Biosecurity Alert: Invasive Brown Marmorated Stink Bug Detected in New Zealand

Early Detection Crucial to Prevent Agricultural Damage

The Ministry for Primary Industries (MPI) has issued a biosecurity alert after the Brown Marmorated Stink Bug (BMSB) was detected in Auckland and Tauranga. This invasive pest poses a significant threat to New Zealand's horticulture and agricultural industries, and early detection is crucial to prevent widespread damage.

What is the Brown Marmorated Stink Bug?

The BMSB is a small, shield-shaped bug native to Asia. It is known for its distinctive brown and white marbled pattern and emits a pungent odor when disturbed. BMSB feeds on a wide range of fruits, vegetables, and ornamental plants, causing severe damage to crops and reducing yields.

How Did the BMSB Enter New Zealand?

The BMSB is believed to have arrived in New Zealand through imported goods or international travel. It is a highly mobile pest that can spread rapidly through natural dispersal or human activity. The detection of BMSB in two separate locations suggests multiple introductions or an established population.

Potential Impact on New Zealand's Agriculture

The BMSB is a major concern for New Zealand's horticulture industry, which exports billions of dollars worth of fruit and vegetables annually. The bug's voracious feeding habits can cause significant economic losses due to reduced crop quality, increased production costs, and potential market restrictions.

In addition to horticulture, the BMSB also poses a threat to other agricultural sectors, such as viticulture, forestry, and pastoral farming. The bug can damage grapevines, reducing wine production and quality. It can also feed on pine trees, affecting the timber industry.

Biosecurity Measures and Response

MPI is implementing a range of biosecurity measures to contain and eradicate the BMSB. These measures include increased surveillance and monitoring, public awareness campaigns, and the deployment of biosecurity officers in affected areas.

The public is urged to report any sightings of BMSB to MPI immediately. Members of the horticulture and agriculture industries are encouraged to implement biosecurity practices on their properties to prevent the spread of the pest.

Conclusion

The detection of the Brown Marmorated Stink Bug in New Zealand is a serious biosecurity threat. Early detection and rapid response are essential to prevent widespread damage to our horticulture and agricultural industries. By working together, we can protect New Zealand's biosecurity and safeguard our valuable agricultural sector.
