Herbivore feeding damage and the plant hormone jasmonic acid induce the emission of volatiles in plants that can influence host finding by herbivores. We investigated the volatile response of ash seedlings to herbivore damage and to exogenous treatment of methyl jasmonate (MeJA), a volatile derivative of jasmonic acid, as well as the behavioral and physiological effects of induced volatiles on the emerald ash borer, Agrilus planipennis. Feeding damage by adults of A. planipennis and MeJA treatment increased volatile emissions from ash compared to unmanipulated controls; although, the blends of the herbivore and MeJA treatments were quantitatively similar, we found qualitative differences between blends. Regardless, females of A. planipennis were attracted to volatiles from plants damaged by conspecifics or treated with MeJA; whereas no effects of volatiles were detected for males. At least five induced compounds from plants, α-farnesene, β-ocimene, linalool, Z-3-hexenyl acetate, and Z-jasmone, elicited an antennal response in A. planipennis. Further tests will examine the behavioral response of A. planipennis to the most prevalent volatiles from induced plants.
