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 or stressed trees into which they introduce fungal gardens, their sole source of nutrition.
Xyleborus glabratus, the redbay ambrosia beetle, is a type of ambrosia beetle invasive in the United States. It has been documented as the primary vector of Raffaelea lauricola, the fungus that causes laurel wilt, a disease that can kill several North American tree species in the family Lauraceae, including redbay, sassafras, and avocado.
Once a beetle chooses a tree, they release spores of this fungus along tunnels within the tree. These spores grow and eventually produce fruiting structures to be consumed by the beetles. This can allow for ambrosia beetles to indirectly feed from more tree species due to the reliance on the fungi for food and the fungi's ability to overcome ...
Xyleborus monographus, the Mediterranean oak borer, is a species of ambrosia beetle in the family Curculionidae. It is native to oaks in the regions around the Mediterranean Sea, but since 2019 has been found in California, where the oak trees it infests may be more vulnerable.
Cnestus mutilatus, commonly known as the camphor shot borer, [2] camphor shoot borer, or sweetgum ambrosia beetle, [3] is a species of ambrosia beetle in the subfamily Scolytinae of the weevil family Curculionidae. [3] It is native to Asia, but has been established as an invasive species in the United States since 1999. [4]
Xyleborus is by far the largest ambrosia beetle genus in the tribe Xyleborini, with over 500 species. [1]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.
Xyleborini are a 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.
Xyleborus affinis, the sugarcane shot-hole borer, is a species of ambrosia beetle in the family Curculionidae.It is found on all continents with woodlands and is one of the most widespread ambrosia beetles internationally, [1] primarily in areas with humid tropical climates like Florida.
