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.
