Platypus pinhole borer affects sprinkler storage of logs in New Zealand.

R. H. Milligan

The pinhole borer, Platypus apicalis White, was found to damage Pinus radiata D. Don logs stored under water sprays at Balmoral State Forest, North Canterbury, although it is not normally endemic in this forest. The initial attack probably originated from infested logs carried down the adjacent Hurunui River during floods and stranded nearby. The Platypus attacks were initiated soon after the stockpile was completed, while logs were still fresh, and also in those which had been stored for up to 3 years. P. apicalis is considered to impose a constraint on sprinkler storage of logs.
