New Tracking Technology Targets Hornets in New Zealand’s Eradication Effort

Biosecurity New Zealand is set to enhance its eradication efforts against the invasive yellow-legged hornet by introducing advanced tracking technology from the Netherlands. This new phase aims to trace hornets back to their nests, a critical step in managing their growing population in the Auckland area.

Tracking Strategy to Target Male Hornets

Recent findings revealed that more than half of the 30 queen hornets discovered on Auckland’s North Shore showed evidence of nesting. According to the Ministry for Primary Industries, the new tracking strategy will focus specifically on male hornets. North commissioner Mike Inglis explained that capturing males is essential for locating the nests.

“What happens over the next sort of four to six weeks is crucial,” Inglis said. “If we start to find males, we can put traps out to capture them. We will then attach a tracking device to the male hornet, allowing us to follow it back to its nest for destruction.” The tracking device, which features a small antenna, will enable precise tracking at various times of the day and night.

Integrated Approach to Nest Eradication

In addition to the tracking technology, Biosecurity New Zealand plans to implement a bait poison called Vespex. This product will be utilized in conjunction with protein traps, increasing the likelihood that the males will transport the bait back to their nests, ultimately leading to the eradication of the hornets.

Inglis emphasized the importance of a multi-faceted strategy that combines trapping, surveillance, and scientific guidance. “We ensure that our approach is thorough and supported by technical expertise,” he noted. This integrated method aims to combat the hornet population effectively as they begin to develop secondary nests, which are typically located in higher trees.

The public has responded positively to Biosecurity New Zealand’s efforts, with nearly 4,400 notifications regarding hornet sightings received to date. Inglis highlighted the significance of community involvement in the eradication initiative, stating, “It is important that we work together, and that public engagement remains strong.”

Tomorrow, Inglis will address a forum hosted by the Tauranga Moana Biosecurity Capital, where national experts will discuss ongoing efforts to manage the yellow-legged hornet threat. He reiterated the necessity of spreading awareness beyond Auckland, aiming to involve the entire North Island in the surveillance and reporting process.

“I have been actively communicating with Northland Council’s biosecurity team and expanding our reach to Tauranga,” Inglis added. “The response through our website and social media has been incredible, and we encourage anyone with photographs or sightings to report them.”

As Biosecurity New Zealand embarks on this crucial phase of its eradication project, the collaboration between government agencies and the public will be vital to ensuring the success of these efforts against the invasive hornet species.
