Abstract: The quantitative relationship between the structure of oxime-ether compounds containing sulfur(oxygen) and their insecticidal activity against leafhopper was studied by comparative molecular field analysis(CoMFA). The results showed that the contributions of steric and electrostatic fields to the activity were 47.5% and 52.5%, respectively. The coefficient q2 of cross validation and the relation coefficient r2 of non-cross validation for the model established by the study were 0.628 and 0.971, respectively, its F value was 133.840 and the standard deviation was 0.109. These values indicated that the model might have a good predictability. The contour maps of the model will give the basis on the structure modification.
