It is a regeneration pest of for- est and Christmas tree plantation, and nurseries, feeding on stems of seedlings and branch tips of saplings. It breeds in freshly killed stumps and slash. Across the geographic range of pales weevil, different conifer management objectives and constraints result in varying pest impacts and application of different pest management strategies. A questionnaire was sent to 32 states where pales weevil was believed to occur. Responses indicated that pales weevil is an important Christmas tree pest in the north central states, a pest of pine seedlings and Christmas trees in the northeastern states, and principally a pest of pine seedlings in the southern states. Pest management tactics used in the north central states focus on igue 1—The states in which pales weevil is known to occur are stump treatments (removal or application of insecticides). In shaded. the northeastern states, tactics include stump and seedling insecticide treatments and delayed planting of seedlings in seeig sems a oos a saig ac is (igue recently harvested sites. In the South, the most popular tactic 2). is to delay planting of seedlings.
