This research evaluated the new red imported fire ant (RIFA) bait Advionâ¢.
Advion⢠contains the active ingredient indoxacarb which, following ingestion, must be
metabolized into an N-decarbomethoxyllated metabolite known as JT333 in order to
become acutely toxic. Laboratory experimentation was conducted to determine the most
effective chemical form and concentration of indoxacarb, as well as the most appropriate
grit size, for use in Advionâ¢. The results indicated that Advion⢠containing indoxacarb
was more effective than Advion⢠containing JT333, that 0.10%, 0.06%, and 0.045%
were the most effective concentrations of indoxacarb, and that standard sized grit (~2
mm) was more effective than small sized grit (<1 mm).
Field experimentation was conducted to determine the most effective concentration
and quantity of Advionâ¢, as well as the most effective placement of the bait, for
obtaining maximum control of RIFA colonies via individual mound treatments. The
results indicated that 10 g (2 Tbsp) of 0.045% Advion⢠placed around the mound in a
circle with a radius of 0.5-3.0 m was the most effective manner in which to treat
individual RIFA mounds. Field experimentation was also conducted to compare the
effectiveness of label-rate broadcast treatment with Advion⢠to the effectiveness of both label-rate broadcast treatment with Amdroî and pre-baiting broadcast treatment with
Advionâ¢. Both pre-baiting broadcast treatment and label-rate broadcast treatment with
Advion⢠ultimately resulted in 98-99% RIFA colony mortality, which was significantly
greater than the 87% colony mortality resulting from broadcast treatment with Amdroî.
The 6.2 d LT90 for label-rate broadcast treatment with Advion⢠was nearly one half that
of the LT90 for pre-baiting broadcast treatment.
Laboratory experimentation was conducted to determine whether RIFA workers were
capable of metabolizing indoxacarb into the toxic metabolite, and the results clearly
indicated that they were. Finally, field experimentation was conducted to evaluate the
effectiveness of label-rate broadcast treatment with Advion⢠at controlling multiple ant
species. The results indicated that label-rate broadcast treatment with Advion⢠resulted
in control of the RIFA and Pogonomyrmex barbatus for at least 7 wk, and Monomorium
pharaonis and Dorymyrmex pyramicus for some period of time between 3 and 7 wk.
