Abstract
One of the best studies of a xylophage consortium is the case of larch insects by Isaev and Girs (1975). In their book, a basic theory was presented about host responses to xylophagous insects injury. According to their concept of "sliding resistance," different trunk-infesting insect species have different reactions to the tree's defenses and invade the tree successively depending on the stage of its decline or dieback With regard to the general tree status, groups of invaders were identified by the authors: 1) primary species invading living trees whose resistance may increase back to the initial level; 2) secondary species colonizing living trees with fatally disturbed metabolism, and 3) necrophagous species living only in dead trees.
