Description

Technical Field

[0001] This utility model belongs to the technical field of insect-attracting devices, specifically relating to an insect-attracting device for controlling pests and diseases in greenhouses. Background Technology

[0002] Current greenhouse pest and disease control mainly relies on chemical, physical, and biological methods. Among these, physical control offers advantages such as being environmentally friendly, pollution-free, highly efficient, sustainable, and less prone to resistance development. Utilizing the phototaxis and color-attraction of pests to lure and kill them is a common method in physical control. Greenhouse pest and disease control traps typically consist of yellow and blue sticky traps, supplemented with attractants.

[0003] Chinese utility model patent CN216701408U discloses a multifunctional support for trapping pests, which traps pests by placing yellow-blue sticky traps and attractant packets containing attractants. This method of trapping pests using yellow-blue sticky traps and attractant packets has certain limitations. In actual greenhouse production, poor air circulation limits the diffusion range of the active ingredients in the attractant packets, significantly restricting their effectiveness. Furthermore, at dusk or at night without light, the weak ambient light reduces the trapping effect of the yellow-blue sticky traps, further diminishing their effectiveness in actual greenhouse production. In actual greenhouse production, physical control and trapping devices mainly consist of black light lamps or yellow-blue sticky traps. Black light lamps emit ultraviolet and violet light waves of 330-400nm to attract insects. However, the attractiveness of black light lamps to insects decreases during the day or when the ambient light is strong, resulting in poor insect attraction. Yellow-blue sticky traps mainly utilize the color attraction of insects to attract them. For example, pests such as aphids, whiteflies, and leaf miners are strongly attracted to yellow, while pests such as thrips are more sensitive to blue. Yellow-blue sticky traps mainly rely on reflected light from the ambient light to attract insects. At night or when the ambient light is weak, the light reflected by the yellow-blue sticky traps is weak and fails to attract insects effectively. Utility Model Content

[0004] The purpose of this invention is to provide a greenhouse pest and disease control insect-attracting device, which solves the problem that existing insect-attracting devices in the background art cannot be used all day and are difficult to achieve the effect of attracting insects in environments with poor light.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A greenhouse pest and disease control device includes a hook, a chain, a support ring, a central ring, spokes, a yellow and blue plate, and a black light. The center lines of the central ring and the support ring are collinear. Four spokes are arranged at equal angles between the central ring and the support ring. The first end of each spoke is fixedly connected to the central ring, and the second end of each spoke is fixedly provided with a connecting ring. The connecting ring is slidably sleeved on the support ring. The yellow and blue plate is connected to the spoke by a fastener. The hook is located directly above the central ring. The hook and the support ring are connected by several chains. The first end of the chain is fixedly connected to the support ring, and the second end of the chain is fixedly connected to the hook. A guide ring is fixedly installed at the bottom of the hook. The black light is located at the center of the central ring. The wire of the black light is placed inside the guide ring. A through groove is opened on the guide ring. The wire passes through the through groove and is connected to an external power source. The center line of the guide ring and the center line of the central ring are collinear.

[0006] Preferably, the fastener is a spring clip or a strap.

[0007] Preferably, the number of chains is 3-5.

[0008] Preferably, the guide ring is provided with a locking structure.

[0009] Preferably, the locking structure is a locking bolt, which is threaded onto the side wall of the guide ring, and a washer is fixedly provided at the end of the locking bolt located inside the guide ring.

[0010] Preferably, the gasket is an arc-shaped piece.

[0011] Preferably, an anti-slip pad is provided on the concave surface of the arc-shaped piece.

[0012] Preferably, the diameter of the central ring is 5cm and the length of the spokes is 30cm.

[0013] Preferably, it also includes an adjusting strip, the two ends of which are provided with arc-shaped grooves, and the two arc-shaped grooves are respectively engaged on the central ring and the support ring.

[0014] Preferably, the number of adjustment strips is 2-5. The beneficial effects of this utility model are as follows: By combining the effects of black light lamps and yellow-blue sticky traps, and utilizing the phototaxis and color-taxis of pests, this method can achieve a highly efficient trapping effect under all weather conditions and varying light intensities. This improves upon the shortcomings of traditional insect traps in greenhouse production, where black light lamps become less attractive to insects during the day or in strong ambient light, and yellow-blue sticky traps are less effective in attracting insects in weak light or no light conditions. When the black light is turned on, it produces ultraviolet and violet light waves of 330-400nm that most insects prefer, which are more effective at attracting Lepidoptera and Coleoptera. Combined with the influence of the yellow and blue sticky board on the insects' color attraction and its stickiness, it is easier to stick insects to achieve a more efficient effect in controlling greenhouse pests and diseases. By using a hook in conjunction with a height-adjustable suspension device, the height can be adjusted according to different crops and different growth stages, so that it can have a good trapping effect on a variety of crops and at multiple stages. By setting up detachable adjustment bars, the number and angle of the yellow and blue boards can be adapted to different needs. Attached Figure Description

The first end of each spoke 6 is fixedly connected to the central ring 2, and the second end of each spoke 6 is fixedly provided with a connecting ring 4. The connecting ring 4 is slidably sleeved on the support ring 1. The yellow and blue plates 3 are connected to the spokes 6 by fasteners. The spokes 6 can rotate along the support ring 1, thereby adjusting the distribution angle of the yellow and blue plates. The hook 8 is located directly above the central ring 2. The hook 8 and the support ring 1 are connected by several chains 9. The first end of the chain 9 is fixedly connected to the support ring 1, and the second end of the chain 9 is fixedly connected to the hook 8. A guide ring 81 is fixedly installed at the bottom of the hook 8. The black light 7 is suspended at the center ring 2. The wire of the black light 7 is placed inside the guide ring 81. A through groove 83 is opened on the guide ring 81. The wire passes through the through groove 83 and is connected to an external power source. The center line of the guide ring 81 and the center line of the center ring 2 are collinear.

[0022] As a preferred example of the above embodiments, the spokes 6 and the connecting ring 4 are integrally formed.

[0023] As a preferred example of the above embodiments, the spokes 6 and the center ring 2 are welded together.

[0024] As a preferred example of the above embodiments, the fastener is a spring clip 5 or a strap, which facilitates quick replacement of the yellow and blue boards.

[0025] As a preferred example of the above embodiment, the number of chains 9 is 3 to 5, which provides good stability and avoids shaking caused by wind or insect impact.
