The biology, evidence of infestation and control of the scolytid Dendroctonus ponderosae, a pest of pine trees (Pinus spp.) is described. Natural enemies of D. ponderosae include a dolichopodid fly, 2 coleopterans, one of which is the clerid Enoclerus sphegeus, parasitic hymenopterans, nematodes and woodpeckers. Silvicultural control measures are the most efficient.
