This report covers the first full year of operation of our gammaray
spectrometry facility. A part of the contract period was devoted
to calibration of the instrument, and therefore, a brief report on this
procedure is included.
Factors considered were phloem moisture, sour-phloem (which
may be furthered by the presence of ample phloem moisture), oleoresin of the host, and the presence of unmated female beetles in
suitable host material.
Levels of phloem moisture present in variously prepared logs
in the field ranged from about 100 to upwards...
