Individual ponderosa pines, Pinus ponderosa Lawson, can be protected from Dendroctonus ponderosae Hopkins attacks by spraying the boles with 2% carbaryl-water suspension. Although lindane emulsion at 2% gives equal protection, numerous pitch tubes leave trees cosmetically inferior. Other dose rates and materials are considered inferior. Insecticides tested kill a broad spectrum of insects, including predators of the mountain pine beetle. Predators may have been attracted to certain insecticide formulations.
