There are a number of ambrosia beetle species or whole groups that display restricted host choice, but it usually has a biogeographic twist. For example, Xyleborus glabratus is exclusively found in Lauraceae in North America where it is an invasive species, but no such specificity was reported from its native SE Asia. Euwallacea fornicatus, on the other hand, seems to be mostly interested in Artocarpus in Asia, but no such specificity in the invaded regions of USA and Israel. There are many genera specialized on Dipterocarpaceae or Fagaceae, for example Webbia or Cryptoxyleborus from Xyleborini, or Genyocerus from Platypodinae (Beaver & Liu, 2007). Camptocerus species (Scolytini) are specialized to Protium species in the Neotropics. Even more host specific are the few ambrosia beetle species that attack live trees. For example, Austroplatypus incompertus, an eusocial platypodine colonizes only live Eucalyptus trees (Smith et al., 2009). Xyleborus vochysiaecan be found in live Vochysia sp. in Costa Rica, and nowhere else (Kirkendall, 2006).
