Abstract

  • Non-persistent transmission is the most common mode for aphid-mediated virus transmission.

  • Many non-persistently transmitted viruses indirectly modify aphid behavior in ways that may enhance transmission.

  • Mathematical modeling confirms that enhancing host attractiveness while deterring aphid settling enhances local transmission.

  • Modeling predicts that encouraging settling promotes winged aphid production, which may enhance long distance transmission.

  • Disrupting host-vector interactions may provide a sustainable means to protect crops.
