Goss, R.W. (1931) Infection experiments with spindle tuber and unmottled curly dwarf of the potato (Research Bulletin: Bulletin of the Agricultural Experiment Station of Nebraska No. 53)
It is probable that more than one insect species are capable of spreading some of the potato virus diseases. This conclusion was also indicated by repeated observations in the dry-land section of western Nebraska. While aphids are abundant and are probably the chief vectors of potato virus diseases in the more humid sections of the country, they are usually scarce in the western upland plains area and are not present in large enough numbers to account for the rapid spread of spindle tuber and unmottled curly dwarf which sometimes occurs. It was therefore considered advisable to determine the common potato insects in this area and to test them as transmitting agents.
