Experiments were carried out to determine the periods of acquisition, latent period, inoculation and retention of Potato leaf roll virus when transmitted by the green peach aphid. Trials were set up with the indicators Physalis floridana L. and Datura stramonium L., and the method DAS-ELISA was used to determine the latent carriers of the virus. It was established that after acquisition of PLRV, M. persicae remains viruliferous for its lifetime. The optimal period for acquisition of PLRV by the green peach aphid is determined to be 6 hours, and the minimal is 30 minutes. The latent period of the virus in the vector is 6 hours, whereas the optimal period for inoculation of PLRV by the green peach aphid is 120 minutes and the minimal is 30 minutes. The statistical analysis of the obtained results includes one-way analysis of variance (ANOVA) and Student-Newman-Keuls test for multiple comparisons (SNK).

Key words: PLRV, Myzus persicae, acquisition, latent period, inoculation, retention
