Brown mulberry longhorn beetle is not present in Australia but is widespread in the Asian region. It only feeds on living trees (but these may be healthy or stressed) and its potential effect on Australian native plants is not known.
The beetle is most likely to arrive in imported timber and wood used for pallets, or other packing materials from Asia. Look out for larval tunnels in the wood up to 15 mm wide, sawdust-like frass falling from damaged timber, and oval-shaped exit holes. Diligence is particularly essential with imported material from India and China where it has been reported as a major pest of mulberry and poplar plantations.
In Australia, many woody species within the Moraceae, Salicaceae and Ulmaceae families may be affected, including elm, fig, mulberry, poplar, pear, citrus, rosewood, hawthorn, lagerstroemia, mulberry, walnut, and willow, as well as other tree species. More
