The U.S. Customs and Border Protection’s (CBP) Office of Field Operations discovered 90 giant African land snails in a traveler’s luggage at Detroit Metropolitan Airport on June 30, 2024. The passenger had arrived from Ghana. The snails were seized and were “humanely euthanized,” the CBP says. The release says euthanizing the snails was necessary “to ensure they did not enter the ecosystem and cause havoc to U.S. agriculture.” 

A recent moth interception by U.S. Customs and Border Protection (CBP) agriculture specialists at Detroit Metropolitan Airport (DTW) is now considered to be the first encounter of the species since 1912.

Agriculture specialists play a vital role at our nation’s ports of entry by preventing the introduction of harmful exotic plant pests and foreign animal diseases into the United States. Learn more about how CBP agriculture specialists work in Protecting Agriculture.

To win the "Theodore Roosevelt Genius Prize Competition for Management of Invasive Species," participants must submit their technology innovation solution -- such as tools, equipment, methods, strategies, etc., that help land managers directly reduce the spread and impacts of invasive species within the United States and its Territories. Solutions should focus on invasive species that cause harm to native ecosystems. Solutions may be species-specific, but universal control techniques that may have multiple species benefits are preferred. Submission period: Open until April 30, 2022, 11:59 EDT.

The public now can help reimagine what drives wildlife conservation in the 21st century by participating in the U.S. Fish and Wildlife Service’s Theodore Roosevelt Genius Prize Competitions. The competitions will engage the public to help address six important issues: preventing wildlife poaching and trafficking, promoting wildlife conservation, managing invasive species, protecting endangered species, managing nonlethal human-wildlife conflict, and reducing human-predator conflict.

ARS scientists in Nevada, studied ways to control cheatgrass and restore rangelands to a healthy mix of plants, which in turn reduces wildfire threats, supports wildlife, and increases sustainable grazing resources.

The Chesapeake Bay Database project ended in 2020. This site will remain available for historical reference, but the database has not been updated since 2020 and will not receive any further updates. See more information in the project overview.

Chinese privet (Ligustrum sinense) is one of the worst invasive plants in the South. It dominates the shrub layer and often becomes the only shrub underneath trees, especially in streamside areas. But insects and spiders living in fallen leaves and leaf litter were not affected by a privet invasion in Georgia, as a recent study shows.

Chinese tallow tree (Triadica sebifera) is a nonnative, invasive tree whose decaying leaf litter alters water quality and the microbial community in the wetland habitats. This negatively impacts the lifecycle of semi-aquatic species like frogs.

Provides comprehensive Asian citrus pysllid and citrus greening information including: what to look for, how to prevent this disease and how it is treated. Also provides image gallery and information how to report signs of citrus disease. And provides control information including: current status, regulatory information, Huanglongbing multi-agency coordination, potentially actionable suspect sample policy, and spread the word (videos).

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. 

Contains the requirements for moving fruit, nursery stock, or other regulated articles for several citrus pests and diseases.

Rapid changes in climate and the introduction and spread of invasive species are fundamentally changing the natural and cultural landscapes of national parks. These factors have cascading effects on resource management, park operations, and visitor experience. Adapting management to continuously changing conditions requires understanding ecosystem dynamics and interactions among these global change stressors.

Evidence suggests that future climate change will further increase the likelihood of invasion of forests and rangelands by nonnative plant species that do not normally occur there (invasive plants), and that the consequences of those invasions may be magnified. Read through the synthesis for more information on the factors that influence plant invasions and how these factors interact with one another.

The brown marmorated stink bug (BMSB), Halyomorpha halys, originally from East Asia, is an invasive pest that is present throughout much of the United States. It is attracted to the outside of houses on warm fall days in search of overwintering sites and can enter houses in large numbers. The brown marmorated stink bug is also a serious economic threat to fruit crops, garden vegetables, and many ornamentals. In a changing climate, agricultural losses from insect pests like BMSB are expected to increase.

USDA ARS scientists are fighting back by developing traps, sequencing the bug’s genome, and testing parasitic wasps as biocontrols. Midwest Climate Hub research fellow, Dr. Erica Kistner-Thomas is contributing to that fight through modeling the potential distribution and abundance of BMSB under future climate scenarios using a bioclimatic niche model.
