Stepwise multiple regression techniques were used to statistically
analyze the relationships between damage caused by the pine needle
sheath miner Zell-aria haimbachi (Busck); a needle miner, Oenerostoma
etrobivorum (Zeller); sugar pine tortrix, Choriatoneura Zambertiana
(Busck); and ambient and foliar concentrations of fluoride in lodgepole
pine (Pinue contorta v. Zatifolia Engelm.) near the Anaconda
Aluminum Company at Columbia Falls, Montana. Foliar fluoride concentration
was significantly related (0.01 level) to needle miner
damage and to damage caused by the pine needle sheath miner. The
data strongly indicate that fluoride is a contributing factor in predisposing
pines to damage by these insects. |
