[0042] The following will be described in combination with Figures 1 to 7 The utility model discloses a two-way selection device for researching insect olfactory behavior.

[0043] According to the two-way selection device for insect olfactory behavior measurement provided by the embodiments of the present application, please refer to Figure 1 And Figure 2 The two-way selection device for insect olfactory behavior measurement includes a device main body, a first smell bottle 8, a second smell bottle 13 and a ventilation device, the device main body is provided with a first cavity 1, a first insect behavior observation room 2 and a second insect behavior observation room 3, the first cavity 1 is arranged between the first insect behavior observation room 2 and the second insect behavior observation room 3, the first cavity 1 is communicated with the first insect behavior observation room 2, and the first cavity 1 is communicated with the second insect behavior observation room 3;The first smell bottle 8 is connected with the first insect behavior observation room 2;The second smell bottle 13 is connected with the second insect behavior observation room 3;The ventilation device is connected with the first smell bottle 8 and the second smell bottle 13, for guiding the gas of the first smell bottle 8 into the first insect behavior observation room 2, and for guiding the gas of the second smell bottle 13 into the second insect behavior observation room 3.

[0044] The two-way selection device for insect olfactory behavior determination according to the embodiment of the application can form a stable airflow with consistent flow direction and uniform speed by arranging the first chamber 1, the first insect behavior observation chamber 2 and the second insect behavior observation chamber 3 on the same device main body, so as to ensure the stability of the wind speed in the process of determining the insect olfactory behavior reaction. The device can realize the olfactory behavior research and test of multiple insects at one time, reduces the time and manpower required by the research, improves the research efficiency, and reduces the research cost. The airflow speed in the insect behavior observation chamber and the first chamber 1 is low, so that the research and test of small and medium-sized insects or insects with weak flying ability can be effectively realized.

[0045] The two-way selection device for insect olfactory behavior determination according to the embodiment of the application can form a stable airflow with consistent flow direction and uniform speed by arranging the first chamber 1, the first insect behavior observation chamber 2 and the second insect behavior observation chamber 3 on the same device main body, so as to ensure the stability of the wind speed in the process of determining the insect olfactory behavior reaction. The device can realize the olfactory behavior research and test of multiple insects at one time, reduces the time and manpower required by the research, improves the research efficiency, and reduces the research cost. The airflow speed in the insect behavior observation chamber and the first chamber 1 is low, so that the research and test of small and medium-sized insects or insects with weak flying ability can be effectively realized.

[0046] It can be understood that the device main body bears the first chamber 1, the first insect behavior observation chamber 2 and the second insect behavior observation chamber 3, so that the device main body arranged as a whole can form a stable airflow with consistent flow direction and uniform speed, thereby ensuring the stability of the wind speed in the process of determining the insect olfactory behavior reaction.

[0047] The first chamber 1 is used for placing a certain number of test insects, thereby providing a starting point for the insects and enabling them to be in the same position at the beginning of the experiment. By concentrating the insects, it can be ensured that all the insects are in the same environmental conditions at the beginning of the experiment, thereby eliminating the influence of individual differences on the experimental results.

[0048] The first odor bottle 8 and the second odor bottle 13 are respectively connected to the first insect behavior observation chamber 2 and the second insect behavior observation chamber 3 and are used for placing an odor source and a blank control odor source. The two odor bottles are connected to the two observation chambers through the gas flow channel and are connected to the first chamber 1, so as to allow the odor material to flow to the insects. Through comparative experiments, the attractive behavior of insects to different odor sources can be clearly distinguished. The setting of the blank control odor source is helpful to eliminate the influence of other non-specific factors on the experimental results.

[0049] The gas flow channel formed by the first chamber 1, the first insect behavior observation chamber 2 and the second insect behavior observation chamber 3 allows the gas (including air and odor molecules) to flow inside the device, ensuring that the odor molecules can flow uniformly and stably to the insects, so that they can freely choose which insect behavior observation chamber to enter without disturbance.

[0050] The first odor bottle 8 and the second odor bottle 13 are containers for storing odor sources required for experiments, and can be connected to the corresponding insect behavior observation chambers through the connecting pipes. The ventilation device is a device for guiding the gas in the first odor bottle 8 and the second odor bottle 13 into the corresponding insect behavior observation chambers.

[0051] According to an embodiment of the present application, the bidirectional selection device for studying insect olfactory behavior includes a first movable partition 10 and a second movable partition 15. The first movable partition 10 is movably connected to the device body, and is arranged between the first chamber 1 and the first insect behavior observation chamber 2. The first movable partition 10 is provided with a first through hole, and the first through hole communicates the first chamber 1 and the first insect behavior observation chamber 2. The second movable partition 15 is movably connected to the device body, and is arranged between the first chamber 1 and the second insect behavior observation chamber 3. The second movable partition 15 is provided with a second through hole, and the second through hole communicates the first chamber 1 and the second insect behavior observation chamber 3.

[0052] It can be understood that the first movable partition 10 and the second movable partition 15 can be moved relative to the device body. The first movable partition 10 is provided with one or more first through holes, and the first through holes allow the gas (including odor molecules) to flow from the first chamber 1 to the first insect behavior observation chamber 2. In some embodiments, the first through holes allow the insects to pass through, so that the insects can enter the first insect behavior observation chamber 2 from the first chamber 1.

[0053] The movability of the first movable partition 10 allows the experimenter to replace the first movable partition 10 with different first through hole positions and sizes as needed, thereby ensuring that the concentration of odor molecules flowing to the insects is moderate and that the insects can pass through, improving the efficiency of the test.

[0054] Similarly, the second movable partition 15 is provided with one or more second through holes, and the second through holes allow the gas to flow from the first chamber 1 to the second insect behavior observation chamber 3. The movability of the second movable partition 15 allows the experimenter to replace the second movable partition 15 with different second through hole positions and sizes as needed, thereby ensuring that the concentration of odor molecules flowing to the insects is moderate and that the insects can pass through, improving the efficiency of the test.

[0055] It should be noted that the size, shape and position of the first and second through holes can be customized according to experimental needs. For example, they can be circular, square or other shapes, and can be set at different heights or angles as needed.

[0056] In one embodiment, the first and second through holes are circular holes with a diameter of 2 cm, allowing insects to fly / crawl into the first and second insect behavior observation chambers 2 and 3 from the first chamber 1.

[0057] According to one embodiment of the present application, the two-way selection device for studying insect olfactory behavior includes a third movable partition 11 and a fourth movable partition 16, the third movable partition 11 is movably connected to the device body and is arranged beside the first movable partition 10 for blocking the first through hole; the fourth movable partition 16 is movably connected to the device body and is arranged beside the second movable partition 15 for blocking the second through hole.

[0058] It can be understood that the third movable partition 11 is used to block or open the first through hole, thereby controlling the passage of gas (including odorant) from the first chamber 1 to the first insect behavior observation chamber 2, and the experimenter can flexibly control the opening and closing state of the first through hole.

[0059] The fourth movable partition 16 is similar to the third movable partition 11, and the fourth movable partition 16 is also a partition that can move relative to the device body. The fourth movable partition 16 can be used to block or open the second through hole, thereby controlling the passage of gas (including odorant) from the first chamber 1 to the second insect behavior observation chamber 3, and the experimenter can flexibly control the opening and closing state of the second through hole.

[0060] When precise control of odorant exposure or control experiments is required, the movability of the third and fourth movable partitions 11 and 16 provides a simple and effective method to block or open the gas flow passage, allowing the experimenter to more flexibly control experimental conditions, including the path, rate and exposure time of gas flow, thereby meeting a wider range of experimental needs.

[0061] According to one embodiment of the present application, the two-way selection device for studying insect olfactory behavior includes a movable door 7 movably connected to the device body to open and close the first chamber 1.

[0062] The movable door 7 is used to open and close or seal the first chamber 1, and can be connected to the device body by hinges, sliding rails or other connecting mechanisms to ensure that it can be smoothly and reliably opened and closed. The experimenter can easily open and close the first chamber 1, thereby facilitating the placement, removal of experimental samples, and cleaning and maintenance of the first chamber 1.

[0063] Further, a detachable cover 5 is provided above the first chamber 1, and the cover 5 is punched with a circular hole with a diameter of 2 mm, so as to ensure that the gas in the first chamber 1, the first insect behavior observation chamber 2 and the second insect behavior observation chamber 3 can flow uniformly.

[0064] According to one embodiment of the present application, the two-way selection device for studying the olfactory behavior of insects comprises a first movable cover plate 6 and a second movable cover plate 12, the first movable cover plate 6 is movably connected to the device body and is arranged at the top of the first insect behavior observation chamber 2, and the second movable cover plate 12 is movably connected to the device body and is arranged at the top of the second insect behavior observation chamber 3.

[0065] It can be understood that the first movable cover plate 6 and the second movable cover plate 12 are arranged at the top of the first insect behavior observation chamber 2 and the second insect behavior observation chamber 3 respectively, and the placement of the odor source can be controlled by controlling the opening and closing of the first movable cover plate 6 and the second movable cover plate 12, which is beneficial to operation.

[0066] According to one embodiment of the present application, the first insect behavior observation chamber 2 is provided with a first air inlet structure on one side relative to the first chamber 1, and the first odor bottle 8 is connected to the first air inlet structure; and the second insect behavior observation chamber 3 is provided with a second air inlet structure on one side relative to the first chamber 1, and the second odor bottle 13 is connected to the second air inlet structure.

[0067] It can be understood that the first air inlet structure is arranged on one side of the first insect behavior observation chamber 2 for introducing gas or odor substances from the first odor bottle 8, and is arranged on one side of the second insect behavior observation chamber 3 for introducing gas or odor substances from the second odor bottle 13.

[0068] At the beginning of the experiment, the first odor bottle 8 and the second odor bottle 13 release gas or odor substances into the first insect behavior observation chamber 2 and the second insect behavior observation chamber 3 respectively. These odor substances enter the respective insect behavior observation chambers through the air inlet structure and diffuse in the chambers to form a stable odor environment. After the insects are introduced into the first chamber 1, they can choose to enter the first insect behavior observation chamber 2 or the second insect behavior observation chamber 3 according to their preference or reaction to the two different odor sources.

[0069] It should be noted that in the optional embodiment of the present application, the air inlet structure is an air inlet. However, it should be understood that the air inlet structure can also be any other suitable air inlet device that can communicate the first insect behavior observation chamber 2 and the second insect behavior observation chamber 3 with the outside.

[0070] According to one embodiment of the present application, the air ventilation device comprises a first air flow meter 9, a second air flow meter 14 and an air pump 4, the air pump 4 is connected to the first air flow meter 9 and the second air flow meter 14, the first air flow meter 9 is connected to the first odor bottle 8, and the second air flow meter 14 is connected to the second odor bottle 13.

[0071] It can be understood that one end of the first gas flow meter 9 is connected to the output end of the air pump 4, and the other end is connected to the first odor bottle 8, which ensures that the gas flow can accurately flow to the first insect behavior observation chamber 2. One end of the second gas flow meter 14 is also connected to the output end of the air pump 4, and the other end is connected to the second odor bottle 13, which ensures that the gas flow can accurately flow to the second insect behavior observation chamber 3.

[0072] After the air pump 4 is started, a stable gas flow is generated and flows through the pipeline to the first gas flow meter 9 and the second gas flow meter 14, respectively. The two gas flow meters accurately control the gas flow size to the respective odor bottles according to the preset flow value. The odor material is released from the odor bottle into the corresponding insect behavior observation chamber under the carrying of the gas flow, forming a stable odor environment. The pipeline connecting the first gas flow meter 9, the second gas flow meter 14, and the air pump 4 can be a rubber tube.

[0073] In one embodiment, the air ventilation device further comprises an activated carbon column, which is arranged on the gas flow path of the first odor bottle 8, the second odor bottle 13, the first gas flow meter 9, the second gas flow meter 14, and the air pump 4.

[0074] In one embodiment, the first insect behavior observation chamber 2 and the second insect behavior observation chamber 3 can also be connected to the atmospheric sampler. By controlling the air blowing rate of the atmospheric sampler, the gas flow rate in the first chamber 1, the first insect behavior observation chamber 2, and the second insect behavior observation chamber 3 can be controlled.

[0075] In one embodiment, as shown in Figure 1 The air inlet device atmospheric sampler is connected to the side wall of the first insect behavior observation chamber 2 and the second insect behavior observation chamber 3. In use, the atmospheric sampler is opened to make the gas pass through the gas insect behavior observation chamber, and the odor emitted by the odor source in the insect behavior observation chamber is evenly blown to the first chamber 1. Then, the test insect in the first chamber 1 makes a behavioral response according to the preference for the odor, whether to enter the observation chamber or stay in the first chamber 1.

[0076] According to one embodiment of the present application, the first insect behavior observation chamber 2 and the second insect behavior observation chamber 3 are located on opposite sides of the first chamber 1.

[0077] It can be understood that the first insect behavior observation chamber 2 and the second insect behavior observation chamber 3 are arranged on the left and right sides of the first chamber 1 respectively, forming a symmetrical structure. Since the two observation chambers are located on the opposite sides of the chamber, there is a certain spatial distance between them, which helps to reduce the cross interference between the odors and ensure that the insects can receive clear and independent odor signals during the test. After the insects are placed in the first chamber 1, they can choose to move to the left (first insect behavior observation chamber 2) or right (second insect behavior observation chamber 3) according to their preference or reaction to the two different odors.

[0078] According to an embodiment of the present application, at least one side wall of the first chamber 1 is provided with a plurality of air permeable holes communicating with the outside. It can be understood that the air permeable holes can ensure the air circulation in the first chamber 1, providing a more natural and comfortable environment for the insects, and also helping the transmission of odor substances between the first chamber 1 and the insect behavior observation chambers.

[0079] According to an embodiment of the present application, the device body is a transparent acrylic device body. It can be understood that due to the high transparency of acrylic material, researchers can clearly observe the behavior changes of insects in the device, including their reactions and selection behaviors to different odors.

[0080] In use, the operator can directly observe the conditions in the first chamber 1, the first insect behavior observation chamber 2 and the second insect behavior observation chamber 3 through the acrylic plate, which is convenient for timely observation and recording. And the use of acrylic plate to make the first chamber 1, the first odor source release chamber 2 and the second insect behavior observation chamber 3 can ensure that the light or other conditions remain consistent.

[0081] In one embodiment, as shown in Figures 2 to 7 The two-way selection device for studying insect olfactory behavior is a cuboid made of acrylic material, with a length of 60 cm, a width of 15 cm and a height of 15 cm. The cuboid is divided into three chambers by a partition, which are a first chamber 1 with a length of 30 cm, a width of 15 cm and a height of 15 cm, and two insect behavior observation chambers with a length of 15 cm, a width of 15 cm and a height of 15 cm.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some technical features; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
