Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of biological control, in particular to a method for evaluating the field colonization ability of natural enemy insects based on harmonic radar technology. BACKGROUND

[0002] In biological control, the field colonization ability of natural enemy insects is a key indicator for evaluating their control effect.

[0003] Traditional evaluation methods, such as direct observation method and release and recovery method, have many limitations.

[0004] The direct observation method is limited by the visual range and observation time of humans, and it is difficult to fully grasp the activity of natural enemy insects in the field;

[0005] The release and recovery method has low recovery rate, and may cause harm to natural enemy insects during the recovery process, affecting their subsequent survival and reproduction, resulting in inaccurate evaluation results.

[0006] Therefore, a more accurate and efficient evaluation method is needed to accurately judge the field colonization ability of natural enemy insects. SUMMARY

[0007] The purpose of the present application is to provide a method for evaluating the field colonization ability of natural enemy insects based on harmonic radar technology, by marking natural enemy insects and using harmonic radar technology to realize real-time and dynamic monitoring of their activities in the field, so as to more accurately evaluate their colonization ability and solve the technical problems raised in the background art.

[0025] so as to ensure the effectiveness of subsequent monitoring.

[0026] Further, the S3 at least includes the following steps:

[0027] According to the actual situation in the field, a layout design is made;

[0028] According to the layout design, a harmonic radar monitoring device is used to ensure that the device can cover the entire target monitoring area when in use, avoid signal interference, and ensure the comprehensiveness and accuracy of the monitoring.

[0029] Further, the basis of the layout design includes at least the monitoring area size, the terrain undulating condition and the crop category distribution, thereby realizing all-around and dead-angle-free monitoring of the target area.

[0030] Further, the S4 at least includes the following steps:

[0031] starting the harmonic radar monitoring device, so that the harmonic radar monitoring device continuously emits the fundamental wave signal;

[0032] When the harmonic radar sensing tag on the natural enemy insect receives the fundamental wave signal, a harmonic wave signal is fed back to the monitoring device;

[0033] The monitoring device receives and processes the feedback harmonic wave signal in real time, and accurately records key data, wherein the key data at least includes the position, the moving direction and the residence time of the natural enemy insect, and the position, the moving direction and the residence time of the natural enemy insect are used to analyze the distribution frequency, the settlement point, the diffusion range and the preference of different crop areas of the natural enemy insect in the field;

[0034] The data collection process needs to be continuously carried out to obtain sufficient and comprehensive data samples to support subsequent accurate analysis.

[0035] Further, the S5 at least includes the following steps:

[0036] After the data collection of S4, professional data analysis methods and tools are used to deeply analyze the recorded data in the collected information;

[0037] Through comprehensive consideration and evaluation of the data, hidden insect behavior patterns and colonization characteristics are obtained, wherein the colonization characteristics are the colonization ability evaluation results of the natural enemy insect in the field area, and provide a scientific basis for the development and optimization of biological control strategies.
