Description

Technical Field

[0001] This utility model belongs to the field of pine caterpillar larvae capture technology, specifically relating to a larch caterpillar larvae capture device. Background Technology

[0002] Pine caterpillars refer to the juvenile stage of the pine caterpillar, also known as the larval stage. This pest mainly causes serious damage to coniferous trees such as pine and cypress. Pine caterpillars generally have a large appetite and can consume a large number of leaves in a short period of time, causing damage to tree growth and even leading to tree death.

[0003] Common methods for controlling pine caterpillars are mainly divided into physical control, chemical control, and biological control. Chemical control usually involves spraying insecticides directly onto the trees. Some insecticides containing neurotoxins can paralyze or cause pine caterpillar larvae to lose their balance and fall to the ground. However, the toxicity of the insecticides is not enough to kill all pine caterpillar larvae in a short time. Some pine caterpillars can survive for a period of time after falling, and may even climb back onto the tree or find other places to live. In order to better control pests, it is necessary to use a comprehensive capture device to capture and kill the larvae. Utility Model Content

[0004] The purpose of this invention is to provide a larch caterpillar larvae trapping device that can trap and bind larvae that have fallen from the tree, thereby directly reducing the survival rate of fallen larvae, effectively preventing larvae from attempting to climb back onto the tree after falling, preventing them from re-infecting the tree, and reducing the larvae's chances of reproduction.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A larch caterpillar larva trapping device includes a trunk sleeve with an adhesive trapping assembly on the top. The adhesive trapping assembly includes: an insect trapping net installed on the top of the trunk sleeve; a kit fixedly connected to the side surfaces of the trunk sleeve and the insect trapping net; a support rod installed inside the kit; and a double-sided adhesive layer adhered to the inside of the insect trapping net.

[0007] Preferably, a retaining ring is fixedly connected to the outer surface of the trunk sleeve, and a fastening bolt is threaded inside the retaining ring.

[0008] Preferably, the inner side of the trunk sleeve is provided with anti-slip grooves, the anti-slip grooves are horizontally opened, there are several anti-slip grooves, and they are evenly distributed on the inner side of the trunk sleeve, the trunk sleeve is made of elastic material.

[0009] Preferably, the surface of the double-sided adhesive layer is provided with food trapping material, and the food trapping material is evenly spread on the surface of the double-sided adhesive layer.

[0010] Preferably, there are several supporting bent rods, which are evenly distributed on the side surfaces of the trunk sleeve and the insect trap.

[0011] Preferably, the insect trap is attached in a ring shape using Velcro.

[0012] The technical effects achieved by this utility model are as follows:

[0013] In this invention, when it is necessary to capture larvae, the trunk loop can be first wrapped around the surface of the trunk, and the trap can be opened and supported by the supporting curved rod. When the larvae fall from the tree, they will automatically fall into the inside of the open trap, and the double-sided adhesive layer will stick and capture the larvae on its surface. This can effectively prevent larvae that attempt to climb back up the tree after falling, prevent them from re-infecting the tree, and reduce the larvae's reproduction opportunities. This helps to cut off a key link in the pest's life cycle and reduce the spread of pests.

[0014] In this invention, the trunk sleeve and the adhesive trapping assembly can be fixedly installed on the trunk surface by using a retaining ring and a fastening bolt. At the same time, the fastening bolt can be adjusted according to the diameter of the trunk to install the trunk sleeve and the adhesive trapping assembly on trees of different diameters, which not only improves its flexibility but also expands the application range of the adhesive trapping assembly.

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figures 1-3As shown, a larch caterpillar larva trapping device includes a trunk sleeve 1, with an adhesive trapping assembly at the top of the trunk sleeve 1. The adhesive trapping assembly includes: an insect trap 101, which is installed on the top of the trunk sleeve 1; a kit 102, which is fixedly connected to the side surfaces of the trunk sleeve 1 and the insect trap 101; a support rod 103, which is installed inside the kit 102; and a double-sided adhesive layer 104, which is adhered to the inner side of the insect trap 101. The device works by using the adhesive trapping assembly... When used together, the double-sided adhesive layer 104 can trap larvae that have fallen from the tree, preventing them from climbing back up or finding a suitable habitat. As a result, the larvae become trapped, unable to move, and die, greatly reducing their chances of survival and reproduction. When a large number of larvae are trapped on the double-sided adhesive layer 104, the double-sided adhesive layer 104 can be torn off from the inner surface of the trap 101 and replaced with a new double-sided adhesive layer 104. Replacing the double-sided adhesive layer 104 with a new one ensures capture efficiency, as the new adhesive layer is stronger and can trap larvae more effectively.

[0022] like Figures 2-3 As shown, a retaining ring 201 is fixedly connected to the outer surface of the trunk sleeve 1, and a fastening bolt 202 is threaded inside the retaining ring 201. Through the cooperation of the retaining ring 201 and the fastening bolt 202, it can be ensured that the trunk sleeve 1 can be firmly fixed to the trunk, preventing the trunk sleeve 1 from loosening or falling off due to external forces or wind, thus ensuring its effective operation. At the same time, the fastening bolt 202 can easily adjust the tightness of the trunk sleeve 1, or easily disassemble and reinstall it when needed, and install it to suit trunks of different diameters.

[0023] like Figures 2-3 As shown, the inner side of the trunk sleeve 1 is provided with anti-slip grooves 3. The anti-slip grooves 3 are horizontally opened, and there are several anti-slip grooves 3, which are evenly distributed on the inner side of the trunk sleeve 1. The trunk sleeve 1 is made of elastic material. The anti-slip grooves 3 increase the friction between the trunk sleeve 1 and the trunk, preventing the trunk sleeve 1 from sliding or loosening on the surface of the trunk, effectively improving the stability of the trunk sleeve 1, so that it can stay in the correct position for a long time and avoid frequent adjustments or reinstallation. At the same time, the elastic material of the trunk sleeve 1 can provide a more uniform contact surface between the trunk sleeve 1 and the trunk, reducing friction damage caused by direct contact. In this way, the bark will not be compressed or torn due to excessive friction.

[0024] like Figure 1 As shown, bait 4 is provided on the surface of the double-sided adhesive layer 104. The bait 4 is evenly distributed on the surface of the double-sided adhesive layer 104. The bait 4 can attract target insects and increase their chances of contacting the surface of the double-sided adhesive layer 104, thereby improving the capture efficiency.

[0025] like Figure 2As shown, there are several supporting curved rods 103, which are evenly distributed on the side surfaces of the trunk sleeve 1 and the insect trap 101. Under the action of multiple supporting curved rods 103, the insect trap 101 can be stably supported, and the supporting curved rods 103 can be bent at will. Thus, the curvature of the supporting curved rods 103 can be adjusted according to the site conditions. When the curvature of the supporting curved rods 103 is larger, the opening area of ​​the insect trap 101 is larger, thereby improving the insect-catching efficiency.

[0026] like Figure 2 As shown, the insect trap 101 is attached in a ring shape with Velcro. To make it easy to wrap the insect trap 101 around the surface of the tree trunk, it can be attached around with Velcro, and it is also easy to roll up the insect trap 101.

[0027] The working principle of this utility model is as follows: When it is necessary to capture larvae, the trunk sleeve 1 can be wrapped around the surface of the trunk first, and the insect trap 101 can be opened and supported by the support rod 103. When the larvae fall from the tree, they will automatically fall into the inside of the opened insect trap 101, and the larvae will be stuck and captured on the surface by the adhesive layer 104. This can effectively prevent larvae that attempt to climb back up the tree after falling, prevent them from re-infecting the tree, and reduce the larvae's reproduction opportunities. This helps to cut off a key link in the pest's life cycle and reduce the spread of pests.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
