Bee­tle proves costly to erad­i­cate

Co­conut rhi­noc­eros bee­tle

WHAT’S Aus­tralia have to learn about erad­i­cat­ing co­conut rhi­noc­eros bee­tle from Hawaii?

Well, ac­cord­ing Dr David Cook, a fair bit.

Co­conut rhi­noc­eros bee­tle is a large bee­tle na­tive to South-east Asia ca­pa­ble of dam­ag­ing palm species.

The bee­tle has caused se­vere dam­age to co­conut palms at Guam, de­spite con­certed ef­forts to mit­i­gate its spread, and has since been found on Honolulu at Hawaii.

Mr Cook and his team were able to ex­am­ine the spread of the pest in Guam, and then pre­dict how the bee­tle might im­pact Hawaii.

Their re­search shed some light on whether mit­i­ga­tion meth­ods were eco­nom­i­cally vi­able – erad­i­cat­ing CRB was costly as it in­volved us­ing heavy ma­chin­ery.

“We find that erad­i­ca­tion rep­re­sents a net-ben­e­fit-max­imis­ing re­sponse pro­vided the non-mar­ket (en­vi­ron­men­tal and so­cial) im­pacts of CRB ex­ceed $6.9 mil­lion per an­num,” he said.
