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.

How USDA & Partners Eradicated Oriental Fruit Fly from Florida

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 »

USDA’s Bay Delta Initiative Enables Landowners to Remove Insecticides from California’s Walker Creek

Water in California’s Walker Creek is now safer for residents, farmers and wildlife because of the hard work of conservationists, with funding made available through Bay Delta Initiative, (BDI), an effort of USDA’s Natural Resources Conservation Service, (NRCS).

The Bay Delta region, located in the Sacramento and San Joaquin watersheds of California, encompasses over 38 million acres and is one of the most important estuary systems in the nation. BDI helps clean and conserve water in this region as well as enhance wildlife habitat. Read more »

Helping Honey Bees’ Health

The black dot on this honey bee is a varroa mite--a parasite that sucks vital fluids like a tick, although it also acts like a mosquito transmitting viruses and other pathogens to the bee.

This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from the USDA’s rich science and research portfolio.

You’ve probably heard that the honey bees in this country are in trouble, with about one-third of our managed colonies dying off every winter. Later this week, we will learn how the honey bees survived this winter. With severe weather in a number of areas in the U.S. this winter, a number of us concerned about bees will be closely watching the results.

While scientists continue work to identify all the factors that have lead to honey bee losses, it is clear that there are biological and environmental stresses that have created a complex challenge that will take a complex, multi-faceted approach to solve.  Parasites, diseases, pesticides, narrow genetic diversity in honey bee colonies, and less access to diverse forage all play a role in colony declines.  To confront this diverse mix of challenges, we require a mix of solutions – the odds are that we won’t find one magic fix to help our honey bees.

International Researchers Mobilize Against Risky Stowaway Pests

Sometimes there is more to global trade than meets the eye. While consumers and economies may benefit from expanding market opportunities and a seemingly endless array of readily available goods, harmful pests could be lurking as people and products are transported between countries.

An international research network, including scientists from the U.S. Forest Service, has come together to share information about how exotic animals, diseases and plants can move and spread—and threaten agricultural and natural resources.

The International Pest Risk Mapping Workgroup consists of governmental and academic scientists from around the globe who study potential stowaway pests in order to assess the likelihood of their establishment in new locations and the impacts if and where they spread. Read more »

What does Maple Syrup Have in Common with an Invasive Insect?

Today is National Maple Syrup Day!  So, what does maple syrup have in common with an invasive insect?  Well, if the insect is the Asian longhorned beetle, then they both can come from maple trees.  Obviously, we want the maple syrup and not the invasive beetle.  But who cares?  And why should anyone care?  Well, I care and here’s why:

Not only do I work for the USDA’s Animal and Plant Health Inspection Service, an agency that is actively fighting known infestations of Asian longhorned beetle in three different states, but I also am a native of Vermont. Read more »
