Abstract:

Herbivore-induced plant volatiles (HIPVs) from Ulmus pumila were collected by a dynamic headspace sampling method, and analyzed by using GC-MS. Furthermore, electroantennogram (EAG) and behavioral responses of Ambrostoma quadriimpressum (Coleoptera: Chrysomelidae)to the main compounds of HIPVs were investigated. Volatile analyses showed that infestations of A. quadriimpressum markedly increased the emission of 9 compounds, α-farnesene, caryophyllene, cis-3-hexenol, α-pinene, limonene, linalool, methyl salicylate, cis-3-hexenyl acetate and TMTT. The results of behavioral bioassays by using 8 synthetic compounds (except for TMTT) revealed that adult females had a stronger response to linalool, α-farnesene and cis-3-hexen-1-ol than to other compounds tested; and adult males had a stronger response to α-farnesene and caryophyllene. EAG results were basically in accordance with Y-tube olfactometer bioassay. These results may provide practical applications for monitoring and controlling A. quadriimpressum populations in the field.
