3 wood pests classification

Wood pests mainly divided into beetles, termites, bored animals. among them.

--- Beetle family including beetles, Anoplophora, Chinese pink beetle, Dryopteris flour beetles, beetles long bamboo, double hook iso aequalis, Ptilinus beetle;

--- Including termite termites, termite, termite heap of sand;

--- Drilling ship animals including worms, wood-boring water lice.

Specific hazards and characteristics of wood species, environmental conditions (hazardous) See Appendix A.

4 Hazard Class

In accordance with the beetles, termites harmful levels and hazard characterization of different regions of the province (region) is divided into five hazard class, each hazard class

Characteristics are given Table 1 respectively.

Table 1 Hazard level features

Hazard level features

Grade I no termite distribution, but does not rule out that the wooden structure beetle harm, harm to a lesser extent

II grade termite distribution, fewer species, harm was sporadic distribution, is also part of beetles harm

III grade termite distribution, fewer species, harm is obvious, common beetle activity more

Grade IV termites have more distribution, but the environment less, less serious harm, beetle activity more

V grade termite species are more suitable due to environmental, rampant termites, beetles activities also active

5 insects (ants) timber environment

Insects (ants) use of environmental classification of wood requirements in Table 2.
