Description

Technical Field

[0001] The present invention relates to a trap, in particular to a trap for fourth-instar nymphs of bamboo ovale bugs. The present invention also relates to an attractant and repellent, in particular to an attractant and repellent for fourth-instar nymphs of bamboo ovale bugs. The present invention also relates to an application method, in particular to a trap for fourth-instar nymphs of bamboo ovale bugs and an application method of the attractant and repellent, belonging to the technical field of forest protection. Background Art

[0002] Hippotiscus dorsalis belongs to the family Pentatomidae of the order Hemiptera. It mainly harms economic bamboo species such as moso bamboo, bamboo of the family Phyllostachys pubescens, and bamboo of the family Psoralea corylifolia. The bamboo stink bug overwinters as 3rd-4th instar nymphs, and the 4th instar nymphs first feed on bamboo in March-April of the following year. Exploring the control technology for the 4th instar nymphs can reduce the damage of bamboo stink bug to bamboo from the source. The current control methods for the 4th instar nymphs are mainly as follows: in April-May, when the nymphs of bamboo stink bugs are at their peak of damage, groove insect traps are used to catch the nymphs; before the 4th instar nymphs land on the bamboo, a closed oil ring is applied to the base of the bamboo stalk using a mixture of butter and motor oil to prevent the nymphs from landing on the bamboo; chemical control uses various chemical agents through spraying, dusting, or ring poisoning to achieve the purpose of reducing the insect population density.

[0003] The above methods also have many disadvantages in the control of bamboo egg stink bugs. The use of insect traps for collection consumes a lot of manpower and is labor-intensive. The use of insect sticky agents requires operation on all bamboos in the bamboo forest, which is labor-intensive, and butter, motor oil, etc. can easily cause environmental pollution. Chemical reagents for control can easily cause environmental pollution.

[0004] Therefore, a trap for the fourth-instar nymphs of the bamboo stink bug, an attractant and a repellent, and an application method were designed to optimize the above-mentioned problems. Summary of the Invention

[0005] The main purpose of the present invention is to provide a trap for fourth-instar nymphs of bamboo egg stink bugs, an attractant and repellent, and an application method. The method comprises the following steps: a rod is fixedly inserted into a bamboo forest, and a slow-release bottle is arranged on the socket at the top of the rod, and the interior of the slow-release bottle is filled with an attractant to attract the target nymphs. The sticky insect boards arranged in a cross shape on the side of the rod can capture the lured nymphs, thereby avoiding the pollution of the environment by chemical control and the excessive consumption of manpower by physical control. In addition, the slow-release bottle containing the repellent is placed between adjacent devices, and the attractant and repellent cooperate with each other to improve the trapping efficiency. A mounting disk is rotatably installed on the top of the rod, and horizontal plates are evenly installed on the sides of the mounting disk. At the same time, a vertical plate is hingedly installed on the bottom of the horizontal plate. The sticky insect board is fixed between the horizontal plate and the vertical plate. Under the action of wind, the sticky insect board can rotate around the rod, so that the insects stick more evenly, and the rotation of the sticky insect board is smooth. The rotation can also speed up the distribution of the attractant, and the effect of use is better. An upper partition net is provided between the tops of multiple groups of horizontal plates, and a lower partition net is provided between the bottom ends of the vertical plates. At the same time, a retractable side partition net is provided inside the vertical plates. During the use of the device, fallen leaves can be effectively prevented from sticking to the insect-catching board, ensuring the effect of trapping insects. An installation cavity, a lower L-shaped rod, a positioning socket, a lower spring, a through hole, an upper L-shaped rod, and an upper spring are provided inside the insertion rod, and then used in conjunction with the insertion block at the end of the horizontal rod, so that when the device is unfolded and used, it can automatically control the opening of the slow-release bottle and release the locking state of the bottom end of the insertion rod and the cone head to ensure that the insect-catching board can be rotated during use.

[0023] Step 5: After the poles are spaced apart, fix the slow-release bottle containing the repellent directly on the bamboo pole in the forest, 0.5-1.0 meters above the ground, and arrange the traps and repellent combinations at intervals.

[0024] The beneficial effects of the present invention are:

[0025] The present invention provides a trap for fourth-instar nymphs of bamboo ovale bugs, an attractant and repellent, and an application method. A rod is fixedly inserted into a bamboo forest, and a slow-release bottle is arranged on the socket on the top of the rod. The slow-release bottle is filled with an attractant to attract target nymphs. The attractant is then captured in conjunction with sticky insect plates distributed in a cross shape on the side of the rod, thereby avoiding environmental pollution caused by chemical control and excessive consumption of manpower by physical control. In addition, the slow-release bottle containing the repellent is placed between adjacent devices, and the attractant and repellent cooperate with each other to improve the trapping efficiency.

[0026] A mounting plate is rotatably installed on the top of the insertion rod, and horizontal plates are evenly installed on the sides of the mounting plate. At the same time, a vertical plate is hingedly installed on the bottom of the horizontal plate to fix the insect sticking board between the horizontal plate and the vertical plate. Under the action of wind, the insect sticking board can rotate around the insertion rod, so that the insects are stuck more evenly, and the rotation of the insect sticking board can also speed up the distribution of the attractant, and the use effect is better.

[0027] By arranging upper partition nets between the tops of multiple groups of horizontal boards and lower partition nets between the bottom ends of vertical boards, and at the same time providing retractable side partition nets inside the vertical boards, during the use of the device, fallen leaves can be effectively prevented from sticking to the insect sticky boards, thereby ensuring the insect trapping effect.

[0028] By arranging an installation cavity, a lower L-shaped rod, a positioning socket, a lower spring, a through hole, an upper L-shaped rod, and an upper spring inside the insertion rod, and then using it in conjunction with the plug block at the end of the cross rod, the device can automatically control the opening of the slow-release bottle when it is unfolded and used, and release the locking state of the bottom end of the insertion rod and the cone head to ensure that the insect sticking board can be rotated during use. After the device is folded, the slow-release bottle can be automatically closed and the cone head can be locked in position to facilitate the rotation, extraction and movement of the device. The folding and use of the device are more convenient and more practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and 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 the fourth-instar nymphs of bamboo egg stink bugs, including an insertion rod 1, a socket 2 is fixed on the top of the insertion rod 1, a slow-release bottle 3 is installed on the top of the socket 2, a diffusion sponge 4 is evenly provided on the outer side of the insertion rod 1 along the circumferential direction, and a drainage groove 5 is opened on the inner top of the insertion rod 1 to connect the bottom end of the slow-release bottle 3 and the diffusion sponge 4. The top of the insertion rod 1 is located below the socket 2 and is horizontally rotatably installed with a mounting plate 6, and the outer side of the mounting plate 6 is evenly hingedly installed with a cross bar 7, and the inner bottom end of the cross bar 7 away from the insertion rod 1 is hingedly installed with a vertical bar 10, and a sticky board 14 is suspended between the bottom of the cross bar 7 and the inner side of the vertical bar 10, and a fallen leaf protection mechanism is provided on the outside of the insertion rod 1 around the outside of the sticky board 14.

[0054] The overall working principle: before use, the cross bar 7 is attached to the outside of the insertion rod 1, and the device is in a closed state. When in use, first store the attractant in the slow-release bottle 3, and then insert it into the socket 2. At this time, the slow-release bottle 3 is in a blocked state, and then the device is moved to the designated point, and the bottom end of the insertion rod 1 is vertically inserted into the soil. After the position of the insertion rod 1 is fixed, the cross bar 7 is unfolded outward, and the maximum unfolding angle of the cross bar 7 is 90 degrees. When the cross bar 7 is unfolded, the slow-release bottle 3 is unblocked, and the attractant will drip downward and flow into the diffusion sponge 4 The device is installed so that the insects can be attracted by the insect sticking board 14. The insect sticking board 14 is installed between the bottom of the horizontal bar 7 and the inner side of the vertical bar 10, and the fallen leaves protection mechanism is used to prevent the fallen leaves from adhering to the insect sticking board 14. The installation of the device is completed. During use, due to the rotation connection between the mounting plate 6 and the insertion rod 1, the insect sticking board 14 can rotate around the insertion rod 1 under the action of wind, which can not only accelerate the diffusion of the attractant, but also make the insects more evenly adhered to the surface of the insect sticking board 14.

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

[0056] Local working principle: When the cross bar 7 is in contact with the surface of the insertion rod 1 and is in a contracted state, the bottom end of the cross bar 7 is limited, and the torsion spring 704 is in a compressed state. When the cross bar 7 is pulled up, the cross bar 7 is released from the limited state and will automatically reset under the elastic force of the torsion spring 704, keeping it parallel to the horizontal plane.

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

[0058] Partial working principle: In the retracted state, the vertical rod 10 can be completely hidden inside the horizontal rod 7, reducing the volume of the device. During the unfolded use process, the vertical rod 10 will remain vertical under the action of gravity and the friction resistance with the inner side of the storage slot 701. When installing the sticky insect board 14, holes are respectively opened at the positions of the sticky insect board 14 corresponding to the first hook 702 and the second hook 1001, so that the first hook 702 and the second hook 1001 can hook the sticky insect board 14.

[0059] In this embodiment, the fallen 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 retractable assembly 13. The upper partition net 8 is circular and fixed on the top of multiple groups of cross bars 7. The receiving sleeve 9 is rotatably installed at the bottom of the insertion rod 1. A lower partition net 11 is provided between the side of the receiving sleeve 9 and the bottom end of the vertical rod 10. Side partition nets 12 are provided between adjacent vertical rods 10. A retractable assembly 13 for controlling the contraction and release of the side partition nets 12 is provided inside the vertical rod 10.

[0060] Local working principle: the upper partition net 8 is always fixed on the top of the cross bar 7. When it is retracted, the upper partition net 8 is wrapped around the outside of the cross bar 7 to prevent the cross bar 7 from unfolding. When the cross bar 7 is unfolded, the upper partition net 8 is automatically flattened, and 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 is wrapped around the outside of the insertion rod 1. After the vertical bar 10 is unfolded, the lower partition net 11 is flattened at the bottom. The side partition net 12 is initially stored inside the vertical bar 10. After the insect sticking 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 peripheral surface of the insect sticking board 14 to prevent fallen leaves from sticking.

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

[0062] Local working principle: In the initial state, the side partition net 12 is wrapped around the winding rod 1302, and only the third hook 1201 at the end of the side partition net 12 is located on the outside of the vertical rod 10. When the side partition net 12 needs to be pulled out for use, the rotation of the winding rod 1302 will be controlled, and the clockwork spring 1303 will be compressed to ensure that the side partition net 12 remains in a tensioned state after being fixed, and after being unlocked, it can be automatically wound into the inside of the vertical rod 10 under the action of the elastic force of the clockwork spring 1303.

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

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

[0065] In this embodiment, a receiving groove 201 is provided at the top of the socket 2, and the bottom end of the slow-release bottle 3 is inserted into the inside of the receiving groove 201. A leakage hole 301 is evenly provided at the bottom end of the slow-release bottle 3, and a mounting cavity 103 is provided at the inner bottom of the insertion rod 1. A through hole 107 is evenly provided on the side of the mounting cavity 103. Insert blocks 108 are slidably installed inside the through holes 107, and the insert blocks 108 are respectively fixed at the bottom end of the inner side of the cross bar 7. An upper L-shaped rod 109 is evenly and vertically slidably installed on the inner top of the insertion rod 1. The bottom end of the upper L-shaped rod 109 extends to the inside of the mounting cavity 103. An upper spring 1010 is provided between the bottom end of the upper L-shaped rod 109 and the inner top of the mounting cavity 103. The top end of the upper L-shaped rod 109 extends to the inside of the receiving groove 201, and the top end of the upper L-shaped rod 109 is respectively fitted under the leakage hole 301.

[0066] Local working principle: When the slow-release bottle 3 is installed, the device is in a retracted state, the plug 108 on the cross bar 7 is inserted into the interior of the installation cavity 103, and squeezes the bottom end of the upper L-shaped rod 109, and the upper spring 1010 is in a compressed state, the bottom end of the slow-release bottle 3 is aligned with the receiving groove 201 and inserted, and 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 cross bar 7 is unfolded for use, the plug 108 is pulled out from the interior of the installation cavity 103, releasing the squeezing state of the upper L-shaped rod 109, and the upper spring 1010 controls the upper L-shaped rod 109 to reset, and the upper L-shaped rod 109 moves downward, and the slow-release bottle 3 slowly releases the attractant.

[0067] In this embodiment, a cone head 101 is rotatably installed at the bottom end of the insertion rod 1, and a spiral blade 102 is provided on the outside of the cone head 101. A lower L-shaped rod 104 is evenly and vertically slidably installed inside the insertion rod 1. The top of the lower L-shaped rod 104 is located inside the installation cavity 103, and 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 of the lower L-shaped rod 104 and the inner bottom of the installation cavity 103. A positioning socket 105 that cooperates with the lower L-shaped rod 104 is opened on the top of the cone head 101.

[0068] The lower L-shaped rod 104 is reset under the elastic force of the lower spring 106, and the fixed state of the cone head 101 is released. At this time, the rod 1 is in an active state and can rotate freely, ensuring that the insect sticking plate 14 can rotate when the device is subjected to wind force.

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

[0093] Step 1: First, fill the attractant into the interior of the slow-release bottle 3, then insert the bottom end of the slow-release bottle 3 into the receiving slot 201 on the socket 2. The leakage hole 301 at the bottom end 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 rod 1 to the designated position, and then vertically insert the rod 1 into the ground, with the cone head 101 fully inserted into the ground;

[0095] Step 3: Pull out the plug 108 at the bottom end of the crossbar 7 from the interior of the mounting cavity 103, thereby releasing the blockage of the slow-release bottle 3 and the locking state of the cone head 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, drips into the interior of the diffusion sponge 4, and evaporates outward. The reset of the lower L-shaped rod 104 releases the locking state between the insertion rod 1 and the cone head 101, and the insertion rod 1 can rotate on the ground.

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

[0097] Step 5: After the rods 1 are connected at intervals, the slow-release bottle 3 containing the repellent is fixed directly on the bamboo pole in the forest, 0.5-1.0 meters above the ground. The traps and repellents are arranged at intervals, refer to the following Figure 9 In the figure, the middle square represents the attractant, the circle represents the repellent, the small arrow represents the attracting direction of the attractant, and the large arrow represents the repellent direction of the repellent. That is, the arrow represents the movement direction of the fourth-instar nymph of the bamboo egg stink bug. The attractant and the repellent are arranged at intervals, and there is a double arrow pointing towards the attractant between the attractant and the repellent, which increases the trapping effect.
