V. Blockade Control and Extinction
The competent agricultural administrative department in the place where the red imported fire ants occur shall set eye-catching signs and boundaries on the ant nests and the activity areas of red imported fire ants in the occurrence area, and take measures to block, control and extinguish them.
(1) Blockade control
The relevant departments should conduct a comprehensive investigation on the airports, docks, stations, parking lots, areas on both sides of major traffic arteries, production units with products shipped abroad, and logistics distribution centers in the area where red imported fire ants occur, and the consignors and freight enterprises should actively cooperate with the relevant departments to do a good job in the prevention and control of red imported fire ants. Plant quarantine institutions can send people to participate in local timber inspection stations. When the harm of Solenopsis invicta is particularly serious, with the approval of the provincial people’s government, temporary plant quarantine inspection stations can be set up in the main traffic arteries around the occurrence area to quarantine the exported plant products and media such as seeds (seedlings), flowers, bonsai and turf, as well as waste materials, and prohibit the soil, garbage, building mud and compost from being transported outside the occurrence area of Solenopsis invicta to prevent the Solenopsis invicta from spreading with the water.
(2) Prevention and extermination
Vigorously carry out patriotic health campaign, clean up the garbage and other breeding grounds of red imported fire ants in the area where red imported fire ants occur, and keep the environment clean and tidy.
Regularly carry out the action of killing red imported fire ants, and use the two-stage control method to eliminate the nest of red imported fire ants, that is, first put bait to kill them, then dig the nest and spray or fill the nest with drugs until the red imported fire ants are extinguished.
Six, prevention of stinging and wounding treatment
It is necessary to remind people not to go to places where red imported fire ants occur to prevent red imported fire ants from stinging and hurting people. If it is necessary to work in the area where red imported fire ants occur, protective measures should be taken to prevent contact with red imported fire ants. After being stung by red imported fire ants, the wound should be treated in time.
VII. Investigation and monitoring
Agricultural plant quarantine institutions at all levels in the area where the red imported fire ant occurs and the surrounding areas should strengthen the investigation and monitoring of the local area, make records of the monitoring results, keep records and files, and summarize and report them regularly. Other areas should strengthen the quarantine and monitoring of plants and plant products from the occurrence area of red imported fire ants to prevent the introduction of red imported fire ants.
Eight, publicity and guidance
Propaganda departments at all levels should actively guide the media to correctly report the occurrence and control of red imported fire ants. Relevant news and information should be obtained through normal channels of government departments to prevent speculation and avoid social unrest caused by inaccurate reports. In the area where red imported fire ants occur, it is necessary to carry out popular science propaganda in an appropriate way, focusing on matters needing attention, preventive knowledge, prevention and control techniques and methods for preventing injuries. When there are false reports in the media or rumors circulating in the society, we should immediately clarify them positively, strengthen the guidance of public opinion, and reduce the negative impact.
IX. Emergency Support
(A) Team security
People’s governments at all levels should set up an emergency prevention and control team of red imported fire ants, which is composed of staff of agricultural administrative departments, plant quarantine personnel and relevant experts, strengthen the training of professional and technical personnel, improve the professional quality and professional level of emergency prevention and control team personnel, provide high-quality emergency team guarantee for the start of emergency plans, and set up a professional team to kill ants; It is necessary to fully mobilize the masses and implement group prevention and control.
(2) Material guarantee
People’s governments at the provincial, city and county levels should establish an emergency material reserve system for the prevention and control of red imported fire ants to ensure the supply of materials. In areas where red imported fire ants are seriously endangered, relief materials should be allocated in time to ensure the stability of the lives and production of affected farmers.
(3) Funding guarantee
People’s governments at all levels should arrange special funds for emergency prevention and control of red imported fire ants. When the emergency response is started, the local administrative department of agriculture, in consultation with the relevant departments, puts forward a plan for the use of funds, which will be appropriated by the financial department at the same level, and the departments of finance, agriculture and auditing will strictly supervise and inspect the use and management of special funds to ensure earmarking.
(4) Technical support

Attachment 1:
Technical scheme for investigation and monitoring of red imported fire ants
First, the identification characteristics
(A) morphological characteristics
Small worker ants (worker ants) of Solenopsis invicta are 2.5 ~ 4.0 mm long. The head, chest, antennae and feet are all brown, the abdomen is often brown, the color between abdominal segments is slightly pale, and the center of the back of the second and third abdominal segments often has nearly round pale markings.
The front end of the anterior thoracic backboard is raised, and the joint between the anterior and middle thoracic backboards is not obvious; The joints between the middle and back thoracic backbones are obvious, and there are two nodules at the thoracoabdominal junction. The first nodule is flat and conical, and the second nodule is conical. The abdomen is ovoid, with 4 segments visible, and there are pincers protruding from the end of the abdomen.
Large worker ants (soldier ants) are 6 ~ 7 mm long. The shape is similar to that of a small worker ant, with orange-red body, slightly darker abdominal backboard, developed upper jaw, dark brown, slightly shiny body surface, short and small body hair, and no exposed claws.
(2) characteristics of ant nests
Solenopsis invicta is a completely terrestrial ant nest, and the mature ant nest is an ant mound with a height of 10 ~ 30cm and a diameter of 30 ~ 50cm. The newly formed ant nest appears obvious mound-like ant mound after 4 ~ 9 months. When the nest is disturbed, the red imported fire ants will quickly leave the nest and attack the invaders.
(3) Hazard characteristics
Solenopsis invicta mainly harms plants, animals and human bodies by stinging with pincers and biting with mouthparts. After being stung by it, the human body will feel pain like a fire, and then there will be blisters like burns. After 8 ~ 24 hours, the sting will fester and form pustules.
Investigation and monitoring of occurrence and distribution of red imported fire ants
(1) Interview and investigation
Ask local residents about the place, time and harm of red imported fire ants, and analyze the spread and spread of red imported fire ants and their sources. Each community or administrative village asked more than 30 people to investigate. In-depth investigation was conducted on the suspected areas of red imported fire ants found during the inquiry.
(2) Field investigation
1. Investigate the region
Focus on the investigation of overgrown wasteland, farmland ridges, places close to water sources, dams, roadsides, village roads, lawns, green spaces, corner of houses, garbage dumps near courtyards, parks, schools and other places.
2. Investigation methods
Each administrative village or community has not less than 10 plots of each type of investigation, and the investigation area of each point is more than 50M2. The investigation points should be representative and cover the whole village or community. Observe whether there are mounds or sand-pile-shaped ant nests, record the occurrence area, occurrence range, occurrence density, diameter and height of the mounds or ant nests, and push aside the surface of the ant nests to observe whether the ants quickly leave the nests and show strong aggressive behavior.
(3) decoy trapping monitoring
1. Preparation and dosage of bait
Bait composition: 95% peanut oil, 5% white sugar or honey. If white sugar is used, boil it into syrup. Add peanut oil and white sugar or honey to dishes according to the ratio of 95: 5, stir and mix evenly, and put them into shallow dishes (disposable paper dishes with a diameter of about 15CM), each dish is about 10G, and make bait.
2. Bait release
There shall be no less than 5 bait placement points for various types of plots in each village or community. Put the bait in the shade of the ant’s suitable area, preferably in the place where ants are active. Pay attention to make the edge of the saucer with bait stick to the ground to facilitate ants to climb up. Each point has an area of more than 50M2, and five decoys are placed at random with a distance of more than 5M.
Step 3 investigate
Observe once a day, and change the bait for 5 consecutive days (except rainy days). Observe whether the trapped ants are reddish brown. If suspicious ants are found, follow up the surrounding ant nests and ant behavior characteristics. If found, collect samples of ants in the nests.
Third, sample collection and delivery
If suspicious ants are found in the investigation, soak them in 70% alcohol or kill them with pesticides, and indicate the collection time, collection place and collection person. Collect the ants collected at each point in a specimen bottle, and collect more than 50 suspicious ant specimens. Send the samples to the provincial plant quarantine station to ensure the safety of the samples during transportation.
Iv. requirements of investigators
Investigators are required to be full-time plant inspectors or trained plant protection technicians. The main contents of the training are the morphological and biological characteristics of Solenopsis invicta, combined with behavioral characteristics, ant hill characteristics, harmful symptoms and investigation and monitoring methods and means of Solenopsis invicta.
V. Handling of survey results
In the investigation and monitoring, once the red imported fire ants are found, the reporting system must be strictly implemented, and they must be reported step by step within 24 hours, and the investigation and monitoring situation should be reported to the higher government and relevant departments step by step every 15 days.
Attachment 2:
Technical scheme for prevention and control of red imported fire ants
I. Blockade and quarantine measures
(1) Blockade and quarantine
1. Make a carpet survey in the area within 50M on both sides of the main traffic trunk passing through the fire ant occurrence area, thoroughly remove the ant nest, trap and kill the fire ant, spread a lime belt (1M wide), and whitewash the trunk of the roadside trees with lime water (about 80CM high).
2. Strictly control the external logistics of the fire ant occurrence area and prevent the fire ant from spreading abroad.
(1) Conduct a thorough investigation on the logistics of the manufacturers and enterprises in the occurrence area. For the units with bulk goods to be transported abroad, a special person shall be responsible for the quarantine work of the place of origin. At the same time, the means of transportation in the production site and the freight place shall be treated with ant extermination, and inspection shall be carried out before loading to prevent the red imported fire ants from coming out with the goods.
(2) Strictly inspect the articles, containers, means of transport, gardening and farming machines and equipment transported from the occurrence area, focusing on whether the packaging and contents of the goods contain red imported fire ants, and whether the corners and bottoms of the means of transport, containers, etc. are hiding ants. If red imported fire ants are found, they should be handled in time to prevent them from being transported with the goods.
(3) Clean up and exterminate ants in the parking lot in the occurrence area, and set up a pesticide toxic soil isolation belt (about 1.0M wide).
(4) It is forbidden to transport garbage, waste soil, building mud and compost outside the area where it occurs. Only seedlings, flowers, bonsai and turf with soil can be transported outside after strict quarantine.
(5) Strengthen the inspection of river banks flowing through the occurrence area, thoroughly eradicate the nest of red imported fire ants along the coast, and prevent them from spreading with the water.
(6) Strengthen the training of quarantine, blockade, investigation, monitoring and control technology, increase the publicity of Solenopsis invicta control, raise the awareness of the masses, and make them take actions to prevent proliferation.
(two) the quarantine treatment agent and the use method
If the goods, packages and means of transport transported from the occurrence area are infected with red imported fire ants, they must be treated with drugs.
Seedlings, flowers, bonsai and turf with soil can be treated with the following chemicals: abamectin, cypermethrin, bifenthrin, sevoflurane, fipronil, chlorpyrifos, etc., by spraying, soaking or watering. Vehicles and containers can be disinfected by spraying the above chemicals or fumigation. The use concentration of the medicine refers to the instructions for the use of goods.
Second, the fire ants extermination measures
According to the characteristics of occurrence and damage of Solenopsis invicta, the combination of environmental control and chemical control can be adopted to control and extinguish it.
(1) Clean up the environment and eradicate the breeding ground of red imported fire ants.
1. Residential areas
Do a good job in indoor cleaning and hygiene, often clean up the debris or food piled up on the floor and the foot of the living room, remove garbage and food residues, and minimize the environment suitable for the survival and harm of red imported fire ants. Clean up the sundries near the house, remove weeds and dredge the drainage ditch, and sprinkle lime around the ditch to prevent ants.
2. Wasteland
For the wasteland where the density of ant nests is high and the weeds are overgrown and difficult to treat, herbicides can be applied first, and the ant hills are exposed after the weeds dry up, and then chemicals can be used for control. In the barren slope land with low density of ant nests, after the ant nests are found, herbicides are sprayed on the ant hills and the weeds around them, and then chemicals are used to control them.
3. Farmland and dry land
Remove weeds, shrubs and soil miscellaneous fertilizers around the cultivated land, and cut off the ant path leading to the field.
4. Garden green belt
Remove litter and garbage in time, and brush tree trunks and ground roots with limewater to prevent insects and ants.
5. Garbage disposal
Thoroughly clean up the garbage and garbage collection points in the occurrence area, treat the garbage on the spot by pesticide treatment or high temperature composting, and prohibit foreign transportation to prevent spread. Be careful not to abandon and pile up garbage and waste products in the wild and residential areas.
(2) Chemical control
The control was carried out by applying pesticides step by step and finally extinguishing. Firstly, bait is put into the active foraging area of Solenopsis invicta near the anthill, and after 2-4 weeks, the ant nest is filled with drugs or directly treated with drugs. After prevention and control, continuous monitoring should be carried out, and the red imported fire ants should be repeatedly treated with bait and medicine according to the actual situation until no red imported fire ants are found within 9 months.
1. bait poisoning
The number of individuals in the ant colony is determined by the number of eggs laid by the queen ants, and the queen ants often live in the depths of the ant nest and rely on the workers to feed the pre-digested food to survive. Because of this characteristic, it is generally difficult for insecticides to kill queens, which leads to difficulties in control. The bait is made of slow-acting pesticides and food attractant materials (such as vegetable oil), which will not kill the foraging worker ants quickly. Worker ants are attracted by the oil. After finding the bait, they bring it back to the nest. After being digested by the young ants, they are fed to the queen and the developing young ants. After feeding, the red imported fire ants will eventually be poisoned and die, thus destroying the whole ant colony.
Insecticides used to make baits are:
Remarks on Effective Time of Effective Component Content in Pharmaceutical Name
Fuyihydrazone can be used indoors after 0.73-1% for 2-4 weeks.
Formicidin 0.5% takes effect in 6-8 weeks.
Fenoxycarb 1.0% takes effect in 6-8 weeks.
0.5% nitenpyram takes effect in 8-12 weeks.
Avermectin 0.011% can be used indoors after 6-8 weeks.
Fipronil 0.008% takes effect in 2-4 weeks.
Spinosad 0.015% takes effect from 3 days to 8 weeks.
Preparation method of bait:
Peanut bran, biscuits and bread crumbs can be used as carriers, and the drug can be dissolved in vegetable oil such as soybean oil and mixed with the carrier to make bait.
Application method of bait:
You can choose a place where the Solenopsis invicta is active and foraging for food, or you can treat it in a single nest. The dosage is 1-1.5g per 10m2, and it is generally put at a distance of 1.0-1.5m from the nest. It should be used as far as possible when the soil temperature is 20-30℃ and the workers come out for food. After the first feeding, it is advisable to feed the bait once every 4-5 weeks.
Precautions: (1) Don’t destroy the ant mound and disturb the ant nest to prevent the red imported fire ants from moving and spreading; (2) using fresh bait; (3) Do not mix bait with other substances; (4) Do not apply pesticide in rainy days, but apply it to dry ground, and try to avoid direct sunlight; (5) When the daily average temperature is higher than 20℃, the bait has better effect; (6) In the pesticide application area, obvious warning signs (sanitary pest control, etc.) should be inserted to avoid poisoning people and livestock or other accidents.
2. Treating ant nests with chemicals
Suggested chemicals: chlorpyrifos (chlorpyrifos), cypermethrin, abamectin, imidacloprid, spinosad (Caixi), fipronil (Regent), carbaryl (carbaryl), deltamethrin (fenvalerate), etc. Prohibit highly toxic and residual pesticides. The concentration of the above drugs is prepared according to the instructions of the commodity. Nest filling: liquid or wettable powder is mixed with water and slowly poured into the nest. The amount of liquid medicine used in each nest is generally 10-15 liters, and the amount of liquid medicine is appropriately increased for larger nests.
(1) Abamectin, spinosad, cypermethrin, deltamethrin and other chemicals are recommended to kill ants in residential areas, public buildings, schools, factories and enterprises, and the methods of applying pesticides can refer to the methods of health pest control. After applying pesticides in HOS houses, open the windows for ventilation. Drug use in residential areas, public places, schools, factories and enterprises should avoid the peak of people flow.
(2) Attention should be paid to minimize the impact on pedestrians when killing ants in urban garden green belts; Safer drugs should be used in parks, squares, golf courses and other crowded places, and regent and imidacloprid can also be used in other places with less people. Attention should be paid to the safety of people and animals in the application area.
(3) Paddy fields, dry land, orchards and wasteland.
It is suggested to use one of the above drugs, and pay attention to the influence on bees.
(4) Attention should be paid to the safe use of drugs in areas near rivers, reservoirs and fish ponds, and abamectin, pyrethroids and regent should be banned to prevent water pollution and avoid killing fish and shrimp.
Three, the prevention and control effect inspection and tracking monitoring
1. After using poison bait for control, several ant nests should be dug up at random 2-4 weeks after application for inspection. If ants are still active in the nests, they should be filled with drugs, or bait can be spread to continue poisoning and repeated application.
2. After 2-4 weeks of treatment with chemicals, select multiple monitoring points in the prevention and control area, and pay attention to covering the whole prevention and control area. Choose an area of 50 square meters for each point, and randomly set up 5 traps (peanuts and syrup can be used) for monitoring, trapping continuously for 3 days each time, once a month.
