Description

Technical Field

[0001] This invention relates to the field of agricultural pest control technology, and more specifically, to an ornamental rapeseed flower cabbage white butterfly dynamic control device and its usage method. Background Technology

[0002] Ornamental rapeseed boasts advantages such as vibrant colors, long flowering period, and high economic benefits, making it a superior crop for boosting rural industrial revitalization. However, the cabbage white butterfly larvae (cabbage white butterfly larvae) damages rapeseed leaves and buds, with leaf loss rates reaching up to 90% in severe cases. This hinders rapeseed growth and development, reducing its ornamental value and economic worth, and severely restricting the development of the ornamental rapeseed industry. Traditional single-method pest control, such as chemical, biological, and physical control, all have numerous drawbacks. Chemical control easily causes environmental pollution and reduces the number of natural enemies. In particular, the safe interval for most chemical pesticides is more than 3 days, and in areas with frequent tourist activity, such as urban landscapes and agricultural tourism parks, pesticide residues may pose a potential threat to human health. Furthermore, biological control methods, such as applying Bacillus thuringiensis and Beauveria bassiana microbial agents and releasing natural enemies, as well as physical control methods, such as manual capture and setting up insect-proof nets, are all subject to environmental constraints. For large-scale planting of ornamental rapeseed, these methods not only consume a lot of manpower and resources but also have limited control effects.

[0003] While the ornamental rapeseed industry is booming, rapeseed pest control faces numerous challenges. These challenges primarily stem from an insufficient understanding of the Integrated Pest Management (IPM) concept, reliance on simplistic control methods, a lack of equipment capable of integrated pest management, and the misconception that pests must be completely eradicated. Although equipment combining two control methods, such as pheromone-based dual-trap devices, exists on the market, these devices are still designed for pest elimination and are unsuitable for controlling pests in ornamental rapeseed. The ornamental value of rapeseed comprises both flower viewing and butterfly attraction. Therefore, it is crucial to control the cabbage white caterpillar within the control threshold to maximize the number of adult cabbage white butterflies and generate greater socio-economic benefits. Currently, ornamental rapeseed fields primarily rely on chemical and biological control to reduce cabbage white caterpillar damage and artificially breed cabbage white butterflies for release during the flowering season to attract tourists. This method is costly and time-consuming; therefore, the development of innovative devices and methods that simultaneously control larval cabbage white caterpillars and regulate adult cabbage white butterfly populations is urgently needed.

[0004] Based on the rhythmic differences between the larval cabbage white caterpillar (nocturnal) and the adult cabbage white butterfly (diurnal), this invention utilizes the "push-pull" theory of integrated pest management to provide an efficient, environmentally friendly, and sustainable ornamental rapeseed flower-cabbage white butterfly dynamic control device, which has significant practical implications. Summary of the Invention

[0005] The purpose of this invention is to provide a dynamic control device for ornamental rapeseed flowers and cabbage white butterflies and its usage method, so as to solve the problem that the existing ornamental rapeseed cannot simultaneously achieve "flower viewing" and "butterfly appreciation". At night, it reduces damage by repelling cabbage white caterpillars and increases the number of rapeseed flowers; during the day, it attracts cabbage white butterflies by using sex pheromones or traps made from natural plant extracts, thereby improving the ornamental value while dynamically controlling the cabbage white butterfly population. This implements the "IPM" integrated pest management concept, achieving efficient and environmentally friendly control of pests on ornamental rapeseed, while also being easy to operate and reducing labor intensity.

[0028] The following is in conjunction with the appendix Figure 1-6 The present invention will be described in further detail below.

[0029] Example: An ornamental rapeseed flower and cabbage white butterfly dynamic control device and its usage method, such as Figures 1-6 As shown, the device includes a vertically arranged column 2, with a horizontal crossbar 4 and a second crossbar 11 above the first crossbar 4. A collection mechanism 5 and a trap storage tank 12 are mounted on the first crossbar 4. A trapping mechanism 6 is mounted above the collection mechanism 5 and is installed on the second crossbar 11. The trap storage tank 12 contains a special trapping agent for common pests of ornamental rapeseed. This trapping agent is made from pheromones or natural plant extracts, is environmentally friendly, and effectively enhances the attraction to pests. The trapping tank 12 is connected to the trapping mechanism 6 via a flexible hose 16. A pump is installed on the trapping tank 12 to atomize the trapping agent, which is then dispersed through the hose 16 from the trapping mechanism 6 to attract cabbage white butterflies and their larvae. A mounting block 3 is fixedly connected to the bottom of the column 2. The bottom of the column 2 is equipped with a burial block 1, and the mounting block 3 is detachably connected to the burial block 1 by screws. After determining the installation location of the device in the rapeseed planting area, the burial block 1 and the mounting block 3 are buried in the soil to install the device. The attractant storage tank 12 is made of corrosion-resistant plastic material with a volume of 5L, and the flexible hose 16 is a plastic pipe with an inner diameter of 8mm. The attractant is a mixture of natural volatile substances extracted from plants such as mint and lavender in a certain proportion.

[0030] The trapping mechanism 6 includes a horn-shaped outer shell 69, a top cover 61, and a base 65. The base 65 is located in the middle of the horn-shaped outer shell 69, and several connecting rods 66 connect the base 65 and the horn-shaped outer shell 69. The top cover 61 is located above the base 65 and is connected to the second crossbar 11. A protective shell 62 connects the top cover 61 and the horn-shaped outer shell 69, and a notch is provided on one side of the protective shell 62. Attracted rape pests and the like enter the trapping mechanism 6 through the notch in the protective shell 62. A trapping lamp 63 is provided on the top of the base 65, and a high-voltage electrode mesh 64 surrounds the top outer side of the base 65. The outer side of the horn-shaped outer shell 69 is provided with a connecting ear plate 68, which connects to the collection mechanism 5. The two ends of the connecting rods 66 are fixedly connected to the horn-shaped outer shell 69 and the base 65, respectively. A large gap is left between the horn-shaped outer shell 69 and the base 65, and rape pests and the like, after being attracted and electrocuted, fall through the gap into the collection mechanism 5. The trapping lamp 63 uses a special wavelength light source to attract a variety of pests. The high-voltage electrode mesh 64 is made of stainless steel wire. The trapping lamp 63 is an LED trapping lamp, emitting a light source with a wavelength of 300nm-400nm, which has a strong attraction to a variety of pests.

[0031] The base 65 is further configured as follows: the base 65 is hollow inside and has several air holes 610 at its top that communicate with the interior; one connecting rod 66 is also hollow inside, with one end connected to the interior of the base 65 and the other end passing through the flared outer shell 69 to form a connection port 67 that connects to the hose 16. The atomized attractant enters the base 65 through the hose 16, diffuses into the protective shell 62 through the air holes 610 at the top of the base 65, and is released into the air through the opening in the protective shell 62, attracting rapeseed white butterflies and other pests to enter the protective shell 62 through the opening, where they are electrocuted by the high-voltage electrode mesh 64.

[0032] The collection mechanism 5 is further configured as follows: A housing 51 is included, with a movable door 52 on its side. A connecting ear plate 53 extends through the top of the housing 51 and is detachably connected to the trapping mechanism 6 via screws. A collection bucket 54 is located inside the housing 51. Cabbage white butterflies and other pests killed by the high-voltage electrode mesh 64 fall from the top of the housing 51 into the collection bucket 54. The collection bucket 54 of the collection mechanism 5 is removed periodically to clean and disinfect the dead pests.

[0033] The device is further configured as follows: a repellent mechanism 7 and a repellent storage tank 13 are mounted on the crossbar 11. The repellent storage tank 13 is connected to the repellent mechanism 7 by a flexible hose 17. The repellent mechanism 7 includes a housing 71. Inside the housing 71, a heating plate 72 is located at the bottom, and a heating tank 73 is located on the heating plate 72. A booster pump 74 is located at the top inside the housing 71. The booster pump 74 is connected to the heating tank 73 by an air guide pipe 75. A connecting pipe 15 is located at the top of the housing 71 and connected to the booster pump 74. A nozzle 8 is located at the distal end of the connecting pipe 15. The repellent is selected as nitrous oxide or a new type of agent that has been experimentally verified to be effective against cabbage caterpillars and is environmentally friendly. The repellent storage tank 13 is made of a corrosion-resistant material with excellent sealing performance to ensure long-term stable storage and safe use of the agent. The repellent storage tank 13 is equipped with a pump that can quantitatively deliver the repellent into the heating tank 73 for heating, further vaporizing and volatilizing the repellent. After being pressurized by booster pump 74, the vaporized repellent is sprayed out through nozzle 8 and dispersed around the rapeseed plants to form a protective barrier and repel pests that are active at night.

[0034] Further configuration includes: a control box 14 mounted on column 2, housing a battery, a light sensor, a pest density sensor, and a controller; the controller includes a circuit board with a microprocessor, a photoresistor for the light sensor, and an infrared sensor for the pest density sensor. The light sensor detects changes in ambient light intensity, and the controller switches between different operating modes during the day and night. All system components are precisely assembled to ensure tight connections and no loosening or leakage. The installation process strictly adheres to electrical safety regulations, with insulation and securing of the wiring. After assembly, basic information such as the geographical coordinates of the rapeseed planting area, planting area, and expected flowering period are input into the controller. Based on local historical meteorological data and the biological habits of the cabbage white butterfly, the controller presets operating modes and parameters. For example, during the spring and summer months when days are long and nights are short, the daytime trapping time is appropriately extended, and the frequency of nighttime repellent evaporation is increased; in autumn, as temperatures drop and cabbage white butterfly activity slows, the system's operating intensity and time intervals are adjusted accordingly, achieving intelligent and personalized operation of the device.

[0035] Further configuration: The top of the column 2 is provided with a mounting rod 9, and the far end of the mounting rod 9 is provided with a solar panel 10. The electrical energy converted by the solar panel 10 is stored in a battery for powering the entire device. When supplying power to the high-voltage electrode grid 64, the released electrical energy is converted from the input voltage to a suitable high voltage output through a small transformer and then connected to the high-voltage electrode grid 64.

[0036] The method of using the ornamental rapeseed flower and cabbage white butterfly dynamic control device provided by this invention is as follows:

[0037] S1: Install the dynamic control device in the ornamental rapeseed planting area, determine the installation location and quantity, check that all parts are firmly connected, turn on the power, and carry out installation and debugging. Set the initial parameters such as the brightness of the trapping lamp 63, the voltage of the high-voltage electrode mesh 64, the release amount of the trapping agent, and the release amount of the repellent agent, and adjust the sensitivity of the light sensor and the pest density sensor.

[0038] S2: During the day, when the light sensor detects strong light, the trapping lamp 63 automatically turns off. If the pest density sensor detects that the pest density exceeds the set threshold, the controller controls the release of the trapping agent in the trapping agent storage tank. In the evening, when the light sensor detects that the light is weak, the trapping lamp 63 automatically turns on, and the trapping agent is continuously released. When pests approach the trapping lamp 63, they enter through the opening on one side of the protective shell 62 and touch the high-voltage electrode mesh 64, where they are electrocuted and fall into the collection mechanism 5. The controller automatically adjusts the brightness of the trapping lamp 63, the voltage of the high-voltage electrode mesh 64, and the amount of trapping agent released based on the pest density sensor data.

[0039] S3: At night, the light sensor detects the light intensity and sends a signal to the controller, activating the repellency mechanism 7; the heating plate 72 moderately heats the repellent in the heating tank 73, causing it to vaporize and evaporate; the booster pump 74 pressurizes the gasified repellent and sprays it out through the nozzle 8 to spread it around the rapeseed plants, forming a protective barrier to repel pests active at night.

[0040] S4: Regularly check the working status of each part of the device, remove the collection bucket 54 of the collection mechanism 5 every once in a while to clean the insect corpses and disinfect it, regularly check the remaining amount of the bait storage bucket 12 and the repellent storage bucket and replenish the bait and repellent, and regularly clean and maintain the solar panel 10.
