Abstract: Most of plant viruses are transmitted by insect vectors. Hemipteran is the most common vector which spread viruses in nonpersistent, semipersistent and persistent manner. The complex interactions between vector and virus can be classified into two general mechanisms. One is capsid mechanism and other one is helper mechanism. Semipersistent transmitted viruses mainly belong to Closteroviridae, Caulimoviridae, Flexiviridae and Sequiviridae. In recent years, the mechanism of the virus transmission, especially of semipersistent viruses transmission, has attracted an extensive attention. This paper summarizes the research progress of the mechanisms of semipersistent viruses transmission by vectors.

Key words: Semipersistent viruses, Vector transmission, The capsid mechanism, The helper mechanism
