Ant Lab Wins Conservation Award

The Hawai‘i Department of Land and Resources reports that the Hawai‘i Ant Lab has won the 2018 Conservation Innovation Award by the Hawai‘i Conservation Alliance. The Ant Lab is a collaboration of the University of Hawai‘i’s Pacific Cooperative Studies Unit and the Hawai‘i Department of Agriculture, and was established in response to the Little Fire Ant (LFA) invasion.

When the LFA was discovered on Hawai‘i Island in the late 1990s, it could have been the beginning of the end for much of Hawai‘i’s agriculture and our remaining native ecosystems. Twenty years later, the impacts of the ant have been undeniably substantial: residents on the eastern side of Hawai‘i Island have seen their homes and businesses invaded, tourists visiting beach parks have taken home unexpected welts from ant stings, and the ant has found its way in interisland cargo to Kaua‘i, O‘ahu and Maui.

The Ant Lab has produced several innovations to meet these challenges, with one of the first being a new gel bait that can be applied to tree canopies and other vertical structures. The effort has brought the world’s foremost experts on the species to the lab’s headquarters in Hilo. On Hawai‘i Island, the lab works to assist farmers, nurserymen, and residents with LFA management and to slow the spread of the ant as much as possible across the island. The lab also works with the Department of Agriculture to minimize the movement of ants in interisland cargo, and leads both prevention and control projects across the Pacific.

On Kaua‘i, the Ant Lab and partners have rappelled over cliffs on the north shore to remove the sole infestation in Kalihiwai, which is on track for eradication. On O‘ahu, the team partnered with agencies to remove ants from Mililani Mauka after a population was discovered in December 2013. The area was recently declared free of LFA. In Waimanalo, the Ant Lab provides guidance and support to the Department of Agriculture and other partners to remove ants that may be moving in potted plants. On Maui, several small populations have been removed and the team is working with the Maui Invasive Species Committee to design a strategy that will hopefully eradicated the large Nahiku infestation.

“Little Fire Ants remain a serious concern for Hawai‘i, and many residents and business owners are struggling with the impacts of this invasive species” said Suzanne Case, chairperson of the Department of Land and Natural Resources and co-chair of the Hawai‘i Invasive Species Council. “Without the excellent work of the Hawai‘i Ant Lab, it’s possible that we would have dense, intractable populations of Little Fire Ants on all of the main islands by now.”

“Little Fire Ants have the potential to impact everyone,” Heather Forester, extension specialist at the Hawai‘i Ant Lab said. “Unfortunately, as humans we are more reactive than proactive, but if you focus your efforts on surveying your property and high-risk materials you bring onto your property, you have the chance to stop Little Fire Ants from establishing. For those of us who have Little Fire Ants, there is hope to manage this invasive; it just takes diligence and follow-through.”

The impacts of the LFAt are diverse and threaten our agriculture, tourism, environment, human health, and quality of life. On Hawai‘i Island alone, the ant is estimated to cause approximately $174 million a year in damages. The innovations of the Hawai‘i Ant Lab have helped Hawai‘i maintain its goals of growing more local food and protect a tourism industry valued at over $15 billion annually.

October is “Spot the Ant, Stop the Ant” Month, during which residents are encouraged to test their yards and workplaces for the presence of Little Fire Ant.
