Xyleborini
Xyleborini are a tribe (biology), tribe of ambrosia beetles (alternatively called subtribe Xyleborina of tribe Scolytini), highly specialized weevils of the subfamily Scolytinae. Much of the ambrosia beetle fauna in Eurasia and the Americas consists of Xyleborini species. Some Xyleborini are notorious invasive species. Most genus, genera are small or even monotypic, and contain 1-8 dozen species. The type genus ''Xyleborus (beetle), Xyleborus'' contains over 500 species, but it is an unnatural grouping of unrelated species. Key for the world genera of Xyleborini available through a North Carolina State University website.

Ambrosia Beetle
Ambrosia beetles are beetles of the weevil subfamilies Scolytinae and Platypodinae ( Coleoptera, Curculionidae), which live in nutritional symbiosis with ambrosia fungi. The beetles excavate tunnels in dead, stressed, and healthy trees in which they cultivate fungal gardens, their sole source of nutrition. After landing on a suitable tree, an ambrosia beetle excavates a tunnel in which it releases spores of its fungal symbiont. The fungus penetrates the plant's xylem tissue, extracts nutrients from it, and concentrates the nutrients on and near the surface of the beetle gallery. Ambrosia fungi are typically poor wood degraders, and instead utilize less demanding nutrients. The majority of ambrosia beetles colonize xylem (sapwood and/or heartwood) of recently dead trees, but some attack stressed trees that are still alive, and a few species attack healthy trees.Hulcr, J. and Stelinski, L.L., 2017.

Xyleborus (beetle)
''Xyleborus'' is by far the largest ambrosia beetle genus in the tribe Xyleborini, with over 500 species.MSU (2004) ''Xyleborus'' nowadays includes a number of formerly independent genera. In addition, the genera '' Coptoborus'', '' Cryptoxyleborus'' and '' Euwallacea'' are often included here, too; this may be correct, as they seem to be closely related. Less often, '' Ambrosiodmus'', '' Premnobius'' and '' Xyleborinus'' are included in ''Xyleborus'', but they seem to be well distinct; ''Premnobius'' might even not belong to the Xyleborini at all. The different species can be best differentiated by the gallery burrows they build and the tree species they infest. A significant member, '' X. dispar'', causes pear blight. Selected species * ''Xyleborus affinis'' Eichhoff, 1868 * '' Xyleborus atratus'' Eichhoff, 1875 * '' Xyleborus californicus'' Wood, 1975 - may belong in '' Cyclorhipidion'' * ''Xyleborus celsus'' Eichhoff, 1868 * ''Xyleborus cryptographus'' (Ratzeburg, 1837) * ...

Scolytinae
A bark beetle is the common name for the subfamily of beetles Scolytinae. Previously, this was considered a distinct family (Scolytidae), but is now understood to be a specialized clade of the "true weevil" family (Curculionidae). Although the term "bark beetle" refers to the fact that many species feed in the inner bark (phloem) layer of trees, the subfamily also has many species with other lifestyles, including some that bore into wood, feed in fruit and seeds, or tunnel into herbaceous plants. Well-known species are members of the type genus ''Scolytus'', namely the European elm bark beetle ''S. multistriatus'' and the large elm bark beetle ''S. scolytus'', which like the American elm bark beetle ''Hylurgopinus rufipes'', transmit Dutch elm disease fungi (''Ophiostoma''). The mountain pine beetle ''Dendroctonus ponderosae'', southern pine beetle ''Dendroctonus frontalis'', and their near relatives are major pests of conifer forests in North America.

Amasa (beetle)
Amasa (עמשא) or Amessai is a person mentioned in the Hebrew Bible. His mother was Abigail (), a sister of King David (). Hence, Amasa was a nephew of David, and cousin of Joab, David's military commander, as well as a cousin of Absalom, David's son. David calls him "my bone and my flesh" (). Amasa's father was Jether (, ) who was also called Ithra (). When Absalom rebelled against David and won over the tribes of Israel (), he appointed Amasa as commander over the army, in effect replacing Joab, who had served as commander for David. After the revolt was crushed and Absalom died (), David was invited back to Jerusalem and restored as king. David re-appointed Amasa "from now on" as his military commander () in place of Joab. The New International Version translates the Hebrew text as commander "for life". David's appointment of Amasa has been interpreted as "a bold stroke of policy, to promise the post of commander-in chief to the general of the rebel army". Kirkpatrick, A. ...
