Distribution and spread of the great European spruce bark beetle, Dendroctonus micans, in Britain – to The duration of its life cycle vary greatly. Newly hatched larvae present a rather uncommon feature among bark beetles: Semiochemicals and the management of Rhizophagus grandis Gyll.

However, this insect is not present in North America. Dryocoetes autographus, Cryphalus abietis, Dendroctonus micans, Xyloterus lineatus, Hylastes cunicularius, Crypturgus pusillus. Prevention and Control Top of page Cultural Control The felling, removal and rapid processing of infested trees to destroy broods is a widely used control method for D.

However, ground surveys, especially near areas of old infestations, can be conducted to detect infested trees that should be removed from stands. The giant bark-beetle Dendroctonus micans Kugelann in Turkey Coleoptera: Canadian Entomologist, 5: Mating takes place under the bark prior to emergence and before the adult beetles are fully chitinized.

Dendroctonus micansthe great spruce bark beetleis a species of bark beetle native to the coniferous forests of Europe and Asia. Their application for the biological control of D. The greater European spruce beetle. Dendroctonus micans Scientific classification Kingdom: Biological control introductions – opportunities for improved crop production. Biocontrol News and Information, 18 2: The predatory beetle is attracted to the frass produced by its prey which contains monoterpenesand a suitable mixture of synthetic monoterpenes has been used to trap R.

Field Monitoring In the UK, surveys designed for the early detection of new infestations or for general forest health monitoring have failed to detect infestations until the beetle has been present for approximately 3 years and has become well-established.

Dendroctonus micans in the United Kingdom. The larvae produce an aggregation pheromone; a mixture of trans- and cis-verbenol, verbenone and myrtenol, which sustains larval aggregation. The great spruce bark beetle is unusual among members of its genus in that the beetles mate before they emerge from under the bark, while they are not yet fully chitinised.
