Abstract/Contents:"Using sugar water consumption and mound counts, we evaluated the effectiveness of fipronil and other toxicants against red imported fire ants, Solenopsis invicta Buren (Hymenoptera: Formicidae), around residences and at a golf course fairway at two California country clubs. We counted the number of mounds and measured sugar water consumption at bait stations adjacent to the homes. We compared three formulations of granular fipronil with a bait treatment consisting of pyriproxyfen followed one week later by hydramethylnon. One month after treatment, the bait treatments near the residences showed a significantly greater reduction in ants than the combined fipronil treatments for both number of mounds (reductions of 91% versus 73%) and sugar water consumption (reductions of 91% versus 81%). Fifteen months after treatment, mount reductions for the bait and fipronil treatments were 79% versus 92% (P = 0.06), respectively, and reductions in sugar water consumption were 95% versus 99% (P = 0.03), respectively. Decreases in ant abundance, as measured by sugar water consumption and mound counts, were significantly correlated during the experiment (rs = 0.68). On the golf course fairway, we used sugar water consumption to compare one treatment of pyriproxyfen with one of fipronil. Within one month, the fipronil treatment had reduced sugar water consumption by 68%, whereas the pyriproxyfen reduction was 33%. However, after nine months the respective reductions were similar at 98% and 97%. Overall, on the fairway, the posttreatment results of the fipronil were significantly better than the pyriproxyfen results (P = 0.01)."
