Description

The present invention relates to a suspended assembly type insect trap used for capturing insects.

  This type of insect trap is disclosed, for example, in Patent Document 1 below. The insect trap of Patent Document 1 includes a trap cage, which is formed by folding a single paper blank. The housing secures a space inside thereof, and the space is opened through openings formed on both side surfaces of the housing. Therefore, pests can enter the space through the opening of the enclosure. On the other hand, an adhesive sheet is bonded in advance to the inner surface that divides the space, that is, the inner surface of the blank, and a pest attractant is adhered to the adhesive surface of the adhesive sheet.

  The pest attractant releases an effective component for attracting the pest and promotes the invasion of the pest into the space. Pests that enter the space stick to the adhesive surface of the adhesive sheet and are captured on the adhesive sheet. Thereafter, the pest type and the number of captured pests are verified for the captured pests. Such verification is useful for quickly grasping the state of occurrence of pests in the environment where the insect trap is installed.

  If the environment in which the insect trap is installed is clear, there is no adverse effect on the adhesiveness of the adhesive sheet that captures insects. However, when the insect trap is installed in an inferior environment where the concentration of dust is high, the adhesiveness of the adhesive sheet decreases rapidly. That is, dust is likely to adhere to the pressure-sensitive adhesive surface of the pressure-sensitive adhesive sheet under the above-mentioned adverse environment, and the adhered dust significantly reduces the pressure-sensitive adhesive property of the pressure-sensitive adhesive sheet. As a result, the adhesiveness of the adhesive sheet is not maintained for a long time. In this regard, if we try to physically prevent the invasion of dust into the insect trap, the invasion of the pest itself into the insect trap is also suppressed, and the efficiency of the insect trap to capture the pest, There is concern about a decrease in insect trapping efficiency.

The object of the present invention is a suspended assembly type that can maintain the performance of the pressure-sensitive adhesive sheet that captures pests, that is, the pressure-sensitive adhesiveness of the pressure-sensitive adhesive sheet over a long period of time even when installed in an environment where the dust concentration is high. It is to provide an insect trap.

The above-described object is achieved by the suspended assembly type insect trap of the present invention, and the assembly type insect trap has a back plate and a front plate each having a substantially rectangular shape. One end is a plate-shaped blank with a fold line, and the back plate and the front plate can be folded along the fold line so as to overlap each other,
Leaving the side edges along the front Sulfur butterfly longitudinal direction on the inner surface of the blank, respectively, a pressure-sensitive adhesive sheet bonded over the front plate from the back plate, the pests can capture an adhesive surface and the adhesive surface An adhesive sheet having a film-like release material to cover;
Provided respectively at the other ends of the back plate and the front plate, and when the front plate is folded, the front plate is bent in an arc shape from the side between the back plate and the front plate. A pair of engagement elements that secures a space that allows intrusion of pests of the two, and that allows the other end portions to be separated from each other in this state, while allowing the back plate and the front plate to be suspended. ,
Provided at the both side edges of one of the back plate and the front plate, and the both side edges are partially foldable along the adhesive sheet toward the other of the back plate and the front plate and folded. And at least a pair of flaps that sometimes face each other.
Preferably, the back plate and the front plate of the blank have side edges extending straight along the longitudinal direction, and each flap is formed on one side edge of the back plate and the front plate. Each of them is defined by two cut lines that are formed from a part and are spaced apart from each other in the longitudinal direction, and a folding line that connects the inner ends of these cut lines and extends in the longitudinal direction.

When the insect trap is installed in a dusty environment, the present inventor has found an unexpected effect that the trapping efficiency is not significantly reduced if dust intrusion is suppressed by a pair of flaps.
Specifically, according to the assembly type insect trap described above, the pair of flaps are provided on both side edges of the back plate or the front plate, and when the insect trap is installed in a dusty environment, the pair of flaps is Folded and stands up against back plate or front plate. The flaps standing up in this way effectively function as a screen to protect the adhesive surface of the adhesive sheet from dust without hindering the invasion of pests into the space, thereby reducing the adhesion of dust to the adhesive surface. .
Other objects and preferred embodiments of the present invention will become apparent from the following description with reference to the accompanying drawings.

Even in a dusty environment, the suspended assembly-type insect trap of the present invention can reduce dust adhering to the adhesive surface of the adhesive sheet by the action of a pair of flaps, thus maintaining the adhesiveness of the adhesive sheet for a long time As a result, pest capture performance can be effectively demonstrated.

It is a top view of the insect trap before the assembly which concerns on one Embodiment of this invention. It is an expanded view of the blank which forms the insect trap of FIG. It is sectional drawing of the adhesive sheet of FIG. It is a figure which shows a part of folding flap of FIG. It is a perspective view which shows the insect trap after completion of an assembly. It is the figure which looked at the upper part of the insect trap of FIG. 5 from the back surface. It is a schematic side view of the insect trap of the aspect 0. It is a schematic side view of the insect trap of aspect 1. It is a schematic side view of the insect trap of aspect 2. It is a schematic side view of the insect trap of aspect 3. It is the schematic of the exposure test apparatus which exposes an insect trap in the environment with much dust. It is the schematic of the insect trapping test apparatus which verifies the trapping function of the insect trap exposed to the environment with much dust.

Referring to FIG. 1, a suspended assembly type insect trap (hereinafter simply referred to as an insect trap) according to an embodiment of the present invention is shown in a state before assembly.
The insect trap before assembly includes a single paper blank 10 which is folded in two. As development view of a blank 10 is shown in Figure 2, the blank 10 is an elongated plate shape, having a substantially rectangular back plate 12, the same Ku rectangle and a front plate 14. As seen in FIG. 1, the lower ends (one ends) of the back plate 12 and the front plate 14 are connected to each other via a folding line 16. Therefore, the front plate 14 can be folded along the folding line 16 toward the back plate 12, and when the insect trap is in a state before assembly, the front plate 14 is attached to the back plate 12 as shown in FIG. It is superimposed.

As shown in FIG. 2, when the lengths along the longitudinal direction of the back plate 12 and the front plate 14 are represented by Lr and Lf, respectively, the length Lf of the front plate 14 is larger than the length Lr of the back plate 12. It is long by a predetermined length. Therefore, as shown in FIG. 1, when the front plate 14 is superimposed on the back plate 12, the upper end (the other end) of the front plate 14 protrudes from the upper end (the other end) of the back plate 12.
Furthermore, although the back plate 12 has a constant width Wr over the entire region in the longitudinal direction, the width of the front plate 14 is not constant. Specifically, the upper end portion of the front plate 14 has the same width as the width Wr of the back plate 12, but the portion between the upper end portion and the lower end portion of the front plate 14 has a width Wf. It is wider than Wr by a predetermined width. Further, the width of the lower end portion of the front plate 14 is gradually reduced from Wf to Wr.
Referring to FIG. 2 again, a long adhesive sheet 18 is bonded to the inner surface of the blank 10 in advance. The adhesive sheet 18 extends from the upper end portion of the back plate 12 to the upper end portion of the front plate 14 beyond the folding line 16.

Specifically, the adhesive sheet 18 is affixed to the entire area of the inner surface of the blank 10 except for the outer peripheral edge of the blank 10. Therefore, both the back plate 12 and the front plate 14 have both side edge portions and upper end portions exposed from the adhesive sheet 18.
The pressure-sensitive adhesive sheet 18 is in the form of a double-coated adhesive tape, and has an adhesive surface that is bonded to the inner surface of the blank 10 and an exposed pressure-sensitive adhesive surface 20. When the insect trap is in a state prior to assembly, the adhesive surface 20 is covered with a film-like release material 22 as shown in FIG.

Furthermore, for example, two attachment positions of the pest attractant are defined on the adhesive surface 20, and these attachment positions are indicated by reference numerals 24 _U and 24 _L in FIG. The pasting positions 24 _U and 24 _L are both positioned on the back plate 12, and a predetermined distance is secured between the pasting positions 24 _U and 24 _L along the longitudinal direction of the back plate 12. Center of the back plate 12 as viewed in the longitudinal direction of the back plate 12, for example, is defined between the application position 24 _U, 24 _L.

In the case of this embodiment, the pasting positions 24 _U and 24 _L are represented by marks, and these marks are printed on the inner surface or the adhesive surface 20 of the blank 10.
At the attachment positions 24 _U and 24 _L , either a sex pheromone inducer or a diet inducer is attached. The sex pheromone inducer contains the pest sex pheromone to be captured, and the diet attractant contains the pest diet component.

  On the other hand, a cut line 26 is formed at the upper end portion of the back plate 12 exposed from the adhesive sheet 18. The cut line 26 is positioned in the center when viewed in the width direction of the back plate 12 and forms a U-shape that opens toward the upper end of the back plate 12. Such a score line 26 forms an engagement tab 28 at the upper end of the back plate 12. The engagement tab 28 can be lifted from the inner surface of the back plate 12, and the raised engagement tab 28 forms one engagement element of a pair of engagement elements described later.

Further, both ends 26e of the cut line 26 are folded back toward the outside of the engagement tab 28, and form a U-shape opposite to the U-shape of the engagement tab 28. When the engagement tab 28 is lifted, both ends 26e form arcuate corners on both sides of the base of the engagement tab 28.
Further, in the present embodiment, a through hole 30 is formed in the center of the engagement tab 28. The through hole 30 enables the blank 10, that is, the back plate 12 to be suspended.
On the other hand, an engagement notch 32 is formed at the upper end of the front plate 14, and this engagement notch 32 is disposed at the center in the width direction of the front plate 14. The engagement notch 32 forms the other engagement element. In the present embodiment, the engagement notch 32 includes a U-shaped portion 32 _U and V-shaped portions 32 _V adjacent to both sides of the U-shaped portion 32 _U. These V-shaped portions 32 _V are formed on the front plate 14. It is connected smoothly to the upper end.

Here, the distance D between the bottom of the V-shaped portion 32 _V and the folding line 16 coincides with the length Lr of the back plate 12. The U-shaped portion 32 _U has the same width as the diameter of the through hole 30 and can match the through hole 30.
Further, the front plate 14 has a fold line 34. The fold line 34 is disposed between the adhesive sheet 18 and the engagement notch 32 and extends across the front plate 14. Note that the distance between the folding line 34 and the upper end of the front plate 14 matches the distance between the upper end of the back plate 12 and the adhesive sheet 18.

In the present embodiment, for example, three pairs of flaps, that is, a pair of main flaps 36m, a pair of sub-flaps 36s, and a pair of spare flaps 36p are formed on both side edges of the back plate 12. Specifically, the pair of main flaps 36m and the pair of sub-flaps 36s are separately arranged on the folding line 16 side and the upper end side of the back plate 12, and the pair of spare flaps 36p are arranged between the main flap 36m and the sub-flaps 36s. Has been placed.
Each of the above-described flaps 36 is partitioned by two cut lines 38 and one fold line (fold line) 40 (see FIG. 4). The two score lines 38 are spaced apart from each other in the longitudinal direction of the back plate 12 and cross the corresponding side edge of the back plate 12. The folding line 40 connects the inner ends of the cutting lines 38 to each other, and extends in the longitudinal direction of the back plate 12 along the adhesive sheet 18.

More specifically, as shown in FIG. 4, the cut line 38 includes a slit 38 a positioned on the adhesive sheet 18 side and a slit 38 b opened on the side edge of the back plate 18. The length is shorter than the length of the slit 38a. A breakable seam 42 is left between the slits 38a and 38b, and the length Lj of the seam 42 is, for example, about 2 mm.
Furthermore, is positioned immediately below the upper score line 38 is the application position 24 _L is disposed to partition and the main flap 36m in between the pair of main flaps 36m pasting position 24 _L and fold line 16 .

Meanwhile, the pair of sub-flaps 36s are disposed so as to sandwich the bonding position 24 _U from both sides, the lower side of the fold lines 38 defining the secondary flaps 36s is positioned directly below the bonding position 24 _U.
More specifically, in the case of this embodiment, when comparing the lengths of the flaps 36m, 36s, and 36p along the longitudinal direction of the back plate 12, the main flap 36m is longer than the auxiliary flap 36s and the auxiliary flap 36p. 36s and the spare flap 36p have the same length.

The insect trap described above is used by being assembled from the folded state shown in FIG. Hereinafter, the assembly of the insect trap will be described in detail.
When the insect trap is in the folded state of FIG. 1, the blank 10 is folded together with the adhesive sheet 18 covered with the release material 22 as described above, and the back plate 12 and the front plate 14 are attached to the release material 22 and the adhesive sheet 18. Via each other.

From such a state, the blank 10 is developed as shown in FIG. 2, and the release material 22 is peeled off from the adhesive sheet 18. Therefore, the pressure-sensitive adhesive surface 20 of the pressure-sensitive adhesive sheet 18 is exposed, and the sex pheromone attractant A and the food attractant B are adhered to the attachment positions 24 _U and 24 _L of the pressure-sensitive adhesive surface 20, respectively. Here, the attaching positions of the attractants A and B may be reversed.
Thereafter, the upper end portion of the front plate 14 is valley-folded along the folding line 34. That is, the upper end portion of the front plate 14 is folded toward the outer surface side of the front plate 14 to form the insertion tab 44. On the other hand, the engagement tab 28 is lifted from the inner surface of the back plate 12 along the cut line 26, and a gap is formed between the engagement tab 28 and the inner surface of the back plate 12.

Thereafter, the front plate 14 is folded again together with the adhesive sheet 18 along the folding line 16 toward the back plate 12. At this time, as shown in FIG. 5, the insertion tab 44 of the front plate 14 is partially inserted into the insertion gap. At this time, as apparent from FIG. 6, both side portions of the base of the engagement tab 28 are fitted into both V-shaped portions 32 _V of the engagement notch 32, whereby the engagement tab 28 and the engagement notch 32 are formed. Engage with each other.
As a result, the back plate 12 and the front plate 14 are detachably coupled to each other, so that the back plate 12 and the front plate 14 form a housing 17 shown in FIG. At this time, the through hole 30 of the engagement tab 28 matches the U-shaped portion 32 _U of the engagement notch 32, and the through-hole 30 and the U-shaped portion 32 _U cooperate with each other to form a hook hole 46. Form.
At this point, the assembly of the insect trap is completed, and the assembled insect trap is suspended via a hook hole 46 on a hook (not shown) protruding from, for example, an indoor pillar or wall surface.

On the other hand, both the V-shaped portions 32 _V of the engagement notch 32 are engaged with the base of the engagement tab 28 in spite of the above-mentioned distance D being equal to the length Lr of the back plate 12. As shown in FIG. 5, the front plate 14 is deformed in a curved state toward the outside. As a result, as shown in FIG. 7, there is a longitudinal section of the casing 17 between the back plate 12 and the front plate 14. In terms of surface, a crescent-shaped space S is secured. In FIG. 7, the aforementioned hook hole 46 is shown only by its axis.
Such spaces S are respectively opened on both side surfaces of the housing 17. Therefore, the components released from the sex pheromone attractant A and the food attractant B are filled in the space S, and further released from the space S to the outside of the housing 17. As a result, the pest to be captured is attracted by the above-described components and enters the space S, and the invading pest adheres to the adhesive surface 20 of the adhesive sheet 18 and is captured.

If the indoor space where the insect trap is installed is in a clean environment, the adhesive surface 20 has an adhesive surface 20 with a sufficiently long adhesiveness that is longer than the effective use period of the sex pheromone attractant A and the food attractant B. Maintained for a period of time.
However, if the insect trap is installed in a dusty environment such as in a factory of a mill, for example, the dust enters the space S of the housing 17 and adheres to the adhesive surface 20 of the adhesive sheet 18. End up. In this case, the adhesive surface 20 cannot maintain the original adhesiveness over the adhesion guarantee period, and as a result, the insect trapping performance by the insect trap is greatly reduced.
In this regard, when the insect trap of this embodiment is installed in an environment with a lot of dust, by raising at least one pair of the above-described three pairs of flaps 36m, 36s, and 36p, It becomes possible to cope with it.

In the case of the insect trap shown in FIG. 7, none of the three pairs of flaps 36m, 36s, and 36p is raised, and this embodiment of the insect trap of FIG. On the other hand, in the case of the insect trap shown in FIG. 8, the pair of main flaps 36m are folded toward the front plate 14 along the folding line 40 (see FIG. 4), so that they stand up together and face each other. doing. Such an embodiment of the insect trap shown in FIG. Further, in the case of the insect trap shown in FIG. 9, in addition to the pair of main flaps 36m, the pair of sub-flaps 36s are also erected in the same manner. Such an embodiment of the insect trap of FIG.
Furthermore, in the case of the insect trap shown in FIG. 10, all of the three pairs of flaps 36m, 36s and 36p are erected. Such an embodiment of the insect trap shown in FIG.

In any of the insect traps according to the first, second, and third aspects, the main flap 36m and the auxiliary flap 36s function as partitions. However, in any of the first to third embodiments, the main flap 36m, the auxiliary flap 36s, and the auxiliary flap 36p do not completely close the openings on both sides of the housing 17 as is apparent from FIGS. The opening is only partially closed. Therefore, in the case of the insect traps of Embodiments 1 to 3, the main flap 36m, the auxiliary flap 36s and the spare flap 36p reduce the intrusion of dust into the space S without hindering the invasion of pests into the space S. Therefore, the adhesion of dust to the adhesive surface 20 of the adhesive sheet 18 is greatly reduced.
As a result, when the insect trap is installed in a dusty environment, only the aspect of the insect trap (housing) is changed from the aspect 0 to the aspect 1, aspect 2 or aspect 3, The adhesiveness of the adhesive surface 20 in the adhesive sheet 18, that is, the pest capturing performance can be maintained over a long period of time.

When the flaps 36m, 36s, and 36p are in a state before being folded, a seam 42 is left in a part of the cut line 38 that defines the flaps 36. Therefore, since the flap 36 is connected to the other portion of the side edge of the back plate 12 by the joint 42, the flaps 36m, 36s, and 36p before folding do not flutter carelessly.
In order to verify the function of the standing main, auxiliary and spare flaps 36m, 36s, 36p, an exposure test device was prepared that reproduced dust environments with various dust concentrations. This exposure test apparatus will be described below with reference to FIG.

  The exposure test apparatus comprises a transparent exposing cage G that defines an exposure space therein. The exposed space is a cube with 50 cm on each side. The top plate of the exposure cage G has an air supply port Ain at the center thereof and an exhaust port Aout at the periphery thereof. The air supply port Ain and the exhaust port Aout are connected to an air supply source and an exhaust source, respectively. The supply and exhaust sources cooperate to generate an air flow that passes through the exposure cage G. The air flow rate here is 60 L / min.

On the other hand, in the exposure cage G, a quadrangular column P is disposed at the center thereof, and the quadrangular column P is positioned below the air supply port Ain. The width, depth, and height of the square pillar P are 17 cm, 14.5 cm, and 25 cm, respectively.
A cup C is disposed on the upper surface of the quadrangular column P. For example, wheat flour (variety: Yukichi) is accepted in the cup C as dust. For example, the cup C has a volume capable of receiving up to 90 g of flour, and the inner diameter and depth of the cup C are 7.5 cm and 4.5 cm, respectively.

Next, using the above-described exposure test apparatus, a test for exposing the assembled insect trap is performed in an environment having various dust concentrations. The specific procedure of this test will be described below.
(i) First, twelve insect traps T of embodiment 0 are prepared, and the total weight of these insect traps T is measured (the sex pheromone attractant A and the food attractant B are attached to each insect trap). Is).
(ii) Three insect traps T are stacked on each of the four sides of the quadrangular column P and suspended.

(iii) A test amount of flour as dust is put into the cup C on the square pillar P.
(iv) Supply and exhaust air to the exposure cage G, and generate an air flow passing through the exposure cage G continuously or intermittently at the above-described air flow rate. The generation of such an air flow is continued until all the flour in the cup C is scattered in the exposure cage G.
(v) Collect 12 insect traps T from the exposure cage G, and remove excess flour from these insect traps T.
(vi) Next, the test procedure from the above (i) to (v) is performed in a state where the dust amount (wheat flour amount) is different, and the insect trap T of the aspect 0 exposed under each dust condition is obtained. Get each.
(vii) The test procedure from the above (i) to (vi) is similarly performed on the insect traps of the embodiments 1 to 3, and the insect traps T of the embodiments 1 to 3 exposed under each dust condition. Get each.

On the other hand, an insect trap test device was prepared to verify the trapping performance of insect traps exposed to dust. This insect trapping test apparatus will be described below with reference to FIG.
The insect trapping tester includes a transparent trapping cage H, which defines a trapping space inside the trapping cage H, and this trapping space is a cube having a side of 50 cm.
The top plate of the insect trap cage H has an outside air inlet Bin at the periphery. On the other hand, the side wall facing the side wall of the insect trapping cage H on the outside air inlet Bin side has a suction port Bout near the bottom of the insect trapping cage H. The outside air inlet Bin is open to the outside air, while the suction port Bout is connected to a suction pump, for example. This suction pump sucks air in the insect trap cage H. Such air suction introduces air into the insect trap cage H through the outside air inlet Bin. Therefore, an air flow is generated that passes through the insect trap cage H, where the air flow rate is 250 ml / min.

Next, the insect trapping test of the insect trap T obtained under various dust environments is performed using the insect trapping test apparatus described above. The specific procedure of the capture test here will be described below.
(a) First, one of the insect traps T of the embodiment 0 is suspended from the inner surface of the insect trap cage H.
(b) 100 tobacco beetles are released in the insect trap cage H as capture targets. The tobacco beetle here was obtained by randomly collecting the tobacco beetles on the second day from among the tobacco beetles that appeared on the surface of the bait. Mixed.

(c) The insect trap cage H is placed in a room temperature of 30 ° C. and in a completely dark environment, and after 24 hours, the insect trap T is recovered from the trap cage H.
(d) The number of tobacco beetles captured by the insect trap T is measured.
(e) The test procedure from (a) to (d) is repeated four times for the insect trap T of the embodiment 0 exposed in the same dust environment, and the average number of insect traps and the insect trap of the embodiment 0 are collected. The average insect capture rate at T is calculated as a relative ratio. Here, the relative ratio is expressed by assuming that the average insect catching rate of the insect trapping device of the aspect 0 that is not exposed to dust is 1.00.
(f) The above-described test procedures (a) to (e) are similarly performed for the insect traps T of Embodiments 1 to 3, and the average trapping rate of the insect traps of Embodiments 1 to 3 is set as a relative ratio. To calculate.

The test results obtained by the above test procedure are shown in Table 1 below.

  As can be seen from Table 1, when the insect trap was installed in an environment with a lot of dust, the relative ratio of the catch rate in the insect trap of the embodiment 0 was greatly decreased as the amount of dust was larger. On the other hand, the relative ratio of the catch rate in the insect traps of Embodiments 1 to 3 did not decrease so much unless the amount of dust was extremely large. This can reduce the dust adhering to the adhesive surface 20 of the adhesive sheet 18 without preventing the insect traps of the aspects 1 to 3 from attracting and invading pests into the space S. As a result, the aspects 1 to 3 can be reduced. It shows that the insect trap can catch pests for a long time.

In an environment where the amount of dust is extremely large (for example, the amount of dust in Table 1 is 90 g), the relative ratio of catching rate in Mode 3 is much lower than the relative ratio of catching rate in Modes 1 and 2. I did not. At first glance, this shows that the better the insect trapping performance is, the smaller the opening on both sides of the insect trap (rod) is, but this is not true.
Specifically, the insect trapping performance of the insect trap is not determined only by the adhesiveness of the adhesive sheet 18, but also greatly depends on the ease of entry of the insect into the space S described above. That is, as the opening of the insect trap is reduced, the intrusion of dust into the space S can be reduced while the invasion of pests may be prevented. Therefore, in an environment with a lot of dust, it is necessary to select an insect trap to be used from among Embodiments 1 to 3 according to the size of the pest to be captured and the amount of dust.
In the case of the present invention, the main flap 36m, the width flap 36s, and the spare flap 36p are erected in accordance with the amount of dust and the size of the pest, so that any environment / pest can be dealt with.

なお、態様０'の虫捕獲器の場合もまた、態様０の虫捕獲器と同様に何れのフラップ３６も起立されていない。
表２から明らかなように、性フェロモン誘引剤Ａ及び食餌誘引剤Ｂの貼り付け位置は、害虫の捕獲性能に実質的に影響しなかった。このことは、性フェロモン誘引剤Ａ及び食餌誘引剤Ｂが背板１４及び粘着シート１８の任意の位置に貼り付け可能であることを示す。例えば、性フェロモン誘引剤Ａ及び食餌誘引剤Ｂは粘着シート１８の幅方向に隣接して貼り付けられていてもよい。 In the case of the insect trap of the above-described embodiment, the sex pheromone attractant A is pasted on the upper pasting position 24 _U , and the food attractant B is pasted on the lower pasting position 24 _L. In order to verify whether or not the attachment positions of these sex pheromone attractant A and diet attractant B affect the insect capturing performance, an insect trap of embodiment 0 ′ is prepared. The food attractant B is affixed to the upper attaching position 24 _U , and the sex pheromone attractant A is attached to the lower attaching position 24 _L.
A pest capture test was similarly performed on the insect trap of the embodiment 0 ′, and the results shown in Table 2 below were obtained.

In addition, in the case of the insect trap of aspect 0 ′, none of the flaps 36 stands up like the insect trap of aspect 0.
As is clear from Table 2, the attachment positions of the sex pheromone attractant A and the diet attractant B did not substantially affect the pest capturing performance. This indicates that the sex pheromone attractant A and the diet attractant B can be attached to arbitrary positions on the back plate 14 and the adhesive sheet 18. For example, the sex pheromone attractant A and the diet attractant B may be attached adjacent to each other in the width direction of the pressure-sensitive adhesive sheet 18.

The present invention is not limited to the above-described embodiment, and various modifications are possible.
For example, the spare flap 36p shares the cut line 38 with the main flap 36m and the sub flap 36s, but may be partitioned by the cut line of only itself.
Moreover, the insect trap may be provided with four or more pairs of flaps. Further, the flaps may be disposed on both side edges of the front plate 14 instead of the back plate 12, or may be disposed on both the back plate 12 and the front plate 14.
If it is necessary to stabilize the standing posture of the flap, for example, a slot may be formed in the front plate or the back plate, and the raised flap may be partially inserted into the slot.
Furthermore, the insect trap is not limited to being suspended when in use, and may be disposed at a desired location with the back plate 12 facing down.
Finally, it goes without saying that the means for hanging the insect trap and the means for coupling between the back plate and the front plate can be variously changed.
