[0002] Citrus psyllids harm the tender branches and leaves of navel oranges. Adults often feed on tender shoots and leaf backs, while nymphs gather on tender shoots and leaves to suck. The damaged tender shoots and buds wither and shrink, and new leaves become twisted and deformed. Nymphs often excrete white flocculent secretions that cover the areas where the insects move. Psyllids can also induce sooty disease, leading to weak tree vigor and reduced yield and fruit quality. Psyllids are also important vectors of Huanglongbing, which is extremely harmful to citrus production.

[0003] In the prior art, a Chinese patent document with publication number CN112430639A proposes a method for determining the pathogenicity of citrus psyllid entomogenous fungi, which solves the problem of raising citrus psyllids in insect cages and then inoculating entomogenous fungi in Murraya aromatica potted plants. Because the volume of the insect cage is too large and the citrus psyllids are too small, it is not easy to observe and count the deaths of citrus psyllids. However, in actual application, the leaves of Murraya aromatica are relatively delicate and easy to rot, and excessive humidity can easily cause diseases in Murraya aromatica. Therefore, the above patent proposes that maintaining the relative humidity in the measuring cup to reach more than 95% will be difficult to ensure the normal survival of Murraya aromatica, and the cultivation of Murraya aromatica requires appropriate It needs suitable humidity and nutrients, and also likes to grow in a relatively ventilated environment. Therefore, it is not easy for the sweet olive in the test cup to survive normally, which leads to the weakening of the sweet olive, affects the palatability of the citrus psyllid, and causes the citrus psyllid to die prematurely due to lack of nutrition, affecting the accuracy of the experimental results. The citrus psyllid that died during the experiment needs to be taken out in time for measurement, but the citrus psyllid that is still alive in the test cup may fly out at this time, affecting the staff to pick up the dead citrus psyllid. Therefore, we disclose a measurement device and method for the pathogenicity of citrus psyllid fungi to meet the needs of the normal survival of the sweet olive in the test cup.

[0041] S2, when the citrus psyllid dies, it will fall to the upper end of the second mesh plate 14, and at this time, the handle 18 relative to the citrus psyllid is operated to drive the second mesh plate 14 to rotate 90 degrees, so that the citrus psyllid slides down the second mesh plate 14 to the upper end of the light-colored absorbent paper 12 under the influence of its own gravity, and then the second mesh plate 14 is rotated to the original position;

[0042] S3. Rotate the corresponding first screen plate 7 to open the measuring cup 1, pick up the citrus psyllids dropped from the upper end of the light-colored absorbent paper 12, so that the measuring cup 1 is more ventilated, and can provide suitable humidity and nutrients for the Murraya osmanthus 13, which is beneficial to the normal survival of the Murraya osmanthus 13 and is not easy to weaken. It is convenient to pick up the citrus psyllids after they die, and the living citrus psyllids will not fly out when picking them up, which is beneficial to the operation of the staff.

[0043] The working principle of the present invention is as follows: when in use, the measuring cup 1 is located in the water storage tray 4 through the supporting legs 3, so that the culture matrix 11 in the measuring cup 1 absorbs the water in the water storage tray 4 through the absorbent cotton 6, so that the culture matrix 11 remains moist and does not cause the root of the Murraya 13 to rot, and the staff can add nutrients to the water storage tray 4 to promote the normal survival of the Murraya 13. Ventilation holes 10 are provided on both sides of the middle of the measuring cup 1, and the upper end of the ventilation hole 10 is rotatably connected to the first mesh plate 7, so that the middle of the measuring cup 1 can realize airflow through the first mesh plate 7, so that the air in the inner cavity of the measuring cup 1 can circulate, thereby increasing the survival rate of the Murraya 13, and when the citrus psyllids die and need to be taken out, they can be The first mesh plate 7 can be opened and taken out directly to avoid the problem of difficulty in taking out the citrus psyllid due to the deep depth of the measuring cup 1 and the small size of the citrus psyllid. The staff can take out the citrus psyllid, which is convenient for operation. After the first mesh plate 7 is closed and naturally droops, it fits with the first baffle plate 8 and the second baffle plate 9 to prevent the citrus psyllid from flying out of the gap between the first mesh plate 7 and the measuring cup 1. A light-colored absorbent paper 12 is laid on the upper end of the culture matrix 11, and the first mesh plate 7 is located on the upper end of the light-colored absorbent paper 12, which is convenient for finding and taking out the citrus psyllid. A plurality of air holes 5 are opened at the bottom end of the measuring cup 1, so that the culture matrix 11 in the inner cavity of the measuring cup 1 has better air permeability, which is conducive to the survival of the sweet olive 13.

[0044] When the handle 18 moves, the limit rod 19 is first pulled to move from the limit groove 20 to the moving groove 21. Then, when the handle 18 is rotated, the connecting plate 16 is driven to move through the limit rod 19, so that the rotating shaft 15 and the second mesh plate 14 are rotated, so that the moving position of the limit rod 19 is limited by the moving groove 21, thereby limiting the moving position of the connecting plate 16, ensuring the stability of the rotating shaft 15 during rotation, so that the position of the second mesh plate 14 before and after rotation is relatively stable and not easy to shake, which is convenient for use. The two second mesh plates 14 are respectively located on both sides of the two osmanthus trees 13, so that the upper and lower ends of the second mesh plates 14 are separated, limiting the activity range of the citrus psyllids, so that when the staff takes the dead citrus psyllids, the surviving citrus psyllids will not fly out, which is convenient for the staff to pick up the dead citrus psyllids.

[0045] After the Osmanthus fragrans 13 passes through the third baffle plate 22 and the fourth baffle plate 23, it can be placed at the bottom of the measuring cup 1, so that the clamp ring 24 can fill the gap between the third baffle plate 22, the fourth baffle plate 23 and the Osmanthus fragrans 13, so as to prevent the citrus psyllids from flying from between the third baffle plate 22 and the fourth baffle plate 23 to the lower end of the second mesh plate 14. After the dead citrus psyllids fall to the fourth baffle plate 23 or the upper end of the third baffle plate 22, they can slide to the upper end of the second mesh plate 14. The clamp ring 24 includes two semicircular rings, the two semicircular rings are rotatably connected, and one semicircular ring is rotatably connected. It is connected to a connecting rod 25, and another semicircular ring is fixedly connected to a limiting block 26. The connecting rod 25 is an L-shaped rod, and the limiting block 26 is movably connected to the connecting rod 25. The lower end of the clamping ring 24 is arc-shaped and fits with the top surface of the fourth baffle 23, so that the clamping ring 24 is easy to fit with the outer wall of the Murraya osmanthus 13, which is convenient to operate, so that the clamping ring 24 and the Murraya osmanthus 13 fit better, preventing citrus psyllids from flying to the lower end of the second mesh plate 14 through the gap between the clamping ring 24 and the Murraya osmanthus 13, so that the second mesh plate 14 can better separate the inner cavity space of the measuring cup 1.
