Abstract In this experiment，38 cucumber（Cucumis sativus L.） samples of different ecological
types were tested．The chlorpyrifos pesticide was sprayed on cucumber samples during the full fruit
period．Then we tested the samples with gas chromatography，in order to evaluate the chlorpyrifos
residue in the main cucumber germplasm resources．The results showed that there were great
differences between different samples fruits in the level of chlorpyrifos residue. The chlorpyrifos residue
is 0.795 mg·kg-1 on average，the change is between 0.072-1.835 mg·kg-1，and the CV is 0.549．
Furthermore，different chlorpyrifos residue levels exists in cucumbers fruits of different ecological types
and cucumbers from different producing areas. Only one sample，with chlorpyrifos residue lower than
the national standard 0.1 mg·kg -1（GB2763—2005），was selected.
