The Panel on Plant Health performed a pest categorisation of the eight-toothed spruce bark beetle,
Ips typographus L. (Coleoptera: Curculionidae, Scolytinae), for the EU. I. typographus is a well-defined
and distinguishable species, recognised mainly as a pest of spruce (Picea spp.) in Eurasia. It also
attacks other conifers such as Abies spp., Larix spp., Pinus spp. and Pseudotsuga menziesii. Native to
Eurasia, I. typographus has spread from the native range of spruce to new areas in Eurasia where
spruce has been planted, and is now widely distributed throughout the EU (22 Member states). It is a
quarantine pest listed in Annex IIB of Council Directive 2000/29/EC for Ireland and United Kingdom as
protected zones. Coniferous wood, bark and wood packaging material are considered as pathways for
the pest, which is also able to disperse by flight over tens of kilometres. The insects normally establish
on fallen trees but can also mass-attack healthy trees, killing millions of spruces. The males produce
pheromones that attract conspecifics of both sexes. Each male attracts one to four females; each
female produces 2–80 offspring. The insects also inoculate pathogenic fungi to their hosts. There are
one to three generations per year. The wide current geographic range of I. typographus suggests that
it is able to establish anywhere in the EU where its hosts are present. Sanitary thinning or clear-felling
are the major control methods. Pheromone mass trapping is presently judged unreliable because of
the large dispersal capacity of the pest. Quarantine measures are implemented to prevent entry in yet
uncolonised areas. All criteria assessed by EFSA for consideration as potential protected zone
quarantine pest are met. The criteria for considering I. typographus as a potential regulated nonquarantine
pest are not met since plants for planting are not a pathway. [-]
