Coffee Berry Borer Infestation
Coffee berry borer (Hypothenemus hampei), the most harmful beetle to the arabica coffee crop was discovered in Kona coast plantations in September 2010 by a graduate student of the University of Hawaii. How the tiny beetle got to Kona is unknown, but the size of the infestation indicates it has been going for a few years. Some growers suspected severe drought conditions had reduced the fungus Beauveria bassiana, which might have kept the beetle population under control for years.
By late November 2010, the Hawaii Department of Agriculture declared a quarantine on all green (unroasted) beans leaving the island. Fumigation with a chemical such as methyl bromide or a six-step procedure was required. The price of Kona coffee was expected to rise, up to a possible $50 per pound by December 2010, if the infestation lingers or spreads, because the insect has the potential to reduce crop yields up to 90%. In early 2011 the Hawaii State Dept. of Agriculture allowed the import and application of a concentrated naturally occurring fungus (beauveria bassiana) to successfully combat the infestation.
