Oak Ambrosia beetle

Platypus quercivorus

Oak Ambrosia beetle (Platypus quercivorus) is an insect pest.

Platypus quercivorus, a wood boring ambrosia beetle, is considered a significant pest of oaks in Japan. Raffaelea quercivora, an ambrosia fungus closely associated with and vectored by P. quercivorus, is associated with Japanese oak disease. Recent studies have shown that the cause of oak tree mortality is the blockage of the ascent of sap induced by the fungus which is transmitted by the insect. This is just one of many forest pests that are moved to un-infested forests by humans moving firewood. Help to protect our forests: don't move firewood!
