Description
Technical Field
[0001] This utility model relates to the field of pest control technology, specifically to a device for preventing adult peach-necked longhorn beetles from mating and laying eggs. Background Technology
[0002] The peach red-necked longhorn beetle is a serious pest that severely damages various fruit trees, especially stone fruits such as peaches, apricots, and plums. During mating and egg-laying, the adults choose suitable locations on the trunk, such as bark cracks or wounds, to lay their eggs. After hatching, the larvae bore into the trunk, feeding in the xylem and creating irregular tunnels. This damages the tree's vascular tissue, affecting the transport of water and nutrients, leading to weakened tree growth, and in severe cases, even causing the entire tree to die.
[0003] Currently, the main control methods for the peach red-necked longhorn beetle include chemical control, physical control, and biological control. Chemical control commonly employs two methods: spraying pesticides and trunk injection. While spraying pesticides onto the trunk surface has some effect on newly hatched larvae boring into the trunk, the adult beetle's active period is long, lasting 30-50 days. Frequent application of pesticides can easily cause environmental pollution and harm natural enemies, thus disrupting the ecological balance. Furthermore, for adults with strong flight capabilities, pesticide spraying alone is not ideal. Trunk injection can easily cause phytotoxicity to the tree and lead to pesticide residue exceeding safe limits in nearly mature fruit, affecting fruit safety. Among physical control methods, manual capture of adults and digging out larvae are somewhat effective, but they are inefficient and difficult to apply widely in large orchards or woodlands, and can easily cause secondary damage to the tree. Biological control mainly utilizes natural enemy insects or pathogenic microorganisms to control the population of the peach-necked longhorn beetle. However, the effectiveness of biological control is greatly affected by environmental factors, the control effect is unstable, and the cost is relatively high, making it difficult to meet the control needs in actual production. Utility Model Content
[0004] The purpose of this invention is to provide a device for preventing adult peach red-necked longhorn beetles from mating and laying eggs. This device uses a barrier net to cover the tree trunk, so that there is no mating space for adults inside the barrier net and the outside can block the laying of eggs by adults from outside, thus curbing the damage of peach red-necked longhorn beetles to fruit trees.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A device for preventing adult peach-necked longhorn beetles from mating and laying eggs includes a barrier net, which is fitted onto a tree trunk. A first snap-fit part is provided on one side of the barrier net, and a second snap-fit part is provided on the other side of the barrier net. The first snap-fit part and the second snap-fit part are snapped together to form a mesh bag that fits tightly against the tree trunk. The top and bottom of the barrier net are fixed to the tree trunk by binding strips.
[0006] Preferably, the first snap-fit part is a first hook-and-loop fastener surface disposed on one side of the front of the barrier net, and the second snap-fit part is a first hook-and-loop fastener surface disposed on the other side of the back of the barrier net, and the snap-fit is achieved by the first hook-and-loop fastener surface and the first hook-and-loop fastener surface being adhered to each other.
[0007] Preferably, the first hook and loop fastener is arranged along the length of the barrier mesh and has the same length as the barrier mesh; the first loop and loop fastener is arranged along the width of the barrier mesh, and the first loop and loop fastener is evenly provided with multiple strips.
[0008] Preferably, a second hook-and-loop fastener is provided at the top front of the barrier net, and a second hook-and-loop fastener is provided at the bottom back of the barrier net, for longitudinal splicing of multiple barrier nets.
[0009] Preferably, the binding strips are made of a flexible material and are used to wrap around the tree trunk to secure the barrier net. The binding strips are positioned at the top and bottom edges of the barrier net.
[0010] Preferably, the length of the barrier net is in the range of 20-40 cm.
[0011] Preferably, the width of the barrier net is in the range of 30-90 cm.
[0012] Preferably, the barrier net is white; and chemical pesticides are sprayed on the barrier net.
[0013] In the above technical solution, by setting up a barrier net, the fruit trees are protected from the infestation of adult peach red-necked longhorn beetles, while the barrier net is also breathable and will not affect the normal growth of the fruit trees. By attaching a first hook-and-loop fastener to one side of the barrier net and a second hook-and-loop fastener to the other side of the reverse side, the barrier net can be tightly adhered to the tree trunk to form a mesh bag. During use, the hook-and-loop fasteners deform under tension and compression, ensuring a tight fit between the mesh bag and the fruit tree. This eliminates the space required for adult peach red-necked longhorn beetles to mate, thus blocking their mating behavior at the source. Meanwhile, when laying eggs, the adult peach-necked longhorn beetle needs to find relatively loose, easily accessible locations such as bark crevices or wounds that can accommodate its eggs. The barrier net designed in this application, with its fine mesh, forms an absolute physical barrier, preventing the adult beetle from penetrating the mesh to reach the inside of the trunk. This prevents adult peach-necked longhorn beetles outside the barrier net from laying their eggs on the trunk or large branches of the fruit tree. Furthermore, the first hook side of the hook and loop fastener is set along the length of the barrier net, and the loop side of the first hook and loop fastener is perpendicular to the hook side and evenly distributed in multiple strips. The barrier net wraps around the outside of the trunk through the intersection of the hook and loop sides of the first hook and loop fastener. Because the loop side of the first hook and loop fastener is relatively long, it can wrap trunks of different thicknesses.
[0014] Furthermore, the top and bottom of the barrier net are secured to the tree trunk with binding strips, ensuring the net remains firmly in place. A second hook-and-loop fastener is provided on the top front of the net, and a second hook-and-loop fastener on the bottom back, allowing for longitudinal splicing of multiple nets. This protects tree trunks of varying lengths. The longitudinal splicing also reduces the overall size of the net, making it easier to install. Attached Figure Description

Detailed Implementation
[0016] The present invention will be further described below with reference to the accompanying drawings: like Figures 1 to 3As shown, this device for preventing adult peach red-necked longhorn beetles from mating and laying eggs includes a barrier net 1. The barrier net 1 can be woven from white polyethylene or polypropylene fibers. The white barrier net 1 has a visual disturbance effect on adult peach red-necked longhorn beetles, which can reduce their willingness to approach fruit trees to a certain extent. At the same time, the fiber material gives the barrier net 1 a certain strength and flexibility, making it less likely to be damaged when wrapped around the trunk or large branches of the fruit tree. The mesh density of this barrier net 1 is not less than 20 meshes, which can prevent adult peach red-necked longhorn beetles from passing through while also allowing ventilation and breathability, so as not to affect the normal growth of fruit trees.
[0017] A first snap-fit part is provided on one side of the barrier net 1, and a second snap-fit part is provided on the other side of the barrier net 1. By snapping the first snap-fit part and the second snap-fit part together, the barrier net 1 forms a mesh bag. The mesh bag fits tightly against the tree trunk, wrapping the tree trunk in all directions, so that there is no space for the peach red-necked longhorn beetle adult to move between the mesh bag and the tree trunk, thereby preventing the peach red-necked longhorn beetle adult to mate and lay eggs inside the mesh bag.
[0018] The first snap-fit part is a first hook-and-loop fastener 2 located on one side of the front of the barrier net 1, and the second snap-fit part is a first hook-and-loop fastener 3 located on the other side of the back of the barrier net 1. The first hook-and-loop fastener 2 is set along the length of the barrier net 1 and its length is consistent with the barrier net 1, so that there is sufficient adhesive area in the length direction. Multiple first hook-and-loop fasteners 3 are evenly arranged along the width direction of the barrier net 1, which increases the flexibility and stability of the snap-fit. During the installation operation, the barrier net 1 is wrapped around the tree trunk, so that the first hook-and-loop fastener 2 and the first hook-and-loop fastener 3 intersect each other, and are glued at the intersection point, thus forming a mesh bag that fits tightly against the tree trunk. By gluing the first hook-and-loop fastener 2 to the first hook-and-loop fastener 3 at different positions, the needs of tree trunks of different thicknesses can be met. In this way, the mesh bag achieves all-round wrapping of the tree trunk, so that there is no space for the adult peach red-necked longhorn beetle to move between the mesh bag and the tree trunk, thereby preventing the adult peach red-necked longhorn beetle that has emerged from the tree trunk from mating and laying eggs inside the mesh bag. The Velcro will deform during the pasting process, preventing it from forming a high support point on the tree trunk. At the same time, it will fit tightly with the direction of the tree trunk's curvature, eliminating the possibility of providing activity space for adult peach-necked longhorn beetles.
[0019] Taking peach trees as an example, in actual fruit tree cultivation, peach trees are generally pruned and shaped in an open-center form. The length of the main trunk is generally about 30-60 cm, and the diameter is generally about 10-30 cm. The length of this barrier net 1 is set to 20-40 cm, and the width is 30-90 cm. The specific dimensions of the length and width of this barrier net can be set according to the age and growth of peach trees. A second Velcro hook side 4 is set on the top of the front side of the barrier net 1, and a second Velcro loop side 5 is set on the bottom of the back side for longitudinal splicing of multiple barrier nets 1. When the barrier net 1 is wrapped around the trunk, the upper and lower ends of the barrier net 1 are tied tightly with binding strips to fix the barrier net 1 to the trunk and prevent it from shifting.
[0020] After the barrier net 1 is constructed, a contact pesticide is evenly sprayed onto its surface. Microencapsulated suspensions can be used; these pesticides utilize microencapsulation technology to encapsulate the active ingredient within a UV-resistant film, offering both rapid and sustained action, and enhancing resistance to rain washout. This ensures that adult beetles both inside and outside the barrier net 1 are killed upon contact. Alternatively, repellent agents can be added to induce avoidance behavior in adult peach-necked longhorn beetles approaching the barrier net 1, creating a dual protective mechanism with the visual interference of the white netting, thus improving control efficacy.
[0021] In the above technical solution, the first hook and loop fastener 2, the first hook and loop fastener 3, the second hook and loop fastener 4, and the second hook and loop fastener 5 are attached to the barrier net 1 by adhesive or sewing with thread. In this application, the thread sewing method is used, which makes it less likely for the first hook and loop fastener 2, the first hook and loop fastener 3, the second hook and loop fastener 4, and the second hook and loop fastener 5 to fall off the barrier net 1 when exposed to the environment for a long time.
[0022] When using this device, first select an appropriate number of barrier nets 1 according to the height of the tree trunk. In this application, we will use a tree trunk height of 30 cm and a diameter of 10 cm as an example, with a length of 20 cm and a width of 40 cm for the barrier net 1. According to the height of the tree trunk, select two barrier nets 1 to splice together. First, according to the height of the tree trunk, the side of the top barrier net 1 with the first hook and loop fastener 3 should face away from the tree trunk. Then, wrap the barrier net 1 around the tree trunk and tighten it so that the barrier net 1 is tightly attached to the tree trunk. At this time, attach the first hook and loop fastener 2 to the first hook and loop fastener 3 to form a mesh bag. Simultaneously, secure the top of the barrier net 1 with the binding strip. Then, attach the second hook and loop side 5 of the bottom barrier net 1 to the outside of the second hook and loop side 4 and repeat the installation steps of the top barrier net 1. Since the bottom barrier net 1 is relatively long, the part exceeding the length of the tree trunk needs to be folded upwards and attached using the first hook and loop side 2 and the first hook and loop side 3. At this point, the wrapping of the tree trunk is complete. Finally, secure the bottom of the bottom barrier net 1 with the binding strip. Alternatively, first connect the second hook and loop side 4 and the second hook and loop side 5. After the connection is complete, simply wrap the entire connected part around the outside of the tree trunk. Finally, secure the top and bottom of the connected part with the binding strip.
[0023] Since the adult red-necked longhorn beetle takes about 1-2 months to emerge and mate, the device can be installed on the peach tree trunk with fresh insect excrement one week before the adults emerge. The device can be removed and retrieved after 2 months to prevent it from aging and decomposing due to long-term exposure. The retrieved device can be used again the following year, which can save production costs and does not affect the thickening and growth of the tree trunk.
[0024] This embodiment is merely an illustration of the concept and implementation of this utility model, and is not intended to limit it. Under the concept of this utility model, the technical solution without substantial changes is still within the protection scope.
