Abstract

By transmission tests C. obscurella was shown to transmit the wheat striate mosaic virus from wheat to wheat and the oat sterile-dwarf virus from oats to oats. In C. obscurella the incubation times of these viruses seem to be as long as in C. pellucida. In its life cycle and distribution, C. obscurella closely resembles C. pellucida. In Finland the former is earlier but on the whole scarcer than C. pellucida. The ability of C. obscurella to transmit viruses seems to be similar to that of C. pellucida Being scarcer, C. obscurella is obviously of less importance than C. pellucida as a vector of cereal viruses. Locally, it may, perhaps, be of some importance.
