Gov. Bobby Jindal, state legislators and ConAgra Food officials thanked the LSU AgCenter during the Nov. 5 grand opening of ConAgra’s new sweet potato processing plant near Delhi.
The nutria is possibly the most well-known of the non-native species introduced into the environment of south Louisiana.
These articles were published in the fall 2010 issue of Louisiana Agriculture Magazine.
Because of the persistent infestation of the Formosan subterranean termite that has threatened to destroy historical buildings in the French Quarter of New Orleans, a federally funded program called Operation Full Stop was initiated in 1998 to apply areawide treatments to suppress the termite and limit further damage.
The red imported fire ant invaded the United States from South America more than 75 years ago. It was first discovered in Louisiana in the early 1950s.

For the past few months, the institutions of higher education in Louisiana, including the LSU AgCenter, have been under the threat of deep budget cuts as high as 32 percent. Such severe cuts would be catastrophic.
Solving the whodunit mystery of insect damage in a rice crop will be easier with a new online program developed by the LSU AgCenter.
There is an invasive species in town that might not be welcome, but at least this one we would like to invite to dinner. Commercial fishers across Louisiana have been reporting increasing populations of both bighead carp and silver carp, known collectively as Asian carp, beginning in the early 1980s.
I remember watching a science fiction television program as a child where the residents of a house were being attacked by giant termites the size of small cars from an alien world.
Asian carp have become a huge environmental problem in waterways throughout the Mississippi and Missouri river basins.These fish, which are comprised of the “silver” and “bighead” species, were originally introduced into private U.S. ponds in the 1970s.
Since the arrival of Europeans in North America, thousands of plants have been introduced intentionally for agricultural, fiber or ornamental purposes.
An unintended consequence of the Deepwater Horizon oil spill, which occurred on April 20, 2010, has been the expansion of invasive freshwater plants into the intertidal zone along Louisiana’s Gulf Coast.
Experts estimate the damage from Formosan subterranean termite infestations in the United States exceeds $1 billion per year. In Louisiana alone, the most affected state in the continental United States, they estimate damage at almost $500 million a year.
From an entomology integrated pest management perspective, invasive species have several characteristics that make them difficult to control. As the insect is brought in or migrates into new areas, only rarely does the new pest bring along its natural enemies, which can include parasites, predators and diseases.
The LSU AgCenter has released three new varieties of rice.
Red imported fire ants were introduced into the United States more than 75 years ago. Since then, fire ants have invaded more than 320 million acres in 12 southeastern states, and they continue to spread despite eradication and quarantine efforts.
Plants and animals introduced into Louisiana cause a wide range of ecological problems. Notable examples include water hyacinth, Chinese tallow tree, nutria, English sparrows and European starlings.
