Species Profile -- Spiny Water Flea
USDA. NAL. National Invasive Species Information Center.
Spiny water fleas are small predacious crustaceans that threaten aquatic ecosystems and fishing by competing with native fish for food and fouling gear. Water flea introductions have decreased growth or survival rates for many fish, particularly young plankton feeders.

Species Profile -- Asian Citrus Psyllid
USDA. NAL. National Invasive Species Information Center.
The Asian citrus psyllid (ACP) is a pest that acts as a carrier or vector spreading Citrus Greening, a devastating disease of citrus trees. This bacterial disease is transmitted to healthy trees by the psyllid after it feeds on infected plant tissue.

West Nile's North American Spread Described (Nov 6, 2008)
ScienceDaily.
The rapid spread of West Nile virus in North America over the past decade is likely to have long-lasting ecological consequences throughout the continent, according to an article in the November issue of BioScience. The mosquito-borne virus, which was little known before its emergence in New York in 1999, has since been found in all 48 contiguous states.

Species Profile -- Citrus Greening
USDA. NAL. National Invasive Species Information Center.
Huanglongbing (HLB), also known as Citrus Greening Disease, is a bacterial plant disease that – while not harmful to human health – destroys the production, appearance and economic value of citrus trees and the taste of the fruit and juice. It is the most serious citrus plant disease in the world and once a tree is infected, there is no cure. Diseased trees produce bitter, inedible, misshapen fruit and eventually die.

Federal Interagency Committee on Invasive Terrestrial Animals and Pathogens (ITAP)
ITAP.gov.
ITAP is the Federal Interagency Committee on Invasive Terrestrial Animals and Pathogens. ITAP's mission is to support and facilitate more efficient networking and sharing of technical information for program planning and coordination among Federal Agencies and Departments involved with invasive species research and management. ITAP focuses on several major taxonomic groups of invasive species for which improved technical coordination is essential to facilitate effective Federal responses. ITAP's mission parallels and complements the missions of the Federal Interagency Committee for the Management of Noxious and Exotic Weeds (FICMNEW) and the Aquatic Nuisance Species Task Force (ANSTF).

Lacey Act
USDA. Animal and Plant Health Inspection Service.
The 2008 Farm Bill (the Food, Conservation, and Energy Act of 2008 (PDF | 1.4 MB ), effective May 22, 2008, ammended the Lacy Act.
