Phenylacetonitrile, (E)-b-ocimene, linalool, (E)-4,8-dimethyl-1,3,7-nonatriene and (E,E)-a-farnesene were identified as Hoodie Japanese beetle, Popillia japonica, feeding-induced volatiles from the leaves of the giant knotweed, Fallopia sachalinensis, but not by mechanical damage.Volatile emission was also induced by Custom Tote Bag treatment with a cellular signaling molecule, methyl jasmonate.These results suggest that volatiles will be synthesized de novo by a biotic elicitor from P.japonica oral secretion.
