Study Confirms Invasive Lionfish Now Threaten Species Along Brazilian Coast (Jun 3, 2021)
California Academy of Sciences.

Since arriving to the northern Atlantic Ocean less than 30 years ago, lionfish have quickly become one of the most widespread and voracious invasive species, negatively impacting marine ecosystems—particularly coral reefs—from the northeast coast of the United States to the Caribbean Islands. In a new study, an international research team including the California Academy of Sciences presents four new records of lionfish off the coast of Brazil, confirming the invasion of the predatory fish into the South Atlantic for the first time.

APHIS Expands the European Cherry Fruit Fly (Rhagoletis cerasi) Quarantine to include all of Monroe and Wayne Counties, New York (May 28, 2021)
USDA. Animal and Plant Health Inspection Service.

Effective May 11, 2021, the Animal and Plant Health Inspection Service (APHIS) and the New York State Department of Agriculture and Markets (NYS AGM) expanded the European cherry fruit fly (ECFF) quarantine to include all of Monroe County and Wayne County and a small portion of northwestern Ontario County, New York. With this expansion, the ECFF quarantine now includes all of Erie, Monroe, Niagara, Orleans, and Wayne Counties. This action is necessary to prevent the spread of ECFF to non-infested areas of the United States, while maintaining commercial cherry production and marketing within the state. The APHIS website reflects the expansion of this quarantine and contains a description of all the current federal fruit fly quarantine areas.

USDA Announces 2021 Plans for Asian Longhorned Beetle Eradication Efforts in Massachusetts, New York, Ohio and South Carolina (Jun 3, 2021)
USDA. Animal and Plant Health Inspection Service.

The U.S. Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) is announcing its plans for combatting the Asian longhorned beetle (ALB) in Massachusetts, New York, Ohio, and South Carolina in 2021. "Every year, APHIS evaluates and determines the most effective options to achieve ALB eradication," said Osama El-Lissy, APHIS' Plant Protection and Quarantine Deputy Administrator. "Complete eradication of this pest from the United States remains our goal, and our strategy this year will advance our efforts to eliminate this pest from where it is infesting trees."

In 2021, the ALB program will focus on inspecting trees in quarantined areas in Massachusetts, New York, Ohio, and South Carolina, and removing infested trees at no cost to property owners. The program will not apply insecticide treatments this year. Program officials will monitor for the beetle's presence inside and around each area, respond to calls for assistance, conduct training sessions for compliance agreement holders, and perform outreach.

Climate Change Fans Spread of Pests and Threatens Plants and Crops, New FAO Study (Jun 2, 2021)
UN. Food and Agriculture Organization.

Due to the impact of climate change, plant pests that ravage economically important crops are becoming more destructive and posing an increasing threat to food security and the environment, finds a scientific review released this week. The Scientific Review on the Impact of Climate Change on Plant Pests - A global challenge to prevent and mitigate plant pest risks in agriculture, forestry and ecosystems was prepared under the auspices of the Secretariat of the International Plant Protection Convention and is one of the key initiatives of the International Year of Plant Health, which is coming to an end this month. "The key findings of this review should alert all of us on how climate change may affect how infectious, distributed and severe pests can become around the world," said the Director-General of the Food and Agriculture Organization of the United Nations (FAO), Qu Dongyu. "The review clearly shows that the impact of climate change is one of the greatest challenges the plant health community is facing," added Qu.

California Invasive Species Action Week (Jun 5-13, 2021)
California Department of Fish and Wildlife.

The goals of the California Invasive Species Action Week (CISAW) are to increase public awareness of invasive species issues and promote public participation in the fight against California's invasive species and their impacts on our natural resources.

Prevention is the most effective strategy in managing invasive species. However, hundreds of invasive plants and animals have already established in California and are rapidly spreading each year. These invaders are negatively impacting our waters, our native plants and animals (some of them rare, threatened, or endangered), our agriculture, our health, our economy, and our favorite recreational places. Help us celebrate California's Invasive Species Action Week, and more importantly, help stop the spread of invasive species, by volunteering to take action.

Share your lunch hour with Cal-IPC and the University of California Cooperative Extension to learn how invasive species are affecting California, with our Invasive Species Week Lunchtime Talks -- June 7-11, 2021. Webinars are part of California Invasive Species Action Week, organized by the California Department of Fish & Wildlife. Webinars are free, but you must register in advance.

APHIS Adds Del Norte County in California to Phytophthora ramorum Quarantine Area (May 21, 2021)
USDA. Animal and Plant Health Inspection Service.

Effective immediately, the Animal and Plant Health Inspection Service (APHIS) is expanding the Phytophthora ramorum (P. ramorum) quarantine area in Del Norte County, California. APHIS is taking this action in response to the confirmation of P. ramorum in the county on September 19, 2020. The California Department of Food and Agriculture has established an intrastate quarantine for the areas in Del Norte County that mirrors the federal regulatory requirements as specified in 7 CFR 301.92.

P. ramorum is the pathogen that causes sudden oak death, ramorum leaf blight, or ramorum dieback. Sudden oak death was first reported in 1995 on tan oak in Mill Valley, Marin County, California. Through ongoing surveys, APHIS continues to define the extent of the pathogen's distribution in the United States and uses quarantine areas and public outreach to limit its artificial spread beyond infected areas. Details on APHIS-designated P. ramorum quarantine and regulated areas and the conditions to move regulated articles are in 7 CFR 301.92 and at the APHIS website.

USDA Expands the Federal Quarantine Area for Asian Longhorned Beetle in South Carolina (May 21, 2021)
USDA. Animal and Plant Health Inspection Service.

Effective immediately, the U.S. Department of Agriculture's Animal and Plant Health Inspection Service (APHIS), together with South Carolina Clemson University's Department of Plant Industry (DPI), is adding portions of Charleston and Dorchester Counties to the quarantine area for the Asian longhorned beetle (ALB) in South Carolina. This action is being taken in response to the detection of two infested trees found earlier this year just outside of the current quarantine area.

If you live in the quarantine area, please help by allowing officials access to your property to inspect and remove trees. If you live in Charleston County, Dorchester County, or nearby counties, please look for ALB and examine your trees for any damage that may be caused by the beetle, such as dime-sized exit holes in tree trunks and branches. Please take pictures and, if possible, capture suspicious insects in a durable container and freeze them, which helps to preserve the insects for identification. ALB is not harmful to people or pets. Report the insect or tree damage by calling the ALB hotline at 1-866-702-9938 or submitting a report online at www.AsianLonghornedBeetle.com.

Invasive Alien Species Cost Africa's Agricultural Sector an Estimated USD $3.6 Trillion a Year (May 20, 2021)
CAB International.

CABI scientists have conducted the first comprehensive study on the economic impact of a range of Invasive Alien Species (IAS) on Africa's agricultural sector, which they estimated to be USD $3.6 trillion a year. This is equivalent to 1.5 times the Gross Domestic Product (GDP) of all African countries combined – or similar to that of Germany. The average annual cost of IAS per country was USD $76.32 billion. Full details of the cost for individual countries are outlined in the paper published in the journal CABI Agriculture and Bioscience.
