Insecticidal compounds having the formula N-(2-Ra-3-Rb-4-Rh-benzoyl)-N'-(2-Rc-3-Rd-4-Re-5-Rf-benzoyl)-N'-Rg-hydrazine wherein Ra is a halo or lower alkyl; Rb is lower alkoxy, optionally substituted with halo (preferably fluoro); Rc is selected from hydrogen, halo, lower alkyl, lower alkoxy, lower alkoxy lower alkyl, and nitro; Rd, Re and Rf are each independently selected from hydrogen, bromo, chloro, fluoro, lower alkyl, lower alkoxy, and lower alkoxy lower alkyl; Rg is a (C4-C6)alkyl; Rh is hydrogen, lower alkoxy, lower alkyl, or when taken together with Rb is methylenedioxy (-OCH2O-), 1,2-ethylenedioxy (-OCH2CH2O-), 1,2-ethyleneoxy (-CH2CH2O-) or 1,3-propyleneoxy (-CH2CH2CH2O-) wherein an oxo atom is located at the Rb position; and the substituents Rc and Rd, or Rd and Re, or Re and Rf when taken together can be methylenedioxy or 1,2-ethylenedioxy as well as compositions comprising an agronomically acceptable carrier and an insecticidally effective amount of such compounds; and methods of using such compounds and compositions. Also, methods for the production of the compounds and their intermediates, which methods comprise either admixing a 3-amino-2-(substituted)-benzoic acid, sodium nitrite and methanol under acidic conditions or admixing a 3,4-fused heterocyclic benzoic acid and an alkyl lithium reagent followed by subsequent reaction with an electrophilic reagent.
