| differential life history trait associations of aphids with nonpersistent viruses in cucurbits. | the diversity of vectors and fleeting nature of virus acquisition and transmission renders nonpersistent viruses a challenge to manage. we assessed the importance of noncolonizing versus colonizing vectors with a 2-yr survey of aphids and nonpersistent viruses on commercial pumpkin farms. we quantified aphid alightment using pan traps, while testing leaf samples with multiplex rt-pcr targeting cucumber mosaic virus (cmv), zucchini yellow mosaic virus (zymv), watermelon mosaic virus (wmv), and pa ... | 2015 | 26313961 |
| 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 ... | 2013 | 23407835 |
| impact of vat resistance in melon on viral epidemics and genetic structure of virus populations. | cultivar choice is at the heart of cropping systems and resistant cultivars should be at the heart of disease management strategies whenever available. they are the easiest, most efficient and environmentally friendly way of combating viral diseases at the farm level. among the melon genetic resources, vat is a unique gene conferring resistance to both the melon aphid aphis gossypii and the viruses it carries. the 'virus side' of this pleiotropic phenotype is seldom regarded as an asset for viru ... | 2017 | 28587865 |
