Invasive Species - What's New on NISIC's Site

National Pollinator Week (June 17-23, 2024) is a time to celebrate pollinators and spread the word about what you can do to protect them. In 2007, the U.S. Senate’s unanimous approval and designation of a week in June as “National Pollinator Week” marked a necessary step toward addressing the urgent issue of declining pollinator populations. 

Pollinator Week 2024 is a celebration of the vital role that pollinators play in our ecosystems, economies, and agriculture. Under the inspiring theme "Vision 2040: Thriving ecosystems, economies, and agriculture," this year's event urges us to envision a future where pollinators not only survive but thrive. These essential creatures, including bees, butterflies, moths, bats, beetles, and hummingbirds, are the unsung heroes behind the food we enjoy and the beauty that surrounds us.

Currently, most cogongrass is controlled with herbicides, which only serve as a temporary solution. The herbicides must be reapplied every 6-12 months. ARS scientists in the U.S. and overseas are investigating biological control of cogongrass by collecting and studying insects that feed on the grass where the weed originated. These insects will be screened over many years to determine if they will be safe, and only those that cause no harm to valued plants will be released.

For more than 30 years, the U.S. Fish and Wildlife Service has worked with Vermont and New York to control this invasive species and protect Lake Champlain. Fortunately, sea lamprey woundings are now at an all-time low.

The U.S. Department of Agriculture today announced it is taking several additional actions to ensure the health and viability of the nation’s livestock and poultry. In the two months since the initial detection of H5N1 in dairy cattle, USDA has worked quickly and in concert with its federal and state partners to better understand the virus and contain the disease and remains committed to seeking additional ways to collect the data needed to better understand and mitigate the risk created by this outbreak.

Lady beetles are one of the most effective, natural ways to control crop-damaging pests such as aphids. A single lady beetle can devour hundreds of aphids in its lifetime, thereby curbing the need for pesticides. Unfortunately, some lady beetles native to the U.S. and Canada are dwindling in numbers. ARS scientists are studying their declining populations.

Aquatic invasive species cause tremendous harm to our environment, our economy, and our health. They can drive out and eat native plants and wildlife, spread diseases, and damage infrastructure. The U.S. spends billions of dollars every year to manage and control these aquatic invaders and protect the nation's waters. Although prevention is the most effective approach to eliminate or reduce the threat of aquatic invasive species,  Early Detection and Rapid Response (EDRR)  serves as a failsafe when prevention measures are ineffective or unavailable.

Recognizing the need for action, the U.S. Department of the Interior identified advancing a National EDRR Framework for invasive species as a priority for Bipartisan Infrastructure Law funding and took steps to invest in supporting components of such a framework. One such critical component was the establishment of a pilot Rapid Response Fund for Aquatic Invasive Species that can be used to assess and support response actions for quick containment or eradication of newly detected species.

Boxwood blight is a fungal disease that can cause the leaves of boxwood plants to fall off prematurely. ARS scientists in Fort Dietrick, MD, are studying how boxwood blight evolves and are working closely with the floriculture and nursey industry to develop methods for testing, controlling, and mitigating the disease.

Seed banks can provide insight into a forest’s past and give land managers valuable information to help them plan for the forest’s future. For example, knowing which species may germinate after future fires is valuable, especially when nonnative invasive species in the seed bank could proliferate quickly following disturbances.

In this study, researchers analyzed the species composition of buried seeds and extant vegetation present in areas that have faced differing fire conditions over many years on the Monongahela National Forest in West Virginia.

This portal shares information about how ARS research is combating the disease that is devastating the citrus industry and provides information for the general public, as well as points of contact for those seeking more specialized answers.

Huanglongbing, also known as citrus greening, poses the most serious threat that the Florida citrus industry has ever faced. ARS scientists across the country are actively engaged in research with university and industry partners on all aspects of this disease problem, including the host, pathogen, and insect vector. Our goal is to overcome citrus greening and ensure the U.S. citrus industry can provide consumers with tasty, high quality citrus fruits for years to come. 

The newly launched Vermont Forest Invasive Pest Status Map offers an interactive platform to track the spread of invasive species such as beech leaf disease, elm zigzag sawfly, elongate hemlock scale, emerald ash borer, and hemlock woolly adelgid across the state. The application provides users with a comprehensive overview of town infestations and detection years for each invasive pest.
