November pest of the month: Brown Marmorated Stink Bug
The Brown Marmorated Stink Bug (BMSB) is an emerging concern for Australian growers. Although native to Asia and not yet established in Australia, it is often detected on imported goods and containers, before being swiftly eradicated.
Should BMSB establish a population in Australia, it would pose a significant threat to crops, plantations and amenity plants.
The pest feeds on a wide variety of crops including:
- fruit – apples, stone fruit and tomatoes
- vegetables – capsicum, eggplant, sweet corn
- legumes – soybeans
- ornamentals – orchids, magnolias, cherry and plum trees
Beyond its agricultural impact, BMSB can be a major nuisance. It often gathers in large numbers in buildings and vehicles during winter and releases an unpleasant odor when disturbed.
BMSB can resemble some native Australian stink bugs, but adults can be distinguished by the white bands on their antennae, the sides of their abdomens and legs. Early detection of this pest is crucial for effective management.
If you suspect that you have seen a BMSB, take a clear picture and report it to your states biosecurity officer or contact the Exotic Plant Pest Hotline at 1800 094 881.
If you’re facing insect infestation, you can also submit samples for identification to Grow Help Australia, a service that helps identify pests. All production nurseries in Australia are offered six free diagnostic samples each year until the end of 2025, making it easier to stay proactive.
