Pathways of non-indigenous plant pest introductions: How exotic insects, pathogens and weeds arrive in the United States

Principal Investigators:

Deborah G. McCullough, Joseph F. Cavey, and Sarah Reichard

Non-indigenous weeds, phytophagous insects and plant pathogens have had dramatic effects on ecosystems in North America and threaten nearly half of all endangered species in the United States. Introductions of non-indigenous species are expected to continue and will likely increase as global trade expands. The U.S. Department of Agriculture, Animal and Plant Health Inspection Service (USDA, APHIS) is responsible for excluding non-indigenous phytophagous insects, plant pathogens and noxious weeds. Since 1985, APHIS personnel have maintained a database... more
