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

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. |
