[0002] Western flower thrips ( Frankliniella occidentalis This is a globally prevalent and dangerous pest with a very wide host range, capable of damaging vegetables, flowers, and various field crops. The insect is tiny, reproduces rapidly, and is highly secretive, often hiding in flowers and tender shoots to feed on the plants. It not only directly affects crop growth but also transmits various plant viruses, causing severe economic losses.

[0003] Currently, the control of western flower thrips still relies excessively on chemical pesticides.

[0035] Example

[0036] This embodiment provides a method for controlling western flower thrips using a synergistic attraction and trapping effect of solar red-blue composite light, including the following steps: S1. Deploy control devices at preset intervals in the target field area, and select areas with high crop planting density and severe damage from western flower thrips as deployment points; S2. Fix the support device 3 in the field and adjust the height of the main support rod 3.2 so that the lighting attraction device 1 is located 20-30cm above the crop canopy; S3. The blue sticky insect board 2.3 is suspended on the support rod 1.3 around the lighting attraction device 1 by thin iron wire 2.2, and the suspension height is level with the tender shoots of the crop; S4. Set the switch control box 1.6 to "time control mode" to automatically turn on the red and blue light sources from sunset to sunrise the next day and turn them off during the day; The S5.1 solar panel stores electricity during the day, using a smart controller to store it in a 12V / 24Ah battery, which powers the red and blue LED chips at night. Actual test data shows that under 6 hours of effective sunlight per day, a fully charged battery can support continuous LED chip operation for 5-7 days, meeting emergency prevention and control needs during prolonged periods of cloudy or rainy weather. The red LED chip has a wavelength of 625nm, and the blue LED chip has a wavelength of 470nm. Each chip has a power of 0.5W, and the entire lamp consumes ≤6W, making it energy-efficient and highly effective. S6. Western flower thrips attracted by red and blue composite light come into contact with blue sticky insect board 2.3 during flight and are trapped, achieving efficient trapping at night; S7. During the day, blue sticky traps 2.3 are used to continuously physically trap the western flower thrips in the activity; S8. Regularly inspect and replace the sticky insect boards, clean the dust and obstructions from the surface of the rain shelter 1.5 and solar panels 1.1 to ensure photoelectric conversion efficiency; check the battery power and controller status to ensure continuous and stable system operation.

[0037] Application Example 1

[0038] The experimental site was selected as the open-field cultivation experimental field behind Yunnan Agricultural University (25.04°N, 102.71°E). To verify the adaptability of the solar power supply system, this area has a subtropical monsoon climate with significant differences in sunlight throughout the four seasons and concentrated rainfall and frequent continuous rainy weather in summer. The test aimed to optimize the photoelectric conversion efficiency by adjusting the tilt angle and test the endurance stability under continuous rainy weather, providing data support for large-scale field application in Yunnan. The experiment covered all four seasons, with continuous monitoring for 30 days in each season, and complete recording of data for different weather periods (with a focus on tracking performance under continuous rainy weather in summer). The tilt angle of the solar panels was adjusted according to the solar altitude angle of different seasons in this area (referencing measured data from the Yunnan Provincial Meteorological Bureau) (30° in spring, 20° in summer, 30° in autumn, and 50° in winter) to maximize the reception of sunlight. The test indicators included the average daily photoelectric conversion efficiency, the average daily battery charge, the endurance under continuous rainy weather, and the stability of power supply.

[0039] The results of this experiment show that the system has good adaptability in the open-field cultivation experimental field behind Yunnan Agricultural University: after tilt angle adjustment in different seasons, the photoelectric conversion efficiency reached the design standard (≥22%). In spring, at a 30° tilt angle, the average daily efficiency was 23.8%, and the battery charging time was 13.5 Ah; in summer, at a 20° tilt angle to adapt to strong sunlight, the efficiency was 22.3%, and the charging time was 12.7 Ah; in autumn, at a 30° tilt angle to match sunny weather, the efficiency reached 24.5% (the best of the year), and the charging time was 14.3 Ah; in winter, at a 50° tilt angle to compensate for insufficient sunlight, the efficiency was 22%, and the charging time was 11.8 Ah. This verifies the adaptability value of tilt angle adjustment to seasonal sunlight conditions (e.g., ...). Figure 4 (As shown in Table 1). During the continuous rainy season test, after 5 days without effective sunlight, the battery, fully charged (24Ah), had a remaining capacity of 3.8Ah, exceeding the LED operating threshold (3Ah), providing a 5-day battery life and meeting the design requirement of "stable power supply for 3-5 days of continuous rainy weather". During the 120-day monitoring period throughout the year, the system operated without faults for up to 24 hours, with the LEDs turning on and off stably on and off on time, demonstrating that this solar power system provides reliable data support for the large-scale field application of the device.

[0041] Application Example 2

[0042] The experimental site was a tomato open-field cultivation experimental field behind Yunnan Agricultural University to verify the field control effect of the device of this invention. The treatment of this invention used a combination of red light wavelength 625nm and blue light wavelength 470nm, with the blue sticky insect boards suspended at the same height as the tomato flower spikes. The device was set up at a spacing of 10m × 10m, with three replicates per treatment. Controls included no light source with only blue sticky insect boards, red and blue light only without blue sticky insect boards, and no control measures. On days 7, 14, and 21 after the start of the experiment, the number of adult western flower thrips in each treatment area was investigated. Sticky insect boards were suspended at five points in each sampling area. After 24 hours, the boards were covered with plastic wrap and brought back to the laboratory where the number of western flower thrips and the female-to-male ratio were recorded under a microscope. Simultaneously, 20 tomato plants were randomly surveyed in each area, and the number of live thrips on the flowers and tender shoots was recorded.

[0043] The control effect of this invention on western flower thrips is significantly better than other treatments. Referring to Table 2, throughout the entire 21-day test period, the number of western flower thrips detected in the treatment group of this invention was consistently the lowest, at 35.33 thrips / plate on day 7, 20.33 thrips / plate on day 14, and 12.00 thrips / plate on day 21, and significantly lower than the treatments without control (CK), red and blue light only, and blue sticky trap only. The results indicate that the control method provided by this invention not only has good immediate effect but also has continuous pest control capabilities.

[0045] Note: Data in the table are mean ± standard error. Different lowercase letters in the same row indicate significant differences in the population size of western flower thrips under different treatments on the same day (LSD test). P <0.05).

[0046] The comparison of western flower thrips populations on tomato plants (Table 3) showed significant differences in control efficacy among treatments (P<0.05). Throughout the 21-day experiment, the number of thrips on plants without control (CK) continuously increased, reaching 59.33 thrips / plant on day 21; the number of thrips on plants treated with only red and blue light was 33.33 thrips / plant on day 7 and 24.00 thrips / plant on day 21; the number of thrips on plants treated with only blue plaster was 26.00 thrips / plant and 15.67 thrips / plant; while the number of western flower thrips on plants treated with this invention remained the lowest, at 13.67 thrips / plant on day 7, 8.67 thrips / plant on day 14, and 6.00 thrips / plant on day 21, significantly lower than other treatments. The results indicate that this invention can effectively reduce the western flower thrips population on plants, possessing a sustained and highly efficient control capability.

[0048] Note: Data in the table are mean ± standard error. Different lowercase letters in the same row indicate significant differences in the population size of western flower thrips under different treatments on the same day (LSD test). P <0.05).

[0049] This invention analyzed the effects of different treatments on the sex ratio of western flower thrips populations on blue sticky traps and tomato plants. At the three observation points of day 7, 14, and 21, the number of male and female western flower thrips in the treatment group of this invention was lower than in other treatments, and the number of male and female western flower thrips in each treatment group showed a decreasing trend over time. Throughout the experiment, the number of male and female western flower thrips in the no-control (CK) treatment was consistently the highest, followed by the red-blue light treatment and the blue trap treatment, while the number of male and female western flower thrips in the treatment group of this invention was consistently the lowest (e.g., ...). Figure 5 (As shown in the figure); the results show that the treatment of the present invention can effectively regulate the population structure of western flower thrips, significantly reduce the number of male and female individuals, and has a good and sustainable pest control effect.

[0050] The above experimental results demonstrate that the western flower thrips control device and method proposed in this invention, which utilizes solar-powered red-blue composite light for synergistic attraction and trapping, is significantly more effective than traditional methods that rely solely on red-blue light or simply hanging blue sticky traps in controlling western flower thrips in the field. This invention combines a lighting attraction device with a specific wavelength combination (620-630nm red light and 465-475nm blue light) with blue sticky traps, and integrates a high-efficiency solar power supply system (conversion efficiency ≥22%, 3-5 days of continuous operation), an adjustable tilt structure (15°-60°), and IP65 protection design. This achieves continuous day-and-night attraction and control, energy self-sufficiency, and strong environmental adaptability, effectively reducing the number of western flower thrips on sticky traps and plants, and regulating their population sex structure, exhibiting continuous and efficient pest control capabilities.

[0051] This device is powered by solar energy and features intelligent time-controlled start / stop. It operates automatically according to the diurnal activity patterns of western flower thrips. The sticky trap's hanging height is adjustable, making it suitable for the control needs of different crop types. It exhibits good field adaptability and environmental friendliness. This invention provides an energy-saving, efficient, and easy-to-operate technical means for the green control of western flower thrips, helping to reduce the use of chemical pesticides and promoting integrated pest management and ecologically sustainable planting.

Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
