Description

Technical Field

[0001] The present invention relates to the technical field of pest control, and in particular to a control method, device and equipment for intercepting and eradicating red imported fire ants in newly-infested areas. Background Art

[0002] The red fire ant Solenopsis invicta Buren (RIFA) is one of the most dangerous invasive species in the world. The invasion of red fire ants presents a trend of population explosion, huge numbers, rapid spread, and attack damage. The invasion of red fire ants can easily cause losses in agriculture, forestry, animal husbandry and fishery, destroy the ecological environment, and threaten human health and biodiversity.

[0003] Biological invasion is a common problem facing the world and an urgent problem that needs to be solved. By the end of 2023, red fire ant epidemics occurred in 625 county-level administrative regions in 12 provinces (cities and regions) across the country. According to incomplete statistics, alien invasive organisms cause more than 200 billion yuan in losses to my country's agriculture, forestry, ecological environment, etc. each year. The agricultural and rural departments have also formulated a series of management policies and technical programs and carried out a lot of prevention and control work. However, due to the increase in the transportation of commodities such as seedlings with soil, turf, and building materials, and the light and temperature conditions in South my country are particularly suitable for their survival and reproduction, red fire ants can still spread rapidly in my country. The overall red fire ant epidemic is spreading rapidly, the epidemic is severe, and the local damage is severe. In recent years, the trend of the occurrence and spread of the red fire ant epidemic has intensified, seriously affecting the safety of local crop production, the safety of the ecological environment, and the health of citizens.

[0004] In order to fully intercept and control the spread of red fire ants, achieve sustainable agricultural development, and protect agricultural production, the ecological environment, and the safety of people's lives, my country's red fire ant prevention and control technical measures have been gradually improved. However, at present, red fire ant monitoring and prevention and control are mainly manual, and the prevention and control methods are unscientific. Ordinary contact pesticides are generally used to prevent and control red fire ants, and nests are randomly filled, and baits are spread in ant nests. The prevention and control methods are unscientific, and the eradication and control work is not in place, causing the red fire ants in the nests to escape, split, and spread, making it difficult to achieve a good prevention and control effect. Therefore, it is urgent to accelerate the prevention and control methods and applications of red fire ants in newly-infested areas, and the existing technologies need to be improved and developed.

The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" or "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0021] See also Figure 1 , Figure 1 A flow chart of a control method for intercepting and eradicating red imported fire ants in newly-infested areas provided by the present invention is shown in the figure, which comprises the following steps:

[0022] S10. When a red fire ant outbreak is discovered, new outbreak areas and potential outbreak areas are identified, and the new outbreak areas are sealed off;

[0023] In this embodiment, the newly-incidence area refers to the area where the red fire ant outbreak occurs for the first time or the area where the outbreak point is relatively independent; the potential outbreak area refers to the area within 500m extending outward from the newly-incidence area. The steps of blocking the newly-incidence area include: strictly controlling the external logistics of the newly-incidence area of ​​the red fire ant outbreak to prevent the spread of the red fire ants; prohibiting the transportation of garbage, waste soil, construction mud, and compost in the newly-incidence area, and strictly quarantine seedlings, flowers, bonsai, and turf with soil. Through blockade control, this embodiment can effectively curb the further spread of the red fire ant outbreak, protect surrounding areas from the invasion of red fire ants, concentrate resources and forces to block and deal with the epidemic area, improve the efficiency and effectiveness of prevention and control work, and reduce the cost of prevention and control.

[0024] S20. Conduct monitoring and investigation on the newly-incidence areas and potential outbreak areas to obtain the distribution range and occurrence extent of red fire ants;

[0025] In this embodiment, firstly, the ant nest picture and location information uploaded by the staff are obtained; then, the neural network model is used to automatically identify whether the ant nest picture is a red fire ant nest; when it is determined to be a red fire ant nest, a dynamic map of the red fire ant occurrence area is generated in combination with the location information; according to the distribution density and diffusion trend of the red fire ants displayed in the dynamic map of the red fire ant occurrence area, the red fire ant occurrence area is divided into risk areas of different levels.

[0026] Specifically, first collect a large number of pictures of red fire ant nests and pictures of non-red fire ant nests for comparison. These pictures can come from different environments, such as farmland, grassland, park, etc.; mark each picture, clearly mark which are red fire ant nests and which are not, and the marking work can be completed by professional image marking software to ensure the accuracy and consistency of the marking; then select a neural network model suitable for the target detection task, such as YOLOv5, Faster R-CNN, etc. These models perform well in the field of target detection and can accurately identify and locate the target in the picture; use the labeled data set to train the model. During the training process, the model will learn the characteristics of the red fire ant nest, including shape, color, texture, etc., so as to accurately identify it in subsequent pictures; deploy the trained neural network model to the actual application scenario, use the deployed model to identify the real-time collected pictures, and quickly determine whether there is a red fire ant nest in the picture. In this embodiment, the pictures obtained by the camera and other equipment can cover a wider area, improve the coverage and efficiency of monitoring, and the automatic recognition system of the neural network model can replace manual inspection, saving a lot of manpower and material resources.

[0027] In this embodiment, the location information of the red fire ant nest is sorted into red fire ant point data in chronological order; in the GIS software, the map of the destination area is first loaded, and then the red fire ant point data of each day are marked on the map respectively; using the timeline function of the GIS software, the red fire ant point data at different time points are superimposed on the map to form a dynamic map of the red fire ant occurrence area points.

[0028] Specifically, the "cloud collection" system or other similar digital tools can be used to collect the location information of red fire ant nests in real time, which includes detailed data such as the longitude and latitude coordinates of each nest, the time of discovery, and the size of the nest. The public, professional prevention and control personnel, and managers can also be encouraged to report the location information of red fire ant nests through mobile applications (such as mini-programs) to ensure the comprehensiveness and real-time nature of the data. The collected location information of red fire ant nests can then be imported into GIS (geographic information system) or related data processing software to clean and organize the data, remove duplicate or invalid information, and ensure the accuracy and reliability of the data. In the GIS software, the location of each nest is marked on the map according to the longitude and latitude coordinates of the red fire ant nest. Different colors or icons can be used to represent different levels of red fire ant epidemic areas, such as severe outbreak areas, moderate outbreak areas, and mild outbreak areas. The dynamic graph function of the GIS software can be used to visualize the changes in the location information of red fire ant nests over time. A timeline can be set to show the changes in the red fire ant outbreak areas in different time periods to form a dynamic point map. This embodiment combines the location information of red fire ant nests to generate a dynamic map of the red fire ant occurrence area, which is an efficient and scientific prevention and control method. It is of great significance for timely grasping the epidemic situation, improving prevention and control efficiency, assisting decision-making, and enhancing public awareness.

[0029] In this embodiment, key data such as the occurrence point, number, distribution density and diffusion trend of red fire ants are extracted from the dynamic map, and these data are deeply analyzed to identify the high-incidence areas, diffusion paths and potential transmission risk points of red fire ants. According to the occurrence degree, distribution density and diffusion speed of red fire ants, a scientific risk level classification standard is formulated. For example, the red fire ant occurrence degree classification standard in the "Provincial Red Fire Ant Monitoring and Prevention Technical Plan" can be referred to and adjusted in combination with actual conditions. The standard may include but is not limited to factors such as the number of ant nests per unit area, the number of worker ants, and the speed of epidemic spread. According to the formulated classification standards, the red fire ant occurrence area is divided into risk areas of different levels. For example, it can be divided into low-risk areas, medium-risk areas and high-risk areas, and the boundaries and positions of each risk area are clearly marked on the map to form an intuitive risk distribution map. In this embodiment, the risk area is divided according to the distribution density and diffusion trend of red fire ants displayed in the dynamic map of the red fire ant occurrence area, which is a scientific and effective prevention and control method; by accurately dividing the levels and taking corresponding prevention and control measures, the spread and harm of the red fire ant epidemic can be effectively controlled.

[0030] S30, according to the distribution range and occurrence degree of the red fire ants, killing and preventing the red fire ants in their nests in stages to curb the occurrence and spread of the red fire ants;

[0031] In this embodiment, the areas where red fire ants occur are divided into high-risk areas, medium-risk areas and low-risk areas; for high-risk areas, highly efficient and low-toxic baits, powders or liquid medicines are selected, and a combination of spot application, broadcast application and nest filling is adopted to ensure that the medicine covers all the activity areas of red fire ants, and the medicine is applied at least once a month; for medium-risk areas, chemical medicines are mainly used, supplemented by biological control agents, and the medicine is mainly applied by broadcasting and spot application. The red fire ant nests and activity areas in the medium-risk areas are applied, and the medicine is applied at least once a quarter; for low-risk areas, regular inspections are carried out, mainly by spot application, and the medicine is applied to the red fire ant nests found. This embodiment applies different drug application strengths to different levels of risk areas to kill red fire ants. It is necessary to formulate a scientific and systematic prevention and control plan, and flexibly adjust it in combination with actual conditions. By strengthening monitoring, scientific drug application, ecological restoration and other comprehensive measures, the spread and harm of red fire ants can be effectively controlled.

[0032] S40. Conduct prevention effectiveness investigation and follow-up monitoring on the red fire ant nests after they have been killed, and guide the next step of prevention and control based on the monitoring results.

[0033] In this embodiment, when the control effect reaches 100% eradication, monitoring will be carried out from the current month, and then continuously every month thereafter; when red fire ants are monitored, baits will be spread again to continue to kill them, and the pesticides will be applied repeatedly to ensure that the new outbreak area maintains a 100% eradication effect for 6-12 consecutive months. Through the prevention effect investigation and tracking monitoring, this embodiment can timely discover the activity and distribution range of red fire ants, and provide accurate data support for prevention and control work. This helps to improve the efficiency of prevention and control and reduce the cost of prevention and control; optimizing the prevention and control plan based on the monitoring results can reasonably allocate prevention and control resources to avoid waste of resources and repeated investment. At the same time, it can also ensure the scientificity and effectiveness of prevention and control measures.

[0034] The present invention will be further explained below by means of specific embodiments:

[0035] In April 2021, the interception and eradication of red fire ants in newly-incidence areas was carried out in ZS Town. First, the newly-incidence areas and potential outbreak areas were identified and blocked off. Secondly, monitoring surveys were conducted in the newly-incidence areas and potential outbreak areas in ZS Town before and after prevention and control. According to the local terrain and habitat characteristics, monitoring sample points were set up, covering the mechanized farming roads in Xinlou Village, pond edges, ridges, farmlands, greenhouse edges, wastelands, vegetable fields, orchards, green belts, front and back yards, fish ponds, woods, schools and other locations, as shown in Tables 1-11.

[0036] Monitoring data collection: During the peak activity period of red fire ants and before and after the application of pesticides, monitoring surveys are carried out when the daytime temperature is 21℃ to 32℃ and the ground is dry. All roads passing through the outbreak area are closely monitored. The "cloud collection" system is used to collect the location information of red fire ant nests in real time, including the latitude and longitude coordinates of each nest, the time of discovery, the size of the nest and other detailed data. A. The number of live ant nests is monitored by the treading method. All locations in the monitoring area are observed on foot, and active ant nests are located using a GPS device. Obvious signs are inserted to record the number of live ant nests inspected. B. The number of worker ants is monitored by the ham sausage trapping method. Slices of pork ham sausage (thickness of about 1cm to 3cm) are placed in the bait hole of the red fire ant special collector, and the insect entrance is opened and placed upright on the ground. A collector is placed at intervals of about 10m to 20m, and the collector position is fixed with a red fire ant positioning label and numbered. Check after about 30 minutes. If there are red fire ant workers, quickly close the insect entrance, remove the insect collection tube and check the count. C. Occurrence assessment method: The number of live ant nests and the number of trapped worker ants per unit area are used as the assessment standard for the occurrence of red fire ants, which are divided into 5 levels. If the number of live ant nests and the number of trapped worker ants per unit area are inconsistent, the higher level shall prevail.

[0037] Secondly, after the monitoring and investigation of red fire ants, according to the distribution range and occurrence degree of red fire ants, the red fire ant nests were killed and controlled in stages. The red fire ant occurrence areas were divided into high-risk areas, medium-risk areas and low-risk areas; for high-risk areas, high-efficiency and low-toxic baits, powders or liquid medicines were selected, and a combination of spot application, broadcast application and nest filling was adopted to ensure that the medicines covered all the activity areas of red fire ants, and the medicines were applied at least once a month; for medium-risk areas, chemical medicines were mainly used, supplemented by biological control medicines, and the red fire ant nests and activity areas in the medium-risk areas were mainly applied by broadcasting and spot application, and the medicines were applied at least once a quarter; for low-risk areas, regular inspections were carried out, mainly by spot application, and the red fire ant nests found were applied. Through 3 comprehensive prevention and control, 3 consolidation prevention and control, and 5 continuous follow-up monitoring and investigation, the occurrence of red fire ants in Xinfa District, ZS Town was effectively eradicated, as shown in Table 12-17.

[0038] Finally, the prevention effectiveness survey and follow-up monitoring of the red fire ant nests after killing were carried out, and the next step of prevention and control was guided according to the monitoring results. After the prevention and control effect reached 100% eradication in August 2021, monitoring was carried out from August, and monitoring was carried out once a month thereafter; no red fire ants were found in the 8 consecutive months from August 2021 to March 2022, and the eradication effect in the newly-emerged areas was maintained at 100% for 8 consecutive months. The prevention and control method of intercepting and eradicating red fire ants in the newly-emerged areas of this embodiment completely removes the ant nests, and can timely, effectively and quickly control and kill red fire ants, thereby significantly reducing the harm of red fire ants to people's health and safety, and has significant economic, ecological and social benefits.
