| Abstract: | DAS-ELISA was used to study the presence of viruses in four aphid species ( Aphis gossypii , Aphis craccivora , Myzus persicae and Macrosiphum euphorbiae ) and in their host plants potato, capsicum and tomato. Samples were collected in different regions in Tunisia: north, Cap Bon, Sahel, centre and south. A. gossypii and M. persicae carried all the viruses detected: Cucumber mosaic cucumovirus , Tomato aspermy cucumovirus , Tobacco etch potyvirus , Potato Y potyvirus , Alfalfa mosaic alfamovirus and Potato leafroll polerovirus . These two aphids were also those that occurred most frequently on the crops concerned. |
