The mounting plate 12 can rotate above the bottom plate 11 through the bearing 111 with the bearing 111 as the rotation point.

[0038] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 A feeding device 2 is arranged above the mounting plate 12. The feeding device 2 is made of transparent material. The feeding device 2 is a regular heptagonal prism with a cylindrical cavity in the center, which is composed of 7 feeding boxes 21. A slider 213 is provided at the bottom of each feeding box 21, and a slide groove 112 matching the size of the slider 213 is opened on the upper surface of the mounting plate 12, and the position of each slide groove 112 corresponds to the installation position of each slider 213. Each feeding box 21 is fixed on the mounting plate 12 by inserting the slider 213 into the slide groove 112, so that the feeding device 2 formed by splicing 7 feeding boxes 21 is fixed on the mounting plate 12.

[0039] Reference Figure 5 The interior of the feeding box 21 is empty, a vertical notch 211 is provided on the arc-shaped side wall of the feeding box 21, and a second groove 212 is provided inside the arc-shaped side wall of the feeding box 21 near the notch 211, the second groove 212 is communicated with the outside, and a substance for attracting the larvae of the striped stem borer is placed in the second groove 212, so that the larvae of the striped stem borer can be attracted to enter the interior of the feeding box 21 through the notch 211; a pupation board 22 is provided inside the feeding box 21, and the pupation board 22 is made of a transparent material, specifically as shown in FIG. Figure 6 As shown, the pupation plate 22 is a honeycomb-shaped porous plate, and the porous plate is composed of hollow columnar holes arranged in an array.

[0040] Reference Figure 7 and Figure 8 A delivery device 3 is provided at the center of the feeding device 2, and the delivery device 3 consists of two parts: a screening tube 31 and a delivery funnel 32, wherein the delivery funnel 32 is detachably installed above the screening tube 31, and the inner surfaces of the screening tube 31 and the delivery funnel 32 are rough, and the larvae of the striped stem borer can stay on the windproof inner surfaces of the screening tube 31 and the delivery funnel 32.

[0041] Specifically, the screening tube 31 is a cylindrical tube body, and the size of the screening tube 31 is the same as the size of the central cylindrical cavity of the feeding device 2. When the screening tube 31 is installed in the feeding device 2, the outer wall of the screening tube 31 is in close contact with the arc-shaped outer wall of the feeding box 21; the tube wall of the screening tube 31 is provided with a circular first inlet 311, a second inlet 312, a third inlet 313, a fourth inlet 314, a fifth inlet 315, a sixth inlet 316 and a seventh inlet 317 from bottom to top, and the diameters of the first inlet 311, the second inlet 312, the third inlet 313, the fourth inlet 314, the fifth inlet 315, the sixth inlet 316 and the seventh inlet 317 are 1.61 mm, 1.47 mm, 1.35 mm, 1.05 mm, 0.71 mm, 0.47 mm and 0.31 mm respectively. After the selection tube 31 is installed in the breeding device 2, the first inlet 311, the second inlet 312, the third inlet 313, the fourth inlet 314, the fifth inlet 315, the sixth inlet 316 and the seventh inlet 317 are respectively opposite to the gaps of the seven breeding boxes 21, and the larvae of the striped stem borer can enter the seven breeding boxes 21 through the first inlet 311, the second inlet 312, the third inlet 313, the fourth inlet 314, the fifth inlet 315, the sixth inlet 316 and the seventh inlet 317 respectively; six partition plates 318 are evenly distributed in the screening tube 31, and the six partition plates 318 divide the interior of the screening tube 31 into seven spaces, and two adjacent inlets are separated by the partition plates 318, and a circular through hole 3181 is opened on the partition plate 318, and the diameter of the through hole 3181 is greater than or equal to 1.61 mm The through hole 3181 can make the seven spaces interconnected. When in use, the larvae of the striped stem borer are put into the putting funnel 32. Because the second groove 212 of each feeding box 21 is filled with a substance that attracts the larvae of the striped stem borer in advance, the larvae of the striped stem borer will crawl into the screening tube 31. First, the larvae of the striped stem borer enter the space where the seventh inlet 317 is located. Since the diameter of the seventh inlet 317 can only allow larvae with a head width equal to or less than 0.31 mm to enter, larvae with a head width greater than 0.31 mm can only pass through the through hole. 3181 continues to crawl downwards into the space where the sixth entrance 316 is located. Since the diameter of the sixth entrance 316 can only allow larvae with a head width less than or equal to 0.47 mm to enter, and most of the larvae with a head width less than or equal to 0.31 mm have entered the breeding box 21 through the seventh entrance 317, the head width of the vast majority of the Chilo suppressalis larvae that enter the breeding box 21 through the sixth entrance 316 is between 0.31 mm and 0.47, and so on, until all seven breeding boxes 21 have Chilo suppressalis larvae entered.

[0042] refer to Figure 6In order to facilitate the observation of the pupation and emergence of the Chilo suppressalis larvae, the feeding device 2 and the pupation plate 22 are both made of transparent materials. In order to provide a dark environment for the Chilo suppressalis larvae, a shading plate 23 is also provided on the outside of the feeding device 2. The shading plate 23 is detachable and can be removed when observing the pupation and emergence of the Chilo suppressalis larvae.

[0043] Reference Figure 1 and Figure 2 In order to protect the feeding device 2, a protective cover 4 is provided on the outside of the feeding device 2. The protective cover 4 is fixed to the mounting plate 12 through a first annular groove 121 provided on the upper surface of the mounting plate 12. A protective cover 41 is detachably fastened on the top of the protective cover 4.

[0044] A device for observing the pupation and emergence behavior of a rice stem borer. When in use, firstly, a pupation plate 22 is placed inside a feeding box 21, and then a substance that can attract the larvae of the rice stem borer is placed in a second groove 212. Then, the feeding box 21 is installed on a mounting plate 12, and then a screening tube 31 is inserted into the middle of the feeding device 2, and at the same time, each inlet on the screening tube 31 is ensured to correspond to a notch 211 of the feeding box 21. Then, a delivery funnel 32 is installed above the screening tube 31, and the larvae of the rice stem borer are delivered into the screening tube 31, and then the larvae are delivered to the inside of the screening tube 31. The larvae of the striped stem borer are divided into seven parts according to the width of their heads through the inlets of different sizes, so that the width of the heads of the striped stem borer larvae in each rearing box 21 is basically the same, and then the shading plate 23 is sleeved on the outside of the rearing device 2, and then the protective cover 4 of the protective cover 41 is used to buckle the rearing device 2 inside the protective cover 4 for protection. If it is necessary to observe the pupation and eclosion behavior of the striped stem borer, it is only necessary to open the protective cover 41 and remove the shading plate 23, and if you want to observe the situation inside each rearing box 21, you only need to rotate the mounting plate 12.

[0045] By means of the rice stem borer pupation and emergence behavior observation device proposed by the utility model, the stem borer larvae can be divided into seven parts according to the width of the head shell, and each portion of the stem borer larvae is raised separately, and the transparent raising device 2 and the pupation plate 22 can better observe the pupation and emergence behavior of the stem borer, and the rotatable mounting plate 12 can reduce the labor of the observer, so that the observer can better observe the stem borer.

[0046] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
