- ... Cell wall material (CWM) derived from hop leaves (Humulus lupulus) was extracted and characterized by fast atom bombardment mass spectrometry (FABMS). The material consists of monosaccharides, fucose, rhamnose, arabinose, galactose, glucose, and xylose, and galacturonic acid oligomers ranging from trimers to octamers, each with a double bond. The unsaturated galacturonic acids showed elicitor acti ...

- ... Behavioral studies using an olfactometer demonstrated that spring migrants of the damson-hop aphid, Phorodon humuli, respond to semiochemicals released by spring migrants feeding on hop leaves. Samples of the total volatiles released on feeding were analyzed by coupled gas chromatography-single cell recording techniques and showed the presence of several active components. Three compounds were ide ...
