EENY 558: Eriophyid mite vector of Rose Rosette Disease (RRD) Phyllocoptes fructiphilus Keifer (Arachnida: Acari: Eriophyidae)

Figure 2. Feeding by the mite Phyllocoptes fructiphilus results in transfer of the virus to roses. Mites prefer to feed on tender new growth, and the virus modifies plant development to produce red foliage and stems, excessive thorniness, witches broom of shoots, and, ultimately, death. The mites are typically found in the apex of the rose shoots, where they feed and reproduce.
