Insect Biochem. 9, pp. 525-533. The last sentence of the Abstract should read as follows: Male S. scolytus beetles from two distinct laboratory cultures were found to produce the (-)-threo and (-)-erythro stereoisomers of 4-methyl-3-heptanol, while females from one of the cultures produced trace quantities of the (-)-erythro stereoisomer only.
