SURVIVAL OF WOOD BORERS (COLEOPTERA: CERAMBYCIDAE, BUPRESTIDAE) IN WATER-STORED LOGS

In logs that have been stored for at least a month in water, 3 to 6 per cent of borer larvae may survive, depending on the size of logs and whether the larvae are under the bark or in the wood. In sawlogs, larval survival is three times as great in the portion of the log above the water as in the submerged portion. These survival figures may be acceptable for control purposes but should be considered in certification of logs for export.
