Characteristics of Douglas-Fir Logs in Relation to Ambrosia Beetle Attack
Attacks of an ambrosia beetle Trypodendron lineatum (Olivier) were examined in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) logs cut at various times. Brood production was higher in autumn- and winter-felled logs and in logs from faster growing trees. Outer sapwood moisture was similar in all trees at felling. It changed little during the study and was unrelated to attack. At the time of heavy attack, sapwood of the preferred autumn- and winter-felled trees had little or no starch and gave weak or negative reactions to tetrazolium red. The unattractive spring-felled logs contained appreciable starch and gave marked tetrazolium reactions.
