What should I do if the wood of a wood borer is eaten by insects?
Wood moth is a common moth (borer), which is the general name of CERATOPOGONIDAE, CERATOPOGONIDAE, COLEOPTERA, COLEOPTERA and COLEOPTERA. Among them, the first three kinds of insects mainly harm wood or living trees, and the insects of Dermatidae mainly harm skin, hair and its products. Moths are small, and adults are generally 2-3 mm long. Most of them overwinter as larvae in one year, pupate in the next spring, and pupate into adults in April and May. Adults lay eggs after mating, and the larvae hatched in about 15 days are harmful to wood or fur. It is an important pest of agriculture, forestry, wood decoration, furniture, wood carving, Buddha statue and leather clothing.
Drought resistance and hunger tolerance of moths
The moisture content of wood has certain influence on pests. Most moths have strong drought resistance, and almost all rely on the humidity in the air and the water content in the host to complete the whole life cycle, so as to meet their own survival needs. It rarely harms wood with water content above 30%, and only begins to harm wood with water content of 12- 15%. Wood with a moisture content of about 8% is the most harmful to it. On the other hand, sugar families like wood that is quite wet and begins to rot, but it is difficult for them to eat dry wood. Even if eaten, larvae living in wood grow and develop slowly. Long beetles, longicorn beetles and wood bees still have to survive in dry wood, but they can't survive when the humidity is high.
Moths have better hunger tolerance than other insects. Even in the case of complete lack of food, many species can still hibernate and semi-hibernate in different insect States, such as Dendroctonus valens, Dendroctonus valens, Cerambycidae and so on. But once the food supply is restored, when other conditions are suitable, it will move quickly and normally, causing rampant harm.
Effects of Wood Components on the Growth and Development of Pests
In recent years, with the increase of wood decoration, especially the increase of residential moth-eaten, it has seriously affected people's lives and gradually attracted people's attention. When environmental conditions permit, organic furniture is also vulnerable to pests and parasites. Common furniture pests include termites, wood borers, mealybugs and so on. These small insects smaller than 5 mm will enter the interior of furniture and eat, resulting in dense and empty caves. When they mature, they will fly out along the cave, mate and lay eggs again, and complete their life cycle. So always check the appearance of furniture. If there are many small holes on the surface, it is necessary to further identify whether it is infected by pests. If there are small and round holes in the wood products, larvae will feed on the wood products, which will lead to holes in the wood products. And there are some small powder like dust, which means there are pests in it. It is necessary to seal and isolate it with plastic bags immediately, and find relevant professionals to carry out pest control.
Moth control mode
1. Use insect-proof corner materials for decoration.
2. The wormholes in the damaged area should be perfused.
Three, all the corner materials in the dangerous area, the implementation of comprehensive residual spraying.
Strengthening methods of Buddha statues and artistic sculptures
1. The authority of sculpture reinforcement shall be explained to the owner of the work and approved.
2. Use B72 or acrylic resin with the concentration of 15% and 30% respectively.
3. Acrylic resin with the concentration of 15% can be injected into the depth of wood.
4. After dropping 30% acrylic resin, it can be used as the main fixing color.
5. If it is the back, you can drill from below and then inject.
How to eliminate moths at home?
1. Sprinkle diatomite on cabinets and dark places.
Diatomite is made of crushed fossil materials, and each particle has a sharp edge, which can pierce the exoskeleton of insects and can be fatal, but harmless to people or pets. 2. Another natural material can kill moths and moth eggs.
Sprinkle boric acid along the bottom of the cabinet, under the bathtub, and other places with insect-eaten marks. Be careful not to get it on yourself because boric acid is toxic and harmful to the lungs.
Remember to avoid using boric acid in places where pets haunt. 3. Chemical insecticide spray containing liquid pyrethrins.
This chemical can kill moths and spray it on the bottom and crevices of cabinets and other places where you think there are moths. Remember not to spray it on the cabinet or other places near food, and don't spray it where children and pets come into contact, because it is toxic.
Moth, a biting insect. It is also a metaphor for the bad guys who endanger the collective interests.
Beetles spread all over the northern and southern provinces of China, endangering Pinus massoniana, Pinus densiflora, Pinus armandii, Pinus tabulaeformis and Pinus sylvestris var. mongolica. Mongolian pine and black pine. Use adults and larvae to destroy twigs, branches or cut trees of pine trees.
Any damaged tip is easily broken by the wind. Extended data 1. Cut down the damaged trees to reduce the harm of pests, and immediately cut down the weak trees or dead trees that have been seriously damaged and carry out necessary pest control treatment.
Treatment methods: First, uproot the whole tree; The second is to remove the lateral branches and roots and burn them; The third is to cut the trunk into 3-meter-long blocks; The fourth is to dig a pit 1 m deep, 2 m wide and 4 m long; Fifth, put the trunk (segment) in and fumigate it with aluminum phosphide 3g/m3 (sealed with plastic film with a thickness of 0. 12mm) (3-5 days); Fifth, take out the tree segments, scrape off the bark and burn it. 2. Chemical control of trunk: For slightly damaged Pinus tabulaeformis, the method of spraying pesticides around the trunk and branches (from top to bottom) is adopted. The pesticide is a strong systemic agent such as 40% omethoate or toxic zinc, and a penetrating agent is added at the same time, and the concentration is 100-200 times. Spraying time is before 9: 00 am and after 5: 30 pm. Don't spray when it's windy and rainy, but do it at the same time.
Do a good job of antivirus when spraying drugs. 3. Spraying chemicals at the base of the trunk for prevention and control, removing weeds in the range of 0.5-0.8m around the base of the trunk, spraying wettable powder such as phoxim mixed with phosphorus, and shallow turning the tree tray to kill the overwintering adults.
