[0020] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0021] In order to make the above-mentioned purposes, features and advantages of the present application more apparent, clear and understandable, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0022] Referring to Figures 1-5 As shown in the drawings, the present embodiment provides a device for carrying out selection preference function test, which comprises an upper shell 1, a lower shell 2 detachably connected below the upper shell 1, a support column 4 fixedly connected to the center of the inner bottom surface of the lower shell 2, a plurality of baffles 5 radially detachably connected to the support column 4, the side of the baffle 5 away from the support column 4 being attached to the inner wall of the lower shell 2, a through hole 3 being formed in the center of the top surface of the upper shell 1, and a cotton strip 7 being detachably connected at the through hole 3, honey water being added to the cotton strip 7 for parasitic bees to feed on.

[0023] The parasitic bees or predatory insects are loaded from the through hole 3, facilitating the carrying out of the test, the lower shell 2 being divided into a plurality of cavities by the baffles 5, facilitating the carrying out of selection function test of two or more than two hosts, the honey water being added to the cotton strip 7 to provide food for the parasitic bees; the upper shell 1 and the lower shell 2 being detachably connected by a buckle structure, facilitating the carrying out of the test. The present application can more simply complete the selection preference test, and can reduce errors due to instruments and operations, so that the experimental data is more reliable and rigorous. Since the materials used in the entire experimental device are ordinary common materials, the cost is not high, and the entire experimental device can be detached, when some small components are not needed in the experiment, it can be detached, at the same time, the baffles 5 can be assembled into the lower shell 2, that is, the selectivity of two pairs or more than two pairs of hosts can be carried out, the operation steps of the experiment are simplified, the problem of repeated operation caused by instruments can be avoided, the workload in the experimental process is reduced, and the experimental efficiency is improved.

[0024] The buckle structure is usually used for the embedded connection or integral locking of one part to another. Its composition mainly includes the following two key parts: positioning part: the main function of the positioning part is to guide the buckle to reach the predetermined installation position smoothly, correctly and quickly during installation. It ensures that the buckle can accurately align and connect two parts, thereby ensuring the stability and reliability of the connection. Fastener: the fastener is another important component of the buckle structure. It is responsible for firmly connecting two parts together. Depending on the requirements, the fastener can be divided into two types: detachable and non-detachable. Detachable fastener: this type of fastener is designed to detach the buckle after applying a certain separation force, and the two connected parts are separated. This design allows the connected parts to be easily disassembled and reassembled, suitable for parts that need to be frequently disassembled. Non-detachable fastener: this type of fastener requires manual deflection or destruction of the fastener to detach the two parts. It is mainly used for parts that do not need to be disassembled during use to ensure the durability and stability of the connection.
