Based on years of experience and the latest science, APHIS developed a list of 59 pests and diseases that could pose a significant risk to U.S. food and agriculture resources. The list is not meant to be all-encompassing, but rather focus on the most impactful pests and diseases. USDA's goal remains to keep the U.S. free of these foreign pests and diseases and those posing a significant risk to U.S. food and agriculture resources. Section 12203 of the 2018 Farm Bill requires pest- and disease-planning activities that mirror the extensive planning efforts APHIS already performs. Specifically, it requires APHIS to develop a uniform list of pests and diseases that represent the gravest threat to the U.S. and to develop comprehensive response plans to ensure Federal and State governments are prepared to respond to them.

APHIS created the webpage to make it easier for its customers to find critical information on pests and diseases of concern. With this tool, members of the public will have the information they need to report pests and diseases and together we can protect America’s agriculture and natural resources. This page lists all pest and disease programs managed by APHISas part of its mission to protect American agriculture and natural resources. Users can search by type (plant, animal), keyword (avian, fruit fly, cotton), or by the specific pest or disease (coconut rhinoceros beetle, brucellosis). You can also scroll through the page, which lists the pests and diseases alphabetically and includes a corresponding image.

Cal-NEMO provides comprehensive information on introduced marine and estuarine invertebrates and algae in California. The database contains everything from brief overviews of species and taxonomic groups to detailed records on the history of spread. The creation of NEMESIS and Cal-NEMO has involved years of research and literature review, and remains an ongoing project. Records are updated as new species are reported and new research is available.

The Chesapeake Bay Database project ended in 2020. This site will remain available for historical reference, but the database has not been updated since 2020 and will not receive any further updates. See more information in the project overview. For up to date information on introduced marine and estuarine invertebrates and algae in Chesapeake Bay, please visit the NEMESIS North American database.

The APHIS Federal Noxious Weed Program is designed to prevent the introduction into the United States of nonindigenous invasive plants.

Provides fact sheets, maps and collection information for aquatic vertebrates and invertebrates occurring outside of their native range.

The United States Register of Introduced and Invasive Species ( US-RIIS ) serves as a national inventory for all non-native and invasive species that are established (naturally reproducing) within three localities of the United States: Alaska, Hawaii, and the conterminous (or lower 48) United States.

APHIS regulates the following list of pests under the authority of the Plant Protection Act. It does not include any 'regulated non-quarantine pests' (pests which are present and may be widely distributed in the U.S.

Introduced (non-native) species that becomes established may eventually become invasive, so tracking introduced species provides a baseline for effective modeling of species trends and interactions, geospatially and temporally.

The United States Register of Introduced and Invasive Species (US-RIIS) is comprised of three lists, one each for Alaska, Hawaii, and the conterminous United States. Each list includes introduced (non-native), established (reproducing) taxa that: are, or may become, invasive (harmful) in the locality; are not known to be harmful there; and/or have been used for biological control in the locality.

To be included in the US-RIIS, a taxon must be non-native everywhere in the locality and established (reproducing) anywhere in the locality. Native pest species are not included. The US-RIIS builds on a previous dataset, A Comprehensive List of Non-Native Species Established in Three Major Regions of the U.S.: Version 3.0 (Simpson et al., 2020).
