Laboratory rearing of emerald ash borer

The emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), native to several Asian countries, was identified in 2002 as the cause of ash (Fraxinus spp.) mortality throughout southeastern Michigan and southwestern Ontario. More isolated infestations continue to be found throughout Lower Michigan, northern Ohio, Maryland, and Virginia, resulting from transport of infested host materials. An eradication plan is being developed for EAB as this invasive pest threatens ash resources throughout North America. Collaborative research among researchers in Michigan on EAB biology, control, detection, dispersal, host range, and natural enemies required large numbers of healthy insects for bioassay and other experimental treatments.
