Description

Technical Field

[0001] The invention relates to the technical field of biological breeding, and in particular to a habitat device for water lice. Background Art

[0002] Mangroves are woody plant communities unique to tropical and subtropical bays and estuary mudflats. They are located at the junction of land and sea and are a special ecosystem that transitions from land to sea. Mangrove wetlands are ecosystems with complex and complete structures and functions. They are one of the most productive and valuable ecosystems on Earth. However, because they are located in coastal areas with fragile ecological environments, they are fragile ecosystems that are difficult to restore once destroyed.

[0003] Sphaeroma spp. belongs to the phylum Arthropoda, class Crusatacea, order Isopoda, family Sphaeromatidae, genus Sphaeroma. It is one of the most common groups of crustaceans in the order Isopoda, and is named because its body curls up into a ball when encountering external stimuli.

[0004] The damage caused by water lice to mangrove plants is mainly caused by the water lice's drilling and borehole behavior. A large number of drillings will damage the roots and basal parts of mangrove plants, causing their root systems to shrink faster, making them more likely to break, fall over and die under the impact of wind and waves. Due to the outbreak of water lice, the mangroves in Dongzhaigang are still showing a clear trend of degradation, and mature forests in the late stage of zonal succession have become the main targets of water lice. Mangrove wetlands are an important ecosystem. Once a water lice disaster breaks out, the damage to mangrove plants is almost devastating. Therefore, it is of great significance to strengthen research on the biology, outbreak mechanism, monitoring methods and prevention and control measures of water lice.

[0005] Since water lice usually bore holes in the base of dead or alive mangrove trunks, the wood they bore is mostly hard and the structure of the holes is complex, making it difficult to remove directly. Usually, the water lice inside are removed by violently splitting the wood. In the process of removing the water lice, it is easy to damage and miss a large number of water lice individuals. Even complete water lice individuals will have certain hidden injuries, which adds a lot of uncertainty to later research. Therefore, it is possible to provide a device that is suitable for the life of water lice in the holes and is convenient for obtaining water lice in the holes, which is of great help to the research on the habits of water lice such as holes, growth, reproduction, and ecological monitoring. At present, there are no reports on experimental devices related to the biological research and monitoring of water lice. Summary of the invention

[0006] The purpose of the present invention is to provide a habitat for water lice to solve the problems existing in the above-mentioned prior art and provide a place for water lice to live in holes.

[0030] Embodiment 1

[0031] like Figures 1 to 5 As shown, in this embodiment, a living device for water lice is provided, including a board layer 1 and a fixing member, a plurality of board layers 1 are stacked to form a three-dimensional figure, each board layer 1 is connected and fixed by a fixing member, a plurality of shallow holes are arranged on the surface of the three-dimensional figure, the shallow holes are temporary shelters for water lice, and the board layer 1 is a material that water lice can bore holes in. In this embodiment, the three-dimensional figure can be a cube, a prism, a cylinder, or an irregular body, simulating a solid wood trunk, and the board layers 1 are stacked to form the main part of the living.

[0032] As an optional solution, the present embodiment further includes at least one counterweight block 2, which is arranged on the plate layer 1 to facilitate the three-dimensional figure to sink into the water.

[0033] As an optional solution, in this embodiment, the counterweight 2 is arranged at the bottom layer or the top layer of the plate layer 1, or at both sides; the thickness of the counterweight 2 is greater than the thickness of the plate layer 1; the material of the counterweight 2 includes glass, ceramic or cement, or stone, brick and other heavy objects. Among them, the counterweight 2 is used to increase the overall weight of the device so that the device can sink in water.

[0034] As an optional solution, the material of the board layer 1 in this embodiment includes solid wood or soft sandstone, and the material is preferably dead wood of mangrove plants that are easily harmed by water lice.

[0035] As an optional solution, in this embodiment, the thickness of the board layer 1 is 1 mm-5 mm. According to the borehole pattern of water lice, the thickness of the board is preferably 2 mm-3 mm.

[0036] As an optional solution, the shallow hole in this embodiment is a round hole with a diameter of 2mm-5mm and a depth of 5mm-10mm. In the initial use of the device of this embodiment, the round shallow hole can serve as a temporary shelter for the water lice.

[0037] As an optional solution, the fixing member in this embodiment includes at least one of an elastic band 3, a bolt and a U-shaped slot. The elastic band 3 is used to keep the multiple board layers 1 and the counterweight 2 in contact with each other. The elastic band 3 is preferably a rubber band or an elastic rope. The elasticity of the elastic band 3 not only facilitates the assembly and disassembly of the board layer 1, but also prevents the multiple board layers 1 from absorbing water and expanding to damage the elastic band 3. It is a simple living device suitable for indoor experimental research.

[0038] As an optional solution, the fixing part in this embodiment includes a fixing seat 6 and a fixing rod 8. The two outermost board layers 1 are each provided with a fixing seat 6. The fixing rod 8 passes through all the board layers 1 and the fixing seat 6, and is connected to the fixing seat 6 through a positioning pin 7, so that the board layers 1 are penetrated into a whole.

[0039] As an optional solution, in this embodiment, a pressure plate 4 and a spring 5 are arranged in sequence between the fixing seat 6 and the outermost board layer 1. The cross-sectional diameter of the spring 5 is larger than the diameter of the through hole on the pressure plate 4. The pressure plate 4 is pressed tightly by the elastic force of the spring 5, and then the board layer 1 is pressed tightly to form a whole. The fixing rod 8 is a water pipe made of polyvinyl chloride, which is low in cost and corrosion-resistant. A through hole for the fixing rod 8 to pass through and a ring groove for embedding the spring 5 are provided in the center of the pressure plate 4. The fixing seat 6 is provided with a through hole for the positioning pin 7 and a ring groove for embedding the spring 5. The pressure plate 4 is located on the upper and lower sides of the main part of the habitat, and the elastic force applied by the spring 5 can be evenly distributed to the surface of the board layer 1, and the side structure of the board layer 1 at both ends can also be protected. The elastic force of the spring 5 can ensure that the board layers 1 fit tightly together, and also provide space for the board layer 1 to expand longitudinally after absorbing water.

[0040] As an optional solution, the length of the fixing rod 8 in this embodiment is twice the total thickness of all the board layers 1. When used in the field, the fixing rod 8 can be fixed by inserting the part of the fixing rod 8 beyond the board layer into the ground. There are several pairs of pin holes evenly distributed on the fixing rod 8. The spacing between the pin holes at both ends is greater than the spacing between the connecting hole groups on the two fixing seats 6. The pin holes and the connecting hole groups are used to connect the positioning pins 7. The pin holes are preferably equidistant and vertically alternately arranged to ensure the strength of the fixing rod 8. The lower end of the fixing rod 8 is used for field placement and fixing. By connecting different pin holes on the fixing rod 8, the height adjustment of the overall structure from the ground can be achieved. It is a standard habitat device suitable for field research and monitoring.

[0041] This embodiment can design a simple habitat device suitable for indoor experimental research and a standard habitat device suitable for field research and monitoring according to the purpose and usage scenario.

[0042] Embodiment 2

[0043] This embodiment provides a simple habitat device for studying the reproduction of water lice, and the specific structure is as follows:

[0044] like Figure 4As shown, the dead mangrove plant Tung tree can be used as the material for the board layer 1, and the trunk of the Tung tree is cut into a thin plate with a length, width and thickness of 60mm and a thickness of 2mm. 14 sheets of board layers 1 are neatly stacked together to form the main body of the habitat, and at the same time, a 4mm drill bit is used to drill circular holes with a depth of 10mm on the four sides of the habitat body, and 3-4 circular holes are randomly drilled on each side. The counterweight block 2 is a glass plate with a length, width and thickness of 60mm and a thickness of 10mm. The binding rope 3 uses a rubber band with a circumference of 140mm and a width of 15mm. The above-mentioned simple habitat device in this embodiment can be used to place 10-20 mature individuals of water lice.

[0045] The reproduction of water lice is sexual reproduction, and mating, egg laying and larval growth are completed in the borehole. In order to study the reproduction process of water lice indoors, it is necessary to provide a borehole environment suitable for water lice to live. The simple habitat device of this embodiment can provide an environment for water lice to live in the borehole, and the design of the multi-layer thin plate structure can facilitate the later observation and acquisition of water lice inside the borehole.

[0046] Embodiment 3

[0047] This embodiment provides a standard habitat device for monitoring water lice in mangroves and early warning of pests, and the specific structure is as follows:

[0048] like Figure 1 As shown, recently dead mangrove trunks are selected as materials for making board layer 1. The selected trunks must be straight, with no damage to the epidermis and a diameter of about 12 cm. The qualified trunks are cut into 30 cm long wooden stakes, and a 25 mm diameter through hole is drilled in the center of the wooden stake. The drilled wooden stakes are cut horizontally into 3 mm thick thin wood slices, and 50 continuous thin wood slices are selected as board layer 1. In this embodiment, PVC material is used to make the pressing plate 4, the fixing seat 6 and the positioning pin 7. The parameters of the pressing plate 4 are selected as 25mm inner diameter, 120mm outer diameter and 10mm thickness; the fixing seat 6 is selected as 25mm inner hole diameter, 80mm outer diameter and 50mm; the aperture of the pin hole of the positioning pin 7 is selected as 10mm; the spring 5 is selected as 316L stainless steel material, with specifications of 2mm*30mm*30mm (wire diameter*outer diameter*total length); the fixing rod 8 is selected as a PVC water pipe with a diameter of 25mm and a length of 100cm. The fixing rod 8 is drilled with 10 vertical alternate holes with an interval of 50cm and an aperture of 10mm at one end of the mounting plate layer 1. The standard habitat device of this embodiment can be put into use in the wild, so that the water lice can attach themselves.

[0049] Water lice are common in mangrove ecosystems. When the population of water lice exceeds a certain threshold, the mangrove ecosystem will lose balance and become an insect pest. By installing a certain number of standard habitats in the mangrove ecosystem and regularly monitoring the burrowing conditions and population of water lice in the habitats, early warning of water lice pest outbreaks can be provided.

[0050] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
