A gypsy moth caterpillar on a leaf in Massachusetts
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. Read more »
The streamlined design of Oobinator 2.0 improved the distribution of the wasps—each Oobinator containes 50 wasps that could be positioned at four distinct locations throughout the field site. Stingless wasps disperse in the field to search for EAB eggs that will serve as a host for its offspring.
Emerald ash borer (EAB) beetle is an invasive wood boring beetle, first detected in July 2002 in southeastern Michigan. The pest attacks and kills ash trees and it is responsible for the death and decline of tens of millions of ash in 25 states. EAB lives under the bark and when people move EAB-infested firewood they unknowingly move the pest. During EAB Awareness Week (May 22-28) leave HungryPests behind and don’t move firewood.
Do you remember the eighties television show MacGyver? Science genius turns secret agent. Each week Angus MacGyver—armed with only a pen, aerosol spray can and a Swiss Army knife—successfully disarms the bomb and saves the day! The following week, it’s a shoe horn, jumper cables and a screwdriver…then a thermos, belt buckle….you get the drift. Sixty minutes of ingenious, nail-biting problem-solving.
Although the show’s final episode aired almost 25 years ago, the spirit of Angus lives on at the USDA’s Emerald Ash Borer (EAB) biological control production facility, where USDA is strategically rearing natural enemies to combat this destructive pest. Mass rearing biocontrol agents (stingless wasps) is a delicate process that’s time-sensitive, labor-intensive, and laden with problem-solving opportunities. Read more »

There’s a good reason why USDA and the Florida Department of Agriculture and Consumer Services (FDACS) constantly monitor more than 56,000 fruit fly traps they have strategically placed across Florida. An outbreak of exotic fruit flies—one of the most destructive pests of fruit and vegetables—could threaten Florida’s powerhouse agricultural industry. By detecting these pests early and responding rapidly, USDA, FDACS, county officials, and growers can avoid large-scale agricultural losses and keep valuable export markets open.
In August 2015, some of those traps captured Oriental fruit flies (OFF) in Miami-Dade County.
The OFF attacks more than 430 different fruits, vegetables, and nuts, including avocado, mango, guava, papaya, and pitaya. All of these crops and more grow in the county, which is Florida’s top producer of tropical fruit, tropical vegetables, and ornamental nurseries. The county’s $1.6 billion agricultural industry supports 11,000 jobs. Read more »
The Asian Longhorned Beetle has killed more than 100,000 trees since it was accidentally introduced to this country about 20 years ago.
USDA APHIS is deeply involved with mitigating invasive pest issues, along with State and local governments. Invasive pests cost the U.S. an estimated $120 billion each year in damages to our environment, agriculture, and native species. The five invasive species described here are a few of the damaging invasive pests of concern to the Animal and Plant Health Inspection Service. You can help detect these pests and take actions to reduce their spread. Read more »

Forest Action Plans represent the first-ever comprehensive assessment of America’s forest resources across all lands—public, private, rural, and urban—and offer proactive strategies that state forestry agencies use to conserve, protect and enhance the trees and forests we depend on.
The Forest Action Plans are invaluable at a time when tree mortality is on the rise due to disease and invasive pests; wildfires continue to increase in size and intensity; and forests are being permanently converted to non-forest uses at a rate of one million acres per year. These assessments help state forestry agencies employ a variety of tools for protecting and conserving forests and the benefits they provide to people, from quarantines related to invasive species, to practices to reduce hazardous fuels buildup, to enhanced landowner outreach and education on sound forestry practices.

Last year, an invasive pest known as the spotted lanternfly was found in the United States for the first time ever in Berks County, Pennsylvania. Tucked away in Pennsylvania Dutch Country, Berks County may seem an unlikely location to find a foreign pest, but with today’s global economy unwanted pests can show up almost anywhere.
In response, the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) is working closely with the Pennsylvania Department of Agriculture (PDA) to stop this pest from spreading. APHIS has already contributed more than $1 million in Farm Bill funding to support the response effort in Pennsylvania, and PDA quickly established a quarantine area and regulated the movement of potential host material to help protect other communities.
