[Economic Significance] Isoptera is a type of social insect with gregarious nesting habits and complex hierarchical differentiation. Because of its interesting habits and outstanding economic significance, it has attracted people's attention very early. Termites are the enemy of agriculture, forestry, water conservancy projects, houses and buildings, stored materials, etc. Its harm is destructive, hidden and widespread. There is a folk song like this: Tiny termites, with bodies like glutinous rice, not to mention not big, with copper heads and iron mouths. When passing through a mountain path, water will penetrate the bottom. If you ask about the danger, it will be a mile and a half. Characteristics of moth erosion include paper, cloth, beam-framed furniture, and wood fibers, endangering houses and threatening dams.

[Identification characteristics] Because the size and shape of the front and rear wings are equal, it is named Isoptera. The adults resemble ants, but are fat and especially colorless, so they are also called termites, for short. Body length is generally 3.5-6 mm. Antennae bead-shaped. Chewing mouthparts. Winged termites shed their wings after their nuptial flight, leaving only their wing scales. There are 10 abdominal segments, there are tail whiskers, and the external genitalia is not obvious.
