STEPHENSVILLE, La. (AP) - A researcher says the hard winter apparently killed much of an invasive weed that clogs waterways around Louisiana - but it also killed many of the weevils raised to fight it.
LSU AgCenter researcher Charlie Wahl says few north Louisiana landowners or agencies have asked for weevils to eat away at giant salvinia.
He says that thick mats usually form in the spring, but this year are forming in summer.
But he says the salvinia weevils he's farming and those in the wild around the state also were knocked back, and are starting to reproduce later, too.
He recently released salvinia weevils in the Big Fork Bayou area near Stephensville. But he says those take months to show effects, and landowners may need more costly herbicide.
