Description

Technical Field

[0001] This utility model relates to the field of agricultural pest control technology, specifically to a ground trapping device for tomato leafminer moth. Background Technology

[0002] The tomato leafminer, native to South America, is a global quarantine pest that causes devastating damage to the tomato industry. Its larvae burrow into tomato leaves, stems, and fruits, feeding and creating winding tunnels. This not only directly disrupts photosynthesis in the leaves, weakening the plant, but more seriously, it can directly bore into the fruit, causing reduced fruit quality, loss of commercial value, and even total crop failure. Furthermore, the tomato leafminer is characterized by its high reproductive rate, overlapping generations, and strong concealment, making control extremely difficult. Currently, the control of the tomato leafminer mainly relies on chemical pesticides. However, long-term and frequent use of chemical pesticides easily leads to problems related to the 3Rs (recycling, recycling, and environmental protection), which runs counter to the current advocacy of green and sustainable agricultural development. Therefore, seeking environmentally friendly integrated management strategies has become an urgent need for the industry's development.

[0003] In green pest control technologies, pheromone trapping is widely used due to its advantages such as high specificity, no harm to natural enemies, and no pesticide residues. This technology uses artificially synthesized sex pheromones to simulate the mating signals released by female moths, attracting male moths to a specific device and capturing them, thereby interfering with their normal mating and reducing the population density of the next generation. However, existing leafminer trapping devices still have many shortcomings in practical applications. Traditional simple devices (such as boat-shaped traps and triangular traps) have low trapping efficiency, while devices designed such as CN222929077U have complex structures, are inconvenient to use, and affect farmers' enthusiasm for using them.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. Additional aspects and advantages of this utility model will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the utility model. It should be understood that the following description is merely illustrative and not intended to limit the utility model.

[0019] The specific embodiments of this utility model are described in detail below.

[0020] Please see Figure 1This embodiment provides a ground trapping device for tomato leafminer, including a shell having a base plate 1 and a top plate 2, two support members 3 fixedly installed between the base plate 1 and the top plate 2, a blue plate 4 pasted on the upper surface of the top plate 2, and a lure 5 pasted on the blue plate 4.

[0021] The shell has a three-dimensional triangular prism structure with side openings and is made of plastic. The base plate 1 and the top plate 2 are the same size, and the base plate 1 is placed on the ground. The angle between the base plate 1 and the top plate 2 is 30°. This embodiment uses a base plate 1 with dimensions of 52cm*26.5cm as an example for explanation.

[0022] The support member 3 is vertically arranged, and two support members 3 are horizontally arranged on both sides. The support member 3 is made of iron wire, and corresponding small holes are opened on the sides of the base plate 1 and the top plate 2. The iron wire is tied between the base plate 1 and the top plate 2 through the small holes. In this embodiment, based on the connecting function of the support member 3, the base plate 1 and the top plate 2 maintain an included angle of 30°, which makes the shell structure stable and can better resist field airflow and rainwater.

[0023] In this embodiment, taking advantage of the tomato leafminer adult's strong attraction to blue, the blue board 4 and the lure 5 are used together to better trap male tomato leafminers. The lure 5 is a porous carrier that adsorbs the female tomato leafminer's pheromone. This embodiment uses a rubber lure 5 as an example. The porous structure slows down the diffusion rate of pheromone molecules, thereby prolonging the pheromone release period and achieving continuous release of the female tomato leafminer's pheromone.

[0024] Blue board 4 provides a sticky surface to capture attracted male tomato leafminers. The sticky surface is coated with a strong sticky adhesive. Both the strong sticky adhesive and the female tomato leafminer pheromone involved in this embodiment are commercially available. The male tomato leafminers attracted by blue board 4 and lure 5 are stuck in the strong sticky adhesive, thereby achieving the purpose of trapping and controlling tomato leafminers.

[0025] In summary, the trapping device of this embodiment has the following advantages: simple structure, low cost, convenient use and replacement, large contact area between the tomato leafminer and the sticky insect surface, and the combination of the tomato leafminer's flight as a dynamic movement in three-dimensional space with the device structure, and the design of a trapping structure at a 30° angle to the ground, which improves the trapping efficiency.

[0026] The trapping device of this embodiment will be used below, such as... Figure 2 planar traps, such as Figure 3 The three types of traps—triangular traps, triangular traps, and triangular traps—were used in trapping experiments in controlled indoor environments, warm greenhouse environments, and cold greenhouse environments, respectively.

[0027] The controlled indoor trapping experiment was conducted in an open laboratory with strictly controlled environmental conditions: temperature 25±2℃, relative humidity 60±5%, and light cycle 16L:8D. This environment was designed to eliminate external variables and accurately evaluate the structural performance of the traps themselves. The traps were randomly arranged at 2m intervals and three repeated experiments (T1, T2, T3) were conducted, each lasting 72 hours. The cumulative number of traps captured by each trap was recorded, and the results are shown in Table 1.

[0028] Table 1. Performance comparison of traps in controlled indoor environments (unit: traps) T1 24 63 5 T2 36 67 3 T3 35 53 2 average value 31.67±3.84b 61±4.16a 3.33±0.88c In Table 1, different letters indicate significant differences (p < 0.05).

[0029] Analysis of Table 1 shows that the trapping device designed in this embodiment has a significantly higher average trapping capacity than all other control structures (p < 0.05), demonstrating the superiority of the inclined surface design of the trapping device in this embodiment. Based on this, the trapping effect at different tilt angles was further tested. The test objects were 0° (i.e., the top plate 2 covers the base plate 1, and the blue plate 4 is placed horizontally), 30° (in this embodiment), 60° (i.e., the angle between the base plate 1 and the top plate 2 is 60°, and the blue plate 4 is placed at a 60° tilt), and 90° (i.e., the angle between the base plate 1 and the top plate 2 is 90°, and the blue plate 4 is placed vertically). The test method was the same as above, and three repeated experiments were conducted. The results are shown in Table 2.

[0030] Table 2 Comparison of the number of animals captured by traps at different angles (unit: animals) T1 58 69 37 26 T2 40 71 19 24 T3 42 66 31 21 average value 46.67±5.70b 68.67±1.45a 29±5.29c 23.67±1.45d In Table 2, different letters indicate significant differences (p < 0.05).

[0031] As shown in Table 2, the trapping device with a 30° tilt angle performed best, with its average trapping rate being significantly higher (p < 0.05) than that of other angles. The aforementioned test results further demonstrate the superiority of the trapping device in this embodiment.

[0032] The trapping experiment in a greenhouse environment was conducted in a well-sealed tomato growing greenhouse. Three types of traps were evenly placed in the greenhouse at a spacing of 5m. The trapping was monitored for several weeks, and the number of traps was recorded once a week. The results are shown in Table 3.

Comparison of trap performance under greenhouse conditions (unit: traps) T1 105±4.04c 135±2.08b 312±3.53a T2 151±3.51b 68±5.69c 219±18.43a T3 100±2.89b 123±6.66b 212±18.78a T4 110±7.64b 101±6.66b 198±23.39a Table 4. Comparison of trap performance in cold greenhouse environment (unit: traps) T1 80±3.5c 230±9.28b 365±25.23a T2 98±2.0c 242±19.86b 344±26.28a T3 145±6.51b 124±13.09b 290±13.92a T4 136±10.12b 160±19.41b 288±12.33a In Tables 3 and 4, different letters indicate significant differences (p < 0.05). The trapping experiment results in Tables 1 to 4 prove that the trapping device of this embodiment can achieve efficient trapping of tomato leafminer, which is beneficial for pest control in greenhouse and polytunnel planting areas and has excellent prospects for promotion.
