The coffee berry borer was detected in December 2016 on a coffee farm in Kīpahulu on Maui.
A neighbor of the 13-acre farm reported the possible CBB infestation to an extension agent at the University of Hawaiʻi, College of Tropical Agriculture and Human Resources on Maui.
Entomologists at the Hawaiʻi Department of Agriculture confirmed that it was CBB, a serious pest of coffee that was first detected in the state in Kona in 2010.
UH-CTAHR reports that the entire farm has been found to be infested with CBB, which indicates the infestation has been there for some time.
Earlier in November 2016, a resident in Hāna contacted HDOA about CBB in two backyard coffee trees. Those backyard trees were stripped of all coffee berries and fallen cherries have been collected and frozen to kill CBB. HDOA continues to monitor CBB traps at that site. Although the Kīpahulu farm and the Hāna residence are about 12 miles apart; it is not known if the two infestations are related.
HDOA surveys have been conducted in West Maui, ʻĪao Valley and Waikapū, and CBB has not been been detected in those areas.
HDOA’s Plant Quarantine Branch is also working on expanding quarantine protocol for movement of coffee plants and plant parts from Maui to uninfested areas.
“Despite strict quarantine rules that have been established on the interisland movement of coffee plants and plant parts from Hawaiʻi Island, CBB infestations have been extremely difficult to contain,” said Scott Enright, chairperson of the Hawaiʻi Board of Agriculture. “We ask that coffee growers continue to be vigilant and learn about CBB and how infestations can be detected and managed.”
