Hereinafter, the present invention will be described in detail with reference to the attached drawings.

Figure 1 is a schematic diagram of an adhesive trap for capturing microarthropods according to the present invention.

The adhesive trap (1) for capturing microarthropods according to the present invention includes an attractant discharge unit (10) capable of releasing an attractant in a gaseous state, a trap housing (20), a gas hole (30), and a trap unit (Figure 3 to 6).

In the present invention, microarthropods refer to small animals belonging to the phylum Arthropoda and may include insects, spiders, and crustaceans. Specifically, the microarthropods may include small harmful animals such as ticks, including small ticks. Hereinafter, an embodiment of the present invention will be described using microarthropods as mites as an example.

Ticks are known to seek out animals and people in response to carbon dioxide produced when they breathe. Therefore, the adhesive trap 1 according to an embodiment of the present invention can use carbon dioxide as an attractant for mites or the like.

The trap housing 20 includes an attractant release portion 10 capable of generating and releasing carbon dioxide, an attractant, therein.

Components that can produce carbon dioxide as an attractant may include sugar (12) and yeast (14). Sugars 12 and yeast 14 may contact each other to produce carbon dioxide as a reaction product. At this time, the yeast 14 may be dry yeast.

In the step of preparing the adhesive trap 1 according to the present invention, the sugars 12 and yeast 14 may be provided separately in a packaging bag, etc. Saccharides 12 and yeast 14 are contained and mixed in the trap housing 20 when the adhesive trap 1 according to the present invention is placed in a forest, meadow, lawn, etc. to capture ticks, etc. Sugars (12) and yeast (14) react with each other to produce carbon dioxide.

In the trap housing 20, the sugars 12 and yeast 14 are provided in separate areas separated by a separation plate, and the sugars 12 and yeast 14 are mixed with each other by removing the separation plate and shaking it. It can be brought into contact. The present invention includes a configuration that releases carbon dioxide from the inside of the trap housing (20) when the sticky trap (1) is placed at the tick capture site, and excludes providing an attractant release unit in various ways not described herein. I never do that.

Additionally, according to an embodiment of the present invention, the attractive ingredient capable of attracting the microarthropods may be carbon dioxide, but is not limited thereto, and for example, pheromones for attracting microarthropods may also be applied.

The trap housing 20 includes a removable cover 24 (see FIGS. 3 to 6) and contains an attractant therein. When installing the adhesive trap (1), the cover (24) is removed, the ingredients forming the attractant release portion (10) are placed in the inside (22), the cover (24) is covered, and the trap is placed at the tick capture location.

The trap housing 20 is shown as a hexahedron with a square wall 25, but is not limited thereto and may be formed into various three-dimensional structures. Referring to FIG. 2, the trap housing 20 may be formed as a tetrahedron with a triangular wall surface 25. The wall surface 25 of the trap housing 20 has an external surface 26 exposed to the outside and an internal surface 28 located inside.

As clearly visible in the enlarged view of portion A of FIG. 1, the trap housing 20 may be provided with a gas hole 30 through which attractants such as carbon dioxide can be discharged. The gas hole 30 is formed through the wall 25 of the trap housing 20. Attractants such as carbon dioxide are discharged to the outside of the trap housing 20 through the gas hole 30 and spread to the surroundings.

The inner surface 28 of the trap housing 20 includes an access passage 32 that is connected to the gas hole 30 and extends protruding from the inner surface 28. Since the end of the entry passage 32 is positioned spaced apart from the inner surface 28, it is advantageous to allow microarthropods such as mites to enter the inside while preventing them from moving outward.

According to an embodiment of the present invention, the end of the entry passage 32 is provided with a flange portion 34 whose flange extends in a funnel shape in the outer circumferential direction. The tick enters the inside through the entry passage 32, falls to the floor inside the trap housing 20, and is captured inside the trap housing 20 (22). The flange portion 34 extending in the shape of a funnel gradually widens the entry passage 32, so it may be advantageous for ticks to naturally enter along the entry passage 32 and induce a fall. In addition, ticks that have fallen to the inner bottom surface of the trap housing 20 can climb on the inner surface 28 of the trap housing 20, including the entry passage 32 extending from the inner surface 28 and the end thereof. The flange portion 34 is advantageous in preventing ticks from escaping to the outside through the entry passage 32.

As shown in Figure 2, the outer surface 26 of the trap housing 20 extends at an obtuse angle θ1 with respect to the ground surface and the inner surface 28 extends at an acute angle θ2 with respect to the floor surface 25. ) can be formed to have. For example, when the trap housing 20 is formed as a tetrahedron, it has the wall surface 25. In this case, when the tick climbs the outer surface 26 of the trap housing 20, the outer surface 26 has a gentle slope less than vertical with respect to the ground, which is advantageous for movement. In contrast, when a tick captured inside the trap housing 20 climbs on the inner surface 28, the inner surface 28 forms a steeper slope than the vertical with respect to the floor surface, so it is not easy to move, which is advantageous for capture.

Referring to FIG. 3, a trap portion on which an adhesive layer 41 is formed is formed on the outer surface 26 of the trap housing 20.

According to an embodiment of the present invention, the trap portion may be formed as a V-shaped adhesive groove 40 recessed in the wall 25 of the trap housing 20.

The V-shaped adhesive groove 40 has a first inclined surface 42 without the adhesive layer 41 and a second inclined surface 44 on which the adhesive layer 41 is formed, and the first inclined surface 42 and the second inclined surface 44 are formed. The inclined surface 44 can be captured by attaching the back part of the tick to the adhesive layer 41 of the second inclined surface 44 while the tick progressing along the first inclined surface 42 moves toward the inner end 45. It is formed as a sharp V-shaped adhesive groove 40 with a gap 46 formed thereto. In the V-shaped adhesive groove 40, the first inclined surface 42 and the second inclined surface 44 extend obliquely to each other as the gap becomes smaller toward the inner end 45, and the gap 46 extends to the first inclined surface 42. ) The back portion of the microarthropod entering the inside of the V-shaped adhesive groove is formed to be able to contact the second inclined surface.

Referring to FIG. 3, the V-shaped adhesive groove 40 forming the trap portion extends in the height direction of the trap housing 20. It extends between the upper edge 29b and the lower edge 29c on the outer surface 26 on either side of the side edge 29a of the trap housing 20.

As can be seen in the enlarged view of part B of FIG. 3, the V-shaped adhesive groove 40 is used to increase the depth of the V-shaped adhesive groove 40 without increasing the thickness of the wall surface 25 of the trap housing 20. ) may be formed to be inclined to one side based on the direction passing through the wall 25. In this embodiment, the first slope 42 is gently angled against the outer surface 26 of the trap housing 20 and the second slope 44 is then angled relative to the outer surface 26 of the trap housing 20. It has a steep slope. In this case, the inner end 45 of the V-shaped adhesive groove 40 is located at the inward lower part of the housing outer surface 26 leading to the second inclined surface 44. This arrangement is advantageous for forming the gas hole 30 penetrating the first inclined surface 42 in the thickness direction of the wall surface 25.

The arrangement of the V-shaped adhesive groove 40 may be advantageous in guiding ticks to move along the gentle slope of the first slope 42. Since the gap 46 of the V-shaped adhesive groove gradually becomes smaller toward the inner end 45, the back of the tick moving inward along the first inclined surface 42 touches the second inclined surface 44. An adhesive layer 41 is formed on the second inclined surface 44. Accordingly, the tick is captured with its back attached to the second slope 44.

According to the research of the researcher of the present invention, there are cases where ticks move along a wall and when their legs touch the adhesive layer, they recognize the adhesive layer as an obstacle and move around. When a tick moves, only part of its frontmost leg touches the adhesive layer, and if the degree of adhesion does not reach the level to capture the tick, the tick takes its feet away from the adhesive layer and moves to avoid the adhesive layer. However, as in the present invention, when the adhesive groove is formed so that the back part of the tick touches the adhesive layer while moving, the tick cannot find the adhesive layer and is captured. Through this, the tick capturing ability of the adhesive trap (1) can be improved.

In Figure 3, the formation area of the gas hole 30 and the formation area of the V-shaped adhesive groove 40 are formed separately and spaced apart from each other. V-shaped adhesive grooves 40 are formed adjacent to the corners of the trap housing 20, and a plurality of gas holes 30 are formed in the middle portion of the outer surface 26 of the wall 25.

Carbon dioxide emitted through the gas hole 30 inside the trap housing 20 spreads to the surroundings. Ticks attracted by carbon dioxide meet the gas hole 30 while moving up and climbing the wall of the outer surface 26 of the trap housing 20, and the mites that enter the gas hole 30 are captured inside the trap housing. . Ticks that meet the adhesive groove 30 are captured with their backs attached to the second inclined surface 44.

Referring to FIG. 4 , the gas hole 30 may be formed on the first inclined surface 42 of the adhesive groove 40. Ticks that have moved to the V-shaped adhesive groove (40) are captured by entering the inside of the trap housing (20) through the gas hole (30) at the first slope (42), or their backs are attached to the second slope (44). captured.

Figure 4 shows the gas hole 30 and the V-shaped adhesive groove 40 arranged adjacent to only the side edge 29a of the trap housing 20, but the present invention is not limited thereto. A gas hole 30 may be formed on the outer surface 26 between the side edges 29a, and as shown in FIG. 5, a V-shaped adhesive having the gas hole 30 on the first slope 42 A plurality of grooves 40 may be formed side by side on the outer surface 46.

Referring to FIG. 6, it can be seen that the V-shaped adhesive groove 40 is not limited to being formed in the height direction on the outer surface 26. The V-shaped adhesive groove 40 is formed to extend in a parallel direction, that is, to the side, on the bottom surface, and the V-shaped adhesive groove 40 is not continuously extended between both edges, but can be arranged discontinuously. It shows. Referring to FIG. 6, a gas hole 30 is disposed between the V-shaped adhesive groove 40 on the outer surface 26 of the trap housing 20, or gas holes 30 are disposed on both sides of the V-shaped adhesive groove 40. ) are arranged so that the gas hole 30 and the V-shaped adhesive groove 40 are spaced apart. As shown in the enlarged view of part C of FIG. 6, the first inclined surface 42 of the V-shaped adhesive groove 40 extends parallel to the bottom surface, and the second inclined surface 44 located on the upper part is located at the inner end ( It extends obliquely toward 45) to approach the first inclined surface 42. A gap 45 is formed between the first inclined surface 42 and the second inclined surface 44 so that the back portion of the tick moving toward the inner end can be attached as the gap 45 gradually becomes smaller.

A release film may be attached to the surface where the adhesive layer 41 is formed in the V-shaped adhesive groove 40, so that the release film can be removed when the adhesive trap is placed.

Additionally, the adhesive layer may contain entomopathogenic fungi. Entomopathogenic fungi infect microarthropods captured in the adhesive layer and also infect surrounding microarthropods, effectively reducing the population of microarthropods.

Meanwhile, the trap housing 20 may be made of biodegradable material. Biodegradable materials may include at least one of biodegradable polymers and vegetable waste resources. The biodegradable polymer may include at least one selected from the group consisting of cellulose, cellulose ether, lignin, gelatin, and agar. In addition, the vegetable waste resources may include at least one selected from the group consisting of corn meal, corn stalks, corn silk, potato starch, sweet potato starch, pine needles, rice straw, arrowroot vines, sawdust, wood flour, rice husk, leaves, and thinning by-products. You can. When using the vegetable waste resources, the trap housing 20 can be manufactured using biodegradable polymer as a binder.

In this way, the V-shaped adhesive groove 40 and the gas hole 30 are formed in various arrangements in the trap housing 20, so that the back part of the tick is attached to the second slope of the V-shaped adhesive groove 40 and captured, Ticks that have moved to the inside of the trap housing (20) through the gas hole (30) are captured in such a way that they are trapped inside. Microarthropods such as ticks that are attracted by an attractant and captured in an adhesive trap are captured inside the trap housing or in the adhesive layer and die.
