LIHU‘E — The state Department of Agriculture and University of Hawai‘i personnel will update Kaua‘i residents on the status of coffee berry borer and coffee leaf rust during an online “mini-conference” on Wednesday, Oct. 13, from 10 a.m. to noon.

Berry borers (Hypothenemus hampei) are beetles, and rust (Hemileia vastatrix) is a fungus. Both are threats to the state’s coffee-growing operations.

The conference is free via Zoom. The tentative agenda’s topics include identification and biology; a status report and discussion of the pests’ island-wide distribution; and integrated pest management. A question-and-answer period will follow.

The CBB was first reported in the state 10 years ago, but was not seen on Kaua‘i until September 2020. CLR is a more-recent and transmissible threat. It was discovered in a Kilauea coffee orchard July 2021 after sweeping through the other major Hawaiian islands.

Attendees can register online at https://bit.ly/3C7MAZd. The registration window closes at 1 p.m. on Tuesday, Oct. 12.
