First report of Phyllocoptes fructiphilus, the vector of Rose rosette virus in Florida. IFAS alert for Florida was issued by Xavier Martini, Austin Fife, Gary Knox and Mathews Paret, University of Florida. The eriophyid mite P. fructiphilus is the vector of Rose rosette virus (RRV), a lethal emaravirus identified as the causal agent of the devastating Rose Rosette Disease (RRD). In July 2019, P. fructiphilus was collected for the first time in Florida from landscape roses in Leon County from non-symptomatic roses. This new confirmation of the presence of P. fructiphilus in the landscape is critical and warrants continued monitoring of the mite in Florida. (RRD is currently not present in Florida).
