Abstract
We cannot definitely list Orthosia hibisci Guenée as an annual pest of hybrid poplar trees in Oregon and Washington. However, a major defoliation of older trees due to this pest in 2005 lead to an application of diflubenzuron (Del Pozo-Valdivia 2011) in May 2006 to target early instars. In 2008, we captured over 300,000 O. hibisci male moths with just one baited sex pheromone per 160 acres (65 hectares). After five years (2006–2011) of monitoring O. hibisci populations, we know that their numbers do increase within each planting as poplar trees age, and growers have a valid concern about their potential to defoliate trees. Our objective is to provide professional integrated pest management (IPM) managers with: a means to identify O. hibisci, a way of monitoring their numbers, and a means to control the population if necessary.
