Abstract: Most plant viruses are transmitted by vectors,among which insect is the most important category. The tripartite interaction of plant-virus-vector is complex and specific. So far,virus has become a powerful booster for co-evolution of plant-virus-vector due to its rapid reproduction and fast variation,which then is conducive for its effective transmission. The effects of virus on vector insects can be direct and indirect. The indirect effect refers to such process,i.e.,virus infection to host plants results in the changes on the photosynthesis,secondary metabolism,nutrition components,and signal pathways of plants,which thus affects insects’ biological properties,such as their behavior of host selection,growth and development,fertility and so on,and finally influences virus’ transmission efficiency. The biological impacts of virus-infected host plants on piercing-sucking insects are reviewed here,aiming at providing evidences for the prevention and control of plant virus diseases.

Key words: plant virus, host plant, piercing-sucking insects, biological characteristic
