Title: Effect of phloem thickness on heterozygosity in laboratory-reared mountain pine beetles. Forest Service research note

Technical Report ·
OSTI ID:39535

Mountain pine beetles (Dendrocotonus ponderosae Hopkins) were collected from naturally infested trees of lodgepole pine (Pinus contorta Dougl.) in northern Utah. Bettles were reared in logs through six generations in a laboratory, and heterozygosity measured. Heterozygosity levels initially decreased when individual pairs of beetles were reared. However, when beetles were allowed to selected mates at random, heterozygosity rose to levels higher than those in the starting population. Heterozygosity was higher in bettles reared in thin than those in thick phloem.
