Abstract: 

Invasive species are becoming an increasing problem and pose a challenge to policy and management. When faced with an invasive species, it is difficult to balance quick action to control or eradicate the species with research and monitoring to determine how problematic the species will be and the effects of treatment. California is currently facing an emerging invasive species problem with the detection of Epiphyas postvittana, commonly called the light brown apple moth (LBAM), in 2006. California has declared to eradicate LBAM because it is a general feeder that could pose a threat to the economically important agricultural and horticultural industries in California. This study looks at the moth populations and diversity at Stanford University's Jasper Ridge Biological Preserve (JRBP), evaluating the potential impacts on the preserve of LBAM establishment and treatment against LBAM. The study found no LBAM currently at the preserve but found related moths, concluding the LBAM treatments are likely to be more harmful to the moth populations and ecosystems at JRBP than the establishment of LBAM at the preserve. California has dealt with invasive insects before, notably the Mediterranean fruit fly, Ceratitis capitata, and appears to be using less environmentally harmful methods to handle LBAM than were used to handle the medfly. The state needs to ensure that exemptions are provided for biological preserves, however, to protect the research and diversity they house from unnecessary harm.
