Invasive species may pose a significant threat to agricultural areas and/or to non-cultivated ecological systems. Being aware of these potential problem species will enable the scientific and regulatory communities to conduct proactive steps to prevent their entry or to eradicate or effectively control the species should its entry and establishment occur. Within this web site are databases identifying and providing information regarding non-indigenous arthropods that have been introduced into North America, and invasive species regulated by the Animal and Plant Health Inspection Service (APHIS):

  • Identified Plant Pests Regulated by APHIS (IPPRA) This database in comprised of insects, mites, nematodes, and plant pathogens regulated by APHIS.
  • Federal Noxious Weeds. This database contains data on invasive plants regulated by APHIS.
  • North American Non-Indigenous Arthropod Database (NANIAD) This database is focused on arthropods (insects, ticks, mites, spiders, etc.) not native to North America but have entered this region.
