Vector biological control measures, the content of vector biological control

Vector control measures are as follows:

1. Rodent extermination: From February to May and from July to November, focus on consolidating the results of rodent extermination, organize and carry out large-scale rodent extermination activities in spring and autumn and winter in a timely manner, adhere to the combination of surprise rodent extermination and frequent rodent extermination, and strengthen the construction of rodent prevention facilities.

2. Fly extermination: From March to October, combined with the spring patriotic health month activities and the summer health special management activities, vigorously do a good job in environmental governance, reduce and eliminate fly breeding sites, do a good job in the absorption and treatment of garbage and feces, and take long-term measures to cure the root cause of key breeding sites and comprehensively carry out prevention and control.

3. Mosquito control: From May to October, do a good job in mosquito control, effectively control mosquito breeding sites, control and eliminate grass conditions, dredge waterways, fill potholes, do a good job in the comprehensive management of large, medium and small water bodies and all kinds of water storage containers, eliminate mosquito breeding conditions, and do a good job in mosquito prevention work in sewers and basements.

Fourth, cockroach extermination:

From April to September, do a good job in cockroach extermination, organize and carry out large-scale mass cockroach extermination activities in a timely manner, and adopt the method of combining environmental management and chemical sanitize to eradicate breeding sites. Key areas and units should be closed and sanitized, and centralized management should be carried out to further reduce the density of cockroaches and prevent the expansion of the infringing area.

Vector organisms refer to organisms that can directly or indirectly transmit diseases, endanger and threaten human health.

Vector organisms refer to organisms that can directly or indirectly transmit diseases and endanger or threaten human health, including rats, mosquitoes, flies, cockroaches, fleas, ticks, mites, bed bugs, etc. Among them, the most common vector organisms closely related to people's daily life are: mosquitoes, flies, mice, cockroaches, fleas, etc.

Vector organisms can transmit a variety of diseases, including malaria, Japanese encephalitis, dengue fever, Zika virus disease, filariasis, plague, hemorrhagic fever, fever with thrombocytopenia syndrome, allergies, etc. In addition to transmitting diseases, vector organisms can affect people's quality of life, jeopardize industrial and agricultural production, and cause huge economic losses.

How to control vector organisms

The control of vector organisms should follow the principle of comprehensive control, with breeding site treatment as the mainstay, supplemented by physical, chemical and other control measures, so as to control the density of vector organisms at a level that is not harmful to the victims. On this basis, physical control measures such as instrument hunting and chemical control measures such as pesticides can be selected according to time and place, so that the density of vector organisms can be quickly reduced and the density can be controlled at a low level for a long time.

Food production and business operation units should first improve the construction of protective infrastructure such as rat guards, rodent-proof fence nets, screen doors and windows, air curtains at entrances and exits, rubber curtains, etc., remove food residues and garbage and other breeding sites, as well as wall holes, gaps and other breeding places, set up sticky trapping equipment and maintain and update it in a timely manner, and try to avoid the use of chemical drugs to kill.

A variety of methods are combined, environmental, physical, chemical, ecological, biological, cultural, etc., environmentally friendly, environmentally friendly, less harmful to personnel, and fundamentally solve the problem.

Vector control refers to the prevention and control of the occurrence and spread of vector-borne infectious diseases.

Vector organisms refer to organisms that directly or indirectly transmit diseases (referring to human diseases) and endanger or threaten human health. Hazards of vector organisms: They can directly affect or endanger the normal life of humans through bites and contaminated food.

A range of important infectious diseases are transmitted through a variety of routes.

Measures for the control of vector organisms:

1. Breeding site management is a fundamental measure for vector control. From the source, completely improve the breeding ground of vector organisms, eliminate the breeding and living environment of vector organisms, reduce the density of vector organisms, and reduce the harm of vector organisms. Mosquitoes come from water; Flies come from dirty; The rat came out of the hole; Cockroaches come from crevices.

2. Mosquitoes cannot reproduce without boiling water, so cleaning up various indoor and outdoor small stagnant ponds in time can effectively control the density of mosquitoes. The breeding of flies is inseparable from dirty places such as garbage and feces, and good environmental sanitation is the key. Rats survive and reproduce mostly in holes, plugging various holes, not dumping food waste into the sewer, and managing garbage feces can reduce their reproduction and harm.

Cockroaches are parasitic in some small crevices, and places where cockroaches are easy to breed such as kitchens, warehouses, and power distribution rooms should be sewn up in time to prevent breeding.

3. Increase the necessary protective equipment to prevent vector organisms from coming into contact with humans to reduce the harm. Increase door curtains, window screens, floor drains and rodent-proof nets, and use cement or putty to seal various holes that communicate with the outdoors to prevent vector organisms from entering the room and reduce contact with people.

4. Take killing measures in a timely manner to reduce the density of vector organisms. It is mainly sanitized by physical methods, supplemented by chemical disinfection. The eradication of chemicals focuses on the use of new technologies and methods, the use of green, environmentally friendly, high-efficiency and low-toxicity health pesticides, the control of vector organisms, and the reduction of various measures, especially the adverse effects of chemical control measures on the natural environment and human health.

The "system" of vector biological control should be the system of the system. The meaning of the phrase vector biological control is:

The "prevention" and "control" of vector organisms such as rats, flies, mosquitoes, cockroaches, etc., prevention refers to the "four prevention" facilities, such as fake rat holes, fly curtains, fly windows, rat nets and other appliances;

System refers to the killing of rats, flies, mosquitoes, cockroaches, such as the use of chemical drugs, rat cages, fly lamps and other physical killing, with rats, mosquitoes, flies, cockroaches and other natural enemies to kill, such as: cats, snakes, etc.

The contents include: 1) the use of microbial control. The common ones are the application of fungi, bacteria, viruses and antibiotic bacteria that can secrete antibiotics, such as the use of Beauveria bassiana to control Masson pine caterpillar (fungus), various variant preparations of Bacillus thuringiensis to control a variety of forestry pests (bacteria), virus crude extract to control cypress moth, pine caterpillar, paulownia big bag moth and other (virus), 5406 to control seedling blight (actinomycetes) and microsporidia to control the larvae (protozoa) of Gyrovira vulgaris, Taishan No. 1 to control longhorn beetle (nematode).

2) Use parasitic natural enemies for prevention and control. There are mainly parasitic wasps and parasitic flies, the most common are red-eyed wasps, parasitic flies to control pine caterpillars and other pests, swollen-legged bees to control longhorn beetles, and flower horn aphid wasps to control pine round scales.

3) Use predatory natural enemies for control. There are many such natural enemies, mainly insectivore, rodentivorous vertebrates and predatory arthropods. Birds have different insect states that prey on pests, such as, grey sparrows, and woodpeckers.

Natural enemies of rodents such as weasels, owls, snakes, etc., and predatory natural enemies of arthropods include ladybugs, praying mantises, ants and other insects, as well as spiders and mites.

Legal analysis: 1. This system is formulated in order to eliminate the harm of rats, mosquitoes, flies, and cockroaches (hereinafter referred to as the four pests), prevent the spread of diseases, and protect the health of the masses.

2. The prevention and control of vector organisms should implement the principle of prevention first, adhere to the principle of combining the centralized and unified elimination of the "four pests" with the daily elimination of the "four pests", and the combination of environmental management and elimination of the breeding conditions of the "four pests" and direct sanitize of the "four pests".

3. Actively participate in the patriotic health campaign, regularly carry out environmental sanitation cleaning, eliminate sanitary dead ends, and eliminate the breeding grounds of the "four pests".

4. The responsibility system for the prevention and control of vector organisms shall be implemented, and all members must conscientiously study, master the knowledge and skills related to the elimination of the "four pests", adopt scientific, safe and effective methods to control and reduce the density of the "four pests" and meet the standards stipulated by the state.

5. Improve anti-rodent and rodent control facilities, and take methods such as blocking holes, setting up anti-rodent nets, poisoning, and sticky trapping.

6. Do a good job in eliminating stagnant water, waste management, etc., improve screen doors and windows and fly curtains, configure mosquito and fly lamps, and adopt various effective methods to control and eliminate mosquito and fly breeding conditions, and eliminate mosquitoes and flies and their larvae.

7. Cockroaches are killed as they are seen, eliminating hidden gaps and effectively controlling the density of cockroaches.

8. Do not use highly toxic drugs banned by the state to eliminate the "four evils".
