Description: Lindane is registered for remedial control of bark beetles; however, forestry uses are controversial and alternative chemicals are needed. Chlorpyrifos (Dursban 4E), carbaryl (Sevimol 4), and fenitrothion (Sumithion 8E) at 1, 2, and 4 pct active ingredient, and lindane at the registered dosage of 0.6 pct were sprayed on lodgepole pine (Pinus contorta Dougl. var. latifolia Engelm.) bolts infested with mountain pine beetles (Dendroctonus ponderosae Hopkins) in Colorado. Mean survival ratios (n=10) of the proportions of beetles emerging from treated bolts to the proportion emerging from control bolts indicated that chlorpyrifos and fenitrothion at 2 and 4 pct were about as effective as lindane in reducing emergence.
