Black twig borer fact sheet
Black twig borer is native to east Asia, but is now widely distributed across nearly all tropical regions of the world including most of sub-Saharan Africa, the Americas, south-east Asia and many Pacific islands including New Guinea. It is known to be a major pest of many commercial crops including avocado, mango, macadamia, fig, lychees, coffee and cocoa. It is also known to attack a wide range of other shrubs and trees including many species of Eucalyptus, Acacia and other trees that are native to Australia and grown in plantations overseas. Black twig borers are therefore a major exotic pest threat to Australia’s forestry industry, several tree fruit industries, and to our natural environment.
