Abstract

Insecticide sprays may provide arborists, landscapers, and regulatory officials with a useful option to control emerald ash borer (EAB) in some situations. In our 2003 studies, we found that two applications of Tempo (a pyrethroid insecticide) significantly reduced the density of EAB larvae relative to unsprayed trees. It was not clear, however, whether this control reflected mortality of adult EAB that fed on sprayed foliage or mortality of newly eclosed larvae chewing through the bark.
