Capacity assessment of Myzus persicae, Aphis gossypii and Aphis spiraecola (Hemiptera: Aphididae) to acquire and retain PVYNTN in Tunisia

Zusammenfassung:The study was carried out to investigate the ability of three aphids, Myzus persicae, Aphis gossypii and Aphis spiraecola , to acquire and retain the Potato Virus Y (PVY) isolate, PVY NTN . Tobacco plants, Nicotiana tabacum var. Xanthi, were used as test plant for the virus inoculation and aphid acquisition. The serological test double-antibody sandwich enzyme-linked immunosorbent assay was applied for virus detection on the test plants and aphids. Furthermore, virus retention by aphids was also assessed using a monoclonal anti-PVY N . Although a duration of 2 min was enough for the virus acquisition, the three tested aphids showed different capacities to retain PVY NTN . The retention of PVY NTN was 3 h for M. persicae and A. spiraecola , and 2 h for A. gossypii . This study provides basic information of the virus retention by potato-colonizing aphid species, which may increase our understanding of PVY epidemiology in Tunisia.
