Giant Salvinia, Salvinia Molesta (Salviniaceae): Evaluation Of Sub-Optimum Temperatures On Survival Of The Giant Salvinia Weevil, Cyrtobagous Salviniae (Coleoptera: Curculionidae) And Integration Of Management Practices With Aquatic Herbicides, Lauren W. Cozad

LSU Master's Theses

Salvinia molesta is one of the world’s worst aquatic weeds and has cost Louisiana nearly $7 million worth of damage and economic impact each year. While aquatic herbicides and the biological control agent, Cyrtobagous salviniae, are the most efficacious control methods, there are limitations with each technology. Therefore, studies were conducted to evaluate insect mortality at upper and lower lethal temperatures and investigate integrated pest management (IPM) with insects and herbicides. Three Louisiana populations of C. salviniae were tested to evaluate cold tolerance and found that at 0°C, the Bayou Nicholas population was 1.3- and 1.4-times more cold tolerant …
