[0002] At present, major pests in the world include many herbivorous insects, such as diamondback moth, aphids, whiteflies, locusts, etc., which are one of the main pests of grain crops, vegetables, fruit trees and ornamental plants. In order to prevent and control these herbivorous pests, increase the yield of economic crops, and analyze their damage mechanism, plants are usually cultured in the laboratory to simulate insect damage to carry out insect inoculation and insect collection observation, so as to compare the differences in biological indicators between herbivorous insects and plants and study the damage mechanism of herbivorous pests. At present, the method of in vitro feeding of some branches and leaves of plants or branch and leaf damage treatment is generally adopted. The former in vitro culture will shorten the survival time of the plant, change various physiological functions, and cannot evaluate the impact on the overall plant; the latter simulates different levels of damage. In this process, herbivorous insects are small in size but have long feeding time and large activity range, so it is often difficult to find the insect collection process, which makes the statistical error of experimental data large.

[0029] The following will further elaborate on the present utility model in conjunction with the attached Figure 1-6 drawings.
[0030] Embodiment 1
[0031] Referring to Figure 1 , Figure 4 , this embodiment discloses a single-plant type insect receiving experiment device for phytophagous insects. An insect receiving experiment device for phytophagous insects includes a housing, a shield 4, and a plurality of support rods 3. The housing includes a first screen 1 and a second screen 2. The first screen 1 is wrapped around the outside of the top of the plant 7 for receiving phytophagous insects; the second screen 2 is connected to the outside of the bottom end of the first screen 1, and the second screen 2 is arranged in the middle of the plant 7 and is hollow inside; the shield 4 is detachably connected by two halves and is arranged on the upper surface of the plant basin body 5. The upper surface of the shield 4 is fixedly connected to the bottom end of the housing, and a through hole for the plant stem 8 to pass through is opened in the middle of the shield 4; a plurality of support rods 3 are fixedly connected to the periphery of the housing, and the bottom of the support rods 3 is fixedly connected to the shield 4. The support rods 3 and the housing can be bonded by glue or fixed by sewing with a needle and thread; the support rods 3 and the shield 4 are bonded by glue.
[0032] The first screen 1 and the second screen 2 can provide sufficient activity space for the host plant 7 and insects, and the overall device occupies a small space, which is convenient for management. At the same time, the first screen 1 and the second screen 2 can ensure air circulation and ensure the normal growth and development of the plant 7. The setting of the shield 4 can prevent insects from escaping into the soil and gnawing on the roots, and can also ensure the insect recovery rate to the greatest extent. Generally, the insect receiving experiment time is one week, and the overall device can protect the plant from mechanical damage.
[0033] Referring to Figure 1 , a zipper 6 is sewn at the connection of the first screen 1 and the second screen 2. When performing the insect receiving and collecting operation, the zipper 6 is opened to an extent that can accommodate both hands and tools to enter, which is convenient for experimental operation. There is no need to remove the housing to avoid insect escape, and the opening range is flexible, reducing damage to the plant 7.
[0034] Referring to Figure 3, the shield 4 includes a first shield 10 and a second shield 12. The two ends of the first shield 10 are fixedly connected with protruding columns 11, and the two ends of the second shield 12 are provided with grooves 13 adapted to be inserted with the protruding columns 11, which is beneficial to place the shield at the plant stem 8 without causing mechanical damage to the plant stem 8.
[0035] Reference Figure 2 , a sponge ring 9 is further arranged between the shield 4 and the plant stem 8. The sponge ring 9 is a pva soft sponge. The sponge ring 9 is composed of two semi-circular rings, with a small diameter of 1 - 2 cm, a large diameter of 3 - 4 cm, and a height of 1 cm. The sponge ring 9 is stuck between the shield 4 and the plant stem 8. Using the soft pva sponge can protect the plant stem 8 from mechanical damage, and the relatively thick sponge ring 9 has an adjustment space to ensure that the gap between the plant stem 8 and the shield 4 is completely shielded and can adapt to the growth of the stem and stems of different thicknesses.
[0036] Reference Figure 1 , the support rod 3 can be telescopic and can adapt to plants of different heights.
[0037] Reference Figure 1 , the materials of the housing, the shield 4 and the support rod 3 are all transparent materials. The transparent materials can ensure that the plants have sufficient sunlight.
[0038] Reference Figure 2 , Figure 4 , the cross-section of the housing is circular, making the influence of the device on each side of the plant the same.
[0039] Embodiment 2
[0040] Reference Figure 1 , Figure 4 , this embodiment discloses a double-plant type insect-catching experiment device for phytophagous insects.
[0041] The difference from the single-plant type device is that a baffle 14 is arranged inside the housing, dividing the housing into two spaces for adapting to the double-plant type plants 7. Through holes are provided at the bottoms of the shields 4 in both spaces for the stems of the double-plant type plants to pass through. The cross-section of the housing is oval, making the influence of the device on each side of the plant the same.
[0042] In the double-plant type device, the baffle 14 can separate the two plants 7, enabling the plants 7 to have independent spaces and facilitating independent experimental operations. The material of the baffle 14 is a transparent material, which can ensure that the plants have sufficient sunlight. The baffle 14 can be a dense wire mesh or a plastic baffle.
[0043] The utility model is convenient to operate, has a low cost, and can well simulate the situation of insects feeding on plants in the natural state. It can provide sufficient activity space for the host plants 7 and insects, and the whole device occupies a small space, which is convenient for management.
[0044] The above are all preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present utility model shall be covered within the protection scope of the present utility model.
