How scary termites are and how harmful they are

In different termite distribution areas in China, termites cause harm to various fields such as housing construction, reservoir dams, communications, transportation, industrial and agricultural production, but the degree of damage is different. In the economically developed areas south of the Yangtze River and in the distribution areas of termites, termite damage is serious. How much economic loss is caused by termite damage in China, about 2 billion to 2.5 billion yuan per year (National Symposium on Termite Control, Nanning, 1999).

Among them, Zhejiang, Jiangsu, Hubei, Jiangxi, Fujian, Sichuan and other provinces will reach at least 200 million yuan, and Shanghai, Anhui, Hunan, Guangxi and Chongqing will reach at least 100 million yuan. It is difficult to calculate the damage caused by termites to cultural relics, monuments, dams, reservoirs, etc. Termite damage is hidden and difficult to investigate, and it often brings heavy losses to China's economic construction achievements and people's lives and property.

In addition, it has been reported that termites can indirectly affect our ecological environment by polluting the air by emitting carbon dioxide and formic acid into the atmosphere, in addition to direct harm.

3) Harm object (food habit). House termites are able to eat wood, bamboo products, plastic products, and tables are very accurate in judging new.

Rubber products, leather products, cotton and linen, wool, silk products, chemical fiber fabrics, etc. Trees such as Eucalyptus, Eucalyptus, Eucalyptus, Weeping Willow, and Maple Poplar are susceptible to termite erosion, and termites often build nests in tree trunks. Family.

Ants erode crops such as taro, sweet potato, potato, and peanut, and in some areas, termites also seriously harmed Ganshu.

The harm of termites involves people's clothing, food, housing, transportation, use, etc., and all aspects of the national economy are mainly manifested in buildings, wooden furniture, crops and other items.

The damage of termites to the building is very serious, termites live in the dark for a long time, hidden in the wooden structure to destroy its load-bearing parts, often causing the sudden collapse of the house, resulting in property damage and personnel, although most of the buildings are now made of reinforced concrete, but the formic acid secreted by termites can also corrode the metal, so now the Ministry of Construction clearly stipulates that the newly built houses must be termite prevention.

Termites live in a dark environment for a long time, living a hidden life, furniture is harmed by termites, will not be found in a short time, because the surface of the furniture seems to be intact, inside is full of holes, once discovered, the loss is quite serious.

Termites can also harm sugarcane, peanuts and other crops, especially the damage to sugarcane is very serious, the damage to camphor, metasequoia, bayberry and other forest trees, fruit trees is also quite extensive and serious, termites can also harm books, cultural relics, fabrics, account books, coins, underground cables, etc., causing significant losses to the country.

Check the method of identifying termites

1. Shedding wings: can occur on windowsills and floors, which are usually the most common visible traces of termite damage.

2. Termites fly separately: Usually termite winged adults emerge from the ant nest in the evening when the weather is hot and humid and the air pressure is low from April to June, and fly under the lights.

3. Damage to wood items: termites like to eat wood from the inside out, so if the wood makes a hollow sound when it is struck, it means that there may be termite damage inside.

4. Mud quilt or ant road: termite worker ants and soldier ants are photophobic, and in order to avoid being attacked by natural enemies such as ants, ant roads are usually built near the foundation of buildings or on the surface of door frames, skirting boards, wooden floors, wall skirts, stairs, ceilings, etc., so that they can move back and forth between the nest and the food source (wood products).

Termites can eat a wide range of field crops, cash crops, trees, fruit trees and seedlings. The damage to river dikes is more serious by black-winged termites, and termites cause huge losses to the erosion of houses, storage materials, buried plastic cables, etc. The damage of termites to housing construction, especially to brick and wood structures and wooden buildings, is particularly serious.

Because it is hidden inside the timber structure, it destroys or damages its bearing points, often causing the house to collapse suddenly.

Generally speaking, termites are not important pests to crops in our country. The main species are Taiwanese termites, yellow-winged termites, black-winged soil termites, Hainan soil termites, and Taiwan milk termites. The types of termites that harm trees include new termites, sand-pile termites, house termites, tree termites, scattered termites, wood-nosed termites, soil termites and large termites, proto-termites, etc.

The species that damage river embankments include termite colonies of soil termites, large termites and house termites.

Termites can corrode**. Termites secrete a high concentration of formic acid, which reacts chemically with ** to form silver formate, which is a black powder that can be eaten by termites. The damage of termites is closely related to the condition of the substances contained in the tree such as tannins, resins, acid-base compounds, and the quality of the tree's growth.

Termite damage causes tens of billions of dollars in direct economic losses worldwide every year. China is one of the countries seriously affected by termites. There are more than 470 species of termites known in China, among which the most common main species that cause serious damage are Taiwan milk termites, yellow-breasted scattered termites, black-breasted scattered termites, black-winged soil termites, yellow-winged large termites, Qibei scattered termites, etc.

Termite damage areas are very extensive, whether it is housing construction, water conservancy and electricity, cultural relics and ancient buildings, landscape gardens, or agriculture, forestry and fruit trees, they have become the target of termite damage.

Hello dear, happy to answer your <>

Termites are insect pests, and their main hazards are reflected in the following aspects:1Erosion of fruit trees, flowers and other plantsTermites like to attack tree trunks, roots, bark and other parts, which will cause erosion of the root system of fruit trees, flowers and other plants, and even cause plants to wither and die due to lack of nutrients.

2.Corrosion and damage of wood and paper termites will build nests and find food on wood, paper and other items, and long-term erosion will cause the wood to become loose, the paper to become weak, and lose its original structure and function. 3.

Hygiene and health problemsWhen searching for food, termites will pass through underground garbage or sewage pipes to bring bacteria and viruses back to their hiding places. Termite-infested homes, buildings and other premises usually have foul odours and peculiar smells, which pose a hidden danger of affecting environmental hygiene and health problems. 4.

Damage to the structure of the buildingTermites often build nests in the basement and other hidden parts of the building, and long-term corrosion will lead to the loose structure of the building, and the beams, columns, brick walls and other parts will be difficult to crack and destroy, which may lead to the collapse of the building in serious cases. <>

To sum up, termites pose a great threat to our lives and environmental safety, and when termites are found, corresponding measures need to be taken to prevent and remove them. <>

Termites can eat a variety of crops, cash crops, trees, fruit trees and seedlings, such as rice, wheat, corn, peanuts, tea and other crops, as well as cedar, eucalyptus, aspen, hickory, bayberry and other forest trees. Termites damage a wide range of areas, including damage to housing construction, water conservancy and electric power, cultural relics and ancient buildings, landscape gardens, power cables, books and archives, paper, cloth, etc.

Termites have a wide range of eating habits, and their nutrients are the best in plants, with plant cellulose and its products as the staple food, and also eat fungi and lignin, and will also eat starch, sugar and protein.

Termites eat man-made fibers, plastics, wires, cables, bricks, stones, metals, etc., because termites secrete chemicals such as formic acid to corrode and melt these objects.

Kiss! Hello, happy to answer your <>

The harm of termites is that termites are wood-hungry and use wood fiber as the main source of nutrition. Therefore, blind wooden posts, wooden stakes, sleepers, pit wood, and even swing frames and trees have become a delicacy for termites. Due to termite damage, some wooden structures such as houses, boats and swing frames are often bored with countless holes like tunnels, and the wood also becomes decayed and fragile, and it is easy to break at the touch of a button, so accidents such as collapse, sinking and breaking often occur.
