Description

Technical Field

[0001] This invention relates to the field of pest and disease management technology, and in particular to a method and system for cyclic low-pressure stimulation to induce and kill aphids. Background Technology

[0002] Aphids are a very common pest in cotton production. They cause direct damage by sucking sap from the phloem of plants and can transmit various plant viruses, leading to a severe decline in crop yield and quality. Statistics show that aphid damage can cause crop losses of 15% to 30% annually, and in severe cases, even total crop failure. Currently, aphid control mainly relies on chemical pesticides. However, the long-term and large-scale use of chemical pesticides has led to a series of serious ecological, environmental, and food safety problems, including pesticide residues, environmental pollution, killing of natural enemies, and increased pesticide resistance in aphids. Therefore, finding efficient, safe, and environmentally friendly new technologies for aphid control has become a critical issue that urgently needs to be addressed in this field.

[0003] In recent years, physical control methods have received widespread attention due to their advantages such as being pollution-free and residue-free. For example, using high-voltage electrostatic technology to control pests is considered a promising new approach. Existing technologies also include some solutions for controlling cotton aphids using high-voltage electrostatics. However, similar electrostatic insecticidal technologies rely primarily on prolonged high-voltage electrostatic field radiation, often requiring long treatment times (e.g., several hours) to achieve the desired eradication effect. This results in low efficiency in field operations and makes it difficult to meet the practical needs of large-scale, rapid pest control in agriculture.

[0004] Therefore, there is an urgent need in this field to develop a new insecticidal solution that can quickly and efficiently kill aphids. Summary of the Invention

[0005] This invention provides a method and system for cyclic low-pressure stimulation to kill aphids, which solves the problem of low efficiency in electrostatic aphid killing in related technologies. In this application, the efficiency of aphid killing can be accelerated by airflow guidance, and cyclic low-pressure stimulation is applied before high-pressure killing to force aphids to migrate, further improving the efficiency of aphid killing.

[0006] This invention provides a system for cyclic low-pressure stimulation-induced aphid killing, comprising: The low-pressure stimulation induction module includes a gate-shaped induction frame, which is used to induce aphids to migrate by applying cyclic low-pressure stimulation as they pass through cotton plants. An airflow guiding module includes an air blowing end and an air extraction end, which are located at both ends of the gate-shaped induction net to generate airflow and guide aphids to move to the air extraction end. The high-pressure killing module is located at the air extraction end of the airflow guiding module and is used to kill aphids by high pressure.

[0007] According to the cyclic low-pressure stimulation-induced aphid killing system provided by the present invention, the gull-shaped induction frame includes a first induction net, a second induction net, and a third induction net; The first induction net is disposed at the top of the portal induction frame to generate a constant low-voltage electric field; The second and third induction nets are respectively disposed on both sides of the portal frame to generate a low-voltage electric field in a cyclic manner.

[0008] According to the cyclic low-pressure stimulation-induced aphid killing system provided by the present invention, the low-pressure electric fields generated by the second induction net and the third induction net alternate.

[0009] According to the cyclic low-pressure stimulation-induced aphid killing system provided by the present invention, the low-pressure stimulation-induced module further includes a low-pressure electrostatic generator, which is electrically connected to the first induction net, the second induction net and the third induction net, and is used to supply power to the first induction net, the second induction net and the third induction net.

[0010] The system for cyclic low-pressure stimulation-induced aphid killing provided by the present invention further includes a high-pressure electrostatic generator and a high-pressure killing net in the high-pressure killing module. The high-voltage electrostatic generator is electrically connected to the high-voltage extinguishing network and is used to supply power to the high-voltage extinguishing network. The high-pressure killing net is used to kill aphids that pass through it using high pressure.

[0011] According to the cyclic low-pressure stimulation-induced aphid killing system provided by the present invention, the airflow guiding module further includes an air blowing pump and an air extraction pump. The blowing air pump is connected to the blowing end, and the suction air pump is connected to the suction end.

[0012] The system for cyclic low-pressure stimulation-induced aphid killing provided by the present invention also includes a shielding net; The shielding mesh is used to isolate the high-voltage extinguishing mesh from the gantry-shaped induction frame.

[0013] This invention also provides a method for inducing and killing aphids using cyclic low-pressure stimulation, and a system for inducing and killing aphids using cyclic low-pressure stimulation includes: Receive start signal; Upon triggering by the activation signal, the low-pressure stimulation induction module generates cyclic low-pressure pulses, which are used to stimulate aphids to migrate. Upon triggering of the activation signal, the airflow guiding module generates airflow to guide the migrating aphids; When triggered by the start signal, the high-voltage killing module generates a high-voltage pulse to kill the aphids that pass by.

[0014] According to the method for inducing aphid killing by cyclic low-pressure stimulation provided by the present invention, the low-pressure stimulation induction module generates cyclic low-pressure pulses, including: The low-pressure stimulation induction module applies pulses according to a preset pulse intensity and adjusts the pulse intensity according to a preset period.

[0015] The cyclic low-pressure stimulation-induced aphid-killing system provided by this invention uses a low-pressure stimulation induction module to first induce low-pressure stimulation in aphids, forcing them to migrate on cotton plants. During the migration, some of the aphids' legs will temporarily detach from the cotton plants, weakening the adhesion between them. At this point, an airflow guiding module can guide the aphids to completely detach from the cotton plants and move them with the airflow to the high-pressure killing module. The high-pressure killing module can then kill the aphids with high pressure. During this process, the low-pressure stimulation generated by the low-pressure stimulation induction module can be cyclically varied to avoid the electric field gradually attenuating due to the obstruction of cotton plant leaves and the distance, thus affecting the killing effect.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0020] like Figure 1 and Figure 2 As shown, this embodiment provides a system for cyclic low-pressure stimulation-induced aphid killing, including: The low-pressure stimulation induction module includes a gate-shaped induction frame 1, which is used to induce aphids to migrate by applying cyclic low-pressure stimulation when passing through cotton plants. An airflow guiding module includes an air blowing end 2 and an air extraction end 3, which are located at both ends of the gate-shaped induction net to generate airflow and guide aphids to move to the air extraction end. The high-pressure killing module is located at the air extraction end of the airflow guiding module and is used to kill aphids by high pressure.

[0021] In practical applications, the gate-shaped guiding frame includes a first guiding net 4, a second guiding net, and a third guiding net; The first induction net 4 is disposed on the top of the portal induction frame to generate a constant low-voltage electric field; The second and third induction nets are respectively disposed on both sides of the gate-shaped induction frame 1 to generate a low-voltage electric field in a cyclic manner. For example, the cycle period can be 2 seconds, and the electric field strength can fluctuate between 2.5kV / m and 3.5kV / m in each cycle.

[0022] The reason why the first induction net does not generate a cyclic low-voltage electric field is to avoid the vacuum period of insecticidal effect caused by the first, second and third induction nets being in a low-voltage state at the same time. On the other hand, cotton aphids usually hide on the back of the leaves. In this embodiment, controlling the first induction net to always output a strong low-voltage electric field can also improve the stimulation efficiency for aphids on the back of the leaves and reduce the impact of the electric field attenuation caused by the impedance of the leaves.

[0023] like Figure 1 As shown, Figure 1 The example illustrates the setup of the first guiding net 4. In practical applications, the first guiding net 4 can also be set up in other layouts, such as Z-shaped, horizontally tiled, or vertically tiled.

[0024] Figure 2The example illustrates the placement of the second and third guide nets, which are respectively placed on both sides of the gate-shaped guide frame 1. The placement of the second and third guide nets can be the same as that of the first guide net 4. For example, they can be set in a Z-shape, horizontally laid out, or vertically laid out.

[0025] In practical applications, the second and third induction nets can cyclically generate a low-voltage electric field. Specifically, this device constructs a uniformly covered cyclic pulsed low-voltage electric field within the channel cross-section by symmetrically arranging the second and third induction nets on both sides of the portal frame, achieving continuous physical control of aphids. Compared to a static pulsed electric field, the core advantage of this cyclic pulse mode lies in its periodic energy output mechanism. At the biological resistance level, the variable frequency and interval output characteristics of the cyclic pulse constitute unpredictable non-steady-state electrophysiological interference to aphids. On the one hand, it continuously disrupts the conduction of nerves in their antennae, destroys the establishment of habitual reflexes, and prevents them from avoiding the electric field area through behavioral regulation. On the other hand, the intermittent high-energy micro-electroporation effect repeatedly damages the cell membrane structure, and the repair cycle is forcibly interrupted by the next round of pulses, resulting in continuous cell dysfunction. This strategy, which applies pressure through both neural transmission and cell repair pathways, makes it difficult for aphids to develop tolerance at both the behavioral adaptation and physiological metabolism levels. This ensures the stable maintenance of control effects during long-term use, providing a low-energy, high-efficiency, and degradation-resistant physical pest control solution for the agricultural plant protection field.

[0026] For example, the second and third decoy networks In an exemplary embodiment, the low-voltage stimulation induction module further includes a low-voltage electrostatic generator 5, which is electrically connected to the first induction net 4, the second induction net, and the third induction net, and is used to supply power to the first induction net 4, the second induction net, and the third induction net.

[0027] In an exemplary embodiment, the high-voltage sterilization module further includes a high-voltage electrostatic generator 6 and a high-voltage sterilization net 7; The high-voltage electrostatic generator 6 is electrically connected to the high-voltage extinguishing net 7 and is used to supply power to the high-voltage extinguishing net 7. The high-pressure killing net 7 is used to kill aphids by high pressure as they pass by. The high-pressure killing net can be set inside the gate-shaped induction frame.

[0028] In an exemplary embodiment, the airflow guiding module further includes a blowing air pump and a suction air pump; The blowing air pump is connected to the blowing end, and the suction air pump is connected to the suction end.

[0029] In an exemplary embodiment, a shielding mesh 8 is also included; The shielding net is used to isolate the high-pressure extinguishing net from the gate-shaped induction frame, so as to prevent the high pressure of the high-pressure extinguishing net from affecting the plants passing through the gate-shaped induction frame.

The method for killing aphids by cyclic low-pressure stimulation described below can be referred to in correspondence with the system for killing aphids by cyclic low-pressure stimulation described above.

Step 303: Upon triggering by the start signal, the airflow guiding module generates airflow to guide the migrating aphids. Step 304: Upon triggering by the start signal, the high-voltage killing module generates a high-voltage pulse to kill the passing aphids.

[0032] The specific implementation method of the cyclic low-pressure stimulation-induced aphid killing method provided in this embodiment can be carried out with reference to the above embodiment, and will not be repeated here.
