Abstract： The western flower thrip (WFT) Frankliniella occidentalis (Pergande) is a serious pest responsible for causing substantial economic losses in a broad range of crops worldwide.The cuticular hydrocarbons from the cuticle of WFT were analyzed by gas charomatography and mass spectrometry (GC-MS) without solvent.The composition of the cuticular hydrocarbons was then determined by the area normalizing method.Searching the NIST database and comparison with standard mass spectra identified nine constituents in the cuticular hydrocarbons of adults, and eight in those of nymphs.With the exception of 9-methylpentacosane, which was detected only in adults, the same hydrocarbon patterns were found in both adults and nymphs.The principal components of WFT cuticular hydrocarbons were straight and branchedchain-saturated hydrocarbons ranging from C25 to C29.
