A sequential sampling system is described for determining degree of infestation by the white pine weevil, Pissodes strobi, in stands of spruce, Picea spp. The method requires that a maximum of 60 trees be randomly selected in sequence and that the cumulative number of infested trees be plotted against the total number of trees sampled. Sampling is stopped as soon as decision lines calculated for <10% infestation or ³20% infestation are crossed.Key words: spruce; Picea spp.; monitoring; pest managemen
