The main habits and hazards of termites, how to prevent them?

Termite is an insect with strong organization and high division of labor. Its life is always inseparable from the surrounding natural environment. In order to adapt to the environment and survive, termites have certain life rules.

1, gregarious

Termites are insects that live in nests. No matter what kind of termites are, they build nests and take nests as their base camp. However, due to the different species of termites, the structure of ant nests can be divided into simple and complex. Huge ant nest, although tunnels crisscross, connects several main roads to the main ant nest to form a whole. Queens and queens in ant colonies live in palaces for a long time. The sex organs of winged reproductive ants are immature, and if they are not frightened, they will not stay away from the nest heart; Worker ants and soldier ants have special functions, so they should often go out and never go back. In their external activities, the longest time is usually four to seven days, and their internal relations are very close, which looks like a whole.

2. Darkness

Termites are afraid of light, tend to be dark and live a hidden life. It goes out to eat and absorb water, and digs tunnels in the ground or wood. Even if you leave the object and go to another feeding place, you should build a mud pipe or mud quilt channel in advance to be isolated from the outside light.

Step 3 get wet

The life of termites is very important to water. They can't live without water. The water content of termites is 79%.

Step 4 clean

Termites have a neat feature. When individuals meet, they clean up each other. I lick you and you lick me. They not only lick each other, but also feed each other. They also devour the bodies of the same kind and remove excrement such as feces and peeling in time.

5. Thermotaxis

Termites, like other insects, are also warm-changing animals and warm-loving insects. Temperature is the main factor affecting the distribution of termites. Different kinds of termites have different requirements for temperature. For example, Reticulitermes nigricans, a species that can live in the north, can adapt to the low temperature in the northern provinces.

6. Sensitivity

The activities of termites are very sensitive to external interference.

7. Hobbies

Cellulose accounts for a large proportion in termite diet.

8. grouping

The spread of termites mainly depends on emergence and clustering. It takes more than five years for termites to form mature nests from young nests to mature nests, and winged adults differentiate.

Second, the harm

Harm to crops: Generally speaking, termites are not important pests of crops in China. However, the harm to the cash crop sugarcane is still serious. Its main species are: Taiwan Province termites, yellow-winged termites, black-winged termites, Hainan termites and Taiwanese milk termites.

2. Harm to trees: There are many kinds of termites that harm trees, including new termites, sand-piling termites, house termites, tree termites, scattered termites, wood-nosed termites, native termites, giant termites and native termites. Damage to buildings: termites damage buildings, especially brick and wood structures. Because it is hidden in the wood structure, it destroys or damages its bearing points, which often leads to the sudden collapse of the house, causing great concern. In China, termites that harm buildings mainly include; Domestic termites, termites and other genera. Among them, the species of domestic termites are the most serious termites that harm buildings. Its characteristics are strong diffusion, large population and rapid destruction, which can cause huge losses in a short time.

3. Harm to riverbanks: The severity of termite damage to riverbanks has been recorded in detail in ancient documents in China, especially in modern times. There are termites belonging to termites, termites and termites. They nest densely in dams and breed rapidly. Nurseries are dotted (except termites) and ant paths extend in all directions. Some ant paths even cross the internal and external slopes of the dam. When the water level rises in flood season, there is often the danger of pipeline leakage, and even more, it leads to dam failure. Termites corrode silver. Termites secrete high concentrations of formic acid, which reacts with silver to produce silver formate. Silver formate is a black powder that will be eaten by termites.

Third, prevention and control

1. Ecological prevention and control law: Ecological prevention and control law is a prevention and control method that takes all necessary measures or carries out various activities according to the requirements of termite prevention and control in buildings and water conservancy projects before construction, during construction, after completion and a series of planting work to create an environment that is not conducive to termite breeding and protect buildings, earth dams and agricultural and forestry crops from termites.

2. Biological control method: Based on the interspecific struggle in nature and the relationship between termites and fungi, natural enemies of termites are used to control termites, and fungal indicators are used to find nests.

3. Physical and mechanical control method: a method of controlling termites by using labor, instruments and physical energy such as light, heat, electricity, sound and waves.

4. Nest-digging method: it is a method of artificially digging out the nest of ants after killing them and controlling their reproduction. Generally, this method is adopted under the premise of not destroying the green landscape, and it is best to do it in winter, because the weather is cold, and the remaining termites will be frozen after digging the nest, which can completely eliminate termites. You'd better apply some termite medicine after digging the nest.

5, drug killing method: it is to spray termite drugs in the traces of termite eating, so that it has powder on its body. When termites with powder are transported back to their nests, other termites find that there are unclean things stuck in them, and they will use mouthparts to help clean them up. At this time, the powder will be passed on to other termites, resulting in the poisoning and death of the whole nest of termites. The main method is as follows: a, mixing 100 part of sand with 1 5% Mi Le particles, digging a circle at a distance of 0.3-0.4 meters from the damaged tree foundation, and evenly smearing; B. Pollen contains chronic pharmaceutical ingredients such as chloric acid, mirex and fipronil. It is scattered in places where there are many termites (such as ant excreta, pores, ant nests and so on). ), and insert a screwdriver into several holes to spray it properly, and check whether all termites died of poisoning in 1 week or 1 month; C. During the peak period of termite activity, for termites endangering trees, it is advisable to spray 1000 times of Loeb solution or 500 times of cypermethrin solution on mud lines or mud quilts, so that the mud lines are fully wet and the soil does not fall.

6. Trapping and killing method: When termites are found, but no nest is found, and the nest cannot be dug out, and the number of termites is too small to be completely eliminated by drug killing, it is best to use trapping and killing method. Mix 100g sucrose and 150g fine rice bran evenly, add 100g water and heat to paste. After a little cooling, mix 15g of 70% mirex powder with 10ml of Roben, smear it on paper to make traps, and place the traps at the bottom of the tree.

7. Chemical prevention and control method: using various toxic chemicals-chemicals, through certain methods, directly contact termites, or treat habitats, breeding grounds and harmful substances, so that termites are poisoned to death by contacting or swallowing chemicals, or they cannot be harmed. It is characterized by quick response, high efficiency, simple use and little geographical restriction.

Four. comment

1. Air: These holes are the windows of termites' nests. In places where termites are numerous and dense, air holes are needed for ventilation or temperature adjustment. Small pores are as big as needle eyes, and large pores are as big as beans, and there is no fixed arrangement law. Picking up the air hole, a large number of soldiers immediately climbed out to guard, and workers immediately blocked the hole.

2. Grouping holes are generally above the ant nest and close to it. The grouping holes are slightly larger than the air holes. In the "flying" season, there are breeding ants with wings waiting to fly out in the waiting room. If disturbed, winged breeding ants will fly out immediately. It is easier to find the ant nest by using group holes or air holes. Then look for the ant nest according to the inspection and judgment. When ant nests are found, they should be eliminated by digging nests, using drugs and trapping. It is forbidden to spray pesticides such as black whirlwind or burn with hot water.
