Description

Technical Field

[0001] This invention belongs to the field of biological control technology, and in particular relates to an insect release device for biological control. Background Technology

[0002] The rice stem borer, commonly known as the "stem borer," "stem borer," or "whitehead borer," belongs to the genus *Paecilomyces* of the family Pyralidae in the order Lepidoptera. It is characterized by multiple generations per year, severe damage, and a wide range of infestations. It is one of the most common and difficult-to-control pests in rice production. It bores into the rice stems, initially causing sheath dieback, which later develops into dead hearts and whiteheads in severe infestations. The borer also weakens the rice plants, leading to lodging and further indirect losses. In normal years, it can cause a 10% yield loss, while in severe cases, losses can exceed 50%.

[0003] Biological control is a green pest control method that uses only natural enemy insects, insect pathogenic fungi, or viruses to control pests, without posing any burden to human health or environmental safety. Among these, Trichogramma wasps are the number one natural enemy of agricultural lepidopteran pests and have received widespread attention from agricultural practitioners. They parasitize the eggs of target pests, thereby preventing the eggs from hatching or preventing the larvae from completing their normal life cycle, thus achieving a control effect.

[0004] Currently, the release of Trichogramma wasps mainly relies on bee cards. However, the number of wasps released from these cards is greatly affected by the environment, making precise control of the release amount impossible. Insufficient release due to weather conditions can severely impact the control effect. Another biological control method utilizes entomopathogenic fungi (Beauveria bassiana, Metarhizium anisopliae) to infect and kill insect larvae. Because these fungi are highly specific, effective only against the target pests, they do not affect other natural enemies. However, pests can only be infected after contact with the pathogenic fungi. Therefore, using this method involves releasing insects first and then manually spraying them with the pathogenic fungi, resulting in a waste of human resources and reducing the effectiveness of biological control.

[0007] In this embodiment of the invention, the insect release device for biological control further includes an adsorbent material attachment device, which includes an adsorbent material attachment chamber and an adsorbent material storage chamber. The adsorbent material attachment chamber is located between the insect storage chamber and the pathogen attachment chamber, so that the insects in the insect storage chamber enter the adsorbent material attachment chamber and the pathogen attachment chamber in sequence. The adsorbent material storage chamber is connected to the adsorbent material attachment chamber and is used to provide adsorbent material to the adsorbent material attachment chamber.

[0008] In this embodiment of the invention, a first electric door is provided between the insect storage chamber and the adsorbent material attachment chamber. The insect release device for biological control also includes a control device, which includes a controller and a first pass-through quantity sensor placed between the insect storage chamber and the adsorbent material attachment chamber for counting the number of insects entering the adsorbent material attachment chamber.

The control device also includes a second pass-through sensor placed between the adsorption material attachment chamber and the pathogen attachment chamber for counting the number of insects entering the pathogen attachment chamber. The controller is communicatively connected to the second pass-through sensor and the second electric door.

[0010] In this embodiment of the invention, there are two pathogen storage chambers, which are located on the upper and lower sides of the pathogen attachment chamber. The pathogen storage chambers are rotatably installed, and a first screen body is provided between each of the two pathogen storage chambers and the pathogen attachment chamber. The sieve aperture of the first screen body is larger than the size of the pathogen body but smaller than the size of the insect.

[0011] In this embodiment of the invention, there are two adsorbent material storage chambers, which are respectively located on the upper and lower sides of the adsorbent material attachment chamber. The adsorbent material storage chambers are rotatably installed, and a second screen body is provided between each of the two adsorbent material storage chambers and the adsorbent material attachment chamber. The sieve aperture of the second screen body is larger than the size of the adsorbent material and smaller than the size of the insect.

[0012] In this embodiment of the invention, the insect release device for biological control also includes a hollow rotating shaft that connects an adsorbent material storage chamber and a pathogen storage chamber in series, with both ends of the hollow rotating shaft rotatably connected to the insect storage chamber and the insect release chamber, respectively.

[0013] In this embodiment of the invention, the control device further includes a third pass-through quantity sensor placed at the outlet of the insect release chamber and used to count the number of insects leaving the insect release chamber, and the controller is communicatively connected to the third pass-through quantity sensor.

[0016] Through the above technical solutions, the insect release device for biological control provided in the embodiments of the present invention has the following beneficial effects:

[0017] When the above-mentioned biological control insect release device is used to control the rice stem borer, it includes an insect storage chamber, a pathogen attachment device, and an insect release chamber. The pathogen attachment device includes a pathogen attachment chamber and a pathogen storage chamber. The pathogen attachment chamber is connected to the insect storage chamber so that insects (Trichogramma wasps) in the insect storage chamber can enter the pathogen attachment chamber. The pathogen storage chamber is connected to the pathogen attachment chamber and is used to provide pathogens to the pathogen attachment chamber. The insect release chamber is connected to the pathogen attachment chamber and is used to release insects with pathogens attached to them from the pathogen attachment chamber. When the insects enter the pathogen attachment chamber from the insect storage chamber, the pathogens in the pathogen storage chamber enter the pathogen attachment chamber and attach to the surface of the insects that have entered the pathogen attachment chamber. The insects that have completed the pathogen attachment are then released out of the biological control insect release device through the insect release chamber to achieve the effect of biological control. Compared with the existing technology that involves releasing insects first and then manually spraying pathogens on them, this invention allows the insects to carry pathogens at the same time as they are released, which can save the step of manual spraying. Moreover, the insects carrying pathogens have a better effect and can effectively improve the biological control effect.

[0033] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0034] The rice stem borer, commonly known as the "stem borer," "stem borer," or "whitehead borer," belongs to the genus *Paecilomyces* of the family Pyralidae in the order Lepidoptera. It is characterized by multiple generations per year, severe damage, and a wide range of infestations. It is one of the most common and difficult-to-control pests in rice production. It bores into the rice stems, initially causing sheath dieback, which later develops into dead hearts and whiteheads in severe infestations. The borer also weakens the rice plants, leading to lodging and further indirect losses. In normal years, it can cause a 10% yield loss, while in severe cases, losses can exceed 50%.

[0035] Biological control is a green pest control method that uses only natural enemy insects, insect pathogenic fungi, or viruses to control pests, without posing any burden to human health or environmental safety. Among these, Trichogramma wasps are the number one natural enemy of agricultural lepidopteran pests and have received widespread attention from agricultural practitioners. They parasitize the eggs of target pests, thereby preventing the eggs from hatching or preventing the larvae from completing their normal life cycle, thus achieving a control effect.

[0036] Currently, the release of Trichogramma wasps mainly relies on bee cards. However, the number of wasps released from these cards is greatly affected by the environment, making precise control of the release amount impossible. Insufficient release due to weather conditions can severely impact the control effect. Another biological control method utilizes entomopathogenic fungi (Beauveria bassiana, Metarhizium anisopliae) to infect and kill insect larvae. Because these fungi are highly specific, effective only against the target pests, they do not affect other natural enemies. However, pests can only be infected after contact with the pathogenic fungi. Therefore, using this method involves releasing insects first and then manually spraying them with the pathogenic fungi, resulting in a waste of human resources and reducing the effectiveness of biological control.

[0037] Based on this, the present application provides an insect release device for biological control, which aims to solve the technical problems of wasted human resources and poor biological control effect caused by the operation of releasing insects first and then manually spraying pathogenic fungi on the insects in biological control.

[0038] The following description, with reference to the accompanying drawings, describes an insect release device for biological control according to the present invention.

[0039] like Figure 1 and Figure 2 As shown, in an embodiment of the present invention, a biological control insect release device is provided, wherein the biological control insect release device includes:

[0040] Insect storage compartment 100, used for storing insects;

[0041] The pathogen attachment device 200 includes a pathogen attachment chamber 201 and a pathogen storage chamber 202. The pathogen attachment chamber 201 is connected to the insect storage chamber 100 so that insects in the insect storage chamber 100 can enter the pathogen attachment chamber 201. The pathogen storage chamber 202 is connected to the pathogen attachment chamber 201 and is used to provide pathogens to the pathogen attachment chamber 201.

[0042] The insect release chamber 300 is connected to the pathogen attachment chamber 201 and is used to release insects with pathogens attached to them from the pathogen attachment chamber 201.

[0043] When the above-mentioned biological control insect release equipment is used to control rice stem borers, it includes an insect storage chamber 100, a pathogen attachment device 200, and an insect release chamber 300. The pathogen attachment device 200 includes a pathogen attachment chamber 201 and a pathogen storage chamber 202. The pathogen attachment chamber 201 is connected to the insect storage chamber 100 so that insects (Trichogramma wasps) in the insect storage chamber 100 can enter the pathogen attachment chamber 201. The pathogen storage chamber 202 is connected to the pathogen attachment chamber 201 and is used to provide pathogens to the pathogen attachment chamber 201. The insect release chamber 300 is connected to the pathogen attachment chamber 201 and is used to release the pathogens attached to the pathogen attachment chamber 201. The insects are released from the insect storage chamber 100 into the pathogen attachment chamber 201. Pathogens from the storage chamber 202 then enter the attachment chamber 201 and attach to the insects. The insects, now pathogen-attached, are released through the release chamber 300 outside the biological control insect release device to achieve biological control. Compared to existing technologies that release insects first and then manually spray them with pathogens, this invention releases insects carrying pathogens, eliminating the need for manual spraying. Furthermore, the pathogen-carrying insects provide a better biological control effect. It should be noted that the biological control insect release device of this invention is particularly suitable for controlling rice stem borers using Trichogramma wasps. However, using the same device to control other pests should also fall within the scope of this invention.

[0044] See Figure 1 and Figure 2 In this embodiment of the invention, the insect release device for biological control further includes an adsorbent material attachment device 203. The adsorbent material attachment device 203 includes an adsorbent material attachment chamber 204 and an adsorbent material storage chamber 205. The adsorbent material attachment chamber 204 is located between the insect storage chamber 100 and the pathogen attachment chamber 201, allowing insects in the insect storage chamber 100 to sequentially enter the adsorbent material attachment chamber 204 and the pathogen attachment chamber 201. The adsorbent material storage chamber 205 is connected to the adsorbent material attachment chamber 204 and provides adsorbent material to the adsorbent material attachment chamber 204. That is, the adsorbent material stored in the adsorbent material storage chamber 205 enters the adsorbent material attachment chamber 204 and comes into contact with and adsorbs the insects. The adsorbent material adheres to the insect's body surface to increase the adsorption area on the insect's body surface and its ability to adsorb pathogens.

[0045] Specifically, the adsorbent material can be a nanomaterial, specifically a nanocrystalline chitosan, and the pathogen can be Beauveria bassiana, specifically a coccidial Beauveria bassiana, which can produce conidia through asexual reproduction. Of course, the present invention is not limited to this, and the adsorbent material and pathogen can also be other materials and pathogens.

[0046] See Figure 2In this embodiment of the invention, a first electric door 206 is provided between the insect storage chamber 100 and the adsorbent material attachment chamber 204. The insect release device for biological control also includes a control device 207. The control device 207 includes a controller 400 and a first pass-through quantity sensor placed between the insect storage chamber 100 and the adsorbent material attachment chamber 204 for counting the number of insects entering the adsorbent material attachment chamber 204. The controller 400 is communicatively connected to both the first pass-through quantity sensor and the first electric door 206. That is, the first electric door 206 is used to control the connection and closure between the insect storage chamber 100 and the adsorbent material attachment chamber 204, thereby restricting the activity space of the insects. The first pass-through quantity sensor is used to count the number of insects entering the adsorbent material attachment chamber 204 from the insect storage chamber 100 to obtain the number of insects with adsorbent material attached. The controller 400 controls the opening and closing of the first electric door 206 by receiving the signal from the first pass-through quantity sensor.

[0047] Specifically, a circular tube is provided between the insect storage chamber 100 and the adsorption material attachment chamber 204. One end of the circular tube is connected to the insect storage chamber 100, and the other end of the circular tube is connected to the adsorption material attachment chamber 204. The first electric door 206 can be a rotatable circular plate that fits with the inner wall of the circular tube. When the plane of the circular plate rotates to be parallel to the cross-section of the circular tube, the circular plate, i.e. the first electric door 206, can separate the insect storage chamber 100 from the adsorption material attachment chamber 204.

[0048] See Figure 2 In this embodiment of the invention, a second electric door 208 is provided between the adsorption material attachment chamber 204 and the pathogen attachment chamber 201. The control device 207 also includes a second passage quantity sensor placed between the adsorption material attachment chamber 204 and the pathogen attachment chamber 201 for counting the number of insects entering the pathogen attachment chamber 201. The controller 400 is communicatively connected to the second passage quantity sensor and the second electric door 208. That is, the second electric door 208 is used to control the connection and closure between the adsorption material attachment chamber 204 and the pathogen attachment chamber 201, thereby restricting the activity space of insects. The second passage quantity sensor is used to count the number of insects entering the pathogen attachment chamber 201 from the adsorption material attachment chamber 204 to obtain the number of insects with adsorption material and pathogens attached. The controller 400 controls the opening and closing of the second electric door 208 by receiving the signal from the second passage quantity sensor.

[0049] See Figure 1 and Figure 2In this embodiment of the invention, there are two pathogen storage chambers 202, which are respectively located on the upper and lower sides of the pathogen attachment chamber 201. The pathogen storage chambers 202 are rotatably installed, and a first screen body 209 is provided between each of the two pathogen storage chambers 202 and the pathogen attachment chamber 201. The sieve aperture of the first screen body 209 is larger than the size of the pathogen and smaller than the size of the insect. The pathogen storage chamber 202 is used to store pathogens. Since the sieve aperture of the first screen body 209 is larger than the size of the pathogens, the pathogens in the upper pathogen storage chamber 202 fall into the pathogen attachment chamber 201 due to their own gravity to attach to the insect's body surface. The remaining pathogens continue to fall into the lower pathogen storage chamber 202. Since the pathogen storage chamber 202 is rotatably installed, the two pathogen storage chambers 202 can be inverted. Since the size of the insect is larger than the sieve aperture of the first screen body 209, the insect can only move in the pathogen attachment chamber 201. The pathogens can fall and attach multiple times, which can improve the attachment effect of the pathogens.

[0050] Specifically, one of the pathogen storage chambers 202 is provided with a pathogen inlet. The inner wall of the pathogen inlet is provided with a first internal thread. The inner wall of the pathogen inlet is threadedly connected to a first cap 214. By rotating the first cap 214, the pathogen inlet can be opened to load pathogens into the pathogen storage chamber 202.

[0051] See figure Figure 1 and Figure 2 In this embodiment of the invention, there are two adsorbent material storage chambers 205, which are respectively located on the upper and lower sides of the adsorbent material attachment chamber 204. The adsorbent material storage chambers 205 are rotatably installed, and a second screen body 210 is provided between each of the two adsorbent material storage chambers 205 and the adsorbent material attachment chamber 204. The sieve aperture of the second screen body 210 is larger than the size of the adsorbent material and smaller than the size of the insect. The adsorbent material storage chamber 205 is used to store adsorbent material. Since the sieve aperture of the second screen body 210 is larger than the size of the adsorbent material, the adsorbent material in the upper adsorbent material storage chamber 205 falls into the adsorbent material attachment chamber 204 due to its own gravity to attach to the insect's body surface. The remaining adsorbent material continues to fall into the lower adsorbent material storage chamber 205. Since the adsorbent material storage chamber 205 is rotatably installed, the two adsorbent material storage chambers 205 can be inverted. Since the size of the insect is larger than the sieve aperture of the second screen body 210, the insect can only move in the adsorbent material attachment chamber 204. The adsorbent material can achieve multiple falls and attachments, which can improve the attachment effect of the adsorbent material.

[0052] Specifically, one of the adsorbent material storage chambers 205 is provided with an adsorbent material inlet. The inner wall of the adsorbent material inlet is provided with a second internal thread. The inner wall of the adsorbent material inlet is threadedly connected to a second cap 215. By rotating the second cap 215, the adsorbent material inlet can be opened to load the adsorbent material into the adsorbent material storage chamber 205.

[0053] See Figure 2 In this embodiment of the invention, the insect release device for biological control further includes a hollow rotating shaft 211 connecting the adsorbent material storage chamber 205 and the pathogen storage chamber 202 in series. The two ends of the hollow rotating shaft 211 are rotatably connected to the insect storage chamber 100 and the insect release chamber 300, respectively. That is, the rotation of the hollow rotating shaft 211 drives the adsorbent material storage chamber 205 and the pathogen storage chamber 202 to rotate. The adsorbent material storage chamber 205 and the pathogen storage chamber 202 are connected in series via the hollow rotating shaft 211 so that they can rotate synchronously, simplifying the structure of the device. The hollow design of the hollow rotating shaft 211 allows insects to smoothly enter the insect release chamber 300 and await release. Specifically, the hollow rotating shaft 211 is driven to rotate by a drive motor.

[0054] See Figure 2 In this embodiment of the invention, the control device 207 further includes a third through-count sensor located at the outlet of the insect release chamber 300 and used to count the number of insects leaving the insect release chamber 300. The controller 400 is communicatively connected to the third through-count sensor. That is, the third through-count sensor is used to count the insects released from the insect release chamber 300 to obtain the final number of insects used for biological control. After all the insects have been released, the controller 400 controls the insect release chamber 300 to close by receiving the signal from the third through-count sensor.

[0055] Specifically, the insect release chamber 300 is equipped with a third electric door 212, which is connected to the controller 400 for opening or closing the insect release chamber 300.

[0056] In this embodiment of the invention, the insect release device for biological control also includes a solar panel for powering the first electric gate 206 and the control device 207. That is, the solar panel provides energy for the electric drive of the insect release device for biological control to meet the needs of automatic outdoor insect release. Specifically, the solar panel is electrically connected to the first electric gate 206, the second electric gate 208, the third electric gate 212, the control device 207, and the drive motor.

[0057] See Figure 1 and Figure 2In this embodiment of the invention, the insect release device for biological control further includes a shell 213 forming a protective space, in which the pathogen attachment device 200 and the insect release chamber 300 are placed. That is, the shell 213 covers the outside of the adsorption material attachment chamber 204, the pathogen attachment chamber 201, and the insect release chamber 300, serving a waterproof function to prevent rainwater from entering the device, thereby maintaining a dry environment for the adsorption material attachment chamber 204, the pathogen attachment chamber 201, and the insect release chamber 300, and reducing the impact of the external environment on insect release.

[0058] Specifically, the inner wall of the outer shell 213 near the insect storage chamber 100 is provided with a third internal thread, and the side of the insect storage chamber 100 is provided with an external thread. The outer shell 213 and the insect storage chamber 100 are connected by threads. The end of the outer shell 213 near the insect release chamber 300 is provided with a through-hole. The through-hole passes through the insect release chamber 300 so that the insect can be released smoothly from the insect release chamber 300.

[0059] Specifically, the steps for using insect release equipment for biological control are as follows:

[0060] Step 1: Place the insects in the insect storage chamber 100 and install the outer shell 213;

[0061] Step 2: Preset the insect throughput at the first throughput sensor. After the number of insects entering the adsorption material attachment chamber 204 reaches the preset value, close the entrance of the adsorption material attachment chamber 204 by controlling the first electric door 206.

[0062] Step 3: Place adsorbent material in the adsorbent material storage chamber 205 above the adsorbent material attachment chamber 204, and drive the adsorbent material storage chamber 205 upside down so that the adsorbent material can pass through the first screen body 209 from the upper adsorbent material storage chamber 205 and attach to the insect's body surface. The unattached adsorbent material passes down through the first screen body 209 and falls into the lower adsorbent material storage chamber 205. Repeat the above process.

[0063] Step 4: Open the entrance to the pathogen attachment chamber 201 by controlling the second electric door 208 to open the entrance to the pathogen attachment chamber 201. After the number of insects passing through the second pass number sensor is equal to the number of insects passing through the first pass number sensor, or after no insects pass through within 15 minutes after the last insect passes through, control the second electric door 208 to close the entrance to the pathogen attachment chamber 201.

[0064] Step 5: Place the pathogens in the pathogen storage chamber 202 above the pathogen attachment chamber 201, and drive the pathogen storage chamber 202 upside down so that the pathogens can pass through the second screen body 210 from the upper pathogen storage chamber 202 and attach to the insect's body surface. The attached pathogens then pass down through the second screen body 210 and fall into the lower pathogen storage chamber 202. Repeat the above process.

[0065] Step Six: Open the insect release chamber 300 by controlling the third electric door 212 to release insects. When the number of insects passing through the third pass-through sensor is equal to the number passing through the second pass-through sensor, or when no insects pass through within 15 minutes after the last insect passes through, control the third electric door 212 to close the insect release chamber 300 to complete the insect release.
