Insect attack of trees in the forest and wood in service results in considerable economic loss. The
recognition of the damage by the various wood-boring insects is important, for some insects are pests of the moist wood only. Unnecessary treatments of houses carried out against insects such as wood moths and pinhole borers may leave a company exposed to charges of mis-representation.
A knowledge of the structure of trees and wood assists in the identification of. For instance, longicorns, jewel beetles, some wood moths and bark beetles attack the phloem and cambium, while the powder post beetles (lyctids and bostrychids) attack the sapwood only.
It is unlikely that pest control operators will be able to identify the in use today, but they should be able to separate pines from hardwoods and know the more character-istic species such as cypress pine, oregon, tallow wood, etc. A superficial knowledge such as this will supplement his entomological training, for he will know that powder post beetles do not attack pines and that the furniture beetle favours pines, except cypress pine.
