Plant viruses that are transmitted in a non-circulative, semi-persistent (NCSP) manner have determinants on, and/or accessories to, their capsids that facilitate virion binding to specific retention sites in their insect vectors. Bilateral interactions and interactions occurring at the nexus of all three partners (virus, vector and plant) also contribute to transmission by influencing virus acquisition and inoculation. Vector feeding behavior lies at the core of this trio of virus transmission processes (retention-acquisition-inoculation), but transmission may also be mediated by virus infection-triggered and/or vector feeding-triggered plant cues that influence behavioral responses such as vector attraction, deterrence and dispersal. Insights into the multiphasic interactions and coordinated processes will lead to a better understanding of the mechanisms of NCSP transmission.
以非循回、半持久（NCSP）方式传播的植物病毒，其衣壳上具有促进病毒粒子与昆虫介体中特定保留部位结合的决定因素和/或辅助因子。双边相互作用以及三个伙伴（病毒、介体和植物）交界处发生的相互作用也通过影响病毒的获取和接种而有助于传播。载体取食行为是这三重病毒传播过程（保留-获取-接种）的核心，但传播也可能通过病毒感染触发和/或载体取食触发的植物信号来介导，这些信号影响行为反应，如载体吸引力、驱避和扩散。对多相相互作用和协调过程的深入了解将有助于更好地理解 NCSP 传播的机制。
