Gallery of Xylosandrus crassiusculus split open, with pupae and black fungus. Until recently ambrosia beetles have been placed in independent families Scolytidae and Platypodidae, however, they are in fact some of the most highly derived weevils, and are now placed in the subfamilies Scolytinae and Platypodinae of Family Curculionidae [4] [5] [6] There are about 3,000 known beetle species ...
This beetle is native to Asia, and has spread to other parts of the world as an invasive species in Africa, the Americas, Europe and Oceania. [5] It was first reported in the southeastern United States in 1974, had reached Costa Rica by 1996, Panama by 2003, and Guatemala and northern Brazil by 2008.
Although unnamed Ambrosiella-like fungi had previously been documented from the galleries and mycangia of native X. crassiusculus populations in central Japan, [1] A. roeperi was first described as a novel species of ambrosia fungus by Harrington and McNew in 2014 based on isolations from beetles collected and trapped in the eastern United States, where it is invasive.

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.
Some bark beetles form a symbiotic relationship with certain Ophiostomatales fungi, and are named "ambrosia beetles". The ambrosia beetles (such as Xyleborus) feed on fungal "gardens" cultivated on woody tissue within the tree. Ambrosia beetles carry the fungal spores in either their gut or special structures, called mycangia, and infect the ...
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]
Xylosandrus compactus is a species of ambrosia beetle. Common names for this beetle include black twig borer, black coffee borer, black coffee twig borer and tea stem borer. The adult beetle is dark brown or black and inconspicuous; it bores into a twig of a host plant and lays its eggs, and the larvae create further tunnels through the plant ...
Like other species of ambrosia beetles, X. saxesenii has a mutualistic relationship with ambrosia fungus species. [6] This beetle is associated with several fungal species, but its interactions are primarily known to be with the Raffaelea sulfurea species. [5] X. saxesenii, like other ambrosia beetles, create tunnels in the trees of which they ...
