ITP and the APHIS PPQ S&T Beltsville Lab are pleased to announce the release of IDphy: Molecular and Morphological Identification of Phytopthora Based on the Types, ITP’s first pathogen tool. This website offers PPQ and its partners the most complete, valid, and up-to-date resource for identifying the culturable species of Phytophthora. IDphy includes detailed standard operating procedures for all steps involved in culturing, sequencing, and identifying suspect samples, covering both molecular and morphological methods. Some species of Phytophthora are devastating plant pathogens that have a significant impact on agriculture and natural ecosystems.

Over the last year, MAISRC research teams have worked tirelessly in the field, lab, and at their computers to generate and analyze data that is informing evidence-based decisions from the end of your dock to the State Capitol. The incremental steps are making a difference, leading to big wins, and eventually to real-world solutions to aquatic invasive species problems. MAISRC is sharing past year's research highlights in the form of a story map—enjoy an interactive experience, watch project videos, click straight to project pages, and see exactly where research is happening on the map.

The United States Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) has analyzed the potential environmental impacts of releasing a parasitoid wasp to biologically control the Russian wheat aphid. The Russian wheat aphid is a wingless, pale yellow-green or gray-green insect lightly dusted with white wax powder that feeds and develops on grass and cereal species. The biological control agent is a small, stingless wasp called Aphelinus hordei that can be used to reduce the severity of damage caused by Russian wheat aphids. Based on our assessment and other relevant data, releasing this biological control agent will not have a significant impact on the quality of the human environment. APHIS invites the public to review and comment on the environmental assessment until June 4, 2020, 30 days after publication in the Federal Register on May 5, 2020.

The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) is awarding $566,626 to support four new cooperative agreements with tribal partners through the National Animal Disease Preparedness and Response Program (NADPRP). These projects will enhance these Tribes’ – and our nation’s - animal disease response capabilities and strengthen APHIS’ relationships with these partners.

USDA’s Animal and Plant Health Inspection Service (APHIS) is replacing the common name for regulated Lymantria moths. APHIS will replace "gypsy moth" (Lymantria dispar) with "spongy moth" and "Asian gypsy moth" (L. dispar asiatica, L. dispar japonica, L. albescens, L. postalba, and L. umbrosa) with "flighted spongy moth complex." This change aligns APHIS with the Entomological Society of America’s "Better Common Names Project" and the scientific community. Spongy moths are significant invasive forest pests. They can defoliate hundreds of species of trees and shrubs and harm our country’s natural resources.

The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) is continuing to advance animal disease preparedness and response through its Farm Bill animal health programs. APHIS is seeking project proposals for the National Animal Disease Preparedness and Response Program (NADPRP) and the National Animal Health Laboratory Network (NAHLN). The agency is also announcing its next round of purchases for the National Animal Vaccine and Veterinary Countermeasures Bank (NAVVCB). The 2018 Farm Bill provided funding for these programs as part of an overall strategy to help prevent animal pests and diseases from entering the United States and reduce the spread and impact of potential disease incursions through advance planning and preparedness. Projects selected for funding will be awarded in FY 2024.

APHIS will make available up to $23.5 million in funds for NADPRP and NAHLN. NADPRP proposals must be submitted by October 20, 2023, and NAHLN proposals must be submitted by October 27, 2023.

In response to the increasing damage and disease threats posed by expanding feral swine populations in the U.S. , Congress appropriated funds to APHIS in 2014 to create a collaborative National Feral Swine Damage Management Program. Congress continues to allocate funds annually to support the program. The program’s overarching goal is to protect agricultural and natural resources, property, animal health, and human health and safety by managing feral swine damage. APHIS collaborates with many stakeholders—including States, Tribes, other Federal agencies, universities, and the public—to accomplish this goal.

Effective November 16, 2021, the Animal and Plant Health Inspection Service (APHIS) and the California Department of Food and Agriculture (CDFA) established a Mediterranean fruit fly (Medfly) quarantine area in San Bernardino and Los Angeles Counties, California. APHIS is applying safeguarding measures and restrictions on the interstate movement or entry into foreign trade of regulated articles from this area. This action is in response to the CDFA’s confirmation of a mature, unmated female Medfly on October 25, and a subsequently confirmed male Medfly on November 9 from Jackson traps placed in backyard citrus trees in residential areas of Upland, California. There are 15.75 acres of commercial agricultural production in the quarantine area. Currently, the quarantine area encompasses 95 square miles.

Effective immediately, the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS), in cooperation with the Michigan Department of Agriculture and Rural Development (MDARD), is expanding the quarantine for the box tree moth (BTM, Cydalima perspectalis) to include all of Clinton, Eaton, Ingham, Jackson, Livingston, Monroe, Oakland, and Wayne Counties in Michigan.

The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) is announcing the implementation of Phase VII of the Lacey Act provisions. APHIS is finalizing the associated declaration requirement required by Congress for plant and wood products. In this phase, declarations will be required for all remaining plant product Harmonized Tariff Schedule (HTS) codes that are not 100-percent composite materials. Implementation of Phase VII will begin December 1, 2024.

If an importer imports items that contain plant products, but do not currently file a Lacey Act declaration, they likely will need to file under Phase VII. Phase VII includes the broadest range of items, items as varied as industrial or medicinal plants, handbags, plywood, laminated wood, tools, matches with natural wood stems, products of natural cork, products of bamboo and rattan, footwear and more. Plant and wood products included in past phases include timber, some furniture, essential oils, wood cases and trunks, and woodwind instruments and their parts and accessories.

Effective immediately, the Animal and Plant Health Inspection Service (APHIS) is modifying the conditions under which citrus fruit may be moved interstate from areas quarantined for sweet orange scab (SOS) when destined for processing or packing in a commercial citrus-producing state without a state-wide SOS quarantine.

USDA's Plant Protection and Quarantine (PPQ) continuously takes steps to enhance our ability to exclude, control, and eradicate pests and increase the safety of agricultural trade. Across the country, PPQ worked with the States and other partners to detect, contain, and when possible, eradicate invading pests. On the world stage, PPQ worked closely with our international trading partners to develop and promote science-based standards, helping to create a safe, fair, and predictable agricultural trade system that minimizes the spread of invasive plant pests and diseases. Learn about the many successes and accomplishments captured in the 2018 report (APHIS 81-05-021) and how PPQ is working every day to keep U.S. agriculture healthy and profitable.
