The Ongoing Search for New Biological Control Agents of Hydrilla

Hydrilla verticillata, or hydrilla, is a submersed aquatic plant native to Asia, Australia, Europe, and Africa. It is one of the world’s worst weeds. It is a federally listed noxious weed in the U.S. and, after its introduction in the early 1950s, has become widely distributed and highly invasive...more 

Lab Spotlight: Australian Biological Control Laboratory (ABCL)

Australian Biological Control Laboratory (ABCL) staff actively search the natural areas of Australia and Southeast Asia for insects and other organisms that feed on plant species and pest insects that are invasive in the U.S...more  

EBCL Works on Sustainable Solutions for Integrated Management in the U.S. of Invasive Pests from Europe, Asia and Africa

The mission of the European Biological Control Laboratory (EBCL) is to develop classical biological control methodologies as well as strategies to control blood feeding insects and ticks (vectors) to sustainably suppress insect and tick pests originating in Europe, Asia, and Africa. This is in direct response to the pests’ adverse impacts on agriculture, human health, and wildlife in the U.S...more

Finding Biocontrol Agents for French Broom, Medusahead and Tree-of-Heaven

Since 1919, the European Biological Control Laboratory (EBCL) played a crucial role collecting and providing research and candidate biological control agents to federal and state cooperators for the management of invasive weeds...more

Finding Natural Enemies for Little Fire Ants

One of Foundation for the Study of Invasive Species (FuEDEI)’s main projects, the little fire ant (Wasmannia auropunctata; LFA), is an invasive ant native to South America. The LFA has become a major agricultural problem in Hawaii, and a spreading invader in the continental U.S...more

Researching New Biocontrol Agents for Water Hyacinth

Physiological studies can provide valuable information to ensure the success of a biocontrol agent. For instance, the relationship between herbivores and their host plants often involves a mutual dependency (symbiotic associations) with different microorganisms, often called endosymbionts...more

Determining the Distribution, Source Population, and Natural Enemy Complex of the Roseau Cane Scale in China

Roseau cane or common reed (Phragmites spp.) is the dominant plant species and a critical component of the Mississippi River Delta in Louisiana. The community of Phragmites in the Mississippi River Delta is made up of different varieties, which together protect the marsh ecosystem from erosion and storm-related impacts, maintaining shipping channels and oil infrastructure...more
