Diesel Fuel Oil for Increasing Mountain Pine Beetle Mortality in Felled Logs.

摘要

Diesel fuel oil was applied to mountain pine beetle (Dendroctonus ponderosae Hopkins) infested bolts of ponderosa pine (Pinus ponderosa Lawson) in early June. Just prior to the fuel oil applications and 6 weeks later, 0.5 ft(squared) bark samples were removed from each bolt and the numbers of live beetles counted. Beetle survival was 8.3% in bolts arranged in a single layer and 4.8% bolts arranged in 2 layers.
