Remarks
In March 2005, a large infestation of the delphacid planthopper, Liburnia pseudoseminigra (Muir & Gifford), was found infesting St. Augustinegrass, Stenotaphrum secundatum, in a commercial sod farm in southern Florida. (Cherry et al. 2006)
Large population numbers can create nuisance problems.
