Protecting larch logs from <i>Tetropium velutinum</i> (LeConte) with lindane emulsion

<i>Tetropium velutinum</i>Abstract
At Trinity Valley, British Columbia, a 1% emulsion of lindane applied on 12 June 1967 protected fresh felled <i>Larix occidentalis</i> Nuttall from attack by <i>Tetropium velutinum</i> LeConte. The same concentration, applied to infested logs on 14 August reduced damage but was too late to satisfactorily prevent larval penetration of the wood.
