The infection of leafhoppers by Western X-disease .virus II. Fluctuation of virus concentration in the hemolymph after injection.
Transmission curves obtained from Colladonus montanus adults, subinoculated as nymphs with hemolymph from vectors previously injected with Western X-disease virus (WXV), were used to construct a curve showing relative virus concentration in the hemolymph after injection. An increase in WXV titer of approximately 3 log units was demonstrated between the 3rd and 21st days after injection. This was followed by a 1.5 log unit decline by the 37th day after injection. Transmission by the initially injected insects followed a similar course.
