Description

Technical Field

[0001] This invention relates to the field of agricultural pest trapping technology, and in particular to an outdoor device for efficiently trapping the oriental fruit fly and its method of use. Background Technology

[0002] In the field of green pest control in agriculture, the use of trapping devices combining sex pheromones (sex attractants) and food sources (fruits) is an environmentally friendly and highly specific physical control method for fruit flies such as the oriental fruit fly, which are highly diffusive and harmful. These devices, suspended in the field, simulate the wild aggregation and feeding environment of the oriental fruit fly, effectively monitoring insect population density and directly trapping and killing adult flies. This reduces the use of chemical pesticides and is of great significance for ensuring fruit and vegetable yield and quality, and maintaining ecological balance.

[0003] However, the effectiveness and convenience of existing outdoor trapping devices still face significant limitations in practical promotion and application. Firstly, the diffusion efficiency of the scent emitted by the lure and fruit directly determines the trapping radius and effectiveness of the device. Traditional devices often rely on a single inlet or simple ventilation holes, resulting in a limited scent diffusion area and rapid dissipation due to wind and rain, leading to a small effective range and unstable trapping efficiency. Secondly, the design of the path for pests to enter the device is also crucial. Too few inlets or an unreasonable structure will limit the probability of pests being detected and entering; and once pests enter, if the confinement structure is flawed, they can easily escape, significantly reducing the trapping effect. Furthermore, many existing devices are complex in structure and have numerous components. Deployment in the field, bait replacement, pest control, and daily maintenance often require considerable manpower and time. Assembly and disassembly are inconvenient, and long-term operability and economic efficiency are insufficient, affecting farmers' enthusiasm for use and the feasibility of large-scale promotion.

[0004] Therefore, how to develop an outdoor fruit fly trapping device that can more effectively diffuse pheromones and fruit odors, provide more and more reasonable entry channels to improve pest entry efficiency, and ensure that the device itself is simple in structure, easy to assemble and maintain, so as to achieve labor-saving, efficient and long-lasting trapping in the field has become a practical problem that needs to be solved in this field. Summary of the Invention

[0005] The purpose of this invention is to provide an outdoor device for efficiently attracting citrus fruit flies and its method of use, which can more effectively diffuse pheromones and fruit odors, provide more and more reasonable entry channels to improve pest entry efficiency, and ensure that the device itself has a simple structure, is easy to assemble and maintain, thereby achieving labor-saving, efficient and long-lasting attraction in the field.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This invention discloses an outdoor high-efficiency device for attracting oriental fruit flies, comprising a sunshade and rain cover, a cubic inlay, a rectangular attractant bottle, a round rod, and a shelf. The sunshade and rain cover has a hemispherical structure at its top, with a horizontally penetrating hanging hole. A circular fixing hole is located at the top interior of the sunshade and rain cover, and the upper end of the round rod is fixedly connected to this hole. The cubic inlay is positioned below the sunshade and rain cover, with a hole at its center for the round rod to pass through. The lower end of the round rod passes through the cubic inlay and extends downwards. The cylindrical rod has an axial protrusion for vertically limiting the cube-shaped inlay. The shelf is suspended from the lower end of the cylindrical rod. Each axial side of the cube-shaped inlay has at least one insect inlet channel. The top of the cube-shaped inlay has a vertical, through-hole circular insect inlet corresponding to each insect inlet channel. The insect inlet is connected to its corresponding insect inlet channel. The cuboid attractant bottle is connected to the bottom of the cube-shaped inlay. One side of the bottle has a nylon mesh seal for emitting odor, and the opposite side has an openable bottle door.

[0007] Preferably, the cube-shaped inlay and the cuboid trap bottle are connected by a snap-fit ​​connection.

[0008] Preferably, each axial side of the cube inlay is provided with two insect inlet channels, the insect inlet channels are J-shaped, and the hook ends of the channels are connected to the insect inlet.

[0009] Preferably, the shelf has an n-shaped structure, with its top back end connected to the round rod, and its bottom back end having a bait box for placing pheromones or fruit.

[0010] Preferably, the open side of the shelf is slidably connected to an adjustable counterweight assembly, the counterweight assembly including a connecting block slidably connected to the shelf, an F-shaped mounting bracket disposed on the connecting block, an adjusting bolt threadedly connected to the F-shaped mounting bracket for locking the connecting block on the shelf, and a replaceable counterweight block sleeved on the adjusting bolt.

[0011] Preferably, the bottle door is provided with a door handle.

[0012] Preferably, the nylon mesh sealing has a mesh count of 200.

[0013] Preferably, the circular rod and the circular fixing hole are connected by an interference fit or a threaded connection.

[0014] Preferably, the sunshade and rain cover has a dome-shaped structure.

[0015] A method for using an outdoor high-efficiency attractor for oriental fruit flies includes the following steps: S1. Pass the suspension rope through the suspension hole and suspend the entire device on an outdoor support using the suspension rope; S2. Place pheromone and fresh fruit in the bait box, and keep the shelf horizontally balanced by adjusting the vertical position of the counterweight assembly or the weight of the counterweight block. S3. The oriental fruit fly is attracted by the odor and enters through the insect inlet. Guided by the insect inlet channel, it eventually falls into the rectangular trap bottle and is blocked by the nylon mesh seal, preventing it from escaping. S4. Periodically open the bottle door to clean or count the oriental fruit flies collected in the rectangular trap bottle.

[0016] Compared with the prior art, the device provided by the present invention has the following beneficial effects: This invention features a nylon mesh seal on one side of the rectangular trap bottle, effectively increasing the area and efficiency of the diffusion of the pheromone and fruit scent from the bottle, allowing the insect-attracting information to spread over longer distances in the field. Simultaneously, interconnected circular insect-entry openings and channels are provided on the top and sides of the cubic inlay. This multi-directional, multi-entry structure not only provides more entry paths for the oriental fruit fly, significantly increasing the probability of the pest discovering and entering the device, but the channels themselves also constitute auxiliary scent diffusion channels, further enhancing the overall attraction range and achieving higher trapping efficiency. The device of this invention is designed with ease of use and reliability in mind. The sunshade and rain cover, the cubic insert, and the rectangular bait bottle are primarily connected using simple methods such as plug-in and snap-fit, making assembly and disassembly quick and easy. The shelf is suspended via snap-fit ​​and equipped with an adjustable counterweight to easily balance the bait weight and maintain device stability. The bottle has an openable door for easy periodic pest removal and bait replacement. These design features greatly simplify deployment and maintenance, requiring no special tools or complex operations, significantly reducing reliance on manpower and maintenance time costs.

[0017] In summary, this invention combines an optimized odor diffusion system, an efficient insect entry channel, and a convenient modular structure to create a stable, efficient, and labor-saving trapping environment for the oriental fruit fly. This device can not only operate reliably and for extended periods under various outdoor climatic conditions, effectively reducing the insect population density in the target area, but its simple maintenance also makes it suitable for large-scale application in orchards, providing a practical physical control tool for the green control of the oriental fruit fly.

[0021] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] like Figure 1-4 As shown, an outdoor high-efficiency device for attracting oriental fruit flies includes a sunshade and rain cover 1, a cubic inlay 6, a rectangular attractant bottle 13, a round rod 5, and a shelf 10. The top of the sunshade and rain cover 1 has a hemispherical structure 2 with a horizontally penetrating hanging hole 3. A circular fixing hole 4 is located at the top interior of the sunshade and rain cover 1. The upper end of the round rod 5 is fixedly connected to the circular fixing hole 4. The cubic inlay 6 is located below the sunshade and rain cover 1, and its center has a rod hole 9 for the round rod 5 to pass through. The lower end of the round rod 5 passes through the cubic inlay 6 and extends downwards. Furthermore, the round rod 5 is provided with an axial protrusion for vertically limiting the cube inlay 6. The shelf 10 is suspended and connected to the lower end of the round rod 5. Each axial side of the cube inlay 6 is provided with at least one insect inlet channel 7. The top of the cube inlay 6 is provided with a vertical and through circular insect inlet 8 corresponding to the position of each insect inlet channel 7. The insect inlet 8 is connected to its corresponding insect inlet channel 7. The cuboid attractant bottle 13 is connected to the lower part of the cube inlay 6. One side of the bottle is provided with a nylon mesh seal 14 for emitting odor, and the opposite side is provided with an openable bottle door 15.

[0023] Specifically, the present invention mainly comprises five parts: a sunshade and rain cover 1, a cubic inlay 6, a cuboid attractant bottle 13, a round rod 5, and a shelf 10. The hemispherical structure 2 at the top of the sunshade and rain cover 1 has a hanging hole 3, facilitating the threading of a rope to suspend the entire device on outdoor supports such as tree branches. The upper end of the round rod 5 is securely inserted into a circular fixing hole 4 inside the sunshade and rain cover 1, forming the core support shaft of the device. The cubic inlay 6 is fitted onto the round rod 5, and is vertically limited by an axial protrusion on the round rod 5 to prevent slippage. The shelf 10 is suspended from the bottom end of the round rod 5.

[0024] Specifically, the top surface of the cube-shaped inlay 6 has multiple circular insect inlets 8, each connected to an insect entry channel 7 extending from its side. This structural design allows oriental fruit flies to enter not only through the circular inlets 8 at the top but also by converging at the inlets 8 through the side entry channels 7, ultimately falling into the rectangular trap bottle 13 below, thus improving the convenience and efficiency of pest entry. Simultaneously, the increased number of entry channels 7 also facilitates the diffusion of the bait's scent, enhancing the trapping range.

[0025] Specifically, the rectangular trap bottle 13 is connected to the bottom of the cubic inlay 6. A nylon mesh seal 14 on one side allows odors to pass through and prevents pests from escaping, while an openable door 15 on the other side facilitates the removal of captured pests. The device has a compact overall structure, is easy to assemble and use, and can achieve efficient and continuous trapping of oriental fruit flies without complicated operation or a large amount of manpower for maintenance.

[0026] Specifically, the cube inlay 6 and the cuboid trap bottle 13 are connected by a snap-fit ​​connection.

[0027] Specifically, a hook is provided on the bottom edge of the cube-shaped inlay 6, and a slot is provided at the corresponding position of the mouth of the cuboid trap 13. The two can be quickly engaged and disengaged by rotating or pressing. This connection method facilitates the disassembly and installation of the cuboid trap 13. Users can periodically remove the cuboid trap 13 to clean, count, or replace damaged parts, greatly simplifying maintenance work.

[0028] Specifically, each axial side of the cube inlay 6 is provided with two insect inlet channels 7, which are J-shaped and whose hook ends are connected to the insect inlet 8.

[0029] Specifically, each side of the cube-shaped inlay 6 is machined with two J-shaped insect entry channels 7. The horizontal entrance of the J-shaped channel is located on the side, and its hook-shaped end extends inward and connects to the circular insect entry port 8 at the top of the cube-shaped inlay 6. This structural design allows the oriental fruit fly to enter through the entrance of the side insect entry channel 7, climb or fly upward along the J-shaped path, and finally fall into the rectangular trap bottle 13 below through the insect entry port 8 at the top. The curved path of the J-shape effectively prevents pests that have entered the bottle from easily finding themselves against the light or airflow and escaping along the original path, thereby improving the trapping effect after trapping, while not affecting the entry of external pests into the device from all directions by being attracted by the scent.

[0030] Specifically, the shelf 10 has an n-shaped structure, with its top back connected to the round rod 5, and its bottom back has a bait box 11 for placing pheromones or fruit.

[0031] Specifically, the top of the back of the shelf 10 is provided with a slot that matches the shape of the lower end of the round rod 5, and the bottom end of the round rod 5 is provided with a second axial protrusion for engaging the shelf 10.

[0032] Specifically, the open side of the shelf 10 is slidably connected to an adjustable counterweight assembly. The counterweight assembly includes a connecting block slidably connected to the shelf 10, an F-shaped mounting bracket disposed on the connecting block, an adjusting bolt 12 threadedly connected to the F-shaped mounting bracket for locking the connecting block onto the shelf 10, and a replaceable counterweight block sleeved on the adjusting bolt 12.

[0033] Specifically, when the adjusting bolt 12 is loosened, the entire connecting block can move up and down along the groove opened on the shelf 10; when the adjusting bolt 12 is tightened, its end will press against the shelf 10, thereby locking the connecting block at the desired height. One or more replaceable counterweights are also fitted on the adjusting bolt 12. By adjusting the height of the connecting block or replacing the counterweights with different weights, the weight of the bait box 11 on the other side and the bait placed inside can be balanced, ensuring that the shelf 10 remains horizontal when suspended, and preventing the bait from slipping or the entire device from becoming unbalanced and wobbling due to tilting.

[0034] Specifically, the bottle door 15 is equipped with a door handle.

[0035] Specifically, the nylon mesh sealing 14 has a mesh count of 200.

[0036] Specifically, the round rod 5 and the circular fixing hole 4 are either interference fit or threaded connection.

[0037] Specifically, the sunshade and rain cover 1 has a dome-shaped structure.

[0038] Specifically, this streamlined dome structure has excellent rain-guiding properties; rainwater falls onto the cover and slides off without accumulating at the top. Simultaneously, the raised dome structure creates a shaded area below, providing shade for the interior of the device and the vicinity of the insect inlet 8. This prevents direct sunlight from causing the pheromone in the bait box 11 to evaporate and become ineffective too quickly, or for fresh fruit to dry out and rot rapidly. It also provides a relatively cool environment for pests when they approach, which is more in line with their habits and helps improve the trapping efficiency.

[0039] A method for using an outdoor high-efficiency attractor for oriental fruit flies includes the following steps: S1. Pass the suspension rope through the suspension hole 3, and suspend the entire device on an outdoor support using the suspension rope; S2. Place pheromone and fresh fruit in the bait box 11, and keep the shelf 10 horizontally balanced by adjusting the vertical position of the counterweight assembly or the weight of the counterweight block. S3. The oriental fruit fly is attracted by the smell and enters through the insect inlet 8. It is guided by the insect inlet channel 7 and finally falls into the rectangular trap bottle 13. It is blocked by the nylon net seal 14 and cannot escape. S4. Periodically open the bottle door 15 to clean or count the oriental fruit flies collected in the rectangular trap bottle 13.
