[0017] A method for raising grass moth adults using a simple raising device comprises the following steps:

[0018] S1: The adults of the grass moth are raised in a simple feeding device. During the ventilation process, an electric fan is started by an external power supply, so that airflow is generated inside the ventilation pipe and blown into the inside of the sleeve. By controlling the rotation speed of the electric fan, the air flow is changed. The air flow speed can be adjusted according to actual needs to provide a good living environment for the adults of the grass moth;

[0019] S2: When the electric fan rotates at the minimum speed, the air flow speed is still too high. The user can adjust the opening degree of the ventilation hole by rotating the rotating disk, and reduce the air volume entering the sleeve by changing the opening size of the first adjustment hole, thereby further reducing the air flow speed;

[0020] S3: Observe the number of eggs laid by adult grass moths through a transparent sleeve. The sleeve can be separated by separating the card slot and the card block. Add 2 to 4 overlapping sections of toilet paper to both ends of the sleeve and line them with gauze. Cover both ends with gauze and tighten the toilet paper. Wrap toilet paper around the ventilation holes for 3 circles and tighten with a rubber band. Store in a 4°C refrigerator. After all female adults die, take out the sleeves and hatch them. This will adjust the development progress of the eggs.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention can introduce fresh air by arranging a ventilation unit, maintain the freshness and quality of the air in the breeding environment, and effectively adjust the temperature and humidity to provide a more comfortable living and breeding environment for the adult grass moth. At the same time, the air flow rate can be flexibly controlled according to actual needs, thereby enhancing flexibility and adaptability. These improvement measures jointly promote the healthy growth, efficient reproduction and convenience of breeding management of the adult grass moth, and improve the overall breeding efficiency and quality.

[0023] 2. The present invention provides an air volume adjustment unit. When the electric fan rotates at the minimum speed, the air flow speed is still too large. The user can adjust the opening degree of the ventilation hole by rotating the rotating disk. The air volume entering the sleeve is reduced by changing the opening size of the first adjustment hole, thereby further reducing the air flow speed. The position of the rotating disk is fixed by a fixed disk and a damping shaft to ensure the stability of the adjusted air volume. This method increases the flexibility of adjusting the air volume.

[0024] 3. The present invention sets a disassembly mechanism, and the docking and fixing mechanism between the round box and the sleeve relies on the sliding and misalignment of the card block in the card slot. The sleeve can be moved to the bottom of the card slot by sliding; through misalignment, the card block and the fixing rod jointly ensure the fixation and stability of the sleeve.

The inner wall of the ventilation pipe 2104 is fixedly mounted with an electric fan 2105. The inner wall of the fixed block 2101 is slidably connected with a positioning rod 2106. The sliding rod 21 A positioning groove 2107 is provided on the top of 03, and the surface of the positioning rod 2106 is slidably connected to the inner cavity of the positioning groove 2107. By setting the ventilation unit 21, fresh air can be introduced to maintain the freshness and quality of the air in the breeding environment, and the temperature and humidity can be effectively adjusted to provide a more comfortable living and breeding environment for the adult grass moth. At the same time, the air flow speed can be flexibly controlled according to actual needs, which enhances flexibility and adaptability, promotes the healthy growth of the adult grass moth, efficient reproduction and convenience of breeding management, and improves the overall breeding efficiency and quality.

[0037] A stopper 2108 is fixedly installed on the top of the positioning rod 2106, and a spring 2109 is sleeved on the surface of the positioning rod 2106. One end of the spring 2109 is fixedly connected to the bottom of the stopper 2108, and the other end of the spring 2109 is fixedly connected to the top of the fixed block 2101. By setting the stopper 2108 and the spring 2109 and loosening the stopper 2108, the position of the ventilation pipe 2104 can be automatically fixed under the reaction force of the spring 2109.

[0038] A guide groove 2110 is provided on the inner wall of the sliding groove 2102, and a guide block 2111 is fixedly installed on the bottom of the sliding rod 2103.

[0039] The specific implementation of this embodiment is as follows: first, a culture dish 12 is placed in the inner cavity of a round box 11, and a sleeve 13 is placed on the surface of the culture dish 12 to wrap the culture dish 12. 10% sugar water is prepared with white sugar, and a large ball of absorbent cotton soaked in sugar water is placed on the gauze 14 at the top of the sleeve 13. The adult grass moth has a strong phototaxis and often gathers at the top of the sleeve 13 to suck the sugar water in the cotton ball through a long beak tube. A small section of folded toilet paper is placed in the culture dish 12, and a common beverage bottle cap is placed on it. The absorbent cotton ball soaked in sugar water is built in. The phototaxis of the adult grass moth can be used to remove the sleeve 13 and separate it from the round box 11. Separation, put freshly collected gray vegetable plants from the bottom of the sleeve 13, provide a habitat close to nature for the adult grass borer, which is conducive to the mating and egg-laying of the grass borer. After mating, the female grass borer likes to lay eggs on the inner wall of the cage and the gray vegetable leaves. The sleeve 13, the round box 11 and the culture dish 12 are all made of transparent materials. The number of eggs can be observed and counted through the transparent sleeve 13, and the hatching time can be judged according to the color of the eggs. When the egg-laying amount reaches 1000, most of the adults have died. 2 to 4 sections of overlapping toilet paper can be added to both ends of the sleeve 13, lined in the gauze 14, and both ends are covered with the gauze 14 and the toilet paper is tightened. The position of the ventilation hole 15 is Wrap toilet paper 3 times, tighten with rubber band, and store in a 4°C refrigerator. After all female adults die, take out the sleeve 13 for hatching. This can adjust the development progress of the eggs and maintain the uniformity of the offspring population of grass moths. The cotton balls used for feeding need to be cleaned regularly and supplemented with sugar water. When cultivating the adults of grass moths, the sleeve 13 needs to be ventilated to ensure air flow inside the sleeve 13. At this time, the user pulls the stopper 2108 to drive the positioning rod 2106 to move upward, and at the same time compresses the spring 2109, and supports the sliding rod 2103 through the sliding connection with the sliding groove 2102 through the fixed block 2101. , thereby limiting the position of the ventilation pipe 2104. When the ventilation pipe 2104 contacts the surface of the sleeve 13, the positioning groove 2107 can overlap with the bottom of the positioning rod 2106, and the block 2108 is released. Under the reaction force of the spring 2109, the position of the ventilation pipe 2104 is fixed. By starting the electric fan 2105 through an external power supply, an airflow can be generated inside the ventilation pipe 2104 and blown into the inside of the sleeve 13. By controlling the rotation speed of the electric fan 2105, the air flow can be changed. The air flow speed can be adjusted according to actual needs to provide a good living environment for the adult grass moths.

[0040] Example 2: Please refer to Figure 4 and Figure 7The present invention provides a technical solution: a simple feeding device for adult grass moths. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The adjustment mechanism 2 also includes an air volume adjustment unit 22, which is arranged on the surface of the sleeve 13. The air volume adjustment unit 22 is used to adjust the ventilation volume of the ventilation hole 15.

[0041] As a further limitation of the present invention, the air volume adjustment unit 22 includes a fixed disk 2201, which is fixedly installed on the inner wall of the ventilation hole 15. A first adjustment hole 2202 is provided on the top of the fixed disk 2201. The inner wall of the fixed disk 2201 is rotatably connected to a rotating disk 2203 through a damping shaft. A second adjustment hole 2204 is provided on the surface of the rotating disk 2203. By setting the air volume adjustment unit 22, when the electric fan 2105 rotates at the minimum speed, the air flow speed is still too large. The user can adjust the opening degree of the ventilation hole 15 by rotating the rotating disk 2203, and reduce the air volume entering the sleeve 13 by changing the opening size of the first adjustment hole 2202, thereby further reducing the air flow speed. The position of the rotating disk 2203 is fixed by the fixed disk 2201 and the damping shaft to ensure that the adjusted air volume is stable. This method increases the flexibility of adjusting the air volume.

[0042] A limiting groove 2205 is provided on the surface of the fixed disk 2201, and a limiting block 2206 is fixedly installed on the surface of the rotating disk 2203. The surface of the limiting block 2206 is slidably connected to the inner cavity of the limiting groove 2205. Through the sliding connection between the limiting groove 2205 and the limiting block 2206, the rotation angle of the rotating disk 2203 can be limited to avoid excessive rotation of the rotating disk 2203.

[0043] A placement groove 2207 is provided on the surface of the rotating disk 2203, and the inner cavity of the placement groove 2207 is slidably connected to the surface of the ventilation pipe 2104. By setting the placement groove 2207, the connection between the rotating disk 2203 and the ventilation pipe 2104 can be achieved, and the installation position of the ventilation pipe 2104 can be further determined to ensure the stability of ventilation.

[0044] The inner wall of the placement groove 2207 is rotatably connected with a disc 2208, and the surface of the disc 2208 contacts the surface of the ventilation pipe 2104. By setting the disc 2208, the disc 2208 contacts the surface of the ventilation pipe 2104. By rotating the rotating disk 2203, the friction between the ventilation pipe 2104 and the rotating disk 2203 can be reduced, making it convenient for the user to rotate the rotating disk 2203.

[0045] The specific implementation method of this embodiment is as follows: when the electric fan 2105 rotates at the minimum speed and its air flow speed is still too large, the user rotates the rotating disk 2203, and the rotating disk 2203 drives the second adjustment hole 2204 to be misaligned with the first adjustment hole 2202, thereby changing the opening degree of the first adjustment hole 2202. Through the support of the fixed disk 2201 and the damping force of the damping shaft, the position of the rotating disk 2203 after rotation can be fixed, thereby adjusting the ventilation hole 15, thereby reducing the air volume entering the sleeve 13, further adjusting the air flow speed, and further increasing the flexibility of adjusting the air volume.

[0046] Example 3: Please refer to Figure 5 and Figure 6 The present invention provides a technical solution: a simple feeding device for adult grass moths. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. A disassembly mechanism 3 is provided on the inner wall of the round box 11, and the disassembly mechanism 3 is used to facilitate the disassembly of the sleeve 13.

[0047] As a further limitation of the present invention, the disassembly mechanism 3 includes a slot 301, which is opened on the inner wall of the round box 11, and a block 302 is fixedly installed on the surface of the sleeve 13, and the surface of the block 302 is movably connected to the inner wall of the slot 301, and an elastic clip 304 is fixedly installed on the inner wall of the slot 301, and a fixing rod 303 is fixedly installed on the inner wall of the block 302, and the surface of the fixing rod 303 contacts the inner side of the elastic clip 304. By setting the disassembly mechanism 3, the docking and fixing mechanism between the round box 11 and the sleeve 13 depends on the sliding and misalignment of the block 302 in the slot 301. By sliding, the sleeve 13 can be moved to the bottom of the slot 301; by misalignment, the block 302 and the fixing rod 303 jointly ensure the fixation and stability of the sleeve 13. When separation is required, the sleeve 13 can be easily separated by rotating the sleeve 13 to align the block 302 with the opening of the slot 301.

[0048] The specific implementation of this embodiment is as follows: when the round box 11 and the sleeve 13 are docked, the sleeve 13 can be moved to the bottom of the slot 301 by sliding the block 302 in the inner cavity of the slot 301. At the same time, the sleeve 13 is rotated to misalign the block 302 with the slot 301, and the fixing rod 303 enters the inner side of the elastic clip 304 to complete the position fixation of the sleeve 13. When separation is required, the user only needs to rotate the sleeve 13 and overlap it with the opening of the slot 301 to achieve the separation between the round box 11 and the sleeve 13. The misalignment of the block 302 and the slot 301 can increase the stability of the sleeve 13 during operation.

[0049] A method for raising grass moth adults using a simple raising device comprises the following steps:

[0050] S1: The adult grass moth is raised in a simple feeding device. During ventilation, the electric fan 2105 is started by an external power supply, so that airflow is generated inside the ventilation pipe 2104 and blown into the inside of the sleeve 13. By controlling the rotation speed of the electric fan 2105, the air flow is changed. The air flow speed can be adjusted according to actual needs to provide a good living environment for the adult grass moth;

[0051] S2: When the electric fan 2105 rotates at the minimum speed, the air flow speed is still too high. The user can adjust the opening degree of the ventilation hole 15 by rotating the rotating disk 2203, and reduce the air volume entering the sleeve 13 by changing the opening size of the first adjustment hole 2202, thereby further reducing the air flow speed;

[0052] S3: Through the transparent sleeve 13, the number of eggs laid by the adult grass moth is observed. The sleeve 13 can be separated by separating the card slot 301 and the card block 302. 2 to 4 sections of overlapping toilet paper can be added to both ends of the sleeve 13 and lined in the gauze 14. Both ends are covered with the gauze 14 and tightened with toilet paper. The ventilation hole 15 is wrapped with toilet paper for 3 circles and tightened with a rubber band. It is stored in a 4°C refrigerator. After all the female adults die, the sleeve 13 is taken out and hatched uniformly. In this way, the development progress of the eggs can be adjusted.

During ventilation, an electric fan (2105) is started by an external power supply, so that airflow is generated inside the ventilation pipe (2104) and blown into the inside of the sleeve (13). By controlling the rotation speed of the electric fan (2105), the air flow is changed. The air flow speed can be adjusted according to actual needs to provide a good living environment for the adult grass moth; S2: When the electric fan (2105) rotates at the minimum speed, the air flow speed is still too high. The user can adjust the opening degree of the ventilation hole (15) by rotating the rotating disk (2203), and reduce the air volume entering the sleeve (13) by changing the opening size of the first adjustment hole (2202), thereby further reducing the air flow speed; S3: The number of eggs laid by the adult grass moth is observed through the transparent sleeve (13). The sleeve (13) can be separated by separating the card slot (301) and the card block (302). Two to four overlapping sections of toilet paper can be added to both ends of the sleeve (13) and lined in the gauze (14). Both ends are covered with the gauze (14) and tightened with toilet paper. The ventilation hole (15) is wrapped with toilet paper for three turns and tightened with a rubber band. The ventilating hole (15) is stored in a 4°C refrigerator. After all the female adults die, the sleeve (13) is taken out uniformly for hatching. In this way, the development progress of the eggs can be adjusted.
