Interpretive Summary:

Technical Abstract: The soybean aphid, Aphis glycines, has been reported to transmit several viruses in Asia, however, it does not transmit the Asian strains of the Soybean dwarf luteovirus (SbDV), that are specifically transmitted by Aulacorthum solani. Since its first discovery in the United States in 2000, the soybean aphid has been shown to transmit Soybean mosaic virus but not field isolates of SbDV found in Illinois. We compared the transmission of several eastern U.S. isolates of SbDV by Acyrthosiphon pisum, (pea aphid), Myzus persicae, (green peach aphid), and A. glycines. At this time, we have confirmed the transmission of two indigenous SbDV isolates by A. glycines through symptomatology (mild rugosity and leaf curling in soybean and leaf reddening in subterranean clover), positive ELISAs with antisera to SbDV, positive PCR products using primers developed from published SbDV sequences, and subsequent transmission from these plants by A. pisum and M. persicae. This is the first report of the soybean aphid transmitting U.S. isolates of SbDV.
