The first infestation of the coffee berry borer in the Kau district of the Big Island has been detected at a farm in Pahala, state agricultural officials announced today.

Infestations of the beetle, which threaten Hawaii’s $27 million coffee-growing industry, have been concentrated in West Hawaii.

The coffee berry borer, a small beetle native to Central Africa, bores into coffee beans and lays its eggs, its larvae feeding inside the bean.

State officials said they’re still assessing the extent of the infestation in Pahala and that farmers in the region are asked to inspect their fields and report any suspected coffee berry borers.

The state in February approved the use of the fungus Beauveria bassiana to control the spread of the coffee berry borer.
