| preference by a virus vector for infected plants is reversed after virus acquisition. | pathogens and their vectors can interact either directly or indirectly via their shared hosts, with implications for the persistence and spread of the pathogen in host populations. for example, some plant viruses induce changes in host plants that cause the aphids that carry these viruses to settle preferentially on infected plants. furthermore, relative preference by the vector for infected plants can change to a preference for noninfected plants after virus acquisition by the vector, as has re ... | 2014 | 24269348 |
| the influence of virus-induced changes in plants on aphid vectors: insights from luteovirus pathosystems. | plant virus infection can alter the suitability of host plants for their aphid vectors. most reports indicate that virus-infected plants are superior hosts for vectors compared to virus-free plants with respect to vector growth rates, fecundity and longevity. some aphid vectors respond preferentially to virus-infected plants compared to virus-free ones, while others avoid infected plants that are inferior hosts. thus, it appears vectors can exploit changes in host plant quality associated with v ... | 2011 | 21549769 |
