Beet leafhoppers carrying beet curly top virus acquired from feeding on infected plants or on extracts from infected plants were readily identified by enzyme-linked immunosorbent assay. Results correlated very well with a bioassay consisting of caging leafhoppers individually on sugar beet seedlings and determining percentage of infection. This method was used to compare virus levels in field populations of beet leafhoppers.
