Starting Wednesday, Feb. 25, coffee grown in all areas of Oahu will be placed under the same quarantine restrictions as coffee grown in Waialua on Oahu and Hawaii Island.

The Hawaii Board of Agriculture voted unanimously to expand the designated infested area and extend the interisland quarantine restrictions to prevent the spread of the coffee berry borer.

On Dec. 17, 2014, HBOA placed coffee grown at Waialua Estate Coffee Farms and coffee roasted at the Old Waialua Sugar Mill under the same quarantine restrictions as coffee grown on Hawaii Island due to the detection of CBB infestations at those sites.

Since the initial detections in Waialua, CBB has been found in Wahiawa and Poamoho in Central Oahu.

“Expanding the coffee quarantine safeguards to cover Oahu is an important step in helping to keep other coffee-growing islands free of the coffee berry borer,” said Scott Enright, chairperson of the HBOA. “Oahu is a hub for the state’s coffee trade and we need to make sure that coffee beans that are imported to, as well as exported from Oahu are not spreading this destructive pest.”

So far, CBB has not been detected on Maui, Kauai, Molokai and Lanai.

The quarantine restrictions imposed today for Oahu are exactly the same as those which have been in effect for coffee from Hawaii Island since December 2010.

It requires a permit from HDOA to transport unroasted coffee beans, coffee plants and plant parts, used coffee bags and coffee harvesting equipment from CBB-infested islands to other non-infested areas or islands to prevent CBB movement.

The rules also require certain treatments and inspection by HDOA Plant Quarantine inspectors prior to shipping. Inspectors will either attach a tag, label or stamp to indicate the shipment passed inspection requirements.

For unroasted coffee beans, acceptable treatment protocols include fumigation, freezing and heat treatment. The coffee beans must also be roasted at a facility that is at least five miles from any commercial coffee-growing area.

One of the most devastating coffee pests, CBB was first detected in the state in September 2010 in Kona and discovered in Kau in May 2011. In early December 2014, HDOA confirmed the presence of the CBB (Hypothenemus hampei) on the coffee farm in Waialua, Oahu.

This small beetle bores into the coffee “cherry” to lay its eggs. The larvae feed on the coffee bean, reducing the yield and quality of the bean. CBB is native to Central Africa and is also found in many coffee-growing regions of the world, including Central and South America.

Since its detection in Kona in 2010, Big Island coffee growers have developed methods to manage the pest, which include using an organic pesticide and field sanitation practices. Some farms with good management practices have been able to keep infestations down to about 20 percent of the coffee crop.
