Other claims from this paper (6)
- Association Attacks by Scolytus ventralis on white fir were correlated with periods of low precipitation.
- Association Attacks by Scolytus ventralis on white fir were correlated with medium to heavy infestations of true mistletoe.
- Association Trees were seldom attacked when the running mean precipitation was above 54 in.
- Association Attacks by Scolytus ventralis were significantly more frequent on trees with substantial amounts of mistletoe.
- Association Attacks by Scolytus ventralis were often a year or more earlier on trees with substantial amounts of mistletoe.
- Mechanism Heavy mistletoe infestation is suggested to make white fir trees more susceptible to beetle infestation, possibly through moisture stress.
