[0043] The setting of the camera device 2 realizes automatic monitoring of the behavior of the cotton aphid, without the need for long-time manual observation, so that the efficiency of data acquisition is improved, and errors caused by human factors are avoided.

[0044] The plurality of sheet bodies 5 arranged around the aphid placement area can place cotton leaf blades of different varieties at the same time, facilitating comparison of the attraction of different cotton leaf blades to cotton aphids, and meeting diversified test requirements. The overall structure of the device is reasonably designed, relatively simple to operate, is conducive to large-scale cotton aphid resistance bias identification test, and provides reliable data support for the cultivation of cotton aphid-resistant varieties.

[0062] The upper cavity is mainly used for placing the temperature and humidity sensor 3 and the temperature and humidity adjusting device 4, facilitating centralized control and monitoring of environmental parameters. The partition plate 7 is used for placing the sheet 5 and forming the aphid placement area, facilitating test operation.

[0063] The partition plate 7 made of transparent material does not affect lighting and observation.

[0064] The camera 2 and the spectrum lamp 6 are arranged in the upper cavity and the lower cavity, realizing multi-angle observation of the behavior of cotton aphids, avoiding observation dead angles, and being capable of more comprehensively recording behavior information of cotton aphids, thereby providing more abundant data for research on cotton resistance to cotton aphid bias.

[0069] Through the mutual attraction of the first magnetic sheet 8 and the second magnetic sheet 9, the sheet 5 is firmly fixed on the partition 7. This magnetic attraction fixing method is simple and convenient. When the sheet 5 needs to be replaced, it can be easily removed by gently pulling. During the test, the sheet 5 can be stably placed on the partition 7 and will not be displaced due to external factors such as slight vibration and air flow, ensuring the accuracy and stability of the test. At the same time, the magnetic attraction fixing method can also flexibly adjust the position and number of the sheet 5 according to the test requirements, improving the flexibility and adaptability of the device.

[0070] In another aspect, the cotton variety resistance to cotton aphid bias test device, the top edge of each piece of sheet 5 embedded in a third magnetic sheet 10, the third magnetic sheet 10 and the first magnetic sheet 8 are separated by a certain distance and do not interfere with each other.

The other end of each handle 12 is away from the corresponding sheet 5, and a support block 13 is provided at the bottom of each handle 12. The bottom of each support block 13 is in contact with the top of the partition 7.

[0071] The handle 12 makes it easier to replace the sheet 5. By attracting the fourth magnetic sheet 11 and the third magnetic sheet 10, the sheet 5 can be easily picked up and put down. The design of the attraction force ensures that the sheet 5 can be easily removed from the partition 7 when replacing the sheet 5, while the sheet 5 can be firmly fixed on the partition 7 during the test. The support block 13 at the bottom of the handle 12 stabilizes the sheet 5, preventing the handle 12 from shaking or tilting due to uneven force, ensuring the safety and stability of the operation.

[0075] The aphid placement area is arranged in the middle of the partition plate 7, which can ensure that the external interference of cotton aphids when selecting cotton leaves on different pieces 5 is relatively uniform. In this way, the selection behavior of cotton aphids is more natural and random, and the attractiveness of different cotton leaves to cotton aphids can be more accurately reflected. At the same time, the arrangement of the middle position is also convenient for the surrounding pieces 5 to be distributed in a ring shape, which is beneficial to improve the efficiency and comparability of the test. In the process of test operation, the middle position is convenient for placing and taking out cotton aphids, which improves the convenience of the test.

[0076] The use method of the test device for identifying the cotton variety resistance to cotton aphid bias is as follows:

[0077] Preparation work:

[0078] Leaf preparation: Select cotton leaves of different varieties as test materials, and fix them on 9 or 12 transparent pieces 5 with handles 12, and the piece numbers are A1, A2, A3; B1, B2, B3; C1, C2, C3, etc. These pieces 5 are stacked in layers when not in use, and when in use, they can be pulled out to the same plane through the handle 12. The first magnetic sheet 8 embedded at the bottom edge of the piece 5 is attracted to the corresponding second magnetic sheet 9 on the partition plate 7, so that the piece 5 carrying the cotton leaves is stably placed on the partition plate 7. The fourth magnetic sheet 11 at one end of the bottom of each handle 12 is attracted to the third magnetic sheet 10 at the top edge of the piece 5, which is convenient for operation.

[0079] Aphid placement: Put an appropriate amount of cotton aphids in the aphid placement area with a diameter of about 5-8 cm in the middle of the partition plate 7, and ensure that the aphid placement area and the pulled-out piece 5 are in the same plane.

[0080] Equipment debugging: Check the connection of each part of the device to ensure that the camera device 2, the temperature and humidity sensor 3, the temperature and humidity adjusting device 4, the light spectrum lamp 6, the controller, the image processing module, the liquid crystal display screen and other equipment are working normally. Set the temperature and humidity adjusting device 4 through the controller to set the temperature to 17-28℃ adjustable range and the relative humidity to 50-70%.

[0082] Start the device and record the initial data: turn on the device, the camera 2 starts real-time shooting, and cooperates with the image processing module to automatically count the number of cotton aphids on each piece 5 (i.e. each leaf). The temperature and humidity sensor 3 transmits the temperature and humidity data in the box 1 to the controller and displays the current temperature, humidity and the initial number of aphids on each piece 5 on the LCD screen, records these initial data, and provides a basis for subsequent analysis.

[0083] Continuous observation and data collection: during the test, researchers can directly observe the behavior of cotton aphids through the observation port on the cover 101, the transparent box 1 and the partition 7, and also can observe cotton aphids from multiple angles by using the camera 2 and the spectrum lamp 6 in the upper and lower cavities. The controller monitors the temperature and humidity in real time and adjusts the temperature and humidity adjusting device 4 as needed to ensure that the environment is stable within the set range. The image processing module continuously processes camera data and updates the number of aphids on each piece 5 in real time. Researchers record the data on the LCD screen at regular intervals and observe the selection, feeding and movement of cotton aphids on different numbered pieces 5 (corresponding to different cotton leaves). As the test progresses, when aphids tend to feed on certain materials, the change in the number of aphids on the display screen will reflect this situation in real time.

[0084] Data processing and analysis:

[0085] Data export: after the test, export the temperature and humidity data from the controller and the number of aphids on different numbered pieces 5 at different time periods from the image processing module.

[0086] Statistical analysis: use professional data statistical analysis software to calculate the mean, standard deviation, etc. of the number of aphids on each numbered piece 5 at different time periods, and perform significance difference test. Combine the observation and recording of cotton aphid behavior, analyze the data, and draw conclusions on the attractiveness of different numbered pieces 5 (i.e. different cotton varieties) to cotton aphids, which provides a basis for cotton aphid-resistant variety breeding.

[0087] Device cleaning and maintenance:

[0088] Clean the components: remove the cotton leaves on the pieces 5 and the remaining cotton aphids in the aphid placement area and properly dispose of them. Use a damp cloth to wipe the inside of the box 1, the partition 7, the pieces 5 and other components to remove impurities and aphid secretions. Fold up the pieces 5 through the handle 12 and stack them in layers.

[0089] Check the equipment: check the connection and working condition of each equipment, if the camera 2, temperature and humidity sensor 3, temperature and humidity adjusting device 4 and other equipment are found to be faulty, repair or replace them in time to ensure that the device can be used normally next time. At the same time, check whether the LCD screen display is normal and whether the spectrum lamp 6 can emit light normally.
