Paper Abstract

The tomography beamline X27A at the National Synchrotron Light Source at Brookhaven National Laboratory was used to study the destructive spruce bark beetle, Dendroctonus rufipennis (Kirby). The x-ray computed microtomography (CMT) instrument is equipped with filtered white x-ray beam with energy of around 18 keV and, alternatively, a monochromatic beam with energy of around 4 to 14 keV and a 1% band pass. The instrument records microtomographic volumes with 108 to 109 voxels and spatial resolution down to about 3- micron voxels. Three-dimensional image reconstruction provides density and spatial information about solid heterogeneous forms. We have demonstrated that CMT images can be used to nondestructively characterize the internal structure of the beetle - symbiont fungal complex as part of an effort to understand the role of these organisms in the devastation of spruce forests throughout south-central Alaska.
