Ecological Interactions of Bark Beetles with Host Trees
Certain species of bark beetles in the insect order Coleoptera, family Curculionidae (formerly Scolytidae), are keystone species in forest ecosystems. However, the tree-killing and wood-boring bark and ambrosia beetles are also among the most damaging insects of forest products including lumber, paper, and ornamental/recreational trees. The pest status of these beetles has been elevated with th...
متن کاملMutualism and antagonism – Ecological interactions among bark beetles, mites
Symbiosis may be defined as: “the acquisition and maintenance of one or more organisms by another that results in novel structures and (or) metabolism”. Relationships among symbiotic organisms may change over time and ranges of resources. Other organisms may indirectly facilitate or interfere with these relationships. Interactions among bark beetles and their associated fungi and mites are comp...
متن کاملInteractions of Root Disease and Bark Beetles
Associations between root diseases and bark beetles (Scolytidae) constitute some of the most serious pest complexes affecting forests in North America and elsewhere. The interactive functioning of these pests derives from the following relationships: 1) root diseases predispose trees to bark beetle infestation by lowering resistance, and perhaps increasing attractiveness, of trees to the attack...
متن کاملTrees Wanted—Dead or Alive! Host Selection and Population Dynamics in Tree-Killing Bark Beetles
Bark beetles (Coleoptera: Curculionidae, Scolytinae) feed and breed in dead or severely weakened host trees. When their population densities are high, some species aggregate on healthy host trees so that their defences may be exhausted and the inner bark successfully colonized, killing the tree in the process. Here we investigate under what conditions participating with unrelated conspecifics i...
متن کاملMutualism and Antagonism: Ecological Interactions Among /13! Bark Beetles, Mites and Fungi
Insect-fungal complexes provide challenging and fascinating systems for the study of biotic interactions between plants. plant pathogens, insect vectors and other associated organisms. The types of interactions among these organisms (mutualism. antagonism. parasitism. phoresy. etc.) are as variable as the range of organisms involved (plants, fungi, insects. mites. etc.). We focus on bark beetle...
