I was thrilled to celebrate with key partners and contributors in Napa County, California, recently at an event to recognize the critical safeguarding accomplishment we achieved together, that of eradicating the invasive European grapevine moth (EGVM) from the United States.

Leaders from the USDA, Animal and Plant Health Inspection Service (APHIS), the California Department of Food and Agriculture (CDFA), and the California County Agricultural Commissioners came together with growers and industry representatives, who found and implemented the right tools to safeguard California grapes. In front of these critical partners, I was proud to recognize the extraordinary individual and group contributions that made the eradication of EGVM possible. Read more »

As the Weather Cools, Your Firewood Choices Matter

Don't Move Firewood pests graphic

Wood boring insect pests can continue their development deep within cut wood. They can emerge from wood left to sit outside to infest new areas.

This October, the Nature Conservancy’s Don’t Move Firewood campaign and Hungry Pests, an initiative from APHIS, are partnering to present the first-ever Firewood Awareness Month. The cooler nights and quickly approaching fall season brings an increase in RV camping, hunting, and home heating. Firewood Awareness Month looks to raise public awareness about the potential danger of firewood movement as a pest and disease pathway at this high-risk time of year.

Tree-killing invasive insects and diseases can lurk both inside, and on the surface, of firewood. While these insects and diseases don’t travel far on their own, transporting firewood allows them to move hundreds of miles and start infestations in new places, explains APHIS Deputy Administrator Osama El-Lissy.

Now is a Good Time to Look for and Report Signs of Asian Longhorned Beetle Damage on Trees

To some people the smell of summer is a fresh cut grass or morning dew, but to me summer is the scent of healthy trees in full bloom.  It reminds me that summer isn’t over yet and there is still time to be outdoors.  And with August as Tree Check Month for the invasive Asian longhorned beetle (ALB), it’s a good time to take a look at your trees to make sure they are beetle free.

Last month, a homeowner on Long Island, N.Y., outside in her own yard, captured an adult beetle.  She visited the website then called the ALB hotline telephone number 1-866-702-9938 to report the beetle.  New York State’s Department of Agriculture and Marketing together with USDA’s Animal and Plant Health Inspection Service responded and collected the beetle, which was ALB.  Six infested trees were found on the property.

Saving Florida’s Citrus Industry Through Collaboration and Innovation

Thermotherapy trucks cover infected citrus trees with a canopy to heat treat them significantly reducing the amount of disease in the trees and increasing their productivity.

The Florida citrus industry is under siege and the invader is a tiny bug called the Asian citrus psyllid (ACP).  The ACP spreads a disease known as Huanglongbing (HLB) or citrus greening, and together they are destroying groves that have been cultivated by families for generations.

But all is not lost.  USDA’s Animal and Plant Health Inspection Service (APHIS) is working closely with State and Federal partners such as the Agricultural Research Service and National Institute of Food and Agriculture, as well as State departments of agriculture and the citrus industry in Florida, California, Arizona and Texas to develop short-term solutions to help protect groves while researchers focus on longer-term projects that may one day put an end to this devastating pest and disease combo.

The Very Hungry Caterpillar is Real, and It’s More Than Just a Nuisance

While being outside in Massachusetts this June, I first noticed it.  A lot of leaves were falling from the trees, only these were chewed leaf parts, not whole leaves.

Similar to the children’s book, The Very Hungry Caterpillar written by Eric Carle, some leaves didn’t just have chew marks but actual holes going straight through them.  Unlike the children’s book, this damage isn’t being caused by a friendly caterpillar who turns into a butterfly.  Instead it’s the result of ravenous gypsy moth caterpillars feeding…and feeding.  It’s so bad that in some areas, on walkways and roadways, it looks like fall.  Brown, dried up leaves are a contrast to summer’s lush greenery.

Rabies and Vampire Bats

All this month we will be taking a look at what a changing climate means to Agriculture. For APHIS, changes in environmental conditions will increase the likelihood of shifts in the distribution and nature of current domestic diseases, invasive species and agricultural pests.  These changes will likely influence the dynamics of invasion and establishment of these diseases and pests, and therefore much of APHIS’ work. Understanding and adapting to these changes is therefore critical to meeting our mission.

Vampire bats rank high on the list of animals that scare us the most. Spooky Halloween tales of their blood-sucking, nocturnal, and secretive habits have likely led to their bad reputation. The fact that some also carry and spread the deadly rabies virus doesn’t help.

The common vampire bat feeds on the blood of Central and South American wildlife and livestock. They also sometimes bite and feed on the blood of people. Recently, vampire bats have been documented within 35 miles of the Texas border. This has caused concern and speculation about the potential movement of vampire bats to areas within the United States as a result of rising global temperatures. To gain a better understanding of the likelihood of such movement, USDA-APHIS geneticist Dr. Toni Piaggio with the Wildlife Services National Wildlife Research Center partnered with U.S. Geological Survey scientist Dr. Mark Hayes to analyze and map the potential distribution of vampire bats under various climate scenarios.
