Hello, do you know of portable sensors that can quickly detect insect (aphid) fedding induced volatiles from strawberries? We want to detect hotspots of pests before they spread and become problematic.
Dear A. Nicholas E Birch
Not yet, According to my knowledge
Pls. find the attached files,
Hoping this will be helpful to your project, good luck

Dear Nicolas,
my topic is analysis of aroma-relevant VOCs. For this purpose chromatographic separation by GC is essential.
Nevertheless I know efforts for real-time detection of VOC emissions from plant tissues: doi: 10.1093/aobpla/plt003.
Plant's response to wounding are mostly C6 compounds, so called 'green leave compounds' (GLV from LOX-pathway) and esters like methyl salicylate and jasmonic acid methyl ester (doi: 10.3732/apps.1500044). I have no idea about effective detectors for these compounds.

PTR-MS a non-destructive online mentoring method of VOCs, and I think that it can do it. Still, you need to bring the samples to the lab.

Hi Nicholas, in the event that you are still searching for a way to measure aphid induced plant VOCs, the use of metal oxide sensors may work for your application. These sensors can be set up in a network and monitored remotely. However, it is important to note that these sensors only detect total VOCs (tVOCs), so they will provide a more general understanding of VOC emissions near the sensor. Cheers!
