Description

Technical Field

[0001] This invention relates to traps, particularly to traps for the fourth instar nymphs of the bamboo oval bug. It also relates to attractants and repellents, particularly to attractants and repellents for the fourth instar nymphs of the bamboo oval bug, and to methods of application, specifically the traps for the fourth instar nymphs of the bamboo oval bug and the methods of applying the attractants and repellents. This invention belongs to the field of forest conservation technology. Background Technology

[0002] The bamboo oval bug (Hippotiscus dorsalis) belongs to the family Pentatomidae in the order Hemiptera. It mainly damages economically important bamboo species such as moso bamboo, skeletal bamboo, and light bamboo. The bamboo oval bug overwinters as 3rd-4th instar nymphs. In March and April of the following year, the fourth instar nymphs first climb onto the bamboo to feed. Exploring control techniques for the fourth instar nymphs can reduce the damage to moso bamboo from the source. Currently, the main control methods for the fourth instar nymphs are: during the peak period of bamboo oval bug nymph infestation in April and May, use grooved traps to kill the nymphs; before the fourth instar nymphs climb the bamboo, use a mixture of butter and machine oil to make a sticky insecticide, and apply a closed oil ring around the base of the bamboo culm to prevent the nymphs from climbing the bamboo; chemical control, using various chemical agents through spraying, dusting, or ring-like poisoning to reduce the insect population density.

[0003] The above methods also have many drawbacks in the control of bamboo oval bugs. Using insect traps consumes a lot of manpower and is labor-intensive; using sticky insecticides requires operating on all bamboo in the bamboo forest, which is labor-intensive, and grease, machine oil, etc. can easily cause environmental pollution; chemical reagent control can easily cause environmental pollution.

[0004] To address these issues, a trap for fourth-instar nymphs of the bamboo oval bug, along with an attractant and repellent agent and its application method, were designed. Summary of the Invention

[0005] The main objective of this invention is to provide a trap for the fourth instar nymphs of the bamboo oval bug, along with an attractant and repellent agent and a method of application. The trap involves inserting a stake into a bamboo forest and placing a slow-release bottle filled with an attractant on a socket at the top of the stake. This attracts the nymphs, and the trap is then combined with sticky traps arranged in a cross shape along the side of the stake. This method effectively captures the nymphs, avoiding the environmental pollution caused by chemical control and the excessive manpower required for physical control. Furthermore, placing the slow-release bottle containing the repellent between adjacent devices utilizes the synergy between the attractant and repellent, improving trapping efficiency. A mounting plate is rotatably mounted at the top of the stake, with horizontal plates evenly installed along its sides. A vertical plate is hinged to the bottom of each horizontal plate, fixing the sticky traps between them. Under wind pressure, the sticky traps rotate around the stake, resulting in more even adhesion of the insects. The rotation of the sticky traps further enhances the trapping efficiency. The rotation also accelerates the release of the attractant, resulting in better effectiveness. With an upper partition between the tops of multiple horizontal plates and a lower partition between the bottoms of the vertical plates, along with retractable side partitions inside the vertical plates, the device effectively prevents fallen leaves from sticking to the insect trap during use, ensuring effective insect trapping. The insert rod contains an installation cavity, a lower L-shaped rod, a positioning hole, a lower spring, a through hole, an upper L-shaped rod, and an upper spring. Combined with the insert block at the end of the horizontal rod, the device automatically controls the opening of the slow-release bottle and releases the locking between the bottom of the insert rod and the cone head when unfolded, ensuring the insect trap can rotate during use. When folded, the device automatically closes the slow-release bottle and locks the cone head in place, facilitating rotation, removal, and movement. The device is more convenient to unfold and use, and its practicality is enhanced.

A spring is installed at each end of the take-up bar. The inner end of the spring is fixedly connected to the take-up bar, and the outer end of the spring is fixedly connected to the inner end of the storage slot. A side mesh is wound and installed on the take-up bar. A strip-shaped opening is opened on the side of the vertical rod for the side mesh to pass through. A third hook is installed at the outer end of the side mesh. A hanging ring that cooperates with the third hook is provided on the outer side of the vertical rod.

[0012] Preferably, a scraper that fits against the outside of the diffusion sponge is vertically fixed to the bottom of the mounting plate, and a conical cover is fixed to the outside of the insertion rod and inside the receiving sleeve.

[0013] Preferably, the top of the socket has a receiving groove, the bottom of the slow-release bottle is inserted into the receiving groove, the bottom of the slow-release bottle has evenly spaced leakage holes, the bottom of the plug rod has an installation cavity, the side of the installation cavity has evenly spaced through holes, the inside of each through hole has a sliding plug, the plug is fixed to the bottom of the inside of the crossbar, the top of the plug rod has an evenly spaced vertically sliding upper L-shaped rod, the bottom of the upper L-shaped rod extends into the inside of the installation cavity, the bottom of the upper L-shaped rod and the top of the installation cavity are both provided with upper springs, the top of the upper L-shaped rod extends into the receiving groove, and the top of the upper L-shaped rod is respectively attached to the bottom of the leakage holes.

[0014] Preferably, a cone head is rotatably mounted at the bottom end of the insertion rod, and a spiral blade is provided on the outer side of the cone head. A lower L-shaped rod is uniformly and vertically slidably mounted inside the insertion rod. The top end of the lower L-shaped rod is located inside the mounting cavity, and the bottom end of the lower L-shaped rod extends to the bottom of the insertion rod. A lower spring is provided between the top end of the lower L-shaped rod and the bottom of the mounting cavity. A positioning insertion hole that mates with the lower L-shaped rod is opened at the top of the cone head.

[0015] This invention also provides a formulation for an attractant and repellent agent for the fourth instar nymph of the bamboo oval bug, comprising the following formulation components and their proportions:

[0016] The attractant formulation includes nonanal, hexanal, phenylacetaldehyde, and hexane in a weight ratio of (1-2):(1-2):(20-30):(1000 minus the sum of the weights of nonanal, hexanal, and phenylacetaldehyde).

[0017] The repellent formulation includes caryophyllene, camphor, β-pinene, and hexane in a weight ratio of (25-100): (1-100): (25-100): (1000 minus the sum of the proportions of caryophyllene, camphor, and L-β-pinene).

[0018] The present invention also provides a trap for fourth instar nymphs of the bamboo oval bug and a method for applying the attractant and repellent, comprising the following steps:

[0019] Step 1: First, fill the inside of the slow-release bottle with the attractant, then insert the bottom of the slow-release bottle into the receiving slot on the socket. The leak hole at the bottom of the slow-release bottle is blocked by the upper L-shaped rod, and the bottom of the slow-release bottle is in a sealed state.

[0020] Step 2: Move the stake to the designated position, then insert the stake vertically into the ground, with the cone head fully inserted into the ground;

[0021] Step 3: Pull the insert at the bottom of the crossbar out of the mounting cavity to release the seal on the slow-release bottle and the locking state of the cone. The lower L-shaped rod and the upper L-shaped rod are reset by the elastic force of the lower spring and the upper spring. The attractant inside the slow-release bottle is released and drips into the diffusion sponge to evaporate outward. The reset of the lower L-shaped rod releases the locking state between the insert and the cone, and the insert can rotate on the ground.

[0022] Step 4: Unfold the horizontal bar horizontally, cover the top of the horizontal bar with the upper partition net, then flip the vertical bar downwards to be vertical, cover the bottom of the vertical bar with the lower partition net, then suspend the sticky insect board between the inside of the horizontal bar and the inside of the vertical bar, finally pull the side partition net out from the inside of the vertical bar, and hang the third hook at the end of the vertical bar on the hanging ring. The upper partition net, lower partition net and side partition net provide external protection for the sticky insect board;

[0023] Step 5: After the poles are interlocked, fix the slow-release bottle containing the repellent directly onto the bamboo pole in the forest, 0.5-1.0 meters above the ground. The traps and repellents are arranged alternately.

[0024] The beneficial effects of this invention are as follows:

[0025] The present invention provides a trap for fourth-instar nymphs of the bamboo oval bug, along with an attractant and repellent agent and an application method. The trap involves inserting a stake into a bamboo forest and placing a slow-release bottle filled with an attractant on a socket at the top of the stake. This attracts the target nymphs. Combined with sticky traps arranged in a cross shape along the side of the stake, the attracted nymphs are captured. This avoids the environmental pollution caused by chemical control and the excessive manpower required for physical control. Furthermore, placing the slow-release bottle containing the repellent between adjacent devices utilizes the synergy between the attractant and repellent, improving the trapping efficiency.

[0026] An installation plate is rotatably mounted on the top of the sticking rod, and horizontal plates are evenly installed on the sides of the installation plate. At the same time, vertical plates are hinged to the bottom of the horizontal plates, fixing the sticky insect board between the horizontal and vertical plates. Under the action of wind, the sticky insect board can rotate around the sticking rod, making the insects stick more evenly. The rotation of the sticky insect board can also accelerate the release of the attractant, resulting in better use.

[0027] By installing an upper partition net between the tops of multiple horizontal plates and a lower partition net between the bottoms of the vertical plates, and by installing retractable side partition nets inside the vertical plates, the device can effectively prevent fallen leaves from sticking to the insect trap during use, thus ensuring the insect trapping effect.

[0028] By incorporating an installation cavity, a lower L-shaped rod, a positioning insertion hole, a lower spring, a through hole, an upper L-shaped rod, and an upper spring inside the insertion rod, and in conjunction with the insertion block at the end of the crossbar, the device automatically controls the opening of the slow-release bottle and releases the locking state between the bottom of the insertion rod and the cone head when unfolded, ensuring that the sticky insect board can rotate during use. After the device is folded, it automatically closes the slow-release bottle and locks the position of the cone head, facilitating the rotation, removal, and movement of the device. The device is more convenient to unfold and use, and has higher practicality. Attached Figure Description

[0052] To enable those skilled in the art to more clearly understand the technical solution of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0053] like Figures 1-9 As shown, this embodiment provides a trap for fourth-instar nymphs of the bamboo oval bug, including a rod 1, a socket 2 fixed to the top of the rod 1, a slow-release bottle 3 installed on the top of the socket 2, a diffusion sponge 4 evenly distributed around the outer side of the rod 1, a drainage groove 5 opening at the top inner side of the rod 1 to connect the bottom of the slow-release bottle 3 and the diffusion sponge 4, a mounting plate 6 horizontally rotatably installed at the top of the rod 1 below the socket 2, a horizontal bar 7 evenly hinged to the outer side of the mounting plate 6, a vertical bar 10 hinged to the bottom inner side of the horizontal bar 7 away from the rod 1, a sticky insect board 14 suspended between the bottom of the horizontal bar 7 and the inner side of the vertical bar 10, and a leaf protection mechanism surrounding the sticky insect board 14 on the outside of the rod 1.

[0054] General working principle: Before use, the crossbar 7 is attached to the outside of the insert rod 1, and the device is in a retracted state. In use, first, the attractant is stored inside the slow-release bottle 3, and then inserted into the socket 2. At this time, the slow-release bottle 3 is in a sealed state. Then, the device is moved to the designated location, and the bottom end of the insert rod 1 is vertically inserted into the soil. After fixing the position of the insert rod 1, the crossbar 7 is extended outwards to a maximum angle of 90 degrees. When the crossbar 7 is extended, the slow-release bottle 3 is released from its sealed state, and the attractant drips downwards into the diffusion sponge 4. The attractant spreads outwards to lure insects. After the horizontal bar 7 is fully extended, the vertical bar 10 is extended vertically downwards. Then, a sticky insect board 14 is suspended between the bottom of the horizontal bar 7 and the inner side of the vertical bar 10. A leaf protection mechanism is used to prevent fallen leaves from sticking to the sticky insect board 14. The installation of the device is complete. During use, because the mounting plate 6 and the insertion rod 1 are rotatably connected, the sticky insect board 14 can rotate around the insertion rod 1 under the action of wind. This not only accelerates the diffusion of the attractant, but also makes the surface of the sticky insect board 14 more evenly stick to the insects.

[0055] In this embodiment, a rotating rod 703 is rotatably mounted on the end of the crossbar 7. The end of the rotating rod 703 is fixed to the outside of the mounting plate 6. A torsion spring 704 is sleeved on the end of the rotating rod 703. One end of the torsion spring 704 is fixedly connected to the crossbar 7, and the other end of the torsion spring 704 is fixedly connected to the mounting plate 6.

[0056] Local working principle: When the crossbar 7 and the insert rod 1 are in contact and in a contracted state, the bottom end of the crossbar 7 is limited, while the torsion spring 704 is in a compressed state. When the crossbar 7 is pulled up, the crossbar 7 is released from the limited state and will automatically return to its original position under the elastic force of the torsion spring 704, remaining parallel to the horizontal plane.

[0057] In this embodiment, the bottom of each horizontal bar 7 is provided with a storage groove 701, the vertical bar 10 is located inside the storage groove 701, the two ends of the side of the horizontal bar 7 are each provided with a first hook 702, the side of the horizontal bar 7 is provided with a limiting groove, the first hook 702 is stored inside the limiting groove, the two ends of the inner side of the vertical bar 10 are each provided with a second hook 1001, the first hook 702 and the second hook 1001 are respectively hung on both sides of the sticky insect board 14.

[0058] Local working principle: In the retracted state, the vertical rod 10 can be completely hidden inside the horizontal rod 7, reducing the size of the device. During the unfolding process, the vertical rod 10 will remain vertical under the action of gravity and frictional resistance with the inside of the storage groove 701. When installing the sticky insect board 14, holes are opened at the positions of the first hook 702 and the second hook 1001 respectively, so that the first hook 702 and the second hook 1001 can hook the sticky insect board 14.

[0059] In this embodiment, the leaf protection mechanism includes an upper partition net 8, a receiving sleeve 9, a lower partition net 11, a side partition net 12, and a retraction and release assembly 13. The upper partition net 8 is circular and fixed to the top of multiple sets of horizontal bars 7. The receiving sleeve 9 is rotatably installed at the bottom of the insert rod 1. The lower partition net 11 is provided between the side of the receiving sleeve 9 and the bottom end of the vertical rod 10. The side partition net 12 is provided between adjacent vertical rods 10. The retraction and release assembly 13 for controlling the retraction and release of the side partition net 12 is provided inside the vertical rod 10.

[0060] Local working principle: The upper partition net 8 is always fixed to the top of the horizontal bar 7. When it is retracted, the upper partition net 8 wraps around the outside of the horizontal bar 7 to prevent the horizontal bar 7 from unfolding. When the horizontal bar 7 is unfolded, the upper partition net 8 automatically lays flat. The lower partition net 11 at the bottom of the vertical bar 10 is fixed to the side of the receiving sleeve 9 and the bottom of the vertical bar 10. In the retracted state, it wraps around the outside of the insertion rod 1. After the vertical bar 10 is unfolded, the lower partition net 11 lies flat at the bottom. The side partition net 12 is initially stored inside the vertical bar 10. After the sticky insect board 14 is installed, the side partition net 12 is pulled out and fixed to another vertical bar 10, forming protection on the top, bottom and outer periphery of the sticky insect board 14 to prevent fallen leaves from sticking together.

[0061] In this embodiment, the take-up and take-down assembly 13 includes a storage slot 1301, a take-up rod 1302, a spring 1303, a strip-shaped opening 1304, a third hook 1201, and a hanging ring 1002. The storage slot 1301 is opened inside the vertical rod 10 along its length. The take-up rod 1302 is rotatably mounted between the two ends of the storage slot 1301. Springs 1303 are respectively installed at both ends of the take-up rod 1302. The inner end of the spring 1303 is fixedly connected to the take-up rod 1302, and the outer end of the spring 1303 is fixedly connected to the inner end of the storage slot 1301. The side partition 12 is wound and installed on the take-up rod 1302. A strip-shaped opening 1304 is opened on the side of the vertical rod 10 for the side partition 12 to pass through. The outer end of the side partition 12 is equipped with a third hook 1201. A hanging ring 1002 that cooperates with the third hook 1201 is provided on the outer side of the vertical rod 10.

[0062] Local working principle: In the initial state, the side partition 12 is wound around the winding rod 1302, with only the third hook 1201 at the end of the side partition 12 located on the outside of the vertical rod 10. When the side partition 12 needs to be pulled out for use, the rotation of the winding rod 1302 is controlled to compress the spring 1303, ensuring that the side partition 12 remains taut after being fixed. After being unlocked, it can automatically be wound into the interior of the vertical rod 10 under the elastic force of the spring 1303.

[0063] In this embodiment, a scraper 901 that fits against the outside of the diffusion sponge 4 is vertically fixed to the bottom of the mounting plate 6, and a conical cover 902 is fixed to the outside of the insertion rod 1 and inside the receiving sleeve 9.

[0064] Local working principle: When the mounting plate 6 rotates around the insertion rod 1, if an insect is on the surface of the diffusion sponge 4, the scraper 901 can scrape the insect off, and the insect will fall into the inside of the receiving sleeve 9. The conical cover 902 is used to prevent the insect from flying out again.

[0065] In this embodiment, the top of the socket 2 is provided with a receiving groove 201, the bottom end of the slow-release bottle 3 is inserted into the inside of the receiving groove 201, the bottom end of the slow-release bottle 3 is provided with evenly distributed leakage holes 301, the bottom of the insert rod 1 is provided with an installation cavity 103, the side of the installation cavity 103 is provided with evenly distributed through holes 107, and insert blocks 108 are slidably installed inside the through holes 107. The insert blocks 108 are respectively fixed to the bottom end of the inner side of the crossbar 7. The top of the insert rod 1 is evenly vertically slidably installed with an upper L-shaped rod 109. The bottom end of the upper L-shaped rod 109 extends into the inside of the installation cavity 103. An upper spring 1010 is provided between the bottom end of the upper L-shaped rod 109 and the top of the installation cavity 103. The top end of the upper L-shaped rod 109 extends into the inside of the receiving groove 201, and the top end of the upper L-shaped rod 109 is respectively attached to the bottom of the leakage holes 301.

[0066] Local working principle: When the slow-release bottle 3 is installed, the device is in a retracted state. The insert 108 on the crossbar 7 is inserted into the installation cavity 103 and squeezes the bottom end of the upper L-shaped rod 109. The upper spring 1010 is in a compressed state, aligning the bottom end of the slow-release bottle 3 with the receiving groove 201 and inserting it. The bottom end of the leakage hole 301 is aligned with the upper L-shaped rod 109. After the slow-release bottle 3 is installed, the leakage hole 301 is blocked by the top end of the upper L-shaped rod 109. When the crossbar 7 is unfolded for use, the insert 108 is pulled out from the installation cavity 103, releasing the squeezing state of the upper L-shaped rod 109. The upper spring 1010 controls the upper L-shaped rod 109 to reset. The upper L-shaped rod 109 moves down, and the slow-release bottle 3 slowly releases the attractant.

[0067] In this embodiment, a cone head 101 is rotatably mounted on the bottom end of the insertion rod 1. A spiral blade 102 is provided on the outer side of the cone head 101. A lower L-shaped rod 104 is uniformly and vertically slidably mounted inside the insertion rod 1. The top end of the lower L-shaped rod 104 is located inside the mounting cavity 103. The bottom end of the lower L-shaped rod 104 extends to the bottom of the insertion rod 1. A lower spring 106 is provided between the top end of the lower L-shaped rod 104 and the bottom of the mounting cavity 103. A positioning insertion hole 105 that mates with the lower L-shaped rod 104 is opened on the top of the cone head 101.

[0068] Partial working principle: When the device is fixedly installed, it is in a retracted state. The insert block 108 not only compresses the upper L-shaped rod 109, but also the lower L-shaped rod 104. The lower L-shaped rod 104 is controlled to move downward and insert into the positioning hole 105, and compresses the lower spring 106. The cone head 101 is locked by the lower L-shaped rod 104. Therefore, the cone head 101 and the insert rod 1 are integrated. The cone head 101 can be quickly inserted into the soil by rotating the insert rod 1. After the fixation is completed, the crossbar 7 unfolds, and the insert block 108 is pulled out from the installation cavity 103, releasing the compression on the lower L-shaped rod 104. The lower L-shaped rod 104 is reset under the elastic force of the lower spring 106, releasing the fixed state of the cone head 101. At this time, the insert rod 1 is in a movable state and can rotate freely. Under the action of wind, the sticky insect board 14 can rotate.

[0069] like Figures 1-9 As shown in the figure, this embodiment provides the following formulation components and proportions of an attractant and repellent for the fourth instar nymphs of the bamboo oviduct bug:

[0070] The attractant formulation includes nonanal, hexanal, phenylacetaldehyde, and hexane in a weight ratio of (1-2):(1-2):(20-30):(1000 minus the sum of the weights of nonanal, hexanal, and phenylacetaldehyde).

[0071] The repellent formulation includes caryophyllene, camphor, β-pinene, and hexane in a weight ratio of (25-100): (1-100): (25-100): (1000 minus the sum of the proportions of caryophyllene, camphor, and L-β-pinene).

[0072] Experiment 1: Insect Behavior Experiment to Determine the Behavioral Response of Fourth Instar Bamboo Bug Nymphs to Nononal, Hexanal, Phenylacetaldehyde, Caryophyllene, Camphor, and β-pinene. Hexane, in which the fourth instar Bamboo bug nymphs showed no significant behavioral response, served as the control group.

[0091] The results of Experiment 2 show that the reagent combinations selected from the reagent ratios protected by this patent all exhibit significant or extremely significant experimental effects.

[0092] like Figures 1-9 As shown in the figure, this embodiment provides a trap for fourth-instar nymphs of the bamboo oval bug and a method for applying the attractant and repellent as follows:

[0093] Step 1: First, fill the inside of the slow-release bottle 3 with the attractant, then insert the bottom of the slow-release bottle 3 into the receiving slot 201 on the socket 2. The leakage hole 301 at the bottom of the slow-release bottle 3 is blocked by the upper L-shaped rod 109, and the bottom of the slow-release bottle 3 is in a sealed state.

[0094] Step 2: Move the insertion rod 1 to the designated position, and then insert the insertion rod 1 vertically into the ground, with the cone head 101 fully inserted into the ground;

[0095] Step 3: Pull the insert 108 at the bottom of the crossbar 7 out of the mounting cavity 103 to release the seal on the slow-release bottle 3 and the locking state of the cone 101. The lower L-shaped rod 104 and the upper L-shaped rod 109 are reset by the elastic force of the lower spring 106 and the upper spring 1010. The attractant inside the slow-release bottle 3 is released and drips into the diffusion sponge 4 and evaporates outward. The reset of the lower L-shaped rod 104 releases the locking state between the insert 1 and the cone 101, and the insert 1 can rotate on the ground.

[0096] Step 4: Horizontal bar 7 is unfolded horizontally, and the top of horizontal bar 7 is covered by upper partition net 8. Then, vertical bar 10 is flipped downwards to be vertical, and the bottom of vertical bar 10 is covered by lower partition net 11. Then, sticky insect board 14 is suspended between the inside of horizontal bar 7 and the inside of vertical bar 10. Finally, side partition net 12 is pulled out from the inside of vertical bar 10, and the third hook 1201 at the end of vertical bar 10 is hung on hanging ring 1002. Upper partition net 8, lower partition net 11 and side partition net 12 provide external protection for sticky insect board 14.

[0097] Step 5: After the insertion of the stakes 1 at intervals is completed, fix the slow-release bottle 3 containing the repellent directly onto the bamboo poles in the forest, 0.5-1.0 meters above the ground. Arrange the traps and repellents alternately, as shown below. Figure 9 In the diagram, the square in the middle represents the attractant, the circle represents the repellent, the small arrow indicates the direction of attraction by the attractant, and the large arrow indicates the direction of repellency by the repellent. In other words, the arrows represent the movement direction of the fourth instar nymphs of the bamboo oval bug. The attractant and repellent are arranged alternately, and there are double arrows pointing towards the attractant between the attractant and the repellent, which increases the trapping effect.

[0098] The above description is merely a further embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
