Abstract：In order to identify the oviposition repellent volatiles from the wilted leaves of Populus yun-nanensis to Phthorimaea operculella (Zeller),the volatiles from wilted leaves of Populus yunnanensis were col-lected by extraction method and identified by gas chromatography -mass spectrometry method in lab.The re-sults showed that 22 kinds of volatiles were isolated from the wilted leaves,and 21 kinds were identified in chemical structure.The content of eugenol was the highest with the relative content as 38.49%.Benzoic acid took the second place with the relative content as 16.37%,and was followed by β-eudesmol,α-eudesmol, benzyl alcohol,phenylethyl alcohol and 2,6 -nonadien -1 -ol with the relative contents as 7.73%,5.22%, 4.32%,4.14% and 4.14% respectively.The other components with lower relative contents were terpenes, acids,alcohols and aldehydes.
