Abstract

In this study the PLRV TRANSMISSION efficiency of five major GENOTYPEs of Scottish M. persicae) were analysed. The GENOTYPEs denoted as types A, B, C, J, and I. In virus TRANSMISSION experiments detached leaves of PLRV-infected Physalis floridana and virus-free seedlings (2-3 leaf) of the same plant were used as virus source and test plant, respectively. Both acquisition and inoculation access periods were 3 days at 18oC with a 16 h photoperiod. One viruliferous aphid per seedling was used for inoculation and 24 seedlings for each GENOTYPE were inoculated. Three weeks after inoculation and based on symptoms or ELISA tests, the numbers of infected plants in each set of inoculated seedlings were determined. The TRANSMISSION experiment was repeated five times. To reveal the factors underlying the differences in PLRV-transmitting abilities of the GENOTYPEs, TRANSMISSION efficiency of PLRV and closely related virus, Beet mild yellowing virus (BMYV), by GENOTYPEs A and J were compared. Significant differences in PLRV TRANSMISSION efficiency of the GENOTYPEs were observed. GENOTYPEs A, B and C transmitted PLRV to more test plants. The comparison of the PLRV and the BMYV TRANSMISSION efficiency showed that GENOTYPEs A and J transmitted BMYV almost with the same efficiency whereas GENOTYPE A transmitted PLRV more efficiently than did GENOTYPE J. These results suggest that such differences are likely to be caused by small variations within the aphid's receptors that recognize PLRV particles and assist their circulation and stability within the aphid's body. It has been shown that the GENOTYPEs A and B also carry all three known insecticide-resistance mechanisms and therefore can potentially increase the spread of PLRV.
