Transmission of peach mosaic ?closterovirus by Eriophyes insidiosus
Peach mosaic ?closterovirus (EPPO A1 quarantine pest) affects several Prunus species in USA and Mexico and is spread by the peach bud mite, Eriophyes insidiosus. Experiments were made on the transmission process of peach mosaic closterovirus by E. insidiosus. Results have shown that: 1) the transmission efficiency of a single mite was as high as 17%; 2) the minimum inoculation access period was between 3 to 6 h; 3) the minimum acquisition access period was of 3 days. The authors felt that unlike most other mite vectors which transmit diseases in a persistent mode, E. insidiosus appeared to transmit peach mosaic ?closterovirus in a semi-persistent mode.
