USGA Summary Points:Field-collected adult southern mole crickets from Riviera CC, Miami FL (Spring 2022) and tawny mole cricket nymphs from Mobile AL (Fall 2022) received topical applications of technical grade fipronil in acetone in the laboratory. Despite insecticide applications, staff at both locations reported outbreaks of mole crickets. All southern mole crickets from Florida were killed by the 1000 ppm rate within 72 hours of treatments and about half of the test insects were killed by the 10 ppm rate at 96 hours. Similarly, 1000 ppm was enough to kill 100% of tawny mole crickets from a single population in Alabama in 48 hours. After 96 hours, 100% of tawny mole crickets from that population treated topically with 5 ppm were dead. It is challenging to relate field application rates to ppm of fipronil in solution applied directly to the insect. There is little evidence to support a concern for resistance to fipronil at either site we sampled. If fipronil is applied at label rate, there would be 260 micrograms of fipronil per sqft. That is 26x the highest contact dosage that provided 100% mortality in the lab experiment. The breakthroughs in treatments at both sites may be due to treatment timing, application rates, or re-infestation after application. Lighted driving ranges and golf courses are attractive to mole crickets in flight. At best, fipronil provides 4 to 6 months of residual control when applied at peak egg hatch.
