“…More mixed infections were found in 1990 when incidence of PMV was generally higher than in 1991. Mixed infections of PMV and PSV (14) and PMV and PStV (8,15,19) have also been reported in peanut in the United States. We found a few plants that were doubly infected with PMV and PSV or with PSV and TSWV, but we did not identify PStV in any sample tested in this or a previous survey of peanuts in Alabama.…”

Leaf samples collected from 1,883 peanut plants in 158 fields in 14 counties during July- August, 1990 and 1991, were tested for peanut mottle (PMV), peanut stripe (PStV), peanut stunt (PSV), and tomato spotted wilt (TSWV) viruses by sap inoculations onto indicator plants and/or by enzyme-linked immunosorbent assay (ELISA). Of 889 plants showing virus-like symptoms, 58% were infected with TSWV alone or mixed with PMV or PSV, 36% with PMV alone or mixed with TSWV or PSV, and 5% with PSV alone or mixed with TSWV or PMV. Double infections of PMV with TSWV, PSVwith TSWV, and PMVwith PSVwere detected in 24%,3%, and 1% of the symptomatic plants. Of 994 apparent asymptomatic plants, 16% were infected with PMV alone or mixed with TSWV, 8% with TSWV alone or mixed with PMV or PSV, and 5% with PSV alone or mixed with TSWV. Double infections of PMV with TSWV and PSVwith TSWVwere detected in 2% and 1%of the asymptomatic plants. PMV and TSWV were found in at least one field in every county sometime during the two seasons; PSV was found in 13 counties. The most notable difference in virus incidence betWeen the two years was that TSWV was found in 20% of the asymptomatic plants in 1990 as compared to 6% in 1991. PStV was not detected by ELISA in 1990 or 1991, and no reactions suggestive of PStV or any virus other than PMV, PSV, or TSWV were observed on indicator plants used to assay the 1990 collections.

“…The transmission efficiency was low, but did not differ from that from singly infected plants. In addition, in studies on Peanut mottle virus (PeMV) and Peanut stripe virus (PStV), both potyviruses, simultaneous transmission of the two viruses by single aphids from double‐infected to healthy assay plants was very poor with M. persicae , and absent with Aphis craccivora Koch (Sreenivasulu and Demski, ). In the same study, a low rate ( M. persicae ) or failure ( A. craccivora ) of transmission was also recorded when individual aphids acquired PeMV and PStV during sequential feeding on singly infected peanut plants.…”

Viruses are likely to be the most dangerous parasites of living organisms because of their widespread occurrence, possible deleterious effects on their hosts and high rates of evolution. Virus host-to-host transmission is a critical step in the virus life cycle, because it enables survival in a given environment and efficient dissemination. As hosts of plant viruses are not mobile, these pathogens have adopted diverse transmission strategies involving various vector organisms, mainly arthropods, nematodes, fungi and protists. In nature, plants are often infected with more than one virus at a time, thereby creating potential sources for vectors to acquire and transmit simultaneously two or more viruses. Simultaneous transmission can result in multiple infections of new host plants, which become subsequent potential sources of the viruses, thus enhancing the spread of the diseases caused by these pathogens. Moreover, it can contribute to the maintenance of viral genetic diversity in the host communities. However, despite its possible significance, the problem of the simultaneous transmission of plant viruses by vectors has not been investigated in detail. In this review, the current knowledge on multiple viral transmissions by aphids, whiteflies, leafhoppers, planthoppers, nematodes and fungi is outlined.

“…PStV transmission was enhanced to 35% for A craccivora and 45% for M. persicae when the aphid vectors fed on PMV-infected plants before feeding on PStV source plants (Sreenivasulu and Demski, 1988 …”

“…The main vector is Aphis craccivora (Demski et al, 1984a,c;Adalla and Natural, 1988;Sreenivasulu and Demski, 1988;Mangaban et al, 1989a;Natural et al, 1989;Saleh et al, 1989b). Other aphid vectors are: A. gossypii (Adalla and Natural, 1988;Choopanya and Kittipakorn, 1989;Natural et al, 1989), Α. glycines and Hysteroneura setariae (Saleh et al, 1989b), A. citricola, Rophalosiphum maldis and Myzus persicae (Sreenivasulu and Demski, 1988;Warwick and Demski, 1988;Natural et al, 1989;Sreenivasulu et al, 1991).…”

“…(1989a) observed A. craccivora as the most efficient vector among five aphid species assessed. Sreenivasulu and Demski (1988) reported that M. persicae was more efficient than A. craccivora for transmitting PStV and PMV (peanut mottle virus). Transmission rates with M. persicae were 29% for PStV and 9% for PMV, and with A. craccivora were 17% for PStV and 3% for PMV.…”
