DETAILED DESCRIPTION

[0025] The utility model is further described below in conjunction with the accompanying drawings:

[0026] In this embodiment, a corn borer resistance monitoring device is proposed. Figure 1 and Figure 2As shown, the side walls and the bottom of the monitoring box 1 are respectively processed with a plurality of through holes to ensure the flow of external air, so that the environment inside the monitoring box 1 is the same as the external environment, and the activity of corn borers is ensured during the experiment. A box cover 2 is arranged on the top of the monitoring box 1. The monitoring box 1 and the box cover 2 are both made of PET material. The light transmittance of PET is 90%. The high transparency is convenient for personnel to monitor the situation of corn borers inside. At the same time, PET has good tensile properties, which facilitates the tighter connection between the box cover 2 and the monitoring box 1. An auxiliary structure 3 is arranged at the bottom of the monitoring box 1. The auxiliary structure 3 is used to put corn husks soaked in insecticides into the interior of the monitoring box 1, and at the same time, it can prevent the corn borers inside the monitoring box 1 from flying out of the monitoring box 1 when the corn husks soaked in insecticides are put into the interior of the monitoring box 1.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the auxiliary structure 3 includes a connecting groove 301, a first step block 302, a second step block 303, a bearing plate 304, an arc block 305 and a connecting block 306. There are two connecting grooves 301, and the connecting grooves 301 on both sides are mirror-imaged on both sides of the monitoring box 1. The first step block 302 is fixedly connected to the connecting groove 301 on one side, and the second step block 303 is fitted with the connecting groove 301 on the other side. The second step block 303 can slide inside the corresponding connecting groove 301;

[0028] The first step block 302 and the second step block 303 are of the same size and shape, the top width of the first step block 302 and the second step block 303 is the same as the distance between the inner and outer annular surfaces of the monitoring box 1, and the bottom width of the first step block 302 and the second step block 303 is half of the distance between the inner and outer annular surfaces of the monitoring box 1. The groove formed between the first step block 302 and the connecting groove 301 supports one side of the bearing plate 304, and the other side of the bearing plate 304 is fixedly connected to the second step block 303, and the second step block 303 can drive the bearing plate 304 to move;

[0029] Both ends of the support plate 304 fit in with the connection groove 301 , and the gap between the upper end surface of the support plate 304 and the connection groove 301 can ensure that the corn husk follows the support plate 304 to move into the interior of the monitoring box 1 .

[0030] The outer ring surface of the second step block 303 is fixedly connected to the arc block 305, and both sides of the inner ring surface of the arc block 305 are in contact with the monitoring box 1, so that the arc block 305 is convenient for personnel to pull the second step block 303. Connecting blocks 306 are respectively provided on both sides of the arc block 305, and the connecting blocks 306 on both sides are fixedly connected to the monitoring box 1. An arc groove 3061 is provided at one end of the connecting block 306 adjacent to the arc block 305, which is used to limit the position of the arc block 305.

[0031] Figure 4 and Figure 5 As shown, cavities 3051 are processed on both sides of the arc block 305, and through holes 3052 are processed on the side ends of the arc block 305, which are connected with the cavity 3051 through 3052. The cavity 3051 and the through holes 3052 are matched with the hemispherical block 3054. The end of the hemispherical block 3054 is fixedly connected to one end of the spring 3053, and the other end of the spring 3053 is fixedly connected to the side wall of the cavity 3051. The hemispherical block 3054 can slide inside the cavity 3051, and the hemispherical block 3054 is matched with the arc groove 3061. When not subjected to external force, the arc block 305 and the hemispherical block 3054 are pressed against each other through the arc groove 3061.

[0032] When a person applies external force to the arc block 305, the arc block 305 moves so that the hemispherical block 3054 is squeezed by the arc groove 3061, so that the hemispherical blocks 3054 on both sides move inward and release the engagement with the arc groove 3061, so that the arc block 305 drives the supporting plate 304 to move through the second step block 303.

[0033] Working principle:

[0034] When monitoring the resistance of corn borers to pesticides, personnel place the adult corn borers inside the monitoring box 1, and then pull the arc block 305. The arc block 305 moves so that the hemispherical block 3054 is squeezed by the arc groove 3061, so that the hemispherical blocks 3054 on both sides move inward and release the engagement with the arc groove 3061, so that the arc block 305 drives the supporting plate 304 to move through the second step block 303, and then the corn husks soaked with the pesticide are placed on the supporting plate 304, and then the supporting plate 304 and the corn husks are moved into the interior of the monitoring box 1. By observing and recording the survival status of the corn borers, and by setting up multiple monitoring boxes 1 to place pesticides of different concentrations, the resistance of the corn borers to pesticides can be judged, thereby monitoring the resistance of the corn borers to pesticides.
