The Light Brown Apple Moth (LBAM) is an important invasive pest for California, and has become established throughout much of California’s central coast.  It is a regulated pest in ornamental and fruit crops important to the central coast economy.  The University of California Cooperative Extension (UCCE) in Santa Cruz County conducts research in Santa Cruz and Monterey counties to aid in LBAM detection and management.  UCCE has been trapping LBAM in and around wholesale nurseries, apples, and berries since 2009.
