[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] like Figure 1-5 As shown, the utility model provides a device for studying insect selectivity to living tobacco tissue, the device comprising a No. 1 sample area 1, a No. 2 sample area 2, a No. 3 sample area 3, and an insect movement channel 7;

[0033] The No. 1 sample area 1, the No. 2 sample area 2, and the No. 3 sample area 3 are respectively equipped with a No. 1 dish cover 4, a No. 2 dish cover 5, and a No. 3 dish cover 6;

[0034] Sample area No. 1 1, sample area No. 2 2, and sample area No. 3 3 are connected through an insect movement channel 7.

[0035] When studying the interaction between insects and living tobacco plants, each sample area of ​​the utility model can effectively isolate different parts of the tobacco, and different parts of the whole tobacco plant are in their own independent space, which will not affect the insect's selectivity for other parts.

[0036] Specifically, the insect movement channel is a four-way pipe structure, including an inlet pipe and three outlet pipes; one end of the three outlet pipes is respectively connected to sample area 1, sample area 2, and sample area 3, and the other ends are connected to the inlet pipe; an opening for insects to enter is provided at the other end of the inlet pipe.

[0037] Specifically, the No. 1 sample area is a culture dish structure, and a semicircular first notch 11 is provided on the dish wall;

[0038] The No. 2 sample area is a culture dish structure, and a semicircular second notch 21 and a third notch 22 are provided on the dish wall;

[0039] The No. 3 sample area is a culture dish structure, and a semicircular fourth notch 31 is provided on the dish wall;

[0040] The first notch 11 , the second notch 21 , the third notch 22 , and the fourth notch 31 are on the same horizontal line.

[0041] Specifically, the No. 1 dish cover 4 is a culture dish cover structure, a semicircular fifth notch 41 is provided on the dish wall, and a mesh-shaped first air permeable area 42 is provided on the dish top;

[0042] The No. 2 dish cover 5 is a culture dish cover structure, with a sixth semicircular notch 51 and a seventh semicircular notch 52 on the dish wall, and a mesh second air permeable area 53 on the top of the dish;

[0043] The No. 3 dish cover 6 is a culture dish cover structure, a semicircular eighth notch 61 is provided on the dish wall, and a mesh third air permeable area 62 is provided on the dish top;

[0051] Then, place the leaves of the treated tobacco plants in sample area 1 No. 1, place the stems without leaves in sample area 2 No. 2, and place the roots in sample area 3 No. 3, and buckle the corresponding dish covers 4, 5, and 6 respectively. At this time, the gaps in the sample areas are combined with the gaps in the dish covers to seal all parts of the tobacco plants in the sample areas.

[0052] Finally, the insects are put in from the inlet of the insect movement channel, and the insects move along the insect movement channel and finally stay in the sample area. After that, the activities of the insects in the culture dish can be observed with the naked eye, or the activities of the insects can be recorded by a surveillance camera.
