“…For example, Hooks et al (2009) also found a higher transmission efficiency of Banana bunchy top virus by aphids based on laboratory experiments compared to commercial agricultural conditions. Another study that included transmission of Cucumber mosaic virus and Zucchini yellow mosaic virus by multiple aphid species found that the relative transmission rates between field and laboratory conditions depended both on aphid and virus species (Castle et al 1992). We propose that this question should be addressed in more detail in future studies due to its epidemiological relevance.…”

TitleAbstract Grapevine leafroll-associated virus 3 (GLRaV-3) is associated with the economically damaging grapevine leafroll disease, and is transmitted in a semi-persistent manner by several mealybug species. We performed the first controlled field study of vectormediated inoculations with GLRaV-3 in a commercial vineyard with previously asymptomatic vines, and monitored the vines during four growing seasons. We then compared the outcome of vector-mediated inoculations in the field study to an analogous laboratory study. In the vineyard, about half of all inoculated plants became infected with GLRaV-3, fewer than in the controlled laboratory inoculations. Mealybugs had lower settling and feeding success in the field than in the laboratory inoculations. Our study suggests that laboratory studies may overestimate transmission efficiency. All successfully inoculated vineyard plants first became symptomatic one growing season after inoculations, and berry quality declined within one year after inoculations. Vineyard plants were effective virus sources one year after inoculations. Our findings generally indicate that newly symptomatic vines in commercial vineyards probably became infected during the previous growing season, and a decline in berry quality can be expected during the same year in which symptoms appear.

“…WMV and ZYMV have overlapping host ranges ( primarily comprising cucurbits [21,22]), cause similar symptoms [22] and are transmitted (non-persistently) by the same aphid species, although with differing efficiency [23]. Like other potyviruses, WMV and ZYMV have unipartite single-stranded positive sense RNA genomes (similar in size and organization [20,24]) encoding a polyprotein, and both use a helper-component protein for attachment to the aphid stylet [25].…”

Outcomes of co-infection by two potyviruses: implications for the evolution of manipulative strategies

Recent studies have documented effects of plant viruses on host plants that appear to enhance transmission by insect vectors. But, almost no empirical work has explored the implications of such apparent manipulation for interactions among co-infecting pathogens. We examined single and mixed infections of two potyviruses, watermelon mosaic virus (WMV) and zucchini yellow mosaic virus (ZYMV), that frequently co-occur in cucurbitaceae populations and share the same aphid vectors. We found that ZYMV isolates replicated at similar rates in single and mixed infections, whereas WMV strains accumulated to significantly lower levels in the presence of ZYMV. Furthermore, ZYMV induced changes in leaf colour and volatile emissions that enhanced aphid (Aphis gossypii) recruitment to infected plants. By contrast, WMV did not elicit strong effects on plant-aphid interactions. Nevertheless, WMV was still readily transmitted from mixed infections, despite fairing poorly in in-plant competition. These findings suggest that pathogen effects on host-vector interactions may well influence competition among co-infecting pathogens. For example, if non-manipulative pathogens benefit from the increased vector traffic elicited by manipulative competitors, their costs of competition may be mitigated to some extent. Conversely, the benefits of manipulation may be limited by free-rider effects in systems where there is strong competition among pathogens for host resources and/or access to vectors.
