- CBB is a bark beetle native to Central Africa that is now distributed throughout coffee-producing countries around the world.
- The beetle is tiny (~2 mm long) and dark colored. Infested coffee berries have a telltale hole (sometimes two holes) visible at the blossom end of the berry. Sometimes a portion of the CBB body is visible entering into the berry.
- CBB is one of the most devastating pests of the coffee plant and is a serious economic threat to coffee growers.
- The adult female beetle bores into the coffee cherry and lays her eggs. The larvae hatch inside the cherry, grow and feed on the beans, causing damage to the quality and yield of the coffee harvest.
- Reproduction rate of this pest is very fast and they are easily transported on coffee plants, unroasted coffee beans, and harvesting equipment including coffee bags.
- CBB was confirmed on Kauai for the first time in September 2020. Several additional detections have subsequently been confirmed in the Kalaheo and Lawai area.
- It is very difficult to eradicate CBB once they have been detected. Integrated Pest Management (IPM) practices have been developed and have proven effective in helping mange population numbers and reduce damage. More information
- The public is encouraged to report any sightings of this beetle.
- To send in a suspect sample: place infected coffee beans and/or CBB into Ziplock bag. On a separate Ziplock bag, write name and address where it was found. Place the first bag into the labeled bag, seal, insert into an envelope, and mail or drop off to
