[0047] The observation component 1 is made of transparent resin or PC transparent material, which is easy to observe. Among them, the wall thickness of the shell 11 is 2mm, which can reduce weight and observe the behavior of internal insects, saving costs and eliminating visual blind spots. The transparent resin is processed by 3D printing or lamination, which is used for small batch production. The PC transparent material is processed by mold injection molding, which is suitable for large-scale production. Compared with nylon CNC milling, the two save costs. Among them, the blocking piece 13 is an existing cross-shaped blocking piece 13, and the cross-shaped blocking piece 13 has a through hole, which is smaller than the size of the insect.

[0048] The connecting arm 12 is threadedly connected to the threaded hole, which is convenient for disassembling the connecting arm 12. The threaded hole has a diameter of 80 mm, which is large enough for the experimenter to put his hand in, so as to catch insects and clean and restore the device after the experiment. Figures 1 to 5 As shown, four threaded holes are provided in this embodiment, so four connecting arms 12 and four attractant bottles 2 are provided correspondingly. The four connecting arms 12 are evenly arranged on the sides of the shell 11, and different attractants can be placed in the attractant bottles 2 for experiments.

[0049] The technical solution of the present application circulates air through the air extraction component 3, thereby diffusing the smell of the attractant core in the attractant bottle 2 into the housing 11, so that the insects in the housing 11 can crawl to the attractant core they like, and the direction of the insects can be observed through the observation component 1. In addition, a blocking sheet 13 is provided at the air outlet 112 to prevent the insects in the housing 11 from escaping from the air extraction pipe 32 under the action of the suction pump, thereby ensuring the smooth progress of the experiment.

[0050] According to some embodiments of the present application, optionally, Figure 4 and Figure 5As shown, the observation assembly 1 also includes a connecting air nozzle 14 , and one end of the attractant bottle 2 is connected to the other end of the connecting arm 12 via the connecting air nozzle 14 .

[0051] In this way, the connecting gas nozzle 14 is provided to facilitate the connection between the connecting arm 12 and the lure bottle 2. Optionally, the connecting gas nozzle 14 is detachably connected to the connecting arm 12 and the lure bottle 2, that is, one end of the connecting gas nozzle 14 is threadedly connected to the other end of the connecting arm 12, and the other end of the connecting gas nozzle 14 is just the same size as one end of the lure bottle 2, so that one end of the lure bottle 2 can be inserted, thereby facilitating disassembly and assembly.

[0052] According to some embodiments of the present application, optionally, Figure 1 As shown, the air extraction assembly 3 also includes an air inlet pipe 33 and a gas washing bottle 34 corresponding to the number of the attracting bottles 2. The other end of the attracting bottle 2 is connected to the gas washing bottle 34 through the air inlet pipe 33. The gas washing bottle 34 is used to purify the air.

[0053] In this way, by arranging the air washing bottle 34 to purify the air, the air entering the housing 11 will not have peculiar smell, thereby preventing interference with the experiment. In this embodiment, four air inlet pipes 33 and four air washing bottles 34 are arranged.

[0054] According to some embodiments of the present application, optionally, Figure 1 As shown, the air extraction assembly 3 also includes flow meters 35 corresponding to the number of the attracting bottles 2. The flow meters 35 are connected to the gas washing bottles 34. The flow meters 35 are used to measure the air flow rate.

[0055] In this way, the gas flow velocity is measured by the flow meter 35, thereby ensuring that the gas flow velocity of multiple experiments is consistent, making the experimental data more accurate. In this embodiment, four flow meters 35 are provided.

[0056] According to some embodiments of the present application, optionally, Figure 1 As shown, the attractant bottle 2 is a pear-shaped bottle, one end of the pear-shaped bottle with a large diameter is connected to the other end of the connecting arm 12, and the other end of the pear-shaped bottle with a small diameter is connected to the washing bottle 34 through the air inlet pipe 33.

[0057] Thus, the large diameter of the pear-shaped bottle facilitates the entry of insects, while the small diameter of the pear-shaped bottle can prevent the insects from escaping to the air inlet pipe 33 and affecting the experimental data. Optionally, the lure core can be placed near the large diameter of the pear-shaped bottle, which is more conducive to luring insects.

[0058] According to some embodiments of the present application, optionally, Figure 1 , Figure 4 and Figure 7 As shown, the observation assembly 1 also includes a screw cap assembly 4, which includes a connecting screw cap 41, which is threadedly connected to the insect inlet 111, and the connecting screw cap 41 is used to close or open the insect inlet 111.

[0059] The connecting screw cap 41 is a plum blossom screw cap, which can ensure that insects can be put into the housing 11 through the insect inlet 111 before the experiment, and the insect inlet 111 is closed at the beginning of the experiment to prevent the insects from escaping. In some embodiments, a silicone gasket is provided at the bottom of the connecting screw cap 41 to prevent air leakage.

[0060] According to some embodiments of the present application, optionally, Figure 1 , Figure 4 and Figure 7 As shown, the screw cap assembly 4 also includes an upper plate 42 and a lower plate 43, which are sleeved on the threads of the screw cap 41, and the upper plate 42 and the lower plate 43 are threadedly connected. The screw cap 41 is threadedly connected to the insect inlet 111 through the upper plate 42 and the lower plate 43.

[0061] In this way, the upper plate 42 and the lower plate 43 are threadedly connected to enhance the air tightness of the insect inlet 111 and prevent air from flowing out. In addition, the upper plate 42 can be fixed to the housing 11 by glass glue to ensure air tightness. At the same time, the upper plate 42 has an opening, the size of which is consistent with the size of the sauce cup for holding insects. The lower part of the upper plate 42 is threaded, which is used to be threadedly connected with the lower plate 43 and screwed into the connection screw cap 41.

[0062] According to some embodiments of the present application, optionally, the screw cap assembly 4 further includes a gasket, which is disposed below the upper plate 42 and sleeved on the thread connected to the screw cap 41 .

[0063] A gasket is provided below the upper plate 42, and glass glue is applied to the connection between the outer side of the upper plate 42 and the housing 11, and the gasket is provided to further enhance the air tightness of the insect inlet 111. The gasket is made of silica gel.

[0064] According to some embodiments of the present application, optionally, Figure 1 , Figure 2 and Figure 4 As shown, the observation assembly 1 further includes at least two legs 15 , which are mounted on the bottom of the shell 11 and are used to support the shell 11 .

[0065] The support legs 15 are provided to facilitate supporting the housing 11 and provide sufficient space for the exhaust pipe 32 connected to the air outlet 112. Optionally, two or more support leg connection holes 113 are provided at the bottom of the housing 11, and the support legs 15 are threadedly connected to the support leg connection holes 113 for easy disassembly. In this embodiment, four support legs 15 are provided.

[0066] According to some embodiments of the present application, optionally, Figure 2 and Figure 3As shown, the connecting arm 12 is trumpet-shaped, one end of the connecting arm 12 with a large diameter is threadedly connected to the threaded hole, and the other end of the connecting arm 12 with a small diameter is connected to one end of the attractant bottle 2.

[0067] Thus, setting the connecting arm 12 to be trumpet-shaped is convenient for connecting with the attracting bottle 2 and the threaded hole, and it is not easy for insects to escape from the small-diameter hole into the shell 11 after being attracted to the attracting bottle 2.

[0068] The working principle of the insect olfactory attraction experimental device 100 is as follows: first, place the attractant core in four attractant bottles 2, and connect the vacuum pump 31 to the air outlet 112 of the shell 11 through the vacuum pipe 32. Secondly, turn on the vacuum pump 31 to allow the air in the insect olfactory attraction experimental device 100 to circulate and adjust the flow rate (the order of air circulation is flow meter 35-washing bottle 34-attractant bottle 2-connecting air nozzle 14-shell 11-vacuum pump 31). Again, unscrew the screw cap assembly 4 at the insect inlet 111, and put the sauce bottle containing insects (the outlet of the sauce bottle corresponds to the insect inlet 111) upside down. After all the insects in the sauce bottle enter the shell 11, observe the behavior of the insects inside through the transparent shell 11. When the insects enter the connecting arm 12 from the shell 11, it is considered that the attraction is successful, and the number of insects entering is counted. Finally, when the experimental time is reached, stop the experiment and take out the insects inside the device.
