N2 - Sixteen Asian pear cultivars grown at Virginia Gold Orchard near Natural Bridge, VA were evaluated for shoot damage from the seventeen-year cicada (Magicicada septemdecim L.), followed by fire blight infection by the bacterium Erwinia amylovora [(Burr.)Winsl. et al.]. The Japanese pear cultivars, 'Yoi nashi' and 'Ichiban nashi,' proved to be the most susceptible; whereas two Korean types, 'Ar-rirang 1' and 'Korean Giant,' were most resistant. Two Japanese cultivars, 'Shinko' and 'Singo,' proved to have intermediate resistance. All cultivars exhibited some degree of cicada damage and 68% showed a strong correlation between cicada injury and fire blight severity. Those with the softest woody branches were attacked and injured most severely.
