Abstract

Nine synthetic pyrethroids were tested in the laboratory for ovicidal activity to eggs of the fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae). LC@^50 values ranged from 0.320 ppm (Pay-off@?) to 12.230 ppm (Pydrin@?). All pyrethroids were more toxic than diazinon, a standard. The pyrethroids also were effective ovipositional repellents. At their respective ovicidal concentrations cypermethrin (FMC Agricultural Chemical Group) was the least effective. At one-tenth of their respective ovicidal concentrations Ammo@? and cypermethrin (FMC) were the least effective.
