Description

Technical Field

[0001] This utility model relates to the technical field of green mirid bug prediction devices, and in particular to a predictor of the occurrence pattern of green mirid bugs in tea gardens. Background Technology

[0002] The green mirid bug, belonging to the order Hemiptera and family Miridae, primarily damages spring tea and is prevalent in northern tea-growing regions. In spring, the larvae of the green mirid bug infest tea buds. After the fresh tea leaves are fed on, black, necrotic spots appear at the affected areas, later developing into irregular holes as the buds and leaves unfold. This can even cause leaf margins to crack, and the leaves to become twisted and wrinkled, resulting in deformed or coarse young leaves. Tea made from these infested leaves has a bitter taste, affecting both yield and quality. Severely affected tea gardens can experience yield reductions of over 70% in spring tea. Therefore, during tea cultivation, it is essential to predict and forecast the occurrence of green mirid bugs and implement scientific control measures to mitigate their damage.

[0003] To predict and forecast the occurrence of pests such as the green mirid bug, existing technologies in tea gardens often employ the method of setting up sticky traps with attached or applied sex pheromones. Sticky traps are a simple and practical physical control tool, typically placed in various corners of the tea garden. Sex pheromones are special chemical substances that mimic the sex pheromones released by female green mirid bugs, attracting males. In practice, workers count the number of pests on the sticky traps within a specified time period. Analysis of this data allows for accurate determination of the timing and severity of the infestation. For example, if the number of green mirid bugs on the sticky traps suddenly increases within a certain timeframe, it can be inferred that this is the peak breeding season for green mirid bugs, requiring appropriate control measures.

[0004] However, existing forecasting methods also have significant limitations. Currently, pheromone traps are usually directly attached to the back of sticky insect traps. This fixed placement method makes it impossible to effectively regulate the evaporation rate of the pheromone traps. The evaporation rate of the pheromone traps has a crucial impact on their insect-attracting effect. If the evaporation rate is too fast, the pheromone traps may evaporate completely in a short time, failing to continuously attract pests and significantly reducing the control effect; if the evaporation rate is too slow, they may continue to evaporate even when insect attraction is not needed, resulting in waste of the pheromone traps. Moreover, when the pheromone traps are not in use, they cannot be turned off, and they will continue to emit odors, which not only attracts unwanted pests but may also have a certain impact on the surrounding ecological environment. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the existing technology by providing a predictor of the occurrence pattern of green stink bugs in tea gardens, thereby controlling the volatilization rate of sex pheromones and improving their utilization rate.

[0022] like Figure 1 and 2 As shown, this utility model includes a main support 1 and a sex attractant volatilization mechanism 2.

[0023] The upper end of the bracket is equipped with a sex pheromone volatilization mechanism 2, and the upper end of the sex pheromone volatilization mechanism 2 is equipped with a sticky insect board 3.

[0024] like Figure 3 As shown, the sex attractant evaporation mechanism 2 includes a receiving cylinder 21, an upper sealing end cap 28, a lower sealing end cap 26, a partition 24, and a drainage cotton swab 22. The receiving cylinder 21 has a cavity with an upper opening. The upper part of the cavity of the receiving cylinder 21 is provided with a partition 24. The partition 24 is provided with a plurality of mounting sleeves 25 evenly distributed in a circumferential shape. The mounting sleeves 25 are provided with through holes distributed along the axis. The upper end of the drainage cotton swab 22 is inserted into the through hole of the mounting sleeve 25, and the lower end is inserted into the cavity of the receiving cylinder 21.

[0025] A lower sealing end cap 26 is installed at the cavity opening of the container 21. The lower sealing end cap 26 is placed above the partition 24 and rotates with the container 21. An upper sealing end cap 28 is installed above the lower sealing end cap 26 and fits into the lower sealing end cap 26. The upper sealing end cap 28 and the lower sealing end cap 26 are respectively provided with a plurality of circumferentially evenly distributed vent holes. When the vent holes of the upper sealing end cap 28 and the lower sealing end cap 26 overlap, the pheromone in the container 21 evaporates the fastest. When the vent holes of the upper sealing end cap 28 and the lower sealing end cap 26 are alternately closed, the container 21 is closed.

[0026] A sticky insect plate 3 is installed on the upper end of the upper sealing cap 28. The sticky insect plate 3 has multiple small through holes to facilitate the evaporation of the pheromone through the through holes. In this embodiment, the back of the sticky insect plate 3 is attached to the upper sealing cap 28.

[0027] like Figure 5 As shown, in the optimized scheme, a connecting rod 23 is fixedly installed at the middle position of the bottom wall of the receiving cylinder 21, and a through hole is provided at the center position of the partition 24 and the lower sealing end cover 26. The upper end of the connecting rod 23 passes through the through hole of the partition 24 and the lower sealing end cover 26 in sequence and is fixedly connected to the upper sealing end cover 28.

[0028] The connecting rod 23 has a blind hole with an upper opening at its axis, and a through hole on the outer wall of its lower end. The through hole at the lower end of the connecting rod 23 communicates with the blind hole at its axis. A sealing plug 29 is installed at the opening of the blind hole of the connecting rod 23. When it is necessary to inject a sex attractant into the receiving cylinder 21, the sex attractant is injected into the receiving cylinder 21 through the opening at the upper end of the connecting rod 23.

[0029] like Figure 4As shown, the outer side of the lower sealing end cap 26 is fixedly connected to the rotating sleeve 27.

A limiting pin is installed on the inner wall of the rotating sleeve 27, and an arc-shaped guide groove is provided on the outer wall of the receiving cylinder 21. The limiting pin 271 is placed in the arc-shaped guide groove. When the rotating sleeve 27 drives the limiting pin 271 to rotate to one end of the arc-shaped guide groove, the vent holes of the upper sealing end cap 28 and the lower sealing end cap 26 coincide. When the rotating sleeve 27 drives the limiting pin 271 to rotate to the other end of the arc-shaped guide groove, the vent holes of the upper sealing end cap 28 and the lower sealing end cap 26 are staggered and closed.

[0030] The main support 1 is connected to the photovoltaic panel 5 and the camera 6 via a connecting frame 4. The photovoltaic panel 5 and the camera 6 are located above the pheromone evaporation mechanism 2. The lens of the camera 6 faces the sticky insect board 3 and is parallel to it. A battery is installed on the main support 1. The battery is connected to the photovoltaic panel 5 and the camera 6 via a circuit. The battery can power the camera 6, which can take pictures of the sticky insect board 3, thereby allowing analysis of the pictures to determine the number of green mirid bugs. The circuit described is existing technology, and its specific structure will not be described in detail.

[0031] In the optimized solution, the upper end of the connecting frame 4 is hinged to one end of the connecting plate 7. The connecting frame 4 and the connecting plate 7 are connected by a telescopic rod 9. One end of the telescopic rod 9 is hinged to the connecting frame 4, and the other end is hinged to the connecting plate 7. When the telescopic rod 9 extends or retracts, it can drive the connecting plate 7 to rotate.

[0032] In this embodiment, the telescopic rod 9 is a hydraulic telescopic rod or an electric telescopic rod.

[0033] The upper end of the connecting plate 7 is fixedly connected to the photovoltaic panel 5, and a hinge seat is fixedly installed on the lower end face of the connecting plate 7. An ear plate is fixedly installed on the upper end of the camera 6, and the ear plate is hinged to the hinge seat. The camera 6 is connected to the connecting frame 4 through a hinge rod 8. One end of the hinge rod 8 is hinged to the camera 6, and the other end is hinged to the connecting frame 4. The connecting frame 4, the connecting plate 7, the camera 6, and the hinge rod 8 form a parallelogram structure. When the telescopic rod 9 drives the connecting plate 7 to rotate, the lens of the camera 6 can always remain parallel to the sticky insect board 3.

[0034] The operation procedure is as follows: When using this utility model, fix the sticky insect board 3 on the upper sealing end cap 28, rotate the rotating sleeve 27, adjust the overlap of the air vents of the lower sealing end cap 26 and the upper sealing end cap 28, and the pheromone will be drawn out and evaporated by the drainage cotton swab 22 to attract green mirid bugs to the position of the sticky insect board 3. By observing the number of green mirid bugs on the sticky insect board 3, a prediction alarm can be made.

[0035] It should be noted that the specific embodiments of this utility model have been described in detail. For those skilled in the art, all obvious changes made to it without departing from the spirit and scope of this utility model are within the protection scope of this utility model.
