Abstract
Description
Technical Field
[0001] This utility model relates to the field of pest control technology, and more specifically, to a biological control device and its pest control system. Background Technology
[0002] Currently, pest control methods in the field include physical control and biological control. Physical control uses physical means to directly interfere with or prevent the activity and reproduction of pests. Examples include using traps, sticky boards, ultraviolet lamps, and nets to attract, capture, or isolate pests, thus reducing their damage to crops. Biological control uses natural enemy insects or microorganisms to control pest populations. Examples include releasing predatory natural enemies or using insecticidal microorganisms such as Bacillus thuringiensis and Beauveria bassiana to control pests.
[0003] The prior art discloses a method for controlling piercing-sucking pests by using ants to carry Beauveria bassiana. The method uses Beauveria bassiana as an insect pathogen and Japanese carpenter ants as carrier insects. The carrier insects are obtained by artificial breeding, and the insecticidal microorganisms carried by the ants are used to control pests.
[0004] When implementing the above technical solution, it is necessary to place the bacteria-carrying body at selected points in the field and then release artificially raised ants near the bacteria-carrying body. The ants' activity range and dwell time are greatly affected by the environment. If environmental conditions are unsuitable for ants to nest and settle, they will quickly migrate to other places to build nests and will not repeatedly pass through the bacteria-carrying body. Therefore, the ants only briefly pass through the bacteria-carrying body. First, due to the short contact time with the insecticidal microorganisms, the ants may not be able to carry enough microorganisms. In addition, the ants' activity paths and ranges are difficult to control, and the spread of microorganisms is not concentrated, all of which lead to less than ideal control effects. Second, once the ants leave the bacteria-carrying body, the effectiveness of using the insecticidal microorganisms carried by the ants to control pests will weaken over time, making it difficult to form a long-term and stable control effect. Utility Model Content
[0005] In view of the problem in the prior art that ants are prone to migration, making it difficult to form a long-term and stable control effect, this utility model provides a biological control device and its pest control system, which can form a long-term and stable control effect.
[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:
[0007] A biological control device includes a pipe, a first bacteria-carrying device, a nesting board, a light-shielding cover, and a tray. The pipe has an opening on its side wall. The first bacteria-carrying device is connected to one end of the pipe. The light-shielding cover, the nesting board, and the tray are all fitted onto and connected to the pipe. The light-shielding cover covers the tray, and the two form a movable cavity. The nesting board is located inside the movable cavity. The inner cavity of the pipe communicates with the movable cavity through the opening.
[0008] In use, the end of the pipe furthest from the first microbial-carrying device is inserted into the soil in the field, leaving the shading cover and the first microbial-carrying device exposed. The outlet end of the first microbial-carrying device is connected to the pest control platform. The pest control platform is a platform used in existing technologies to attract and trap pests over a large area in the field. Connecting the outlet end of the first microbial-carrying device to the pest control platform improves the efficiency of biological control. Because the shading cover and the tray form a relatively dark and concealed activity chamber, it simulates the shading and protection conditions of the natural environment. The nesting board provides a nesting site for ants, thus attracting ants from nature to enter the activity chamber through the opening in the pipe and then build their nests on the nesting board. Even in hot weather, ants will build insulation structures inside the activity chamber and will not easily abandon their nests. After settling in the activity chamber, when ants go out to hunt pests, collect nectar, or suck dew, they need to pass through the first microbial-carrying device at the pipe end, thus becoming contaminated with the insecticidal microorganisms on the device and inoculating and spreading them to the pest control platform.
[0009] By providing ants with stable and comfortable habitats and nesting sites, attracting them to build nests and settle down increases the frequency and duration of contact between ants and the primary microbial-carrying device. This allows for more effective carrying and dissemination of insecticidal microorganisms, improving the effectiveness and stability of biological control. Furthermore, since the pests on the control platform serve as a food source for the ants, it attracts both existing and non-existing ants, further increasing the spread rate of the insecticidal microorganisms. Simultaneously, the ants' consumption of pests on the control platform effectively cleans it, keeping the platform fresh and maintaining its stable pest-trapping capacity. The aforementioned device employs biological control, while the control platform utilizes physical control methods. When used in combination, they form a self-sustaining ecosystem requiring no human intervention, resulting in a more durable and stable biological control effect.
[0010] Preferably, the first microbial-carrying device includes a microbial-carrying ring, which is coaxially connected to one end of the pipe. The microbial-carrying ring is a ring-shaped structure carrying insecticidal microorganisms; it can be a non-woven fabric strip or a ring made of other materials that easily absorb microbial powder. The microbial-carrying ring ensures that ants carry a certain amount of insecticidal microorganisms each time they pass by, avoiding the problem of insufficient or uneven carrying of insecticidal microorganisms due to random contact with the first microbial-carrying device by ants.
[0011] Preferably, the first microbial-carrying device further includes a limiting ring coaxially connected to one end of the pipe. The inner ring of the limiting ring has a receiving groove, and the microbial-carrying ring is detachably installed in the receiving groove. The microbial-carrying ring is detachably connected to the pipe through the limiting ring, which allows workers to easily remove the microbial-carrying ring to replenish the insecticidal microorganisms or replace the microbial-carrying ring.
[0012] Preferably, the device further includes absorbent and moisturizing cotton, which is located inside the active cavity and at least partially contacts the inner wall of the light-shielding cover; the edge of the tray is provided with a first water-blocking part, and a first water-collecting trough is formed between the first water-blocking part and the outer wall of the light-shielding cover; the portion of the light-shielding cover in contact with the absorbent and moisturizing cotton is provided with multiple first water-permeable holes, and the first water-collecting trough communicates with the active cavity through the first water-permeable holes; the nesting board is provided with multiple first air-permeable holes, which allow air and water to pass through, keeping the humidity inside the active cavity uniform. The first water-collecting trough can collect and store rainwater, dew, and other water sources. The absorbent and moisturizing cotton can absorb water from the first water-collecting trough through the first water-permeable holes and maintain a certain humidity, thereby keeping the air inside the active cavity moist. The humid environment is closer to the natural environment, which can attract ants to enter the active cavity to build nests. During their stay in the active cavity, the ants will cover part of the area of the absorbent and moisturizing cotton to adjust the size of the area of the absorbent and moisturizing cotton exposed inside the active cavity, thereby meeting their own needs for environmental humidity.
[0013] Preferably, the system further includes a ventilator that passes through and connects to the tray. The ventilator has a first baffle and a second baffle at its two ends. The first baffle has multiple second vent holes, and the second baffle has multiple third vent holes. The second vent holes communicate with the active cavity. The first and second baffles prevent ants from leaving the active cavity through the ventilator instead of the pipe. Outside air can enter the ventilator through the third vent holes and then enter the active cavity through the second vent holes. The ventilator increases the permeability of the active cavity. Appropriate permeability prevents the growth of mold or other harmful microorganisms due to excessive humidity, thus providing more suitable living conditions for the ants. Furthermore, appropriate permeability helps the germination and survival of insecticidal microorganisms carried by the ants in the active cavity, improving the effectiveness of biological control.
[0014] Preferably, at least two nesting boards are provided and spaced apart along the axial direction of the pipe, with each nesting board located between the top and bottom of the opening. Providing at least two nesting boards helps ants make full use of space to construct complex internal nests.
[0015] Preferably, the device further includes a buried cover and a water collection ring. The top of the buried cover is connected to the end of the pipe furthest from the first bacteria-carrying device. The buried cover has multiple second permeable holes. The water collection ring is connected to the edge of the buried cover and has a second water collection trough, which communicates with the inner cavity of the buried cover. In use, the buried cover is buried in the soil. Water in the soil can seep into the inner wall of the buried cover through the second permeable holes. The water on the inner wall of the buried cover then flows into the second water collection trough and accumulates. After evaporation, the water in the second water collection trough enters the active cavity through the inner cavity of the pipe and the opening. The buried cover collects water from the soil into the second water collection trough, and the water in the second water collection trough evaporates to replenish the active cavity. This reduces the dependence on the water source of the first water collection trough and buffers the impact of the water volume of the first water collection trough on the humidity inside the active cavity. Ants will add or remove nesting materials at the opening according to the required humidity, thereby adjusting the opening size of the opening to keep the humidity inside the active cavity within a suitable range.
[0016] Preferably, the inner wall of the buried cover is spherical. The spherical structure allows water to flow into the second water collection tank more quickly and smoothly, reducing water residue on the inner wall of the buried cover.
[0017] Preferably, the pipe is provided with a telescopic section, which is located between the light-shielding cover and the buried cover. The telescopic section can be a multi-jointed telescopic pipe or a corrugated telescopic flexible hose. The telescopic section allows for adjustment of the distance between the buried cover and the tray, facilitating adjustment of the buried cover's burial depth and meeting the usage requirements under different soil and environmental conditions.
[0018] Preferably, a second microbial-carrying device is connected to the outside of the pipe, located between the tray and the buried cover. Ants that venture outside the pipe may pick up insecticidal microorganisms through the second microbial-carrying device, then inoculate and spread the microorganisms to the field. Ants attracted from the field to the pest control platform will also bring the insecticidal microorganisms from the field to the platform to reproduce. This not only expands the pest control range but also allows for long-term, natural implementation of "using insects to control insects" and "using microorganisms to control insects." Therefore, setting up a second microbial-carrying device helps improve the spread efficiency of insecticidal microorganisms and enhances the control effect.
[0019] This invention also provides a pest control system, including an insect-attracting component, a pest-control platform, and the aforementioned biological control device. The insect-attracting component is disposed on the pest-control platform, and the outlet end of the first bacteria-carrying device is connected to the pest-control platform. The insect-attracting component is used to induce pests to gather within the component and on the platform; it can be an insect trap, an insect-attracting lamp, or a chemical trapping component containing plant volatiles, etc. Combining the biological control device with the pest-control platform can reduce large-scale pest control to small-scale pest control. This pest control method, which expands from a broad area to a specific point and then back again, is highly efficient, environmentally friendly, and significantly reduces control costs. Other principles and effects of this system have been explained above and will not be repeated here.
[0020] The beneficial effects of this utility model are:
[0021] 1. By providing ants with stable and comfortable habitats and nesting sites, ants in nature can be attracted to build nests and settle in the activity cavity. This increases the frequency and duration of contact between ants and the primary bacteria-carrying device, thereby more effectively carrying and spreading insecticidal microorganisms, improving the effectiveness and stability of biological control, and forming a long-term and stable control effect.
[0022] 2. Combining three green pest control methods—microbial control, physical control, and insect-based pest control—can create a self-sustaining ecosystem. The pests on the control platform serve as a food source for ants, attracting both existing and non-existing ants to gather there, thus further increasing the spread of insecticidal microorganisms. When ants consume the pests on the control platform, it effectively cleans the platform, ensuring its long-term freshness and stable pest-trapping capacity. The entire system achieves continuous and stable pest control without human intervention.
[0023] 3. The insect-attracting components can concentrate a large number of pests inside the components and on the control platform. When ants crawl onto the components and platforms to prey on pests, they come into contact with and carry the insecticidal microorganisms on the components and platforms, subsequently spreading the microorganisms to a wider area, triggering an "insect plague" effect. This effect continuously cycles through the interaction between pests and ants, ultimately forming an ecological balance. This pest control method, from surface to point and then from point to surface, not only achieves long-term effective pest control goals but is also highly efficient and environmentally friendly, significantly reducing control costs.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.
[0032] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:
[0033] Example 1
[0034] This embodiment is a first embodiment of a biological control device, combined with... Figure 1 and Figure 2As shown, it includes a pipe 1, a first bacteria-carrying device 2, a nesting board 3, a light-shielding cover 4, and a tray 5. The side wall of the pipe 1 is provided with an opening 101. The first bacteria-carrying device 2 is connected to one end of the pipe 1. The light-shielding cover 4, the nesting board 3, and the tray 5 are all fitted onto the pipe 1 and connected to the pipe 1. The light-shielding cover 4 covers the tray 5, and the two form a movable cavity 401 between them. The nesting board 3 is located inside the movable cavity 401. The inner cavity of the pipe 1 is connected to the movable cavity 401 through the opening 101.
[0035] The nesting board 3 can be a flat plate structure or an uneven plate structure. In this embodiment, the longitudinal section of the nesting board 3 is zigzag-shaped. In the natural environment, ant nests usually have complex structures, including multiple passages and rooms. The zigzag-shaped longitudinal section of the nesting board 3 can form multiple small spaces or corners, allowing the nesting board 3 to provide more activity areas within a limited volume, providing more functional partitions for ants, and simulating a more suitable natural environment for ants to live in.
[0036] Furthermore, the top end of the pipe 1 is provided with a bend 103, the axis of which is perpendicular to the axis of the pipe 1; the first bacteria-carrying device 2 is connected to the end of the bend 103. The horizontal bend 103 facilitates the docking of the first bacteria-carrying device 2 with the external pest control platform 14.
[0037] Furthermore, the first microbial-carrying device 2 includes a microbial-carrying ring 203, the inner diameter of which is larger than the inner diameter of the pipe 1, and the microbial-carrying ring 203 is coaxially connected to one end of the pipe 1. The microbial-carrying ring 203 is a ring-shaped structure carrying insecticidal microorganisms, and it can be a ring made of non-woven fabric or other materials that easily absorb microbial powder. The microbial-carrying ring 203 ensures that ants carry a certain amount of insecticidal microorganisms each time they pass by, avoiding the problem of insufficient or uneven carrying of insecticidal microorganisms due to random contact of ants with the first microbial-carrying device 2.
[0038] Furthermore, the first microbial-carrying device 2 also includes a limiting ring 201 coaxially connected to one end of the pipe 1. The inner ring of the limiting ring 201 is provided with a receiving ring groove 202, and the microbial-carrying ring 203 is detachably installed in the receiving ring groove 202. The microbial-carrying ring 203 is detachably connected to the pipe 1 through the limiting ring 201, which makes it convenient for staff to remove the microbial-carrying ring 203 to replenish the insecticidal microorganisms or replace the microbial-carrying ring 203.
[0039] The working principle or workflow of this embodiment: combined with Figures 1 to 3As shown, in use, the end of pipe 1 furthest from the first bacteria-carrying device 2 is inserted into the soil in the field, leaving the shading cover 4 and the first bacteria-carrying device 2 exposed. The outlet end of the first bacteria-carrying device 2 is connected to the pest control platform 14. The pest control platform 14 is a platform used in the prior art to attract and trap pests over a large area in the field. Connecting the outlet end of the first bacteria-carrying device 2 to the pest control platform 14 can improve the efficiency of biological control. Since the shading cover 4 and the tray 5 form a relatively dark and concealed activity cavity 401, it can simulate the shading and protection conditions in the natural environment. The nesting board 3 can provide a nesting site for ants, thus attracting ants from nature to enter the activity cavity 401 through the opening 101 on pipe 1 and then build nests on the nesting board 3. Even in hot weather, ants will build insulation structures inside the activity cavity 401 and will not easily abandon their nests. After the ants settle in the activity chamber 401, when they go out to hunt pests, collect nectar, and suck dew, they need to pass through the first bacteria-carrying device 2 at the port of the pipe 1. As a result, they will be contaminated with insecticidal microorganisms on the first bacteria-carrying device 2 and will inoculate and spread the insecticidal microorganisms to the pest control platform 14.
[0040] The beneficial effects of this embodiment:
[0041] 1. By providing ants with stable and comfortable habitats and nesting sites, ants in nature can be attracted to build nests and settle in the activity cavity. This increases the frequency and duration of contact between ants and the primary bacteria-carrying device, thereby more effectively carrying and spreading insecticidal microorganisms, improving the effectiveness and stability of biological control, and forming a long-term and stable control effect.
[0042] Example 2
[0043] This embodiment is a second embodiment of a biological control device. This embodiment is similar to Embodiment 1, except that it combines... Figures 1 to 5As shown, it also includes a water-absorbing and moisturizing cotton 6, which is located inside the active cavity 401 and at least partially contacts the inner wall of the light-shielding cover 4; the edge of the tray 5 is provided with a first water-blocking part 501, and a first water-collecting trough 502 is formed between the first water-blocking part 501 and the outer wall of the light-shielding cover 4; the part of the light-shielding cover 4 that contacts the water-absorbing and moisturizing cotton 6 is provided with multiple first water-permeable holes (not shown in the figure), and the first water-collecting trough 502 is connected to the active cavity 401 through the first water-permeable holes; the nesting board 3 is provided with multiple first air-permeable holes, which can allow air and water to pass through, so that the humidity inside the active cavity 401 is kept uniform. The first water-collecting trough 502 can collect and store rainwater, dew and other water sources, and the water-absorbing and moisturizing cotton 6 can absorb water from the first water-collecting trough 502 through the first water-permeable holes and maintain a certain humidity, thereby keeping the air inside the active cavity 401 moist. The moist environment is closer to the natural environment, which can attract ants to enter the active cavity 401 to build nests. During their stay in the activity chamber 401, ants will cover part of the area of the absorbent and moisturizing cotton 6 to adjust the size of the area of the absorbent and moisturizing cotton 6 exposed in the activity chamber 401, thereby meeting their own needs for environmental humidity.
[0044] Furthermore, it also includes a ventilation cylinder 7, which passes through and connects to the tray 5. The ventilation cylinder 7 has a first baffle 8 and a second baffle 9 at its two ends, respectively. The first baffle 8 has multiple second ventilation holes 801, and the second baffle 9 has multiple third ventilation holes 901. The second ventilation holes 801 communicate with the active cavity 401. The first baffle 8 and the second baffle 9 can block ants, preventing them from leaving the active cavity 401 through the ventilation cylinder 7 instead of the pipe 1. Outside air can enter the ventilation cylinder 7 through the third ventilation holes 901 and then enter the active cavity 401 through the second ventilation holes 801. The ventilation cylinder 7 increases the permeability of the active cavity 401. Appropriate permeability can prevent the growth of mold or other harmful microorganisms due to excessive humidity in the active cavity 401, thus providing more suitable living conditions for ants. Moreover, appropriate permeability helps the germination and survival of insecticidal microorganisms carried by ants in the active cavity 401, which is beneficial to improving the effectiveness of biological control.
[0045] Furthermore, two nesting boards 3 are provided and spaced apart along the axis of the pipe 1, with each nesting board 3 located between the top and bottom of the opening 101. Providing two nesting boards 3 helps ants fully utilize space for complex internal nest construction. The edges of the nesting boards 3 can either be completely flush with the inner wall of the light-shielding cover 4 or maintain a certain distance from it. In this embodiment, the outer edge of the nesting board 3 is completely flush with the inner wall of the light-shielding cover 4.
[0046] Furthermore, it also includes a buried cover 10 and a water collection ring 11. The top of the buried cover 10 is connected to the end of the pipe 1 away from the first bacteria-carrying device 2. The buried cover 10 is provided with multiple second water-permeable holes (not shown in the figure). The water collection ring 11 is connected to the edge of the buried cover 10 and is provided with a second water collection trough 1101, which is connected to the inner cavity of the buried cover 10. In use, the buried cover 10 is buried in the soil. Water in the soil can seep into the inner wall of the buried cover 10 through the second water-permeable holes. The water on the inner wall of the buried cover 10 then flows into the second water collection trough 1101 and collects. After the water in the second water collection trough 1101 evaporates, it enters the active cavity 401 through the inner cavity of the pipe 1 and the opening 101. The buried cover 10 can collect water in the soil into the second water collection trough 1101, and the water in the second water collection trough 1101 evaporates again to replenish the active inner cavity. This reduces reliance on the water source of the first water collection tank 502 and buffers the impact of the water volume in the first water collection tank 502 on the humidity inside the activity cavity 401. The ants will replenish or remove nesting materials at the opening 101 according to the required humidity, thereby adjusting the opening size of the opening 101 to keep the humidity inside the activity cavity 401 within a suitable range.
[0047] Furthermore, the inner wall of the buried cover 10 is spherical. The spherical structure allows water to flow into the second water collection tank 1101 more quickly and smoothly, reducing water residue on the inner wall of the buried cover 10.
[0048] Furthermore, the pipe 1 is equipped with a telescopic section 102, which is located between the light-shielding cover 4 and the buried cover 10. Specifically, the telescopic section 102 is a corrugated telescopic hose. The corrugated telescopic hose can extend and retract in the vertical direction and bend in the horizontal direction. The telescopic section 102 allows for adjustment of the distance between the buried cover 10 and the tray 5, facilitating adjustment of the burial depth and burial position of the buried cover 10 to meet the usage requirements under different soil and environmental conditions.
[0049] Furthermore, a second microbial-carrying device 12 is connected to the outside of pipe 1. The second microbial-carrying device 12 is located between tray 5 and the buried cover 10. The structure of the second microbial-carrying device 12 is the same as that of the first microbial-carrying device 2. Ants that venture outside pipe 1 may become infected with insecticidal microorganisms through the second microbial-carrying device 12, and then inoculate and spread the insecticidal microorganisms to the field. Ants attracted from the field to the pest control platform will also bring the insecticidal microorganisms from the field to the pest control platform to reproduce. This not only expands the pest control range but also allows for the long-term natural implementation of "using insects to control insects" and "using microorganisms to control insects." Therefore, setting up the second microbial-carrying device 12 is beneficial to improving the spread efficiency of insecticidal microorganisms and enhancing the control effect.
[0050] Other features, working principles, and beneficial effects of this embodiment are the same as those of Embodiment 1.
[0051] Example 3
[0052] This embodiment is a first embodiment of a pest control system. This embodiment is similar to Embodiment 2, except that, as shown in the example... Figure 3 As shown, it includes an insect-attracting component 13, an insect-control platform 14, and the biological control device described in Example 2. The insect-attracting component 13 is disposed on the insect-control platform 14, and the outlet end of the first bacteria-carrying device 2 is connected to the insect-control platform 14. The insect-attracting component 13 can be an insect trap, an insect-attracting lamp, a chemical trapping component containing plant volatiles, etc. Both the insect-attracting component 13 and the insect-control platform 14 are prior art, therefore their specific structures will not be described in detail.
[0053] The beneficial effects of this embodiment:
[0054] 1. Combining three green pest control methods—microbial control, physical control, and insect-based pest control—can create a self-sustaining ecosystem. The pests on the control platform serve as a food source for ants, attracting both existing and non-existing ants to gather there, thus further increasing the spread of insecticidal microorganisms. When ants consume the pests on the control platform, it effectively cleans the platform, ensuring its long-term freshness and stable pest-trapping capacity. The entire system achieves continuous and stable pest control without human intervention.
[0055] 2. The insect-attracting device can concentrate a large number of pests inside the device and on the control platform. When ants crawl onto the device and platform to prey on the pests, they come into contact with and carry the insecticidal microorganisms on the device and platform, subsequently spreading these microorganisms to a wider area, triggering an "insect plague" effect. This effect continuously cycles through the interaction between pests and ants, ultimately forming an ecological balance. This pest control method, from surface to point and then from point to surface, not only achieves long-term effective pest control goals but is also highly efficient and environmentally friendly, significantly reducing control costs.
