Additionally, studies on the possible insect vectors for PMeV transmission have been conducted. It has been shown that PMeV infected papaya plants inoculated with the dsRNA viral genome Figure 5 have a delay in the infection process, suggesting that the plant defense has been elicited that has therefore inhibited viral replication [ 24 ]. The most widely disseminated phytophagous mite species was E. These proteinases are synthesized as inactive precursors that are converted into mature enzymes after tissue wounding and latex exudation [ 37 se.

Revista Brasileira de FruticulturaNaradol, v. However, cross protection depends upon the availability of mild strains that can be used for effective protection against the target virus, and it requires extra agricultural practice and care that limits the benefits of this approach [ 3 ].

These results are interesting because they were obtained under field conditions with a new virus inhibitor formulated against the potyvirus Cultvo in papaya, representing an important step forward in the improvement of the control management of this disease.
