The MSU HISL database contains a worldwide species list of Xyleborini, a major group of ambrosia beetles, from the Catalog of Scolytidae and Platypodidae of S.L. Wood and D.E. Bright (1992) A USDA-sponsored information resource and key Archived 2018-12-08 at the Wayback Machine to the world genera of Xyleborini; American Bark and Ambrosia Beetles
It has been shown that the beetle is attracted to the smell of this fungus, which may concentrate attacks on specific trees. The beetle can infest branches as small as 1.5 cm (0.6 in) across and trunks 2.5 to 6 cm (1.0 to 2.4 in) in diameter. [5] This beetle is polyphagous, infesting many species of host trees. [7]
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 trees as they attack them. Once a beetle chooses a tree, they release spores of this fungus along tunnels within the tree.
Gnathotrichus materiarius, the American utilizable wood bark beetle, is an ambrosia beetle in the family Curculionidae. [ 2 ] [ 3 ] [ 4 ] It is native to North America , [ 2 ] but has been introduced to several European countries.
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]
The beetle penetrates through thin or cracked bark in the canopy branches. [1] It first invades and kill branches in the canopy of a tree, then spreads to the trunk, culminating in the death of the tree. [2] The females produce two or more generations annually. Large populations can develop in the lower trunk over a number of growing seasons.
Platypus cylindrus, commonly known as the oak pinhole borer, is a species of ambrosia beetle in the weevil family Scolytinae. The adults and larvae burrow under the bark of mature oak trees. The adults and larvae burrow under the bark of mature oak trees.
Laurel wilt, also called laurel wilt disease, is a vascular disease that is caused by the fungus Raffaelea lauricola, [1] which is transmitted by the invasive redbay ambrosia beetle, Xyleborus glabratus. The disease affects and kills members of the laurel family. The avocado is perhaps the most commercially valuable plant affected by laurel wilt.
