  • APHIS Establishes an Oriental Fruit Fly (Bactrocera dorsalis) Quarantine in Santa Clara County, California

    • Nov 5, 2021
    • USDA. Animal and Plant Health Inspection Service.

    • Effective September 30, 2021, the Animal and Plant Health Inspection Service (APHIS) and the California Department of Food and Agriculture (CDFA) established an Oriental fruit fly (Bactrocera dorsalis or OFF) quarantine in the San Jose area of Santa Clara County, California. This action is in response to the confirmed detections of six adult male OFF from the San Jose area by CDFA between September 13 and September 24, all from traps in various types of fruit trees in residential areas. By October 4, CDFA confirmed the seventh male OFF in the vicinity of the earlier finds, which expanded the quarantine further. The establishment of this quarantine area is reflected on the APHIS website, which contains a description of all current Federal fruit fly quarantine areas.

  • USDA Provides more than $70 Million in Fiscal Year 2021 to Protect Agriculture and Natural Resources from Plant Pests and Diseases

    • USDA. Animal and Plant Health Inspection Service.

    • The U.S. Department of Agriculture (USDA) is allocating more than $70 million to support 383 projects under the Plant Protection Act’s Section 7721 program to strengthen the nation’s infrastructure for pest detection and surveillance, identification, threat mitigation, to safeguard the nursery production system and to respond to plant pest emergencies. Universities, states, federal agencies, nongovernmental organizations, nonprofits, and Tribal organizations will carry out selected projects in 49 states, the District of Columbia, Guam, and Puerto Rico.

      The fiscal year 2021 project list includes 29 projects funded through the National Clean Plant Network (NCPN). The NCPN helps our country maintain the infrastructure necessary to ensure that pathogen-free, disease-free and pest-free certified planting materials for fruit trees, grapes, berries, citrus, hops, sweet potatoes, and roses are available to U.S. specialty crop producers. In FY 2021, funded projects include, among others:

      • Asian giant hornet research and eradication efforts: $944,116 in Washington and other states;
      • Exotic fruit fly survey and detection: $5,575,000 in Florida and California;
      • Agriculture detector dog teams: $4,287,097 to programs in California, Florida, and nationally to support detector dog teams;
      • Honey bee and pollinator health: $1,337,819 to protect honey bees, bumble bees and other important pollinators from harmful pests;
      • Phytophthora ramorum (sudden oak death pathogen) and related species: $513,497 in 14 states and nationally for survey, diagnostics, mitigation, probability modeling, genetic analysis, and outreach;

      USDA will use $14 million to rapidly respond to invasive pest emergencies should a pest of high economic consequence be found in the United States. Learn more about the Plant Protection Act, Section 7721 on the USDA Animal and Plant Health Inspection Service (APHIS) website.
