Description

Technical Field

[0001] This invention relates to the field of mole rat population control, and more particularly to a system and method for interfering with the courtship and localization of plateau mole rats. Background Technology

[0002] The alpine meadows of the Qinghai-Tibet Plateau serve as a vital ecological security barrier for my country, playing an irreplaceable role in ecological services such as water conservation, windbreak and sand fixation, and biodiversity maintenance. However, in recent years, due to the impact of climate change and human activities, grassland degradation in this region has become increasingly severe, with statistics showing that the area of ​​degraded grassland has reached 5.0 × 10⁻⁶. 7 The sparse vegetation and loose soil resulting from grassland degradation have created an ideal habitat for underground rodents, leading to frequent rodent infestations. Among them, the plateau mole rat ( Eospalax baileyi (This is a major harmful rodent species. Due to its underground digging and bulldozing activities that damage vegetation, it has become a major harmful species threatening the ecological health of grasslands.)

[0003] The plateau mole rat lives in underground burrows, and its continuous digging and hill-building activities severely damage surface vegetation, creating large areas of barren "black soil beaches." This ecological degradation not only exacerbates soil erosion and reduces grassland productivity but also disrupts the original ecosystem balance, threatening regional ecological security. Currently, the control of the plateau mole rat mainly relies on chemical agents and biological toxins, employing a "population clearing" strategy. While such methods can reduce rodent density in the short term, long-term use will have multiple negative impacts on the ecosystem: on the one hand, non-targeted poisoning disrupts the food chain structure and affects the population of natural enemies; on the other hand, pesticide residues easily cause soil and water pollution, violating the concept of green ecological control. In addition, long-term chemical control will lead to drug resistance in the plateau mole rat and easily trigger a population rebound, making it difficult to achieve long-term control of the rodent infestation.

[0004] With increasing awareness of ecological and environmental protection, the concept of green and environmentally friendly pest control has gradually become an industry consensus. Behavioral intervention, as an emerging ecological regulation technology, controls population size by interfering with specific behaviors of pests, offering significant advantages such as high specificity, minimal ecological disturbance, and low susceptibility to resistance. Research has found that plateau mole rats exhibit solitary behavior during the non-courtship period, while during the courtship period, they use vibrational communication for mating and location. If precise behavioral interference technology can be developed based on their unique courtship mechanism to block information exchange and mating between males and females, population reproduction will be effectively suppressed, reducing population density at its source. Therefore, developing an eco-friendly plateau mole rat pest control method based on behavioral interference has significant theoretical and practical value for solving existing pest control challenges and protecting the ecological environment of the Qinghai-Tibet Plateau. Summary of the Invention

[0005] This invention provides a system and method for interfering with the courtship positioning of plateau mole rats. The system emits clear vibration waves to interfere with the courtship positioning between males and females during the courtship period, thereby reducing the reproduction rate and birth rate of plateau mole rats, and thus controlling their population density to achieve the purpose of prevention and control.

[0006] An interference method for the courtship positioning system of plateau mole rats includes: Multiple vibration signal acquisition devices are distributed in the target area. Each vibration signal acquisition device includes a high-sensitivity vibration sensor, signal preprocessing software, and a signal storage module. It is used to acquire vibration signals generated by male and female plateau mole rats during their courtship period, and to preprocess and store the signals. The specific vibration signal acquisition device is used to collect vibration signals generated by male and female plateau mole rats during their courtship period in the wild. This device employs a high-sensitivity vibration sensor, specifically an LGT-20D detector, with a natural frequency of 4.5±0.5 Hz, a sensitivity of 23.4±7.5% V / M / S, and a coil resistance of 395±5% kΩ. It can accurately capture the weak vibration signals produced by the plateau mole rats. The sensors are distributed in areas where plateau mole rats are frequently active, primarily near newly formed molehills.

[0007] The data analysis module, with built-in digital signal processing algorithms and data analysis software, is used to analyze the collected vibration signals and filter the characteristic parameters and time periods of vibration signals that interfere with the mating season's male and female mating location. The specific data analysis module analyzes and processes the collected vibration signals, filtering out characteristic parameters and time periods that interfere with the mating season's male-female courtship location. This module can employ advanced digital signal processing algorithms, such as Fast Fourier Transform (FFT), to convert the time-domain signal into a frequency-domain signal, thereby analyzing characteristic parameters such as the frequency and amplitude of the vibration signals. Simultaneously, by combining long-term monitoring data, the high-frequency time periods of the high-altitude mole rat's courtship season are determined.

[0008] Multiple percussion devices, each driven by a vibration generating mechanism, drive circuit, step-down module, and signal generating module, are used to further determine the effective transmission distance of the vibration signal of a single percussion device in the field. They are arranged in a dot matrix layout in the target area, i.e., in rows and columns. Through reasonable layout, convenience and efficiency are achieved, and one main control board can control multiple percussion devices to generate interference vibration waves. The percussion device can employ a push-pull electromagnet and damping pads. The push-pull electromagnet strikes through a magnetic attraction process, producing a crisp and clear signal, characterized by fast response and high control precision. Each percussion device can be controlled independently, and different vibration signals can be simulated by adjusting the chip program parameters.

[0009] The controller uses a time-sharing multi-threaded program to adjust the control program parameters based on the feature parameters and time periods selected by the data analysis module, thereby controlling multiple percussion devices to generate vibration waves. The specific control system improves CPU utilization to achieve synchronous response in the dot matrix distribution, thereby ensuring stable and efficient output signals and realizing synchronous control of multiple tappers. The controller can accurately control the tappers to generate interference vibration waves based on the characteristic parameters and time periods obtained from the data analysis module, thus interfering with the courtship positioning between male and female plateau mole rats over a large area.

[0010] The power module, including solar panels, batteries, and power management circuitry, provides power to the system.

[0011] The specific power modules provide a stable power supply for the entire system. The system is typically used in outdoor and even high-altitude environments, employing a combination of solar panels and batteries, along with a step-down module to convert 220V to 12V, ensuring normal operation under various weather conditions.

[0012] Furthermore, the multiple vibration signal acquisition devices are arranged according to the distribution pattern of male and female newborn mouse mounds, and the distance between adjacent devices is determined by the distance between the newborn mouse mounds.

[0013] Furthermore, the data analysis module also has data storage and historical data query functions.

[0014] Furthermore, the signal coverage areas of the adjacent tappers have an overlap of 0.5 to 1 meter.

[0015] Furthermore, the controller has timing control and manual control functions, and it interacts with the data analysis module through a communication interface.

[0016] A method for interfering with courtship localization in plateau mole rats includes the following steps: Vibration signals generated by male and female plateau mole rats during their courtship period were collected in the target area using a vibration signal acquisition device. Digital signal processing algorithms were then used to screen the characteristic parameters and time periods of vibration signals that interfered with the courtship location of male and female mole rats during the courtship period. Based on the selected characteristic parameters and time periods, the program parameters of the control device are adjusted, the effective transmission distance of the vibration signal generated by a single percussion device is determined in the field, and multiple percussion devices are controlled to generate interference vibration waves in a dot matrix layout to disrupt the courtship positioning between male and female plateau mole rats over a large area. After continuous interference for a certain period of time, the interference effect is evaluated through various assessment methods. Based on the evaluation results, the interference parameters are adjusted and the interference method is optimized.

[0017] Furthermore, the vibration signal characteristic parameters include the number of rounds per series, the time interval between adjacent rounds (s), the number of pulses per round, the time interval between adjacent pulses (s), and the daily generation time period of the vibration signal.

[0018] Furthermore, the assessment methods include the number of newborn mouse mounds, female pregnancy status, and changes in the weight of male reproductive organs.

[0019] Furthermore, the program parameter adjustment of the control device includes the number of rounds per series, the time interval between adjacent rounds (s), the number of pulses per round, and the time interval between adjacent pulses (s).

[0020] Adjacent pulse time interval: The time interval between two consecutive impacts of the snout and burrow wall by the plateau mole rat.

[0021] A single tapping round: The plateau mole rat generates multiple pulses by repeatedly striking the burrow wall with its snout, forming a pulse group, which constitutes a tapping round.

[0022] The number of taps per round refers to the number of pulses within a pulse group.

[0023] The single-round tap time (duration) refers to the total duration of a pulse group from the first pulse to the last pulse.

[0024] Adjacent round time interval: The time interval between the end of one pulse group and the start of the next pulse group.

[0025] Number of rounds in a single tap series: A complete signal consists of one or more pulse groups.

[0026] Total time for a single series: the cumulative time of the number of taps plus the cumulative time of the time interval between all adjacent taps.

[0027] Total duration of tapping rounds: The sum of the total duration of the pulse from the start to the end of each round.

[0028] Cumulative interval between adjacent rounds: the sum of the interval times between each round.

[0029] The present invention has the following advantages: This invention is based on the fact that plateau mole rats are solitary during the non-courtship period and use vibration signals to locate each other during the courtship period. By collecting vibration signals generated by male and female plateau mole rats during the courtship period in the wild, the characteristic parameters and time periods of vibration signals that interfere with the courtship location of male and female plateau mole rats were screened. Field vibration signal generation experiments were conducted to determine the effective transmission distance of the vibration signal of a single percussion device. The parameters were adjusted to control multiple percussion devices to generate vibration waves, which interfered with the courtship location of male and female plateau mole rats over a large area, affecting their mating and reproduction, reducing their reproductive success rate, and thus controlling the population density of plateau mole rats by affecting the population size of the next generation, ultimately achieving the goal of controlling the harm caused by plateau mole rats.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0032] Example 1: A system for interfering with courtship positioning in plateau mole rats, comprising: Multiple vibration signal acquisition devices are distributed in the target area. Each vibration signal acquisition device includes a high-sensitivity vibration sensor, signal preprocessing software, and a signal storage module. It is used to acquire vibration signals generated by male and female plateau mole rats during their courtship period, and to preprocess and transmit the signals. Collection of courtship vibration signals within the target area: First, based on the number of new molehills produced by plateau mole rats in the grassland, a self-developed non-destructive live capture technique for mole rats, combined with radio tracking technology, is used to determine the activity range of male and female plateau mole rats and the distribution pattern of new molehills. During the courtship period, courtship vibration signals are collected within the target area based on the direction of new molehills produced by males and females and the results of radio tracking. For example, in a grassland area where plateau mole rats are distributed on the Qinghai-Tibet Plateau, an area far away from residential areas and roads is selected as the target area for vibration signal collection. During the courtship period, courtship vibration signals produced by males and females are collected based on the direction of new molehills produced by males and females and the results of radio tracking.

[0033] Device setup and implementation: Based on the orientation of newly formed mouse mounds during the mating season, vibration signal acquisition devices are arranged around the newborn mouse mounds. For male mice, the vibration signal acquisition devices are arranged in a straight line around the newborn mouse mounds along their orientation; for female mice, the vibration signal acquisition devices are arranged in a ring around the main nest, along the orientation of the newborn mouse mounds.

[0034] Sensor and circuit installation: The vibration signal acquisition sensor is a high-sensitivity LGT-20D detector with a natural frequency of 4.5±0.5 Hz, a sensitivity of 23.4±7.5% V / M / S, and a coil resistance of 395±5% kΩ, and is connected to a signal conditioning circuit. The filtering parameters and amplification factor of the signal conditioning circuit are preset and adjusted according to the frequency and intensity characteristics of the vibration signal from the plateau mole rat to ensure effective processing of the acquired signal.

[0035] Signal preprocessing: The vibration wave signals collected by each acquisition device undergo noise reduction processing. When the plateau mole rat generates a vibration signal, the high-sensitivity vibration sensor transmits the signal to the signal conditioning circuit. After noise reduction, filtering, and amplification, the signal is sent by the transmission module to the data analysis module, which stores and analyzes the received signal.

[0036] The data analysis module uses a high-performance data processing chip and has built-in digital signal processing algorithms and data analysis software to analyze the collected vibration signals, screen the characteristic parameters and time periods of vibration signals that interfere with the mating season and determine the effective transmission distance of vibration signals generated by a single percussion instrument through field experiments. The data analysis module uses TI's TMS320C6748 data processing chip and runs data analysis software developed based on MATLAB. Figure 4During the mating season of the plateau mole rat (April-May), the collected vibration signals were analyzed. It was determined that the frequency of the mating vibration signals was concentrated in the low frequency range, with the daily peak mating periods being 7:00-10:00, 15:00-23:00, and 24:00-03:00. The plateau mole rats did not produce seismic signals during the time periods of 11:00-14:00 and 4:00-6:00, during which signal interference could be avoided. The effective transmission distance of a single tapper was 2.5 meters.

[0037] Multiple percussion devices, each consisting of a push-pull electromagnet and a shock-absorbing pad, are arranged in a dot matrix pattern, i.e., in rows and columns, in the target area to generate interfering vibration waves. The controller and control system employs a microprocessor chip and a time-sharing multi-threaded program. Based on the characteristic parameters and time periods selected by the data analysis module, the control program parameters are adjusted to control multiple percussion devices to generate vibration waves. The power module, including solar panels, batteries, and power management circuitry, provides power to the system.

[0038] Specifically, the multiple vibration signal acquisition devices are arranged according to the orientation of the newborn mouse mounds, and the spacing between adjacent devices is determined according to the distance between the newborn mouse mounds.

[0039] Specifically, the data analysis module also has data storage and historical data query functions.

[0040] Specifically, the signal coverage areas of the adjacent tappers have an overlap of 0.5-1 meter.

[0041] Specifically, the controller has timed control and manual control functions, and interacts with the data analysis module through a communication interface.

[0042] Example 2, a method for interfering with courtship localization in plateau mole rats, comprising the following steps: Vibration signals generated during the mating season of male and female plateau mole rats were collected in the target area using a vibration signal acquisition device. Digital signal processing algorithms were used to screen the characteristic parameters and time periods of vibration signals that interfere with the mating location of male and female rats during the mating season. The effective transmission distance of the vibration signal of a single tapper was determined through field launch experiments. Based on the selected characteristic parameters and time periods, the program parameters of the control device are adjusted to control multiple tappers to be distributed in a dot matrix pattern, i.e., arranged in rows and columns. Through reasonable layout, convenience and efficiency are achieved, and one main control board controls multiple tappers to generate interference vibration waves, which can cause large-scale interference with the courtship positioning between male and female plateau mole rats. After continuous interference for a certain period of time, the interference effect is evaluated through various assessment methods. Based on the evaluation results, the interference parameters are adjusted and the interference method is optimized.

[0043] Specifically, the vibration signal characteristic parameters include the number of rounds per series, the time interval between adjacent rounds (s), the number of pulses per round, the time interval between adjacent pulses (s), and the daily generation time period of the vibration signal.

[0044] Specifically, the assessment methods include the number of newborn mouse mounds, female pregnancy status, and changes in the weight of male reproductive organs.

[0045] Specifically, the program parameter adjustment of the control device includes the number of rounds per series, the time interval between adjacent rounds (s), the number of pulses per round, and the time interval between adjacent pulses (s).

[0046] See Figure 1 , Figure 1 A flowchart illustrating the courtship and localization methods of the plateau mole rat is presented: Individual capture and tracking: Undamaged live plateau mole rats were obtained, and radio transmitters were attached to the captured individuals before release. In the wild, the plateau mole rats with transmitters were tracked and located using radio receivers and antennas to obtain their activity trajectory information in real time. Based on the obtained activity trajectory, the distribution characteristics of the plateau mole rats' nesting areas and the direction of their burrows were analyzed.

[0047] Courtship vibration signal acquisition and analysis: Based on the distribution pattern of new mouse mounds where "male mice form a line and female mice swirl around," courtship vibration signals were collected along the straight line formed by the newly formed mouse mounds of male mice; for female mice, courtship vibration signals were collected in the area surrounding their newly formed mouse mounds; the collected courtship vibration signals from both sexes were analyzed and processed to determine the characteristic parameters of the courtship vibration signals of the plateau mole rat, and the specific time period of interference vibration signal action was determined in conjunction with the courtship habits of the plateau mole rat.

[0048] Interference distance determination: The percussion device is used as a vibration signal transmitter. Signal acquisition devices are arranged at 1-meter intervals around the percussion device to test the farthest distance that the vibration wave generated by a single percussion device can effectively transmit, thereby determining the effective transmission distance of a single percussion device.

[0049] Large-area interference: Based on the effective transmission distance of a single tapper, tappers are deployed over a large area in the activity area of ​​the plateau mole rat in a dot matrix layout; during the specific time period of the determined interference vibration signal, the tappers are activated to emit interference vibration signals, thereby achieving large-area interference with the mating location of male and female plateau mole rats.

[0050] Evaluation of effectiveness: Adult plateau mole rats were captured at the end of their courtship period. Pregnancy rates were measured in females and the weight of reproductive organs was measured in males. The effectiveness of plateau mole rat pest control was evaluated by analyzing changes in female pregnancy rates and male reproductive organ weight.

[0051] See Figure 3 , Figure 3 The document describes the number of rounds in a single courtship vibration signal series, ranging from 1 to 24 rounds; the time interval between two adjacent courtship vibration signal rounds, ranging from 0.470 to 6.74 seconds; the number of pulses in each courtship vibration signal round, ranging from 2 to 19 pulses; and the time interval between two adjacent pulses, ranging from 0.052 to 0.301 seconds.

[0052] Interference Implementation and Effect Evaluation Based on preliminary research and surveys, a region far from residential areas and roads was selected as the target area for vibration signal collection in a grassland area where plateau mole rats are distributed on the Qinghai-Tibet Plateau. Live, undamaged plateau mole rats were obtained from the target area. After the captured individuals were fitted with radio transmitters, they were released back into the wild. The plateau mole rats with transmitters were tracked and located in the target area using radio receivers and antennas to obtain their activity trajectory information in real time. Based on the obtained activity trajectory, the distribution characteristics of the plateau mole rats' nesting areas and the direction of their burrows were analyzed.

[0053] As a vibration signal transmitting device, the percussion instrument is used as the center. Signal acquisition devices are arranged at 1-meter intervals around the percussion instrument to test the farthest distance that the vibration wave generated by a single percussion instrument can be effectively transmitted, thereby determining the effective transmission distance of a single percussion instrument. The effective transmission distance of the vibration signal of a single percussion instrument was measured to be 2.5 meters.

[0054] Based on the orientation of newborn mouse mounds in males and females, the spacing between newborn mounds, and radio tracking results, vibration signal acquisition devices and knockers were deployed within the target area. For male mice, vibration signal acquisition devices were arranged in a straight line around the newborn mounds, following their orientation. For female mice, vibration signal acquisition devices were arranged in a ring around the main nest, following the orientation of the newborn mounds. The knockers were deployed in a dot-matrix pattern, i.e., in rows and columns, within the target area. A total of 320 knockers were ultimately deployed to generate interference vibration waves, disrupting the courtship positioning between males and females during the mating season. Figure 2 As shown; The collected courtship vibration signals from male and female mole rats were analyzed and processed to determine the characteristic parameters of the courtship vibration signals of plateau mole rats. Based on the courtship habits of plateau mole rats, the specific time period of the interference vibration signal was determined.

[0055] Based on the selected characteristic parameters and time periods, and combined with the effective response range of the control device, the chip program parameters of the control device are adjusted, such as... Figure 5 As shown, the vibration signal is generated in an infinite loop, with a fixed time interval of 0.474 seconds between two adjacent vibration signal rounds; each vibration signal round contains 22 pulses, with a time interval of 0.083 seconds between two adjacent pulses. The control device controls the percussion device to generate interference vibration wave signals according to the above parameters to disrupt the courtship positioning between male and female plateau mole rats.

[0056] See Figure 4 , Figure 4 The diurnal time periods during which vibration signals are generated during the breeding season of the plateau mole rat are described, including the signal generation period and the non-signal generation period.

[0057] Signal generation periods: During the peak breeding season of the plateau mole rat, the vibration signals are generated during the following specific time periods: 7:00-10:00, 15:00-23:00, and 24:00-3:00. Non-signal generation periods: During the periods of 11:00-14:00 and 4:00-6:00 daily, the plateau mole rat does not generate vibration signals.

[0058] Based on the aforementioned vibration signal generation patterns, during the courtship period of the plateau mole rat, a control device is activated during the high-frequency periods of vibration signal generation (i.e., 7:00-10:00, 15:00-23:00, and 24:00-3:00). This control device controls multiple percussion devices to generate interference vibration waves according to preset interference vibration signal characteristic parameters (including the number of rounds, round time intervals, number of pulses per round, and pulse time intervals). During non-signal generation periods (i.e., 11:00-14:00 and 4:00-6:00), the control device does not activate the percussion devices and does not emit interference vibration waves. Figure 4 The peak breeding season for plateau mole rats generates seismic signals during the periods of 7:00-10:00, 15:00-23:00, and 24:00-3:00. During the high-frequency periods of the plateau mole rats' courtship period, a control device is activated to control multiple percussion devices to generate interference vibration waves according to preset parameters. Plateau mole rats do not generate seismic signals during the periods of 11:00-14:00 and 4:00-6:00, and signal interference can be avoided during these periods. After 42 days of continuous disturbance, plateau mole rats were captured live in both the experimental and control areas, and the corresponding population sizes in the two plots were calculated. Simultaneously, the captured female plateau mole rats were dissected, and their pregnancy rates were determined.

[0059] See Figure 6, Figure 6 This paper presents schematic diagrams of female uteri in control and experimental plots after interfering with courtship positioning between male and female plateau mole rats. The red boxes in the diagrams show pregnant uteri, and the third red box from the left in both the control and experimental plots shows fetal images.

[0060] See Figure 7 , Figure 7 This diagram illustrates the pregnancy rates of females in the control and experimental plots after interfering with courtship location techniques between male and female plateau mole rats. With the same population density in both plots, 8 out of 10 adult individuals became pregnant in the control area, while only 3 out of 10 adult individuals became pregnant in the experimental area. Compared to the control area, the pregnancy rate decreased by 50% after interfering with courtship location techniques.

[0061] Based on the fact that plateau mole rats are solitary during the non-courtship period and use vibration signals for courtship location during the courtship period, this study collected vibration signals generated by male and female plateau mole rats during the courtship period in the wild. Characteristic parameters and time periods of these vibration signals that interfere with courtship location were then selected. Field vibration signal generation experiments determined the effective transmission distance of a single vibrator. Adjusting parameters allowed for the control of multiple vibrators to generate vibration waves, thus significantly interfering with courtship location between male and female plateau mole rats, affecting their mating and reproduction, and reducing their reproductive success rate. By influencing the population size of the next generation, this study aims to regulate the plateau mole rat population density and ultimately achieve the goal of controlling the harm caused by plateau mole rats.

[0062] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
