[0001] The present invention belongs to the technical field of biological control, and particularly relates to a rearing device for Amblyseius swirskii and a rearing method thereof. Background Art

[0002] As an efficient predatory natural enemy, Amblyseius swirskii is widely used in the biological control of agricultural pests. Its predation range covers main agricultural pests such as whiteflies, thrips, and tarsonemid mites, and it is particularly outstanding in controlling Bemisia tabaci. With the increasing global demand for green agriculture and the reduction of chemical pesticides, large-scale production of Amblyseius swirskii has become the core link in the development of biological control technology.

[0003] In the prior art, most rearing devices for Amblyseius swirskii can usually only spray water on the surface of the rearing substrate, unable to ensure the humidity of the rearing substrate in different areas, and it is difficult to meet the humidity environment requirements of Amblyseius swirskii. In terms of ventilation, the device usually can only ventilate through the upper part of the bottle cap, resulting in insufficient air circulation. This makes it difficult to guarantee the survival rate and activity of Amblyseius swirskii during large-scale rearing, seriously affecting the application and popularization of biological control technology.

[0004] That is, in the existing rearing devices for Amblyseius swirskii, there are large differences in the humidity of the rearing substrate in different areas, the ventilation design is poor, and the air circulation is insufficient, resulting in low survival rate and activity of mites during large-scale rearing. Summary of the Invention

[0020] A plurality of rectangular water outlet holes are opened on both sides of the outer surface of the filtering sleeve. The distance between the two ends of the rectangular hole is the same as the length of the top end of the inclined groove body, and the distance between the upper and lower two water outlet holes is the same as the height of the inclined groove body, for providing a water outlet channel for the humidity adjustment core body.

[0029] Beneficial effects:

[0030] The present invention provides a rearing device for *Amblyseius swirskii*. The rearing device for *Amblyseius swirskii* includes a bottle body, a bottle cap and an adjusting structure.

[0031] By rotating the adjustment ring, the size of the overlapping area between the water outlet holes and the inclined trough is changed, thereby changing the size of the path through which the humidity-adjusting core can transfer moisture to the breeding substrate. At the same time, due to the inclined trough, the moisture gradient absorbed by the breeding substrate decreases, reducing the difference in humidity between the upper breeding substrate with a high air permeability and a low humidity and the lower breeding substrate with a low air permeability and a high humidity, reducing the humidity of the breeding substrate in different regions, meeting the humidity environment requirements of Amblyseius swirskii, and at the same time avoiding the problem that the internal Amblyseius swirskii is likely to escape when the bottle cap is frequently opened.

Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0042] Such as Figures 1 to 5As shown in the figure, the present invention provides a rearing device for Amblyseius swirskii. This rearing device for Amblyseius swirskii includes a bottle body 1, a bottle cap 2 and an adjustment structure. The bottle body 1 is used to accommodate Amblyseius swirskii and the rearing substrate. The bottle cap 2 is threadedly connected to the opening of the bottle body 1. A ventilation net is provided above the bottle cap 2. The bottle cap 2 is used to prevent Amblyseius swirskii from escaping while allowing the internal gas of the bottle body 1 to circulate. The adjustment structure includes a humidity-adjusting core 3, a filter sleeve 4 and an adjustment ring 5. The filter sleeve 4 is connected to the bottle body 1. An installation groove is provided on the bottle cap 2. The adjustment ring 5 is inserted into the installation groove. An inclined groove body is provided on the outer surface of the adjustment ring 5. The horizontal distance between the left and right ends of the inclined groove body decreases in a gradient along the circumferential direction of the adjustment ring 5 towards the hygroscopic rope 6, which is used to adjust the size of the gap between the humidity-adjusting core 3 and the filter sleeve 4. A plurality of rectangular water outlet holes are opened on both sides of the outer surface of the filter sleeve 4. The distance between the two ends of the rectangular hole is the same as the length of the top end of the inclined groove body, and the distance between the upper and lower two water outlet holes is the same as the height of the inclined groove body, which is used to provide a water outlet channel for the humidity-adjusting core 3. Rotating the adjustment ring 5 is used to change the size of the overlapping area between the water outlet hole and the inclined groove body. The humidity-adjusting core 3 is inserted into the adjustment ring 5. A sealing sleeve 10 is provided at the top of the filter sleeve 4. When the bottle cap 2 and the bottle body 1 are installed, the sealing sleeve 10 is used to seal the gap between the filter sleeve 4 and the bottle cap 2. A hydrophobic membrane 12 is provided on the filter sleeve 4, which is used to prevent Amblyseius swirskii from contacting the humidity-adjusting core 3.

[0043] By rotating the adjustment ring 5, the size of the overlapping area between the water outlet hole and the inclined groove body is changed, thereby changing the size of the path through which the humidity-adjusting core 3 can transfer moisture to the rearing substrate. At the same time, due to the shape of the inclined groove body, the moisture gradient absorbed by the rearing substrate from top to bottom decreases, avoiding the problem that the upper rearing substrate has a lower humidity due to a high air permeability and the lower rearing substrate has a higher humidity due to a low air permeability, reducing the humidity of the rearing substrate in different regions, meeting the humidity environment requirements of Amblyseius swirskii. In order to reduce the evaporation rate of the humidity of the humidity-adjusting core 3, a sealing cover 13 is snap-fitted and installed at the top of the adjustment ring 5. By pulling out the adjustment ring 5 in the installation groove, air can enter the inside of the bottle body 1 from the filter sleeve 4, which can expand the area of the inside of the bottle body 1 in contact with air, thereby increasing the air permeability at the bottom end of the inside of the bottle body 1.

[0044] When in use, first place Amblyseius swirskii and the breeding substrate in the bottle body 1, tighten the bottle cap 2, and the sealing sleeve 10 adheres to the bottom end of the bottle cap 2 to prevent Amblyseius swirskii from drilling into the inside of the filter sleeve 4 from the connection between the bottle cap 2 and the filter sleeve 4. Then, after injecting water into the humidity adjustment core 3, insert it into the adjustment ring 5. Next, insert the adjustment ring 5 into the installation groove. Then, rotate the sealing cover 13, and the sealing cover 13 drives the adjustment ring 5 to rotate. At this time, observe the size of the overlapping area between the inclined groove body and the water outlet hole. The size of this overlapping area is the size of the path for the humidity adjustment core 3 to transfer moisture to the breeding substrate. By adjusting the size of the above overlapping area, the moisture release amount of the humidity adjustment core 3 is changed, thereby reducing the difference in the moisture release amount of the humidity adjustment core 3 required for the breeding substrate. When it is necessary to know the humidity of the breeding substrate, open the sealing cover 13 to take out the humidity adjustment core 3, and judge the humidity of the breeding substrate by observing, touching and squeezing the humidity adjustment core 3. By pulling out the adjustment ring 5, air enters the inside of the bottle body 1 from the water outlet hole on the filter sleeve 4, improving the air permeability.

[0045] Specifically, the humidity adjustment core 3 is a sponge, or it can be other substances with strong water storage capacity and uniform and stable water release; the hydrophobic film 12 is made of high-molecular hydrophobic materials such as polytetrafluoroethylene, and has a microporous structure, which can not only prevent Amblyseius swirskii from contacting the humidity adjustment core 3, but also does not prevent moisture conduction and gas exchange; a thermochromic powder can be added to the humidity adjustment core 3, and the humidity of the humidity adjustment core 3 can be intuitively reflected by the change in the color of the thermochromic powder.

[0046] In this embodiment, the filter sleeve 4 is fixedly installed at the central position of the bottom end of the bottle body 1, the adjustment ring 5 is rotatably installed in the installation groove, the humidity adjustment core 3 is movably clamped and installed inside the adjustment ring 5, and the bottle body 1 is made of a transparent material.

[0047] See Figure 2 and Figure 3 As shown in and, the moisture conduction structure includes a moisture absorption rope 6 and a transfer structure. The moisture absorption rope 6 is connected to the humidity adjustment core 3 and is used to conduct the moisture of the humidity adjustment core 3. The transfer structure includes a moisture conduction cotton strip 7, a breathable shell 8 and an extrusion assembly. The moisture conduction cotton strip 7 is connected to the moisture absorption rope 6 and is used to conduct and diffuse the water adsorbed by the moisture absorption rope 6 to the breeding substrate in different areas of the bottle body 1. The breathable shell 8 is connected to the bottle body 1, and the breathable shell 8 is used to prevent Amblyseius swirskii from drilling into the moisture conduction cotton strip 7. The extrusion assembly is connected to the bottle body 1, and the extrusion assembly is used to extrude the moisture conduction cotton strip 7. The extrusion assembly includes a spring plate 14 and a button 15. The spring plate 14 is connected to the bottle body 1, and the spring plate 14 is used to extrude the moisture conduction cotton strip 7. The button 15 is connected to the spring plate 14, and the button 15 is used to push the spring plate 14. A positioning hole is provided on the bottle body 1, and the button 15 is inserted into the positioning hole. A water conduction connector 11 is provided on the filter sleeve 4, and the humidity adjustment core 3 and the moisture absorption rope 6 are respectively located on the upper and lower sides of the water conduction connector 11.

[0048] The humidity-adjusting core 3 is connected by a moisture-absorbing rope 6, and moisture is conducted to the moisture-conducting cotton strip 7. The moisture-conducting cotton strip 7 diffuses the moisture to the breeding substrates in different areas of the bottle body 1, realizing moisture dispersion, reducing the humidity difference in the environment of the Amblyseius swirskii, and at the same time, the breathable shell 8 is fixed inside the bottle body 1 and sleeved outside the moisture-conducting cotton strip 7 to prevent mites from drilling in. The water-permeable sleeve 9 wraps the moisture-absorbing rope 6 to prevent mites from attaching, ensuring the stable operation of the moisture-conducting function. The water-conducting connector 11 makes the moisture conduction between the humidity-adjusting core 3 and the moisture-absorbing rope 6 more stable, improving the moisture-conducting efficiency. By pressing the button 15, the spring plate 14 is pushed to squeeze the moisture-conducting cotton strip 7, so that the moisture on the moisture-conducting cotton strip 7 is better transferred to the breeding substrate.

[0049] The moisture on the humidity-adjusting core 3 is more fully transferred to the moisture-absorbing rope 6 through the water-conducting connector 11, and then the moisture is transferred to the moisture-conducting cotton strip 7 through the moisture-absorbing rope 6. The moisture-conducting cotton strip 7 replenishes moisture to the breeding substrates near the moisture-conducting cotton strip 7 through the breathable shell 8. Then, when observing the humidity inside the bottle body 1, by pressing the button 15, the button 15 pushes the spring plate 14 to squeeze the moisture in the moisture-conducting cotton strip 7, so that the moisture in the moisture-conducting cotton strip 7 is more fully absorbed by the breeding substrate.

[0050] Specifically, thermochromic powder is added to the moisture-conducting cotton strip 7. The microcapsules in the thermochromic powder contain a color-changing pigment. Water will affect the internal chemical reaction, change the molecular structure of the pigment, and thus change the color. Through the change in the color of the thermochromic powder, the moisture content of the moisture-conducting cotton strip 7 is intuitively reflected; the spring plate 14 is made of a transparent material, and the color change of the thermochromic powder on the moisture-conducting cotton strip 7 can be directly seen through the bottle body 1 and the spring plate 14 of the housing.

[0051] In this embodiment, the water-permeable sleeve 9 passes through the filter sleeve 4 and is connected to the water-conducting connector 11. There are four groups of breathable shells 8, which are evenly distributed on the inner wall of the bottle body 1 with the filter sleeve 4 as the central axis. The water-conducting connector 11 is a sponge block, and it can also be other substances with uniform and stable moisture release.

[0052] A breeding method for a breeding device of Amblyseius swirskii includes the following steps:

[0053] Step 1: When the device is enabled, put the Amblyseius swirskii and the breeding substrate into the bottle body 1, cover the bottle cap 2, and put the adjusting ring 5 and the humidity-adjusting core 3 into the installation groove.

[0054] Step 2: Humidity adjustment, inject water into the humidity-adjusting core 3 from the installation groove, rotate the adjusting ring 5, change the covering area of the filter sleeve 4 on the humidity-adjusting core 3 through the inclined groove body, adjust the gap between the humidity-adjusting core 3 and the filter sleeve 4, and control the amount of moisture released to the breeding substrate.

[0055] Step 3: Moisture-conducting maintenance, use the moisture-absorbing rope 6 to conduct the moisture of the humidity-adjusting core 3, and diffuse the moisture to the breeding substrates in different areas of the bottle body 1 through the moisture-conducting cotton strip 7 to reduce the humidity difference of the breeding substrates in different areas.

[0056] Step 4: Maintenance management. Regularly check the mite-proof status of the breathable shell 8 and the water-permeable sleeve 9 to ensure that Amblyseius swirskii does not drill into the moisture-conducting cotton strip 7 or attach to the moisture-absorbing rope 6, maintain the normal operation of the device, regularly extract the humidity-adjusting core 3 to understand the humidity distribution inside the bottle. When the internal humidity is high, rotate the adjusting ring 5 to narrow or seal the gap between the humidity-adjusting core 3 and the filter sleeve 4, and reduce the transmission of moisture from the moisture-conducting cotton strip 7 to the breeding substrate.

[0057] Step 5: Breathing optimization. Extract the adjusting ring 5 and the humidity-adjusting core 3 from the installation groove to improve the air circulation inside the bottle to meet the device maintenance requirements or the requirements of Amblyseius swirskii for a breathable environment.

[0058] The following is the specific use process of a breeding device for Amblyseius swirskii:

[0059] First, place Amblyseius swirskii and the breeding substrate in the bottle body 1, then tighten the bottle cap 2, and the sealing sleeve 10 is attached to the bottom end of the bottle cap 2 to prevent Amblyseius swirskii from drilling into the inside of the filter sleeve 4 from the connection between the bottle cap 2 and the filter sleeve 4. Then, after filling the humidity-adjusting core 3 with water, insert it into the adjusting ring 5, then insert the adjusting ring 5 into the installation groove, and then rotate the sealing cover 13. The sealing cover 13 drives the adjusting ring 5 to rotate. At this time, observe the size of the overlapping area between the diagonal groove and the water outlet hole. The size of this overlapping area is the size of the path for the humidity-adjusting core 3 to transfer moisture to the breeding substrate. By adjusting the size of the overlapping area, the moisture release amount of the humidity-adjusting core 3 is changed, so as to reduce the difference in the moisture release amount of the humidity-adjusting core 3 required by the breeding substrate. At the same time, the moisture on the humidity-adjusting core 3 is more fully transferred to the moisture-absorbing rope 6 through the water-conducting connector 11, and then the moisture is transferred to the moisture-conducting cotton strip 7 through the moisture-absorbing rope 6. The moisture-conducting cotton strip 7 replenishes moisture to the breeding substrate near the moisture-conducting cotton strip 7 through the breathable shell 8. Then, when observing the humidity inside the bottle body 1, the button 15 can be pressed. The button 15 pushes the spring plate 14 to squeeze the moisture in the moisture-conducting cotton strip 7, so that the moisture in the moisture-conducting cotton strip 7 is more fully absorbed by the breeding substrate. When it is necessary to know the humidity of the breeding substrate, the humidity-adjusting core 3 is taken out by opening the sealing cover 13, and the humidity of the breeding substrate is judged by observing, touching and squeezing the humidity-adjusting core 3. By extracting the adjusting ring 5, air enters the inside of the bottle body 1 from the water outlet hole on the filter sleeve 4, improving the air permeability.

[0060] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.

Use the moisture absorption rope (6) to conduct the moisture of the humidity adjustment core (3), and diffuse the moisture to the breeding substrates in different areas of the bottle body (1) through the moisture conduction cotton strip (7). Step 4: Maintenance management. Regularly check the mite-proof status of the breathable shell (8) and the water-permeable sleeve (9) to ensure that Amblyseius swirskii does not drill into the moisture conduction cotton strip (7) or attach to the moisture absorption rope (6). Regularly extract the humidity adjustment core (3) to understand the humidity distribution in the bottle. Rotate the adjustment ring (5) to narrow or seal the gap between the humidity adjustment core (3) and the filter sleeve (4), reducing the moisture transmission from the moisture conduction cotton strip (7) to the breeding substrate. Step 5: Breathability optimization. Extract the adjustment ring (5) and the humidity adjustment core (3) from the installation groove to allow the bottle body (1) to breathe through the filter sleeve (4).
