Abstract:

 [Objectives]  The sycamore lace bug, Corythucha ciliata, is a newly found invasive insect in China. We examined the effects of C. ciliata feeding behavior on the volatile organic compounds (VOCs) of London plane tree (Platanus acerifolia) and the behavioral responses of C. ciliata to these VOCs. [Methods]  We measured VOCs in the headspace of the P. acerifolia leaves damaged by C. ciliata using SPME/GC-MS. [Results]  The number and quantity of VOCs generally increased with the duration of feeding by C. ciliata. Four chemicals, including cis-3-hexen-1-ol, 1, 8-cineole, (E)-4,8-dimethyl-1, 3, 7-nonatriene and trans-β-caryophyllene were detected in undamaged leaves. In addition, another five chemicals, including α-thujene, sabinene, myrcene, cis-3-hexenyl acetate and γ-terpinene were induced after feeding by C. ciliata. The behavioral responses of C. ciliata to P. acerifolia leaves and their volatile components were assayed in a Y-tube olfactometer. C. ciliata was significantly attracted by undamaged P. acerifolia leaves compared to a clean air control. Cis-3-hexen-1-ol and 1, 8-cineole significantly attracted C. ciliata, whereas trans-β-caryophyllene repelled this pest. [Conclusion]  A blend of VOCs was detected after P. acerifolia leaves were damaged by C. ciliata and three compounds among these affected the behavior of this pest. These compounds may play an important role in host location by C. ciliata and in the indirect defensive response of P. acerifolia to C. ciliata.
