Abstract:The effectiveness of several formulations of Sevin (carbaryl) for remedial control of the spruce beetle, Dendroctonus rufipennis (Kirby), was investigated in Lutz spruce, Picea x lutzii Little, in south-central Alaska. Treatments of infested 0.5-m long bolts consisted of Sevin 4 oil in water, Sevin SL in water, Sevin 80S in water, Sevin 80S in diesel, and diesel alone. Sevin SL was more effective in providing remedial control of emerged Ist-yr and parent adults compared with nonemerged adults; Sevin 80S in diesel and Sevin SL provided adequate remedial control of 2nd-yr emerged adults. Sevin 80S in diesel provided the best remedial control of larvae but all other chemicals tested were ineffective for control of pupae. From the infornlation reported here, remedial treatment of individual spruce trees infested with spruce beetles can probably significantly reduce the number of beetles that would normally emerge and attack adjacent standing green trees.
