Tiny creatures being bred inside a double-wide greenhouse 465 feet from Caddo Lake are about to take the next bite out of the giant salvinia weed that’s threatened the state’s largest natural lake since 2006.

“We’re going from research to high production,” said Darren Hudson, president of Greater Caddo Lake Association, while standing amid 10 low-lying tanks filled with the invasive salvinia in the Morley Hudson Weevil Greenouse at Caddo Lake.

The plant, native to Brazil but arriving here like a floral cousin to fire ants or killer bees, grew bright green and unmolested in some of those the ankle-high tanks. Others held salvinia under attack by its only known natural predator, the giant salvinia weevil.
