The threat of brown marmorated stink bug (BMSB) is escalating in Australia, with six new detections thus far in the 2018/19 season. Key months of heightened risk of entry of BMSB to Australia are from September to April, as the bugs overwinter on cargo and in containers, coinciding with late autumn and winter in the Northern Hemisphere.

The Department of Agriculture and Water Resources (DAWR) has introduced measures to manage the risk of BMSB during the high risk season for these pests. Some of these measures, including increased scrutiny on imported goods, with delays at ports due to treatment and clearance requirements, have impacted Australian wine businesses.

BMSB is a threat to the wine and grape industries as it has the potential to damage grapes and taint wine. Importantly, it can also cause significant public nuisance.

The six new post-border detections of live and dead BMSB have occurred since September 2018 across Australia; in Queensland, Victoria and Western Australia on a variety of imported cargo. The affected goods have been subject to biosecurity control and fumigation, and surveillance is now underway to determine that these bugs have been contained.
