Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a feeding device for the entire stage of Asian corn borer. Background Technology

[0002] In the field of agricultural pest research, the Asian corn borer is a major pest of crops such as corn. Studying its biological characteristics is crucial for developing effective control strategies, and laboratory rearing is a fundamental method for in-depth research into its growth and development patterns. Currently, existing rearing equipment for silk-spinning insects such as the Asian corn borer in laboratory artificial climate chambers has many shortcomings.

[0003] During the larval stage, conventional rearing boxes often have poor spatial layouts or ventilation, failing to meet the Asian corn borer larvae's needs for activity space and air circulation. This negatively impacts larval growth and development, potentially leading to stunted growth or disease transmission. When the larvae reach their fifth instar and are about to pupate, existing rearing devices lack a suitable pupation environment design, failing to provide a safe, narrow space conducive to silken encirclement during pupation. This results in a low pupation success rate, hindering subsequent research. Furthermore, during the Asian corn borer's emergence stage, existing devices do not provide sufficient space for wing development after hatching, often leading to wing deformities or inability to unfold properly. This degrades the quality of experimental samples, affecting the accuracy and reliability of research results. Therefore, this invention proposes a full-stage rearing device for the Asian corn borer. Utility Model Content

[0004] The purpose of this invention is to address the problems in the existing rearing devices in the background art, such as insufficient space and ventilation during the larval stage, incompatible environment during the pupal stage, and lack of wing-spreading space during the emergence stage, which lead to poor larval development, low pupation success rate, and reduced experimental sample quality, thus affecting the accuracy and reliability of research. The invention proposes a full-stage rearing device for the Asian corn borer.

[0035] Example

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, this utility model proposes a full-stage feeding device for Asian corn borers, comprising a box 1 with openings at the top and bottom. A top cover 2 is installed on the top of the box 1, and a positioning frame 22 is fixedly connected to the bottom of the top cover 2. The outer side of the positioning frame 22 is fitted against the inner wall of the box 1. The positioning frame 22 guides the top cover 2 during installation, ensuring that the top cover 2 will not shake after installation. Multiple sets of grooved plates 3 are provided below the top cover 2. Each grooved plate 3 includes a side plate 31, and multiple sets of partition plates 32 are fixedly connected to the side of the side plate 31 in an equidistant array. The gaps between adjacent sets of side plates 31 create a safe, narrow environment that facilitates silk-spraying and encirclement, conforming to the habits of the Asian corn borer.

[0037] Furthermore, the aforementioned feeding device includes a mesh plate 4 installed at the bottom of the box 1. The mesh plate 4 is designed to allow insect excrement to fall downwards while preventing larvae from passing through. A collection tray 5 is located below the mesh plate 4 to catch the insect excrement for centralized processing. A support base 51 is slidably connected to the outside of the collection tray 5. The support base 51 has an opening at the top and one side and is fixedly connected to the bottom of the box 1 to facilitate the sliding removal of the collection tray 5. A handle 52 is installed on one side of the collection tray 5 to facilitate pulling the collection tray 5.

[0038] Furthermore, the aforementioned feeding device also includes multiple sets of mesh screens 6 installed on the top of the top cover 2. The mesh screens 6 are designed to facilitate ventilation and allow light to enter the box body 1. A pressure plate 61 is installed above one end of the mesh screen 6, and at least two sets of screws 62 are threaded through the pressure plate 61. The screws 62 are threadedly connected to the box body 1, fixing the pressure plate 61 to the top of the box body 1. At the same time, the pressure plate 61 presses down on one end of the mesh screen 6, fixing the position of one end of the mesh screen 6. The connection method using screws 62 also facilitates the disassembly, cleaning, or replacement of the mesh screen 6. A locking post 63 is fixedly connected to the end of the mesh 6 away from the pressure plate 61. Two sets of elastic pieces 64 are provided at both ends of the locking post 63. The two sets of elastic pieces 64 are symmetrically arranged on both sides of the locking post 63. A protrusion 65 is fixedly connected to the opposite side of the two sets of elastic pieces 64. The other end of the mesh 6 is positioned by the elastic pieces 64 and the protrusions 65. At the same time, the locking post 63 can be easily removed from between the two sets of elastic pieces 64. After removal, the mesh 6 can be flipped over to expose the through hole 21 below, which makes it easy to add food to the box body 1.

[0039] The top cover 2 has through holes 21 at positions corresponding to the mesh 6, facilitating the entry of light and air, and also allowing for the placement of food. An LED tube 7 is installed above the mesh 6 to provide photoperiod for feeding. A mounting bracket 71 is installed above the LED tube 7, with four sets of positioning rods 72 fixedly connected to the bottom of the bracket 71. Positioning sleeves 73 are slidably connected to each of the four positioning rods 72, and all four positioning sleeves 73 are fixedly connected to the box body 1. The positioning rods 72 and positioning sleeves 73 determine the position of the mounting bracket 71, ensuring accurate installation of the LED tube 7. A positioning ring 74 is fixedly connected to the outer ring of the positioning rods 72 above the positioning sleeves 73, limiting the installation height of the mounting bracket 71.

[0040] For details, please refer to Figures 3 to 5 The aforementioned feeding device also includes a locking mechanism 8 disposed above multiple sets of grooved plates 3. The locking mechanism 8 is used to lock the multiple sets of grooved plates 3. The locking mechanism 8 includes multiple sets of connecting plates 81, which are respectively fixedly connected to the top of the multiple sets of grooved plates 3. The connecting plates 81 and the grooved plates 3 move synchronously. Two sets of connecting blocks 82 are fixedly connected to the top of the connecting plates 81. An inclined block 83 is fixedly connected to the side of the two sets of connecting plates 81 that is far apart from each other. Both the connecting blocks 82 and the inclined blocks 83 can penetrate the top cover 2. A locking block 84 is also provided on the side of the two sets of connecting blocks 82 that is far apart from each other. When the connecting plates 81 are installed, the connecting blocks 82 drive the inclined blocks 83 to press the locking block 84 and move it. After the inclined blocks 83 pass the position of the locking block 84, the locking block 84 locks the inclined blocks 83, thereby limiting the position of the connecting plates 81, so that the connecting plates 81 are locked after being installed to the bottom of the top cover 2. Multiple sets of locking blocks 84 on the same side are fixedly connected to a synchronous plate 85. When the synchronous plate 85 moves, it drives the multiple sets of locking blocks 84 to move synchronously. Multiple sets of moving rods 86 are fixedly connected to the side of the synchronous plate 85 away from the connecting block 82. The moving rods 86 move synchronously with the synchronous plate 85. Fixed plates 87 are slidably connected to the multiple sets of moving rods 86. The multiple sets of fixed plates 87 are all fixedly connected to the top of the top cover 2. The position of the fixed plates 87 is fixed, and together with the limiting effect of the moving rods 86, it makes the movement of the synchronous plate 85 smooth. A spring 88 is sleeved on the outer ring of the moving rod 86. The spring 88 is set between the synchronous plate 85 and the fixed plate 87. Through the elastic force of the spring 88, when the locking block 84 is pressed and moved by the inclined block 83, it drives the synchronous plate 85 to press the spring 88. The accumulated elastic force of the spring 88 makes it easy to drive the locking block 84 to reset. A limit plate 89 is fixedly connected to the end of the moving rod 86 away from the synchronous plate 85. The limit plate 89 prevents the moving rod 86 from disengaging from the fixed plate 87.

[0041] like Figure 1 As shown, the above-mentioned breeding device also includes a temperature and humidity controller 9 installed on the side of the box 1. The temperature and humidity controller 9 is used to provide controllable temperature and humidity for insect breeding. It is existing technology and will not be described in detail here.

[0042] In this embodiment, when installing the grooved plate 3, the connecting plate 81 drives the connecting block 82 and the inclined block 83 through the top cover 2. The inclined block 83 presses against the locking block 84, causing the synchronous plate 85 to compress the spring 88. After the inclined block 83 passes through, the spring 88 pushes the locking block 84 back to its original position, locking the inclined block 83 and thus firmly fixing the grooved plate 3, ensuring a stable pupation environment. At this time, the mesh 6 can easily expose the through hole 21 through the cooperation of the locking post 63, the elastic piece 64, and the protrusion 65, allowing the keepers to add food to the box 1 through the through hole 21.

[0043] During the larval rearing stage, the ample space inside the box 1 provides a place for the larvae to move around, and the mesh 6 on the top of the lid 2 ensures air circulation, meeting the larvae's need for a breathable environment. The mesh plate 4 prevents the larvae from falling and allows their excrement to fall into the collection tray 5 below. The rearer can easily pull out the collection tray 5 using the handle 52 to clean the excrement and maintain a clean rearing environment.

[0044] When the larvae develop to the fifth instar and are about to pupate, the grooved plate 3 plays a crucial role. The narrow gap formed by the side plate 31 and the partition plate 32 creates a safe environment for the larvae to spin silk and enclose themselves in a pupal state, which is in line with their pupal habits. During the emergence stage of the Asian corn borer, the space reserved between the two sets of grooved plates 3 inside the box 1 is sufficient for the adult to emerge from the pupal case and complete the wing-spreading action.

[0045] The LED light tube 7 on top of the top cover 2 is precisely installed with the assistance of the positioning rod 72, positioning sleeve 73, and positioning ring 74, providing a stable light cycle for the feeding process and meeting the light requirements of the Asian corn borer. In addition, the temperature and humidity controller 9 on the side of the box 1 continuously monitors and adjusts the ambient temperature and humidity to ensure that the entire feeding process is always in an environment suitable for the growth and development of the Asian corn borer.

[0046] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
