Description

Technical Field

[0001] This utility model relates to the field of arthropod migration research technology, and in particular to a two-way trap device for collecting terrestrial reptiles at habitat boundaries. Background Technology

[0002] Farmland ecosystems are home to a variety of arthropods, among which harmful organisms pose the greatest threat to crops. To better understand the relationship between agricultural planting and arthropods, it is necessary to study the behavior of these arthropods that live and inhabit farmland and field ridges on a relatively small scale. In particular, it is important to study the migration behavior and movement patterns of these arthropods. Such research will contribute to the analysis of the growth environment in the agricultural field and the sustainable development of agricultural ecosystems.

[0003] Arthropods primarily harm crops, exhibiting damage through direct grazing of roots, stems, and leaves; the spread of bacteria, fungi, and viruses; and disruption of crop growth structures. Therefore, research into the habits of arthropods in farmland is necessary to facilitate crop protection.

[0004] Current research on this type of arthropod mainly focuses on analyzing its species, population size, and environmental variables. These environmental variables primarily include meteorological factors (such as temperature, air pressure, rainfall, and wind speed) and vegetation types (such as crop types). Current research needs to analyze the habits of arthropods through sampling under multiple environmental variables. However, existing capture methods can only obtain data on arthropod species, population size, and environmental variables, but cannot determine the migration direction of terrestrial arthropods under different environments, resulting in a lack of understanding of terrestrial arthropod migration under various conditions. Existing technology lacks a two-way trap device that can distinguish migration direction, is highly stable, and is easy to maintain.

[0005] Based on this, the present invention designs a two-way trap device for collecting terrestrial reptiles at habitat boundaries to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a two-way trap device for collecting terrestrial arthropods at habitat boundaries. Through the insect traps, arthropods in farmland and along field ridges can be captured and sampled. A barrier is added to capture arthropods migrating in different directions. By trapping insects on different sides of the barrier, arthropods migrating away from crops in the farmland and those migrating from field ridges into the farmland can be captured. Therefore, the migration direction of arthropods can be effectively obtained, and the migration habits of different arthropod species can be understood based on actual environmental variables. This allows for dynamic monitoring of arthropod communities at farmland habitat boundaries and assessment of their ecological functions.

[0007] This invention is implemented as follows: a two-way trap device for collecting terrestrial arthropods at habitat boundaries, comprising:

[0008] Insect traps, ground stakes, and barriers;

[0009] The insect trap is a bowl-shaped container with an open top. The edge of the top opening of the insect trap is also provided with an annular eaves plate. The eaves plate extends outside the insect trap and is a sloping funnel structure with a higher outer edge and a lower inner edge. Multiple locking rods are also evenly arranged around the outer edge of the eaves plate, and each locking rod extends upward above the eaves plate.

[0010] The insect trap is embedded below the ground, and the outer edge of the eaves is flush with the ground.

[0011] The ground spikes are straight rod-shaped long spikes, with two ground spikes forming a group. Each group of ground spikes is fastened to a snap-fit ​​device, and the ground spikes are vertically inserted into the ground.

[0012] The barrier is a smooth, long, flexible flat plate;

[0013] Two ground spikes from the same group are clamped on the inner and outer sides of the barrier. The barrier is stably and vertically inserted into the ground by multiple groups of ground spikes, and the barrier is limited by the bending of each group of ground spikes.

[0014] The balustrade is connected to the outer edge of the eaves board in an arc shape by a clamp;

[0015] Insect traps are installed on both sides of the barrier.

[0016] Furthermore, the eaves and the insect trap are a sealed, integral structure;

[0017] The tops of the insect trap and the eaves are both smooth mirror surfaces;

[0018] The included angle S of the inclined surface of the eaves is 45°.

[0019] Furthermore, the clamping rod is a straight rod, and the bottom of the barrier plate is engaged with and clamped to the clamping rod, and the barrier plate is bent by the clamping rod.

[0020] Furthermore, the insect trap is filled with a collection liquid.

[0021] Furthermore, labels are affixed to both sides of the barrier.

[0022] Furthermore, the snap-fit ​​component has a flat plate structure and two mounting holes are provided on the snap-fit ​​component. The upper ends of the two ground nails in the same group are inserted into the two mounting holes of the same snap-fit ​​component.

[0023] The lower end of the ground nail is a spike.

[0024] The beneficial effects of this utility model are: 1. This utility model adds a barrier to form a boundary between different crops, so that the barrier becomes a habitat boundary, and arthropods within the habitat boundary range can be captured and studied. It can also effectively avoid the mutual influence and confusion of arthropods in different habitat boundary ranges during migration, ensuring that the captured arthropods are within the habitat range, and can effectively eliminate the influence of other habitats on the study.

[0025] 2. This device uses ground nails and the clamps of the insect trap to compress and limit the barrier, allowing the barrier to bend and deform according to the actual ground shape. This makes the device adaptable to various field ridge shapes and facilitates the installation of the insect trap. It can also bend and adapt to the actual habitat boundary shape to achieve accurate isolation and interception. In addition, the device is simple to install and easy to set up, which is conducive to large-scale installation and use.

[0026] 3. The insect trap of this device can effectively capture arthropods and is combined with the barrier. The addition of the eaves allows for the capture of arthropods over a wider area. The insect trap is embedded in the ground, so it is not affected by other animals and does not affect the movement of people. Because it is a sunken structure, it effectively reduces the escape rate of highly active species and improves the accuracy of data. Attached Figure Description

[0036] Please see Figures 1 to 6 As shown, this utility model provides a two-way trap device for collecting terrestrial reptiles at habitat boundaries. To better understand the above technical solution, the following will describe the above technical solution in detail with reference to the accompanying drawings and specific embodiments.

[0037] In a specific embodiment of the technical solution of this utility model:

[0038] Includes insect trap 1, ground pegs 2, and barrier 3;

[0039] The insect trap 1 is a bowl-shaped container with an open top. The inside of the insect trap 1 is filled with a collection liquid, which can be composed of laundry detergent solution and ethanol. The liquid level only needs to be half the depth of the insect trap 1 to effectively capture arthropods.

[0040] The top edge of the insect trap 1 is also provided with a ring-shaped eaves 11. The eaves 11 is a sloping funnel structure with a higher outer edge and a lower inner edge. Multiple locking rods 12 are evenly arranged around the outer edge of the eaves 11, with each locking rod 12 extending upward above the eaves 11.

[0041] The inner edge of the eaves 11 and the top opening edge of the insect trap 1 are integrally formed and sealed.

[0042] The tops of the insect trap 1 and the eaves 11 are smooth mirror surfaces, which facilitates the arthropods to slide down and fall into the interior of the insect trap 1.

[0043] The included angle S of the inclined surface of the eaves 11 is 45°. This structure allows arthropods entering the eaves 11 to tend to slide into the trap 1, which facilitates the guided trapping of arthropods passing through.

[0044] The insect trap 1 is embedded below the ground, and the outer edge of the eaves 11 is flush with the ground. This annular eaves 11 surrounds the top edge of the insect trap 1, making the trap 1 have a larger capture range. At the same time, its surface is smooth and has a slope, so that passing arthropods will slide into the trap 1. Furthermore, the collected liquid has a good killing and preservation effect.

[0045] The eaves 11 are set outside the top opening of the insect trap 1. The eaves 11 extend outward outside the insect trap 1, making the receiving and capturing range of the top opening of the insect trap 1 larger, so as to capture more insects.

[0046] Ground nail 2 is a straight rod-shaped long nail, with a spike at the lower end.

[0047] Two ground nails 2 form a group, and each group of ground nails 2 is fastened onto a snap-fit ​​piece 21, with the ground nails 2 vertically inserted into the ground;

[0048] The snap-fit ​​component 21 has a flat structure and two mounting holes 22 are provided on it. The upper ends of the two ground nails 2 of the same group are inserted into the two mounting holes 22 of the same snap-fit ​​component 21, and the two ground nails 2 of the same group are parallel to each other; thus, the two ground nails 2 are stably inserted into the same snap-fit ​​component 21, and the barrier plate 3 is clamped and positioned by the two ground nails 2.

[0049] By installing ground nails 2 at different locations, the barrier 3 can be bent and deformed according to the positions of the ground nails 2.

[0050] The barrier 3 is a smooth, long, flexible flat plate. Labels 31 are attached to both sides of the barrier 3 to mark crops in different directions, so as to facilitate the recording of arthropods captured in the traps 1 on different sides and effectively avoid crop recording errors and confusion.

[0051] A ground nail 2 is installed on each of the inner and outer sides of the barrier 3. Two ground nails 2 in the same group are clamped on the inner and outer sides of the barrier 3. The barrier 3 is stably and vertically inserted into the ground by multiple groups of ground nails 2. The barrier 3 is limited by bending by each group of ground nails 2, so that the ground nails 2 become bending positioning rods of the barrier 3.

[0052] The balustrade 3 is connected to the outer edge of the eaves board 11 in an arc shape by the clamp 12;

[0053] Insect traps 1 are installed on both sides of the barrier 3;

[0054] The clamp rod 12 is a straight rod. The bottom of the barrier plate 3 is connected and clamped to the clamp rod 12. The barrier plate 3 is supported and bent by the clamp rod 12. The bending stress of the barrier plate 3 is borne by the ground nail 2 and the clamp rod 12. As needed, the clamp rod 12 can be supported on the concave surface of the barrier plate 3 or on the convex surface of the barrier plate 3. The method of use depends on the terrain of the field ridge. Just make sure that the bottom of the barrier plate 3 is tightly inserted into the ground. Therefore, under normal circumstances, the barrier plate 3 needs to be inserted 1cm to 5cm below the ground. At this time, the clamp rod 12 should not be in contact with the barrier plate 3. Just set the clamp rod 12 on the concave surface of the barrier plate 3 to support its stress. This will prevent the soft soil from losing sufficient support for the bending stress of the barrier plate 3 and will also effectively prevent the barrier plate 3 from deforming due to bending and wind.

[0055] It should be noted that:

[0056] 1. Habitat boundary refers to the boundary of the ecological environment on which a species or species group depends for survival. This device is aimed at the boundary that different arthropods need to pass through when migrating between different crop environments, such as rice paddies and alfalfa. The arthropods living in these two environments may have overlapping species or different populations. The arthropods living in these different crops also have different migration methods. The purpose of this device is to distinguish the migration direction of arthropods within the boundary of different habitats, such as rice paddies and alfalfa.

[0057] 2. Current traps are simply single collection containers, capable of capturing arthropods that happen to be passing by, resulting in low insect-catching efficiency. This device adds a barrier 3, which can intercept crawling arthropods and guide them into the area of ​​the eaves 11 of the trap 1. Because the barrier 3 of this device has the same curved shape as the edge of the eaves 11, arthropods have a tendency to crawl along the boundary of the intercepted object after being intercepted. This device utilizes this characteristic to guide arthropods into the capture range of the trap 1, making the capture efficiency higher.

[0058] 3. This device can set up an insect trap 1 on each side of the barrier 3, so that the insect trapping method is divided into independent two-way trapping spaces, which can isolate and capture arthropods within different habitat boundaries without interfering with each other. This is an important basis for accurately judging the migration direction of arthropods. When arthropods outside the habitat enter the habitat, they are captured by the insect trap 1 outside the habitat, and when arthropods inside the habitat enter the habitat, they are captured by the insect trap 1 inside the habitat. It can obtain the types and numbers of captured arthropods, as well as the migration direction of these arthropods in different habitats.

[0059] When installing and using it, first determine the matching shape of the fence 3 and the field ridge. Then, support the fence 3 first, and then place a ground nail 2 on each of the inner and outer sides of the fence 3, with the tip of the ground nail 2 facing down and inserted into the field ridge so that the insertion depth of the ground nail 2 can provide sufficient support.

[0060] The design length of barrier 3 is required to surround and isolate the habitat boundary, ensuring that the experimental field is within an isolated environment.

[0061] Depending on the shape of the different field ridges, the barrier 3 is set up to vertically isolate the habitat, forming a barrier wall effect.

[0062] The insect trap 1 is a 2000mL plastic container, 13.5cm high and 17.5cm in diameter.

[0063] The distance between two adjacent insect traps 1 on the inner and outer sides should be about 30cm. The height of the barrier 3 should be 30cm.

[0064] When it is necessary to install the insect trap 1, the barrier 3 is bent and deformed, such as... Figure 1 As shown, a set of ground nails 2 are set on each side of the bend, that is, ground nails 2 are set on both the inner and outer sides to clamp the barrier 3. Then, the snap fastener 21 is installed so that each of the two ground nails 2 is inserted into a mounting hole 22, and the bottom of the snap fastener 21 is abutted against the top of the barrier 3.

[0065] At the same time, a hole is dug at the curved concave surface at the bottom of the barrier 3. After the hole is dug, the insect trap 1 is placed into the hole, and the curved shape of the barrier 3 is made to match the curved arc edge of the eaves 11. The clamping rod 12 is then placed against the curved concave surface of the barrier 3 to complete the installation.

[0066] The term "inside" in this context refers to the area within the habitat boundary of the experimental field, while "outside" refers to the area outside the habitat boundary.

[0067] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
