FIELD EFFICACY of NOVIFLUMURON and SPINOSAD APPLIED to MOUNDS for CONTROL of the RED IMPORTED FIRE ANT, SOLENOPSIS INVICTA BUREN (HYMENOPTERA: FORMICIDAE)

Abstract:
The benzoylphenyl urea insect growth regulator (IGR) noviflumuron and the fast-acting insect neurotoxicant spinosad were field tested separately and in combination to determine efficacy against the Red Imported Fire Ant (RIFA), Solenopsis invicta Buren. Two separate trials were conducted in three separate years (1997, 1998, and 2001) using corncob grit granulated baits. The 1997 trials were conducted in Florida and Georgia while the 1998 and 2001 trials were conducted in Georgia only. The 1997 trials were designed to determine the efficacy of noviflumuron as measured by a dose response. The 1998 trials compared three rates of noviflumuron to commercial standards. Trials conducted in 2001 compared combination treatments of noviflumuron and spinosad to commercial standards.
