A coffee berry borer beetle is threatening Kona coffee crops

Kona Coffee Berry Borer Beetle


Kona Coffee is at risk as the coffee berry borer beetle destroys coffee crops!


Kona Coffee crops at at a unique risk from a new African pest known locally on the Big Island at the "Berry Borer Beetle". Here are some facts you didn't know about this Kona coffee pest:

The coffee berry borer (Hypothenemus hampei) is a pest that has caused about a half a billion dollars damage to the world’s coffee crop each year. This includes gourmet coffees such as Kona coffee and other Hawaii coffee.

  • Overall the coffee industry overall generates about $90 billion each year. The coffee berry borer beetle is a tiny insect that is native to the African continent.
  • The coffee berry borer beetle lays eggs in the coffee fruit of the plant which is known as the coffee cherry. This is a little red fruit that the Kona coffee bean is extracted from.
  • The eggs in the coffee berry and fruit develop into larva. These larva then feed on the coffee bean inside that berry.
  • Once the coffee berry borer beetle invades the fruit of a Kona coffee plant it may cause secondary infestation of other things like fungi, bacteria and other insects.
  • The damage caused by the coffee berry borer as well as the secondary effects can destroy the Kona coffee beans
  • The beetle reduces the yield of the Kona coffee trees on a Kona coffee farm or plantation.
  • The coffee berry borer beetle infesting a Kona coffee plant will typically drill into the Kona coffee cherry and within one or two days will lay about three or four dozen eggs.
  • Coffee berry borer beetles are about 1.5 mm long. Females can fly a short ways but the males do not have wings.
  • The larval stage of the coffee berry borer beetle lasts about two and one-half weeks.
  • It takes about thirty-four days from the time that a egg is laid by the coffee berry borer to the time the insect reaches adulthood.
  • Female coffee berry borer beetles live about 110 days while the males only live about forty days.
  • One infested Kona coffee plant could potentially contain several generations of the coffee berry borer beetle.
