Biological Control in Pest Management Systems of Plants (FY 2002)
Hoary cresses (Cardaria spp.) are exotic invasive cruciferous plant species that spread at fast rates in the western United States and cause ecological and economical problems. This project studies the genetics and ecology of hoary cresses, and the effects of plant competition and herbivory. The information will facilitate the selection of host-specific natural enemies with the greatest control potential at an early stage of a biological control program, which will be used in an overall integrated pest management strategy for these species.
