Virus and aphid species found in strawberry crops in Argentina
The strawberry (Fragaria x ananassa Duch.) is vegetatively propagated, being the diseases caused by systemic pathogens one of the most important phytosanitary problems. More than 30 virus and phytoplasma diseases have been reported in strawberry crops worldwide. Virus-free and phytoplasma-free plants are used to control these diseases, which must be complemented with the regulation of the populations of vector insects, which are responsible of disseminating these diseases. The purpose of this review is to provide updated description of the virus and aphid species found in strawberry crops in Argentina, as a contribution to take phytosanitary actions in order to minimize the damage caused by these biotic threats. The virus species reported in Argentina are Strawberry mild yellow edge virus, Strawberry mottle virus, and Strawberry crinkle virus and Strawberry polerovirus 1, being described in this work their taxonomic and epidemiologic aspects, and their reported vectors. The aphid species found in strawberry crops in Argentina are Aphis forbesi Weed, Aphis gossypii Glover, Chaetosiphon fragaefolii (Cockerell), Chaetosiphon minor (Forbes), Chaetosiphon thomasi Hille Ris Lambers, Macrosiphum euphorbiae (Thomas), and Myzus persicae (Sulzer). Chaetosiphon species have been reported as responsible for most of the strawberry virus transmissions.
