Abstract:Transmission characteristics of two strains of soybean dwarf virus (SDV-D and SDV-Y) were studied using Japanese and California populations of the aphid vector Aulacorthum (Acyrthosiphon) solani. Latent periods of the virus strains were 12 and 15 hr in aphids from the Japanese colony and 15 and 21 hr in aphids from the California [USA] colony for SDV-D and SDV-Y, respectively. Both strains persisted longer in the Japanese than in the California aphids and SDV-D persisted longer than SDV-Y in both aphid populations. Both strains had minimal acquisition access (AAP) and inoculation access periods (IAP) of 30 min; optimal AAP and IAP were 48 hr. Transmission and acquisition of efficiency of both strains by either vector was greater at 20-22 C than at 29 C, 10-11 C, or 5 C.
