Egg and larval cohorts of emerald ash borer, Agrilus planipennis, were established on healthy ash trees in 2008 and their survival or mortality rate were assessed the following year. While egg and larval mortality due to parasitism were low (<1%), predation and host plant resistance appeared to inflict high mortality of EAB eggs and early instar larvae.
