I-Emerald ash borer (EAB), Agrilus planipennis Fairmaire, nguqongqothwane ongaqhelekanga owafunyanwa kumzantsi-mpuma weMichigan kufuphi naseDetroit ngehlobo lika-2002. Ooqongqothwane abadala badla amahlamvu othuthu kodwa benza umonakalo omncinane. Imibungu (inqanaba elingekavuthwa) itya ixolo elingaphakathi lemithi yothuthu, nto leyo ephazamisa ukukwazi komthi ukuthutha amanzi kunye nezondlo.
I-Emerald ash borer mhlawumbi yafika e-United States inezinto zokupakisha iinkuni eziluqilima ezithwalwa kwiinqanawa zemithwalo okanye iinqwelomoya ezisuka eAsia. I-Emerald Ash Borer ikwasekwe kwamanye amazwe alishumi elinesibini nakwiindawo zaseCanada. Ngelixa i-Emeral Ash Borer ingekabiyingxaki eCalifornia, isenokuba kwixa elizayo.
Ngomzamo wokufundisa abantu malunga nemiphumo ye-Emeral Ash Borer, i-USDA Forest Service, iYunivesithi yaseMichigan State, iYunivesithi yaseOhio State, kunye neYunivesithi yasePerdue baye baqulunqa uluhlu lweewebinars zamahhala ezibizwa ngokuba yi-Emerald Ash Borer University. Kukho iiwebinars ezintandathu ukusuka ngoFebruwari ukuya ku-Epreli. Ukubhalisa, tyelela i Iwebhusayithi yeEmerald Ash Borer. Ngenkqubo ye-EABU, abantu baseCaliforni banokulungiselelwa izinambuzane kwaye bafunde iindlela zokujongana nezinye iintlobo ezingaqhelekanga njengeGoldspotted Oak Borer.
