Collecting PSHB volatiles using different approaches in search of possible pheromones
The frequency that compounds were detected in collections (% of samples that were positive) are shown. Media are listed as either SPME fibers exposed to still air head space of the odor source, volatile collection of head space air flowing through a trap that was subsequently eluted into a solvent, or a direct solvent rinse or extract of the odor source. Odors were contained in and collected from various receptacles, consisting of either the rearing tube or a jar, a Pasteur pipette, within the beetle gallery in the colonized diet, or by touching the SPME fiber to the odor source.
List of volatile collections conducted in search of possible pheromones
In exploratory volatile collections, for each sample the contents of the sample, approach used, and GCMS peak areas for the three compounds of interest are listed.
