White grubs and white spruce establishment
On occasion, white grubs cause conspicuous damage in forest nurseries and young plantations (4). Much additional injury to trees in plantations and naturally regenerating old fields apparently goes unrecognized. During studies of constraints on growth of white spruce (Picea glauca [Moench] Voss) in plantations, three kinds of observations were made bearing on such injury and on the overwintering of white grubs (larvae of Phyllophaga Harris sp. and related genera of Coleoptera, Scarabaeidae).
