Termites
Most of the termite eggs begin to hatch, as young ants, ant larvae after differentiation into soldiers, workers and nymphs, if further development to supplement ant queen termite and long winged reproductives, long winged reproductives after removal of fly wings, as the original Queen, the queen. Termites have remarkable ecological characteristics: group life, covert activities, good cleaning, sensitive information, and breeding in groups. Termites are imperfect metamorphosis of the metamorphic class, complex life history. Termites can be divided into two categories according to their living habits. Is a wood dwelling termites: population size, in wooden buildings, such as wooden doors and windows, wooden floors, wooden houses, railway sleepers, wooden bridges, trees and other mesh empty nest feeding part, wood fiber, wood products for major pests. The wood was made hollow and the building collapsed easily. Rail sleepers are damaged, affecting service life, and threatening traffic safety greatly. Two is the termite: under the ground soil in the nest, the nest or above the tower like, called the anthill. Ground dwelling termites feed on trees and leaves and fungi. China's Taiwan, 1 common species of termite; 2, yellow, Reticulitermes chinensis; 3, Odontotermes Macrotermes barneyi light; 4, 5; and CRYPTOTERMES domesticus.
Termite damage
The damage of termites to buildings, especially in tropical and subtropical areas, is especially serious. There are three characteristics outlined below:
• concealment: termites are covert insects, afraid of the sun. Harm the trees and other items, the appearance of seemingly intact, but inside in a disastrous state "". The year May 4, a large number of reproductives fly, paired landing, survival and reproduction, building a new nest. Termites build nests in the soil, walls, or wood. Serious - termite termite species in Guangdong area, the foraging activity radius of up to 100 meters above the nest place, can decay the hard wood and corrosion of reinforced cement, construction of tunnels, to leave the nest to go foraging, once found, the harm is very serious.
• extensive: termites are dangerous and involve a wide range of industries, such as housing, construction, transportation, telecommunications, cables, wires, trees, books, fabrics, etc.. In short, people suffer from clothing, food, shelter, shelter and utensils.
- severity: because termites erosion and high reproductive capacity, can cause some houses collapsed, old trees broken, damaged and disappeared and other important information, causing great harm to people's normal life and irreparable loss.
First, ecological prevention law 1., select natural termite resistant species 2., clear termites habitats, 3. use wood protective agent
Two. Biological control mainly uses the natural enemies of termites, such as certain bacteria, fungi, viruses and protists, or their metabolites, to control termites.
Three, physical and mechanical control method of 1. nest digging method 4. building sand barrier 5. biophysical method using high frequency current and microwave processing method 3. 2. trapping heat kill, kill termites
Four, chemical control method is the main method of termite control, mainly using stomach poison, contact killer, fumigant, through certain pesticide application methods, to achieve the purpose of termite control.
How do you determine if there are termites?
1, fly - winged adults from the outdoor light on flying into the room, select the appropriate part of building nest and breed harm.
2, residual - the original building, termites in the ground, the construction did not clear completely.
3, climb into the surrounding termites in the environment, through the soil layer into the building, feeding damage.
4. Moving belts - wood with termites; used for new houses and furniture, or for termites into the interior.
Two, found in termites, the wooden doors and windows box by a certain distance from the bored liquid, the surrounding soil and spraying liquid, wood and soil contain certain toxins, termite activities will contact poison feeding poisoning death.
Three, trapping method, which can be found in the termites to set up booby trap trap pit, pile, pile, inducing anti-virus bait. The above three kinds of ant killing methods can be used alone and can be used in a comprehensive way. In addition, there are fumigation methods, such as the use of hot gas abroad, killing methods, but also to some extent achieved good results. There are many ways to kill termites, but they must be treated according to the specific environment and the surrounding conditions of termites, so as to formulate specific methods of killing.
