- Abstract
A broad range of benzophenone hydrazone derivatives was prepared andtested against selected chewing insect pests, allowing the analysis of structure-activity relationships. Good activity was found only when the aromatic rings were substituted at the 4-positions with an halogen atom and a triflate or perhaloalkoxy group. In contrast, a numberof substituents on the hydrazone part led to active compounds, the best results being achieved with acyl-type substituents. The excellentlaboratory and greenhouse activity of the best representatives was confirmed in semi-field trials against Spodoptera littoralis.
