A botanical insecticide based on extracts of seeds from the neem tree, Azadirachta indica A. Juss, was applied systemically to Sitka spruce and white-Engelmann spruce hybrids and sprayed directly onto the leaders of white-Engelmann spruce to test its efficacy in controlling the white pine weevil, Pissodes strobi Peck. Neither treatment had any effect on weevils or damage in the white-Enge1mann spruce, and control was not economical.Key words: neem; weevil; azadirachti
