Abstract

When a few large trees are to be sampled, emergence traps provide more reliable counts of mites that are phoretic on southern pine beetles than either removal of bolts or removal of 100 cm2 bark discs. When a large sample from smaller trees is required, removal of bolts is preferable to removal of disc samples. Emergence traps or bolt samples are preferable to disc samples because: (1) fewer mites are lost during transportation and rearing; (2) mites are not left on the xylem; (3) fewer die from desiccation during rearing; and (4) fewer non-phoretic stages accumulate in the collecting medium.
