My research objectives were as follows: 1) to evaluate efficacy of two insecticides for excluding subcortical beetles from pine trees ({Pinus} spp.), and of two trap heights (1.5 and 4 m) and designs (single- or double-pane window traps) in maximizing trap catches; and 2) to assess the effects of prescribed burning on subcortical beetles and mortality of pines. Carbaryl and bifenthrin were equally effective in excluding beetles. Bark beetles caught at two heights reflect known vertical partitioning on trees. Catches of single- and double-pane window traps were similar. Effects of fire on tree mortality with beetle exclusion could not be determined. Trees subjected to fires in 2009-2010 and girdled in 2011 indicated that beetle catches were lower and species composition different for trees burned in 2011. Stands burned in 2010 and 2011, respectively, had higher volume of logs and basal area of snags; trends did not correlate with beetle attributes.
