Larvae of the sawfly Neodiprion edulicolus fed on needles of Pinus edulis and were abundant below 1,850 m in elevation at sites near Sunset Crater, Arizona. Coleosporium needle rust, in contrast, infected P. edulis above 1,850 m in elevation and rarely occurred on the same trees as did N. edulicolus. Larval sawfly transferred to P. edulis above 1,850 m fed less frequently on infected twigs and moved off twigs more quickly when transferred to infected trees. Though the negative interactions involved only a small percentage of larval sawfly and rust fungus during this study, the interaction might become more significant in the future if sawflies spread to higher elevations in response to changes in climate or habitat.
