[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0022] An embodiment of this utility model: A device for rapidly screening the oviposition preferences of the bean leaf borer, comprising a box body 1, four mounting ports 2 evenly distributed on the bottom plate of the box body 1, an oviposition cup 3 provided at each mounting port 2, a notch 5 provided on the side wall of the box body 1 directly above each oviposition cup 3, the bottom of the notch 5 being flush with the inner surface of the bottom plate of the box body 1 and its width being greater than the width of the mounting port 2, four openings evenly distributed on the bottom side wall of the box body 1, a pull-out sugar source supply box 4 movably disposed at each opening, and a blocking plate 6 that can be inserted into the box body 1 through the notch 5 and covers the mounting port 2.

[0023] In use, the test insects are placed into the box 1. Each of the four corners of the bottom of the box 1 has a sugar source supply box 4, designed to be pull-out, allowing for direct replacement of the sugar source without opening the box 1, thus preventing the test insects from flying out. At the bottom of the box 1, there is a leaf-shaped dish at the bottom of the oviposition cup 1. Volatile substances or cotton balls soaked in sugar source can be placed on the leaf-shaped dish. The oviposition cups 1 are arranged in a ring around the center of the bottom of the box 1, ensuring that the test insects are not influenced by distance when making their selection. Under the influence of the substances in the oviposition cups 1, the test insects will crawl towards their preferred oviposition cup 1 to lay their eggs. When it is necessary to remove the oviposition cup 1 from the mounting port 2, first insert the blocking plate 6 into the box 1 through the notch 5. Since the bottom of the notch 5 is flush with the inner surface of the bottom plate of the box 1 and its width is greater than the width of the mounting port 2, the inserted blocking plate 6 can effectively and completely block the mounting port 2, preventing the test insects from escaping from the mounting port 2 when the oviposition cup 1 is removed. Removing the oviposition cup 1 allows different substances to be placed inside, enabling multiple sets of selection preference experiments, and also facilitates the counting of eggs laid on the oviposition cup 1.

[0024] Each mounting port 2 has a threaded connection to an oviposition cup 3, which facilitates the installation and removal of the oviposition cup 3.

[0025] The side wall of the box 1 is also provided with ventilation holes 7 to allow air circulation inside and outside the box 1, ensuring the normal activity of the test insects inside the box 1.

[0026] The box 1 has an open top and a lid 8 on top. The test insects can be placed inside the box 1 by opening the lid 8. The lid 8 can be removed to clean the box 1.

[0027] The box 1 and the oviposition cup 3 are made of transparent material, which makes it easy to observe the activity of the test insects inside the device.

[0028] The bottom of the box 1 is provided with a support leg 9. The height of the support leg 9 is greater than the height of the egg-laying cup 3. The support leg 9 supports the box 1 while making it easy to reach into the bottom of the box 1 to install and remove the egg-laying cup 3.

[0029] A placement box 10 is also provided on the outer wall of the box body 1. When the baffle 6 is not in use, it is placed in the placement box 10 to avoid it being easily lost if placed randomly.

[0030] This invention discloses a device for rapidly screening the oviposition preferences of the bean leaf borer. Equipped with multiple sets of oviposition cups 3, it supports multiple oviposition experiments and facilitates the screening of oviposition-preferred substances (such as volatile substances or sugar sources). The oviposition cups 3 are detachable, making it easy to count daily oviposition or replace corresponding substances. Furthermore, the modular structure facilitates maintenance and expansion, making it suitable for various experimental scenarios. This device will provide an efficient and standardized tool for biological research on the bean leaf borer and integrated pest management in agriculture, providing a scientific basis for agricultural production and pest control.
