Description

Technical Field

[0001] This utility model belongs to the field of insect behavior science, specifically relating to an automatic observation device for insect feeding and oviposition selection preferences. Background Technology

[0002] In current technology, all ways in which insects interact with the outside world are manifested through various behaviors. In-depth research on insect behavior can provide important basis for insect breeding, biological control, ecophysiological research, and classification. Among the basic behavioral patterns of insects, feeding behavior is of great significance in terms of individual insect survival, population reproduction, environmental adaptation, and pest control. Therefore, the study of insect feeding behavior is an indispensable part of insect behavioral research.

[0003] Chinese Patent Publication No. CN209152040U discloses a device for detecting insect feeding trends. It primarily addresses the problem of the lack of effective devices for detecting insect feeding trends currently available on the market. This invention provides a device for detecting insect feeding trends, in which insects are placed in a main container, and different attractant materials are placed in a secondary container.

[0004] In the aforementioned patent, the top of the main container is opened or closed using a single lid. When a large number of insects are placed in the main container, they are prone to escape when the lid is closed. Furthermore, the feeding preferences of the insects in the aforementioned patent need to be monitored manually. This method requires prolonged observation or frequent intervention, which can easily trigger stress responses in the insects, leading to behavioral distortions such as interrupted feeding and affecting the final experimental results.

[0005] In addition, the aforementioned devices have difficulty detecting the number of insects that repeatedly select feeding sites (mainly small flying insects), affecting data accuracy; at the same time, they lack regulatory mechanisms to adapt to different developmental stages of insects (such as larvae and adults) and differences in individual size. Utility Model Content

[0006] To overcome the shortcomings of existing technologies, this utility model provides an automatic observation device for insect feeding and oviposition preferences, which solves the technical problems such as insect escape during the testing process, difficulty in identifying returning insects during the testing process, and difficulty in monitoring insects returning at different developmental stages.

[0007] To achieve the above objectives, the specific technical solution of this utility model is as follows: An automated observation device for insect feeding and oviposition preferences includes a test chamber body, an insect chamber assembly, and a dynamic monitoring assembly. The test chamber body comprises multiple independent preference testing units. Each preference testing unit is equipped with a fluorescent food trough.

[0008] The insect chamber assembly includes an insect chamber and multiple insect passageways disposed on the outer wall of the insect chamber. The outer ends of each insect passageway are connected to a respective preference testing unit.

[0009] The dynamic monitoring component includes a support bracket, multiple infrared cameras, and multiple infrared counters. Each infrared camera is mounted on the upper support bracket and corresponds to a preference testing unit. Each infrared counter is located at the exit of each insect passageway.

[0010] Furthermore, the preference testing units are connected end-to-end in sequence to form a box structure with an open center. The insect chamber assembly is located within the central open area.

[0011] Furthermore, each of the insect passageways is equipped with a sealing plug to close or open the entrance to the insect passageway.

[0012] Furthermore, the insect box includes a lower chamber body and an upper movable cover. The chamber body is an open-top structure. The top of the chamber body has a stepped mounting edge. The outer ring of the movable cover is embedded within the mounting edge.

[0013] Furthermore, the top of the movable cover plate has an insect release opening. A sealing cap is embedded in the insect release opening. Rivets are fixed to the top surface of the sealing cap.

[0014] Furthermore, a limiting member is provided at the edge of the insect inlet. The limiting member is rotatably connected to the movable cover plate and can move into or away from the area above the insect inlet during rotation.

[0015] Furthermore, the exits of each of the insect passageways are coated with fluorescent dyes of different colors.

[0016] Furthermore, each of the aforementioned preference testing units includes an inner frame plate, an outer frame plate, a top plate, and two partition walls. The two partition walls are glued to the side edges of the inner and outer frame plates, respectively. The top plate is positioned on top of the partition walls, forming a closed trapezoidal box structure together with the inner and outer frame plates.

[0017] Furthermore, a plant access port is provided on the outer frame panel. A movable door panel is installed on the plant access port.

[0018] Furthermore, the support bracket includes a bracket body disposed around each preference testing unit, and multiple sliding rods arranged sequentially on the bracket body. Each sliding rod corresponds to one preference testing unit. Each infrared camera is slidably connected to its corresponding sliding rod.

[0019] Compared with the prior art, the present invention has the following advantages: 1. This utility model involves embedding a movable cover plate within the top of the chamber body. A small insect-introducing opening is provided on the movable cover plate, allowing researchers to select the size of the opening as needed. This facilitates cleaning and operation inside the chamber while preventing insects from escaping when placed inside.

[0020] 2. This invention utilizes infrared cameras positioned around each testing unit and infrared counters installed within each insect passageway. This allows researchers to compare the data recorded by both systems, reducing the impact of insects turning back on the experiment. Furthermore, the use of fluorescent food troughs of different colors allows researchers to visually observe the insects' feeding behavior, further minimizing the impact of insects turning back after feeding.

[0021] 3. This invention places different colored fluorescent dyes in each insect passageway and in the fluorescent food trough. When conducting experiments with larger reptiles, the fluorescent dyes in each insect passageway can be used to remove crawling individuals. When conducting experiments with flying or smaller insects, the colors in the fluorescent food trough can be used to remove crawling individuals, thus meeting the experimental needs of different types of insects.

[0024] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper side", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figure 1 and 2 As shown, an automatic observation device for insect feeding and oviposition preferences includes a test chamber body, an insect chamber assembly, and a dynamic monitoring assembly. The test chamber body comprises multiple independent preference testing units 1. Each preference testing unit 1 is equipped with a fluorescent food trough 15 to distinguish the feeding results of the tested insects. The preference testing units 1 are connected end-to-end to form a box structure with an open center. The insect chamber assembly is located within the central open area.

[0027] The insect chamber assembly includes an insect chamber 5 and multiple insect passageways 3 disposed on the outer wall of the insect chamber 5. The outer ends of each insect passageway 3 are connected to a preference testing unit 1, thereby connecting the inner cavity of the insect chamber 5 with the preference testing unit 1.

[0028] The dynamic monitoring component is located on the periphery of the test chamber body and is used to monitor the dynamics of the tested insects inside the test chamber body.

[0029] like Figure 3 and 6 As shown, in this embodiment, each insect passage 3 is equipped with a sealing plug 8, which is used to close or open the entrance of the insect passage 3. The experimenter can open a corresponding number of insect passages 3 according to the experimental needs.

[0030] Furthermore, the exits of each insect passageway 3 are coated with fluorescent dyes of different colors to help researchers eliminate insects that crawl into the corresponding preference test unit 1, turn back, and reselect the test subjects.

[0031] like Figure 2 and 3As shown, the insect box 5 includes a lower chamber body and an upper movable cover 6. The chamber body is an open-top structure. The top of the chamber body has a stepped mounting edge. The outer ring of the movable cover 6 is embedded within the mounting edge and can be removed before experiments, facilitating the removal of the sealing plug 8 at the insect passage 3 entrance. When conducting experiments on the feeding preferences of the insects being tested, the movable cover 6 is installed on the top of the chamber body.

[0032] like Figure 4 As shown, the top of the movable cover 6 has an insect inlet 10. A sealing cap 11 is embedded in the insect inlet 10 to close or open it. Researchers can place the insects to be tested into the insect box 5 through the insect inlet 10, avoiding the possibility of the insects escaping if the movable cover 6 is completely removed during placement, resulting in an excessively large opening in the insect box 5.

[0033] In this embodiment, a rivet 12 is fixed on the top surface of the cap 11, which makes it easy for the experimenter to remove the cap 11 from the insect inlet 10 when it is in the embedded state.

[0034] Furthermore, a limiting member 9 is provided at the edge of the insect inlet 10. The limiting member 9 is rotatably connected to the movable cover 6 and can move into or away from the upper area of ​​the insect inlet 10 during rotation. When the limiting member 9 moves into the upper area of ​​the insect inlet 10, it can limit the cover 11 embedded in the insect inlet 10, preventing the tested insect from opening the cover 11 and escaping. When the experiment is completed, the experimenter rotates the limiting member 9 away from the upper area of ​​the insect inlet 10. The cover 11 can then be easily removed from the insect inlet 10.

[0035] like Figure 1 and 5 As shown, each preference testing unit 1 includes an inner frame panel, an outer frame panel, a top panel, and two partition panels. The two partition panels are glued to the side edges of the inner and outer frame panels respectively. The top panel is placed on top of the partition panels, forming a closed trapezoidal box structure together with the inner and outer frame panels.

[0036] In this embodiment, a plant access port is provided on the outer frame panel. A movable door panel 2 is installed on the plant access port for closing or opening the plant access port. During the experiment, the experimenter opens the movable door panel 2, places the test plant 7 into the corresponding preference test unit 1, and closes the movable door panel 2 after placement.

[0037] like Figure 1 and 5As shown, the dynamic monitoring component includes a support bracket, multiple infrared cameras 13, and multiple infrared counters 4. The support bracket includes a main body surrounding each preference testing unit 1, and multiple sliding rods 14 arranged sequentially on the main body. Each sliding rod 14 corresponds to one preference testing unit 1. Each infrared camera 13 is slidably connected to its respective sliding rod 14, allowing it to rise or fall along the rod 14 under manual control, thus enabling monitoring and adjustment of the preference testing unit 1 at different angles. Each infrared counter 4 is located at the exit of each insect passageway 3, used to record the number of insects entering the corresponding preference testing unit 1.

[0038] Furthermore, each infrared camera 13 has a slide at its tail end. The infrared camera 13 is slidably connected to the slide rod 14 via the slide. A through threaded hole is provided on the slide. A locking screw is threaded into the threaded hole to lock or release the slide. When the slide needs to slide, the locking screw is turned outward to move it away from the slide rod 14. The slide can then slide freely on the slide rod 14. When the slide reaches a specified height, the locking screw is tightened inward to abut against the slide rod 14. The static friction between the locking screw and the slide rod 14 locks the height of the slide.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
