Termites are social insects and build a communal nest. In the case of ''Coptotermes acinaciformis'', this is either in the root crown of a tree or underground. From this a network of galleries extends through the nearby soil enabling the workers to forage in the surrounding area without emerging on the surface of the ground. This termite can cause substantial damage to trees and the wooden parts of buildings. ==The colony== ''Coptotermes acinaciformis'' builds its nest at the base of a tree trunk or underground, and may form a mound. Subterranean passages extend from the nest for up to and allow the workers to access other sources of wood on which to feed. Subsidiary nests are often built in such places as the cavities in the walls of buildings but only in places where there is some moisture, perhaps from a leaking pipe. A large colony may contain more than a million termites.〔(【引用サイトリンク】title=The destructive species: ''Coptotermes acinaciformis'' )〕 Where the nest is in a living tree, a central "pipe" of material is eaten out and replaced with frass. A number of other trees in the immediate vicinity can be similarly tunnelled, invasion taking place through the living bark. This is in contrast to the initial invasion of a tree by a newly mated pair of reproductives. In the latter case, the invasion is via pre-existing damage to the trunk. Tree stumps and fallen logs in the area are also affected, and mound nests have been shown to persist even when the host trees have been eaten out. The galleries from the colony may extend over an area of . Another favoured nesting site is where soil has been disturbed in a building site and pieces of timber have been accidentally buried in moist soil. This sometimes happens under patios or around new buildings.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Coptotermes acinaciformis」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
