Abstract

Nearly all Fraser fir (Abies fraseri) Christmas trees produced in North Carolina need to be treated one or more times during their 5- to 10-year rotation to prevent or lessen damage caused by the exotic balsam woolly adelgid (BWA) (Adelges piceae Ratz.). These pesticide applications result in an annual cost to the industry estimated at $US 1.53 million not including direct losses due to BWA damage or increased miticide control costs associated with BWA treatments. A BWA resistance screening trial was established in a greenhouse at the Upper Mountain Research Station in Ashe County, NC.
