A map identifying the areas suitable for establishment of the spotted lanternfly (SLF) in the United States and other countries has been published in the Journal of Economic Entomology by Agricultural Research Service scientists. The SLF, originally from China, has spread to Korea and Japan, and has been found most recently in the United States in Pennsylvania, New Jersey, Virginia and Delaware. These insects are pests of many agricultural crops including almonds, apples, blueberries, cherries, peaches, grapes and hops as well as hardwoods such as oak, walnut and poplar, among others. USDA and State partners have been working to contain SLF populations since 2014. There is the potential for far reaching economic damage if the SLF becomes widely established in the United States.
New research from The University of Western Australia has shed light on why some invasive plants make a better comeback after a fire, outstripping native species in the race for resources.
Identifying the leading edge of an invasion can be difficult, especially when the invader is a native transplant, or if the invader is not well-known. This tool allows a user to upload a biological dataset collected anywhere in the conterminous U.S., Alaska, Hawaii, or Island Territories to screen for occurrences of non-native and invasive aquatic species tracked by the NAS Database.
The Screwworm Eradication Program Records, housed in Special Collections of the National Agricultural Library (NAL), documents one of the greatest success stories in the history of American agriculture. Led by the United States Department of Agriculture (USDA), the eradication of the screwworm from the United States, Mexico, and most of Central America marked a major victory over the destruction of domestic and wild animals by an insect which feeds only on the living tissue of warm-blooded animals.
The Screwworm Eradication Program Records document research and eradication efforts from the 1930s through 2000. These materials include correspondence, plans, reports, scientific papers and manuscripts, publications, raw research data and research analyses, livestock producer information materials and reports, cooperative agreements, photographs, maps and artifacts.
Provides contact information for State Sea Grant Programs Websites. The Sea Grant Directors lead the 33 Sea Grant programs, the National Sea Grant Law Center, and the National Sea Grant Library based at top universities in every coastal and Great Lakes state, Puerto Rico, and Guam, working to bring the robust intellectual capacity in place at these universities to bear on important societal problems. They coordinate program activities, setting local, regional and national priorities, and work as part of a national network to help citizens and businesses understand, conserve and better utilize America’s coastal, ocean and Great Lakes resources.
The Great Lakes Fishery Commission today reported that populations of the invasive, parasitic sea lamprey remain at near-historic lows, below targets, in Lakes Michigan and Ontario, and above target, but holding steady, in Lakes Huron, Superior and Erie. Sea lamprey populations in Lake Huron are close to target levels and have been holding steady for the past five years. Abundances in Lakes Superior and Erie remain above target but have also decreased significantly since the near-record highs observed in 2017. Sea lampreys are the worst of the alien species to invade the Great Lakes. Before control, sea lampreys destroyed many times the human fish catch. Today, sea lamprey control is the foundation of the $7 billion Great Lakes fishery. The Commission and its partners are encouraged by the overall decrease in abundance of sea lampreys throughout the Great Lakes basin during 2019, but caution that environmental conditions, such as a prolonged spring and high precipitation events, contributed to the decrease.
