Description

Technical Field

[0001] This utility model relates to the field of experimental instruments for insect chemical ecology, and in particular to a device for studying visual behavior selection experiments of small and medium-sized insects. Background Technology

[0002] Based on insect chemical ecology, in order to reduce or replace chemical pesticides in my country's agricultural production, the development of physical control technologies such as highly efficient insect-attracting color boards has become an important trend in the green control of agricultural pests and has broad application prospects.

[0003] By utilizing insects' sensitive visual system, this study explores their color-attracting behavior in response to different wavelengths of light, providing a scientific data foundation for developing efficient color-trapping technology for agricultural pests.

[0004] Currently, both domestic and international insect visual behavior selection devices have varying degrees of limitations. For example, traditional visual behavior selection devices cannot be folded or rotated, and adding or removing individual light source activity chambers is relatively cumbersome, requiring custom-made solutions that are time-consuming and labor-intensive. Furthermore, traditional devices can only screen insects' preferences for different wavelengths of light during experiments, and cannot simultaneously screen insects' preferences for different colors. Utility Model Content

[0005] In view of this, the present invention provides a device for studying visual behavior selection experiments of small and medium-sized insects, which aims to solve the limitations of light source wavelength and color in the existing technology for studying the visual behavior of insects. It enables multiple insects to be released at one time to conduct visual behavior selection experiments on different wavelengths of light sources or different colors. During the test, as long as there is a white light source, different colored light sources can be obtained through the transmission of light, which reduces costs and increases the reliability of research data.

[0006] To achieve the above characteristics, the technology adopted by this utility model is as follows:

[0007] An apparatus for studying visual behavior selection experiments in small and medium-sized insects includes a lower base plate, an upper base plate, and an insect light source activity chamber.

[0008] Preferably, the lower base plate and the upper base plate are rectangular transparent acrylic sheets.

[0009] Preferably, the lower base plate consists of a chassis, a base, and a bottom shaft, wherein the central axis of the bottom shaft is connected to the chassis, and the central shaft seat is connected to the base, so as to realize the free rotation of the chassis.

[0010] Preferably, the upper base plate has a rectangular entrance in the middle and is equipped with a circular entrance cover, which allows for the preparation of insects before the experiment begins.

[0011] Preferably, the insect light source activity chamber is composed of multiple individual light source activity chambers of different colors, and the light source activity chambers are rectangular boxes made of PVC material of different colors.

[0012] Preferably, the colors of all sides of each individual light source activity chamber constituting the insect light source activity chamber are uniform.

[0013] Preferably, the bottom surface of each individual light source activity chamber that makes up the insect light source activity chamber is transparent to facilitate data statistics after the behavioral experiment.

[0014] Preferably, each of the individual light source activity chambers constituting the insect light source activity chamber has connecting ears on both sides, namely, a first connecting ear to the right side and a second connecting ear to the right side, so as to achieve a tight connection of multiple individual light source activity chambers of different colors, and at the same time, they can be combined with each other at different angles in the horizontal direction.

[0015] Preferably, a PVC baffle is added at the connection between the bottom surface and the upper side of the single light source activity chamber. This baffle is the same color as the single light source activity chamber and the same size as the upper side of the activity chamber. It can be flipped up and down around the connection point to ensure uniform distribution of light sources during the visual behavior selection test of insects. At the end of the phototaxis test, the baffle is opened and the chassis is rotated to collect data through the bottom surface of the activity chamber.

[0016] Preferably, when selecting different wavelength light sources, the single light source activity chamber is made of white transparent material, and the activity chamber baffle has an opening in the middle, which is axial with one side of the rectangle and can be opened and closed freely. In a dark environment, combined with LED lights of different wavelengths, the selection of light sources with insect preferred wavelengths can be achieved.

[0017] The beneficial effects of this utility model are as follows:

[0018] This device overcomes the limitations of traditional visual behavior selection experiments, enabling the screening of insect preferences for different wavelengths of light and different colors. Furthermore, the individual light source chambers can be flexibly combined according to the actual experimental design, and their positions can be randomly changed during repeated experiments to reduce the randomness of the experiment. Data can be collected by rotating the base for observation and counting. The device is novel in design, low in cost, and simple to operate, making it suitable for visual behavior selection experiments on most small and medium-sized insects.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] To address the technical problems in the background section, the following apparatus is provided for studying visual behavior selection experiments in small and medium-sized insects:

[0028] Combination Figures 1-3As shown, this utility model provides a device for studying visual behavior selection experiments of small and medium-sized insects, including a lower base plate 1, an upper base plate 2, and an insect light source activity chamber 3. The lower base plate 1 and the upper base plate 2 are rectangular transparent acrylic plates. The lower base plate 1 consists of a base plate 101, a base 102, and a bottom shaft 103. The central shaft 1031 of the bottom shaft 103 is connected to the base plate 101, and the central shaft seat 1032 is connected to the base 102 to allow the base plate 101 to rotate freely. The upper base plate 2 has a rectangular entrance 201 in the middle and is equipped with a circular entrance cover 202, which can facilitate the experiment. Before the experiment, the insects were prepared. The insect light source activity chamber 3 consisted of multiple individual light source activity chambers 301 of different colors. Each light source activity chamber was a rectangular box made of PVC material in a different color. The four sides of each individual light source activity chamber 301 were of a uniform color, and the color included, but was not limited to, any color corresponding to a light wavelength within the range of 380-780nm. The bottom surface of each individual light source activity chamber 301 was transparent to facilitate data collection after the behavioral experiment. The light source chamber 301 has connecting ears on both sides: a first connecting ear 302 and a second connecting ear 303, to achieve a tight connection of multiple individual light source chambers 301 of different colors. They can also be combined horizontally at different angles. A PVC baffle 304 is added at the connection between the bottom surface 3015 and the upper side surface 3011 of each individual light source chamber 301. This baffle is the same color and size as the individual light source chamber 301 and is used for connection. With the axis as the center, it can be flipped up and down to ensure uniform distribution of light sources during visual behavior selection tests of insects. At the end of the phototaxis test, the activity chamber baffle 304 is opened, and the chassis 101 is rotated to collect data through the bottom surface 3015 of the activity chamber. When screening different wavelength light sources, the single light source activity chamber 301 is made of white transparent material. The activity chamber baffle 304 has an opening 305 in the middle, which can be opened and closed freely with the axis as the rectangle. In the dark environment, it is combined with LED lights of different wavelengths to achieve the screening of light sources with insect preference wavelengths.

[0029] Working principle and usage process of this utility model:

[0030] In use: Before conducting insect visual behavior selection experiments, multiple individual light source activity chambers 301 are assembled into a single insect light source activity chamber 3. First, connect adjacent activity chambers by connecting right-side hook 1 302 and activity chambers by connecting right-side hook 2 303. During connection, insert and fix the two opposite-oriented activity chamber connecting hook openings 1 3021 and 2 3031. At this time, the connected individual light source activity chambers can be moved freely in the horizontal direction. The angle between them is determined by the number of individual light source activity chambers assembled. Place the lower base plate 1, then place the assembled insect light source activity chamber 3 on the lower base plate 1, and then cover it with the upper base plate 2. Keep the activity chamber baffle 304 of the individual light source activity chamber 301 closed. At this time, the opening 305 of the activity chamber baffle remains closed. Before the insect to be tested is placed into the insect light source activity chamber 3, the circular entrance cover 202 of the upper base plate 2 is opened, and the insect is placed in through the rectangular entrance 201. The white light source is turned on, and through the principle of light transmission, the insect light source activity chamber 3 will display different colors, thus completing the insect's attraction to different colors. When the experiment ends, the activity chamber baffle 304 of the individual light source activity chamber 301 is opened for counting. The transparent bottom surface 3015 of the activity chamber facilitates data collection. The rotating base 101 allows for data collection of each individual light source activity chamber 301, avoiding errors caused by shaking the insect light source activity chamber 3. For experiments on insect attraction behavior to different light wavelengths, multiple individual light source activity chambers 301 can be connected together, ensuring the activity chamber baffle openings 305 on the activity chamber baffles 304 of each individual light source activity chamber remain open. By using LEDs of different wavelengths, phototaxis behavior tests can be conducted, setting different time periods to check the number of insects in each individual light source activity chamber 301, thus completing the insect visual behavior selection experiment. After the behavioral test, all insects in the experimental device must be removed, and the interior of each individual light source activity chamber 301 must be thoroughly cleaned.
