Investigations on the vector transmission of the Beet mild yellowing virus (BMYV) and the Turnip yellows virus (TuYV)

Abstract: The ability of 24 aphid species to transmit the Beet mild yellowing virus (BMYV) from beet to beet and the Turnip yellows virus (TuYV) from oilseed rape to oilseed rape was tested. Virus infections of test plants were detected by DAS-ELISA 8 weeks after inoculation. The main vector of both viruses was Myzus persicae with transmission rates of 96,4 % for TuYV and 28,6 % for BMYV. A vector of both viruses with less efficiency was furthermore Macrosiphum euphorbiae (8,9 % and 1,8 %, respectively).
New vectors detected for the TuYVwere Brachycorynella asparagi, Cavariella aegopodii, Macrosiphoniella sanborni, Macrosiphum albifrons, Myzus nicotianae, Nasonovia ribisnigri, Pentatrichopus fragaefolii, Rhopalosiphum maidis and Sitobion avenae. The TuYV isolate used in the experiments was transmitted also by Acyrthosiphon pisum (green race), Aphis gossypii, Aulacorthum circumflexum, Aulacorthum solani, Brevicoryne brassicae, and Rhopalosiphum padi. The transmission rates by these species were distinctly lower than for M. persicae but higher than the transmission rates for BMYV. As further. vectors of BMYV only Aphis fabae were found. The observed differences for the vectors and transmission efficiency are additional points that the differences between TuYV and BMYV are greater than accepted till now.
