Description

Technical Field

[0001] The present application relates to the technical field of breeding devices, and in particular to a breeding device for Spodoptera frugiperda in corn fields. Background Technique

[0002] Spodoptera frugiperda is a species of the genus Spodoptera in the family Noctuidae of Lepidoptera. It is usually parasitic on plants and is a polyphagous pest with a particularly wide range of host plants. The plants it feeds on the most are corn, cotton, sorghum, and rice, and also include alfalfa, barley, buckwheat, oats, millet, peanuts, ryegrass, sugar beet, sudangrass, soybeans, tobacco, tomatoes, potatoes, onions, wheat, etc. It is a major agricultural pest globally warned by the Food and Agriculture Organization of the United Nations. In order to better conduct scientific and green prevention and control of Spodoptera frugiperda, it is necessary to study the living habits of Spodoptera frugiperda. Therefore, it is necessary to use a breeding device to breed it for convenient observation and research.

[0003] When the existing breeding device is in use, since the older larvae have the habit of cannibalism, it is necessary to breed the larvae separately. Usually, the Spodoptera frugiperda larvae are separately placed into a cylindrical glass breeding dish. After blocking the mouth of the glass bottle with a sponge, a support frame is used to suspend and install multiple breeding dishes, so as to facilitate the staff to breed and observe the larvae in each breeding dish separately.

[0004] However, when using the above method, since the structure of the support frame for suspending and installing multiple breeding dishes is often relatively simple, only multiple insertion holes are opened on the surface to insert and place the breeding dishes, it is very easy for the breeding dishes to slip off and fall during the process of moving and experimenting with the support frame with the breeding dishes inserted, and the placement stability of the breeding dishes is poor. Therefore, the technical personnel in the field have provided a breeding device for Spodoptera frugiperda in corn fields to solve the problems raised in the above background technique.

Detailed implementation manners

[0023] The following further describes the present application in detail Figures 1-4 with reference to the accompanying drawings.

[0024] An embodiment of the present application discloses a feeding device for Spodoptera frugiperda in a corn field. Referring to Figure 3 Figure 4 , a feeding device for Spodoptera frugiperda in a corn field includes a support plate 1 and a plurality of culture dishes 2, wherein the plurality of culture dishes 2 are evenly distributed in the middle of the support plate 1, and further includes

[0025] a plurality of clamping and fixing mechanisms 3, which are evenly distributed on the inner wall of the support plate 1 for clamping and fixing the plurality of culture dishes 2;

[0026] a temperature control mechanism 6, which is located at the bottom of the support plate 1 for adjusting and controlling the feeding temperature;

[0027] The clamping and fixing mechanism 3 includes two arc-shaped clamping plates 301 and a control component 5, and one ends of the two arc-shaped clamping plates 301 are installed on the inner wall of the support plate 1 through the control component 5;

[0028] The control component 5 includes two telescopic sliding grooves 501, two springs 502, two telescopic sliding rods 503, two limiting sliding grooves 504 and two control pull rods 505. The two telescopic sliding grooves 501 are symmetrically formed on the inner wall of the support plate 1. One ends of the two springs 502 are respectively fixedly connected to one ends of the two telescopic sliding grooves 501. The two telescopic sliding rods 503 are respectively slidably connected to the side walls of the two telescopic sliding grooves 501, and one ends of the two telescopic sliding rods 503 are respectively fixedly connected to the other ends of the two springs 502. One ends of the two arc-shaped clamping plates 301 are respectively fixedly connected to the other ends of the two telescopic sliding rods 503. The two limiting sliding grooves 504 are respectively formed at the tops of the two telescopic sliding grooves 501. The two control pull rods 505 are fixedly connected to the tops of the two telescopic sliding rods 503 through sliding through the two limiting sliding grooves 504 respectively;

[0029] The clamping and fixing mechanism 3 further includes two protective soft pads 4. The two protective soft pads 4 are respectively fixedly connected to the other ends of the two arc-shaped clamping plates 301. Specifically, they can be connected by bolts or glued. There is no specific limitation here. In this embodiment, the two protective soft pads 4 are made of rubber;

[0030] The support plate 1 can be divided into upper and lower parts (not shown in the figure), and can be connected together by screws or bolts. An activity cavity for the telescopic sliding rod 503 is formed by enclosing between the upper and lower parts. The cavity plays a certain guiding role. As Figure 3 shown, it can ensure the stability of the movement of the telescopic sliding rod 503.

[0031] In this embodiment, first, the Spodoptera frugiperda larvae are respectively placed into a number of set culture dishes 2. The culture dish 2 is a product sold in the existing market, and no specific explanation is made for its specific structure here. Then, by sliding the set control lever 505, it slides and moves in the provided limit chute 504. By the sliding movement of the control lever 505, the telescopic slide bar 503 connected thereto is driven to slide and retract into the provided telescopic chute 501 under force. By the sliding contraction of the telescopic slide bar 503, the arc-shaped clamping plate 301 connected thereto is driven to move and open under force. At this time, the culture dish 2 is inserted into the jack opened in the middle of the support plate 1. Then, the set control lever 505 is released, and the reaction force provided by the set spring 502 causes the telescopic slide bar 503 to rebound and slide out under force. By the rebound sliding out of the telescopic slide bar 503, the arc-shaped clamping plate 301 is driven to move and close. By the movement and closing of the arc-shaped clamping plate 301, the culture dish 2 is clamped and fixed. At the same time, the provided protective soft pad 4 made of rubber provides elastic contact protection for the clamping part of the arc-shaped clamping plate 301 and the culture dish 2, and effectively increases the friction force of the contact surface to prevent slipping and ensure stability. Similarly, when it is necessary to take out the culture dish 2, by sliding the set control lever 505, the arc-shaped clamping plate 301 is driven to move and open, and the clamping of the culture dish 2 is released. At this time, the culture dish 2 can be taken out by pulling it out from the jack opened at the top of the support plate 1. In this way, it is convenient to firmly clamp and fix the inserted culture dish 2, avoiding the situation that the culture dish 2 is easily slipped and dropped during the movement process, and effectively improving the placement stability effect of the culture dish 2.

[0032] Further, the temperature control mechanism 6 includes a return-shaped plate 601, a base 602, and a measurement and control component 7. The top of the return-shaped plate 601 is fixedly connected to the bottom of the support plate 1. The top of the base 602 is fixedly connected to the bottom of the return-shaped plate 601, and the return-shaped plate 601 is made of transparent glass material. The measurement and control component 7 is installed on the top of the base 602;

[0033] The measurement and control component 7 includes a console 701, a display screen 702, two fixing frames 703, and two temperature sensors 704. The bottom of the console 701 is fixedly connected to the top of the base 602. The display screen 702 is installed at the front end of the console 701. The side walls of the two temperature sensors 704 are fixedly connected to the inner wall of the return-shaped plate 601 through the two fixing frames 703;

[0034] The temperature control mechanism 6 further includes a heating wire 8, and the heating wire 8 is fixedly connected to the top of the base 602;

[0035] After firmly clamping and fixing the culture dish 2 on the basis of the above embodiments, the culture dish 2 can be enclosed inside by the set square plate 601 and the base 602. While enclosing the culture dish 2 by the square plate 601 made of transparent glass, it is convenient for the staff to check the feeding situation of the internal culture dish 2. At the same time, the temperature sensor 704 supported and fixed by the fixing frame 703 is set to detect and sense the temperature of the enclosed environment in real time, and the set display screen 702 is used to display the detected data. When the environmental temperature inside the square plate 601 is too low, at this time, the set electric heating wire 8 is controlled to be energized by the set console 701. The specific principle of the electric heating wire 8 being energized and heated is the prior art, so it will not be explained in detail here. By energizing the electric heating wire 8, heat is generated to heat up the environment enclosed by the square plate 601, and by heating up, the feeding temperature of the culture dish 2 meets the feeding conditions of the Spodoptera frugiperda larvae, thereby realizing the detection, regulation and control of the feeding environment temperature, and effectively improving the feeding survival rate of the Spodoptera frugiperda larvae.

[0036] The implementation principle of a feeding device for Spodoptera frugiperda in corn in the embodiments of the present application is as follows: When in use, first, the Spodoptera frugiperda larvae are respectively loaded into a plurality of culture dishes 2. Then, by sliding the control rod 505, it slides in the opened limit chute 504. By sliding the control rod 505, the telescopic slide rod 503 connected thereto is forced to slide and retract into the opened telescopic chute 501. By the sliding contraction of the telescopic slide rod 503, the arc-shaped clamping plate 301 connected thereto is forced to move and open. At this time, the culture dish 2 is inserted into the insertion hole opened in the middle of the support plate 1. Then, the control rod 505 is released and the telescopic slide rod 503 is forced to rebound and slide out by the reaction force provided by the spring 502. By the rebound sliding out of the telescopic slide rod 503, the arc-shaped clamping plate 301 is forced to move and close. By the movement and closing of the arc-shaped clamping plate 301, the culture dish 2 is clamped and fixed. At the same time, the protective soft pad 4 made of rubber provides elastic contact protection for the clamping part between the arc-shaped clamping plate 301 and the culture dish 2 and effectively increases the friction force of the contact surface for anti-slip and stability. Similarly, when the culture dish 2 needs to be taken out, by sliding the control rod 505 to drive the arc-shaped clamping plate 301 to move and open, the clamping of the culture dish 2 is released. At this time, the culture dish 2 can be taken out by pulling it out from the insertion hole opened at the top of the support plate 1. In this way, the purpose of effectively and conveniently clamping and fixing the inserted culture dish 2 can be achieved, avoiding the situation that the culture dish 2 is easily slipped and dropped during the movement process, and effectively improving the placement stability of the culture dish 2. Secondly, the culture dish 2 can be enclosed inside by the loop-shaped plate 601 and the base 602. The loop-shaped plate 601 made of transparent glass encloses the culture dish 2 and is convenient for the staff to check the feeding situation of the internal culture dish 2. At the same time, the temperature sensor 704 supported and fixed by the fixing frame 703 senses the temperature of the enclosed environment in real time, and the detected data is displayed on the display screen 702. When the environmental temperature inside the loop-shaped plate 601 is too low, at this time, the control console 701 is used to control the heating wire 8 to be energized. By the energization of the heating wire 8, heat is generated to heat and raise the temperature of the environment enclosed by the loop-shaped plate 601. By heating and raising the temperature, the feeding temperature of the culture dish 2 meets the feeding conditions of the Spodoptera frugiperda larvae, and further achieves the purpose of effectively and conveniently detecting and regulating the temperature of the feeding environment, thereby effectively improving the feeding survival rate of the Spodoptera frugiperda larvae.

[0037] The above are all the preferred embodiments of the present application. Without limiting the protection scope of the present application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
