possible to make it difficult to stack a large amount of the brass 71 from the penetration hole 70 of the trunk 40 pierced by insects such as a beetle on the spacer 60, and the brass 71 slides on the inclined surface of the spacer 60 and falls to the ground. Therefore, the sticky surface 31 effective for capturing is not reduced by the frass 71 stacked on the spacer 60, and the insect trapping tool 61 according to the fourth embodiment is also difficult to reduce the insect trapping efficiency.

  Therefore, a large amount of the brass 71 from the trunk hole 70 bored by a bug such as a longhorn beetle is difficult to accumulate on the spacer 60. That is, since it is not necessary to reduce the number of spacers 60 per piece and increase the quantity, the attaching operation of the insect trap 61 does not become complicated. Further, as shown in FIG. 2, the adhesive surface 31 is provided with a mark 37 indicating the mounting position and mounting direction when the spacer 60 is mounted. The spacer 60 can be securely attached so that

  Therefore, the adhesive surface of the pest capture survey sheet 3 is simply wound around the trunk 40 with the pest capture survey sheet 3 in which a plurality of spacers 60 are attached in advance so that the acute-angled triangular portion 60a becomes the top surface of the adhesive surface 31. A gap S suitable for capturing insects can be easily formed between 31 and the bark 41. As a result, the same effect as the insect trap 1 according to the first embodiment can be obtained.

In addition, the shape of the spacer according to the fourth embodiment is not limited to the shape of the spacer 60 as long as it is an outer shape in which at least a flat portion 71 having an acute-angled triangular portion is difficult to stack in plan view, Various outer shapes can be used.

The long spacer member 24 is a round bar-like member having rigidity made of, for example, synthetic resin or metal. The long spacer member 24 is installed in a substantially vertical direction with a predetermined interval between the bark 41 and the bark 41 by piercing the lower end into the ground. Of course, the cross-sectional shape of the long spacer member 24 is not limited to a circular shape, and various cross-sectional shapes such as an elliptical shape and a polygonal shape can be adopted. Further, the long spacer member 24 may have an outer shape having nodes at predetermined intervals along the longitudinal direction.

  These long spacer members 24 are arranged between the adhesive surface 31 of the pest capture survey sheet 3 and the opposite bark 41 when the pest capture survey sheet 3 is fixed to the trunk 40, and capture the insects. A gap S is formed in a range of 1 to 10 mm suitable for the above (see FIG. 14). The distance between the adhesive surface 31 and the bark 41 can be easily adjusted by changing the diameter and number of the long spacer members 24.

Next, a method for using the insect trap 81 according to the fifth embodiment will be described.
First, the long spacer members 24 are arranged around the trunk 40 at predetermined intervals so that the lower ends are pierced into the ground and the upper end 24a is directed in a substantially vertical direction with a predetermined interval between the bark 41 and the bark 41. . The long spacer member 24 made of a rigid round bar can be easily pierced into the ground around the trunk 40 and can be easily fixed to the trunk 40. As a fixing means for the long spacer member 24, a string that is directly tied to each long spacer member 24 or a through-hole formed in the diameter direction (short direction) of each long spacer member 24 is inserted. Various fixing means such as wrapping around the trunk 40 can be used.

Next, like the insect trap 1 according to the first embodiment, after the release paper 39 is peeled off, the adhesive surface 31 of the inner surface 3b faces the bark 41 as shown in FIG. The pest capture investigation sheet 3 is wound around the trunk 40 from above the long spacer member 24 so that the upper end 24a of the member 24 is exposed.
