Description

Technical Field

[0001] This application relates to the technical field of pupation of Spodoptera frugiperda in corn, and particularly relates to a pupation device for Spodoptera frugiperda in corn. Background Technique

[0002] Spodoptera frugiperda, also known as fall armyworm and false armyworm, is native to the tropical and subtropical regions of the Americas. It is a major transnational migratory and polyphagous agricultural pest, with characteristics such as a wide host range, a broad suitable growth area, a strong proliferation potential, a strong migratory ability, a fast diffusion speed, and a heavy sudden damage. The larvae of this pest can feed on more than 80 kinds of crops, including corn, rice, sorghum, millet, sugarcane, cotton, and vegetables. The invasion and rapid spread of Spodoptera frugiperda in China have caused huge economic losses to China and will seriously threaten the safety of China's agriculture and food production.

[0003] The establishment of the artificial rearing technology of Spodoptera frugiperda has important economic significance and plays an important role in further conducting prevention and control experiments on Spodoptera frugiperda, formulating a set of scientific and effective prevention and control strategies for Spodoptera frugiperda, and thus achieving the purpose of controlling the harm of the pest population.

[0004] Common Spodoptera frugiperda larva rearing devices usually use finger tubes or modified beverage bottles. This way of breeding can well separate and rear multiple Spodoptera frugiperda larvae, avoiding the mutual killing of the larvae. However, during the pupation process of Spodoptera frugiperda, due to the round shape and inconvenient fixation of the beverage bottle, the surface is arc-shaped, and the entrance and exit are small, which is not convenient for the breeder to observe the pupa closely. Only observation can be carried out outside the bottle, which will affect the observation accuracy of the breeder and reduce the pupation survival rate. Therefore, those skilled in the art have provided a pupation device for Spodoptera frugiperda in corn to solve the problems raised in the above background technique. Utility Model Content

[0005] To solve the problems raised in the above background technique, this application provides a pupation device for Spodoptera frugiperda in corn.

[0006] The pupation device for Spodoptera frugiperda in corn provided by this application adopts the following technical solutions:

[0007] A pupation device for Spodoptera frugiperda in corn, including a base, a lower support frame is arranged above the base, a lower partition is arranged inside the lower support frame, an upper partition is arranged above the lower partition, an upper support frame is arranged around the upper partition, and the upper support frame is located above the lower support frame;

[0008] A cover plate, which is arranged above the upper support frame, and a viewing window plate is rotatably connected inside the cover plate, and the viewing window plate is located above the upper support frame;

[0009] A probe is arranged inside the lower support frame, and a plurality of the probes are arranged. A controller is arranged on one side of the base, and the controller is electrically connected to the plurality of the probes.

[0010] In some embodiments, reinforcing plates are fixedly connected to both sides of the base, and the sides of the two groups of reinforcing plates close to each other are in contact with the outer wall of the cover plate.

[0012] In some embodiments, a plurality of limiting grooves are equidistantly formed inside the lower support frame, a plurality of limiting posts are equidistantly fixedly connected below the upper support frame, and the lower parts of the plurality of limiting posts are respectively inserted into the interiors of the plurality of limiting grooves.

[0013] In some embodiments, a wire groove is opened above the lower partition, the probe is located on one side of the wire groove, one side of the probe is fixedly connected to a fixing tube, one end of the fixing tube is located inside the wire groove and fixedly plugged into the inner wall of the lower partition.

[0014] In some embodiments, a plurality of limit frames are equidistantly arranged above the base, and the upper parts of the limit frames are respectively in contact with the outer walls of the plurality of lower partitions.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] Fix the lower support frame on the top of the base, and then fix the probe on the top of the lower partition inside the lower support frame. Then one end of the probe is connected to the controller through a data cable. The controller mainly detects the temperature and humidity inside the lower partition, which is convenient for personnel to intervene in the pupation process of the fall armyworm intuitively and increase the success rate of pupation. Then the breeder places the upper support frame on the top of the lower support frame. The bottom of the upper partition will be closed with the lower partition. The lower and upper partitions protect the data line of the probe to reduce the risk of bites by the fall armyworm. The interior of the lower and upper partitions is divided into several spaces, where the fall armyworm can be placed. The fall armyworms are raised separately in multiple spaces to avoid cannibalism among each other. When the fall armyworms reach maturity, they will pupate inside the lower and upper partitions. During the pupation process, the staff can lift up the window panel. The window panel is a transparent panel. One side of the window panel is inserted into the inside of the cover panel through a shaft for rotation. The window panel covers the top of the upper support frame. When the window panel is lifted, the keeper can take out the fall armyworm pupae inside the upper support frame, which is convenient for the keeper to observe closely. After the window panel is closed, the upper support frame can be sealed to avoid damage to the fall armyworm pupae by the external environment as much as possible.

[0017] The limiting groove limits the limiting post. When the lower part of the upper support frame fits with the lower support frame, the limiting post will insert into the limiting groove inside the lower support frame, increasing the strength of the connection structure between the upper support frame and the lower support frame, making it difficult for the upper support frame and the lower support frame to deform due to external forces, and increasing the safety during the pupation process of the fall armyworm inside.

Detailed Description of the Embodiment

[0023] The following is a further detailed description of the present application in conjunction with the attached Figures 1-4 drawings.

[0024] An embodiment of the present application discloses a pupation device for the fall armyworm in corn. Referring to Figures 1-4 , a pupation device for the fall armyworm in corn includes a base 1, a cover plate 4 and a probe 8. A lower support frame 2 is arranged above the base 1. A lower partition 21 is arranged inside the lower support frame 2. An upper partition 31 is arranged above the lower partition 21. An upper support frame 3 is arranged around the upper partition 31. The upper support frame 3 is located above the lower support frame 2. The cover plate 4 is arranged above the upper support frame 3. A viewing window plate 5 is rotatably connected inside the cover plate 4. The viewing window plate 5 is located above the upper support frame 3. The probe 8 is arranged inside the lower support frame 2. There are multiple probes 8. A controller 7 is arranged on one side of the base 1. The controller 7 is electrically connected to the multiple probes 8;

[0025] In this way, during the implementation process, when the breeder needs to place the pupated fall armyworm, the breeder first places the base 1 horizontally on the desktop, then fixes the lower support frame 2 above the base 1, and then fixes the probe 8 above the lower partition 21 inside the lower support frame 2, and then one end of the probe 8 is connected to the controller 7 through a data cable. The controller 7 mainly detects the temperature and humidity inside the lower partition 21, which is convenient for personnel to intuitively intervene in the pupation process of the fall armyworm and increase the pupation success rate;

[0026] Then the breeder places the upper support frame 3 on top of the lower support frame 2, and the lower part of the upper partition 31 will be closed with the lower partition 21, and the lower partition 21 and the upper partition 31 protect the data line of the probe 8 to reduce the risk of being bitten by the fall armyworm. The interior of the lower partition 21 and the upper partition 31 is divided into several spaces, and the fall armyworm can be placed in multiple spaces for separate breeding, avoiding cannibalism between the fall armyworm larvae. Then, when the fall armyworm reaches maturity, it will pupate inside the lower partition 21 and the upper partition 31;

[0027] During the pupation process of the fall armyworm, the staff can lift up the window plate 5, which is a transparent plate. One side of the window plate 5 is inserted into the inside of the cover plate 4 through a rotating shaft for rotation. The window plate 5 covers the upper part of the upper support frame 3. When the window plate 5 is lifted, the breeder can take out the fall armyworm pupae inside the upper support frame 3, which is convenient for the breeder to observe closely. After the window plate 5 is closed, the upper support frame 3 can be sealed to avoid the external environment from damaging the fall armyworm pupae as much as possible.

[0028] Among them, reinforcing plates 6 are fixedly connected to both sides of the base 1, and the sides of the two groups of reinforcing plates 6 that are close to each other are in contact with the outer wall of the cover plate 4. The reinforcing plates 6 support both sides of the base 1. When the upper support frame 3 is placed above the lower support frame 2, the reinforcing plates 6 can limit the two sides of the cover plate 4, so that the upper support frame 3 can slide vertically downward, which is convenient for aligning the lower support frame 2 with the upper support frame 3 and increasing the installation efficiency. After the lower support frame 2 and the upper support frame 3 are separated, it is convenient to clean the interior.

[0029] Preferably, a hand-operated plate 51 is provided above the window panel 5, and the hand-operated plate 51 extends to the side close to the controller 7. The hand-operated plate 51 and the window panel 5 are integrally connected to increase the structural strength. The direction of the hand-operated plate 51 is the display direction of the controller 7, which is convenient for workers to observe the controller 7 and then open the window panel 5 through the hand-operated plate 51, thereby improving work efficiency.

[0030] Specifically, a plurality of limiting grooves 23 are equidistantly formed inside the lower support frame 2, and a plurality of limiting columns 32 are fixedly connected to the lower side of the upper support frame 3 at equal intervals. The lower parts of the plurality of limiting columns 32 are respectively inserted into the plurality of limiting grooves 23. The limiting grooves 23 limit the limiting columns 32. When the lower side of the upper support frame 3 is attached to the lower support frame 2, the limiting columns 32 will be inserted into the limiting grooves 23 of the lower support frame 2, increasing the connection structure strength between the upper support frame 3 and the lower support frame 2, making it difficult for the upper support frame 3 and the lower support frame 2 to deform due to external forces, and increasing the safety during the pupation process of the internal Spodoptera frugiperda.

[0031] More specifically, a wire groove 22 is formed above the lower partition 21. The probe 8 is located on one side of the wire groove 22. A fixing pipe 81 is fixedly connected to one side of the probe 8. One end of the fixing pipe 81 is located inside the wire groove 22 and is fixedly inserted into the inner wall of the lower partition 21. The probe 8 is inserted into the wire groove 22 through the fixing pipe 81. The wire groove 22 is used for placing the data cable, hiding the data cable inside the lower partition 21 and the upper partition 31, increasing the safety of the data cable during use. At the same time, the separate setting of the lower partition 21 and the upper partition 31 facilitates the installation of the probe 8 and the fixing pipe 81.

[0032] Further in the implementation process, a plurality of limiting frames 11 are equidistantly arranged above the base 1. The upper parts of the limiting frames 11 are respectively attached to the outer walls of the plurality of lower partitions 21. When the breeder places the lower partition 21 above the base 1, the plurality of limiting frames 11 will be respectively inserted into the plurality of lower partitions 21, increasing the connection structure stability between the lower partition 21 and the base 1, making it difficult for the lower partition 21 to shake above the base 1.

[0033] The implementation principle of a pupation device for fall armyworm in corn according to an embodiment of the present application is as follows: when the breeder needs to place the pupated fall armyworm, the breeder first places the base 1 horizontally on the table, and then fixes the lower support frame 2 on the top of the base 1, and then fixes the probe 8 on the top of the lower partition 21 inside the lower support frame 2, and then one end of the probe 8 is connected to the controller 7 through a data cable, and the controller 7 mainly detects the temperature and humidity inside the lower partition 21 (the detector includes the probe, that is, the data cable, and the detector is purchased from a product currently on the market, and the specific principle is not explained here), so that personnel can intervene in the pupation process of the fall armyworm intuitively and increase the success rate of pupation, and then the breeder places the upper support frame 3 on the top of the lower support frame 2, and the lower part of the upper partition 31 will be closed with the lower partition 21, and the lower partition 21 The data line of the probe 8 is protected by the upper partition 31 to reduce the risk of being bitten by the fall armyworm. The interior of the lower partition 21 and the upper partition 31 is divided into several spaces. The fall armyworm can be placed in multiple spaces for separate breeding to avoid cannibalism among the fall armyworm larvae. Then, when the fall armyworm reaches maturity, it will pupate inside the lower partition 21 and the upper partition 31. During the pupation process of the fall armyworm, the staff can lift the window panel 5. The window panel 5 is a transparent panel. One side of the window panel 5 is inserted into the interior of the cover panel 4 through a rotating shaft for rotation. The window panel 5 covers the top of the upper support frame 3. When the window panel 5 is lifted, the breeder can take out the fall armyworm pupae inside the upper support frame 3, which is convenient for the breeder to observe closely. After the window panel 5 is closed, the upper support frame 3 can be sealed to avoid damage to the fall armyworm pupae by the external environment as much as possible.
