Although the Brown marmorated stink bug (BMSB) is considered an exotic pest that has not established itself in Australia, it remains a threat to our agricultural industries.

Detections generally increase between September and April in Australia when temperatures are favourable for their survival and reproduction. Continued monitoring during these months remains crucial to swiftly identify and manage any potential incursions.

With BMSB season underway, Plant Health Australia (PHA) has refreshed its factsheet to reflect the latest advice from the Department of Agriculture, Fisheries, and Forestry (DAFF).

The factsheet provides growers, producers, biosecurity officers, and Members with up-to-date information on identifying BMSB. The updated factsheet includes tips for on-farm protection.

While several stink bug species in Australia may look similar, adult BMSB have distinctive black and white banding around the edge of the abdomen with white bands on the last two antennal segments. The DAFF website provides further details on how to tell them apart from native species.

Since we have experienced a particularly wet season, it is especially important be on the lookout for BMSB. DAFF expects seasonal monitoring and prevention methods for the BMSB to continue until the end of April.

If you see anything unusual, report it immediately by calling the Exotic Plant Pest Hotline on 1800 084 881.
