Remarks from the Conference Chairperson Hey folks, I would just like to thank everyone who attended the IFA and Invasive Ant Conference in Charleston and contributed to the success of the meeting. This truly is a meeting that is for the people who attend. It is successful only because everyone participates. For my part, most of you saw it was a family affair. My wife did the registration and made my life very easy on that score. I can't thank her enough for coming to my rescue. I'd also like to thank the county agents that moderated, and worked the A/V. It was very nice to delegate this and not worry about it again. Again, thanks for your participation. It has truly been a privilege to organize this meeting and I look forward to attending next year's meeting in Oklahoma.

Bifenthrin: A Review of Product Performance Field Tests Against Red Imported Fire Ants Charles L. Barr, Ph.D., Barr Research and Consulting Introduction Since beginning work with red imported fire ants (Solenopsis invicta Buren) in 1989, I have used the pyrethroid bifenthrin in more field trials than any other contact insecticide. These trials have included individual mound treatments (IMTs) and broadcast applications with more than half a dozen granular carriers and several liquid formulations. Many of the trials tested the effectiveness of these various carriers and formulations, while others used commercially available bifenthrin products as standards. In 2006, I was hired by a client to review this body of work as support for their potential development of a broadcast bifenthrin fire ant control product. In reviewing these files, I discovered that I had personally applied bifenthrin as a broadcast in 10 tests since 1989. Review of the data showed certain trends in product performance, though I did not “crunch the numbers” to do any kind of formal comparison. Since that report, I have conducted one very large bifenthrin broadcast test involving three different carriers with 10 total treatments and another test where bifenthrin was included as a standard. I also conducted four IMT trials that involved treating over 700 mounds. This level of industry interest caused me to wonder about the appeal of bifinthrin and, more importantly, to go through the data in detail to help support the trends I had noticed in the report. It is important to note that this article concentrates on broadcast applications only. When properly applied, bifenthrin and most other contact insecticides result in near 100% control of individually treated mounds regardless of mound size, weather, season and many other factors. This observation is quite important in an overall fire ant control strategy and will be discussed later, but it does not leave much room for investigating interesting effectiveness trends. Materials and Methods The trials included in this analysis were conducted at various sites in east-central Texas from 1989 through the summer of 2007. Plots in all but one test were 0.25 acres in size with smaller evaluation areas included within the plots. The remaining test involved 0.125-acre plots evaluated to the edge. All treatments and controls were replicated four times. The application rate of the bifenthrin active ingredient was 0.2 lbs/acre in all trials. Some trials included other rates, but these data were not analyzed here. A trial was included in the analysis if it had at least one treatment using a broadcast bifenthrin product applied at 0.2 lbs a.i. per acre, regardless of carrier type. Effectiveness in all trials was based on the number of active mounds. Because of extreme variation in natural fire ant mound numbers due to weather and season, it was necessary to calculate the percent control of each treatment in each test compared to the untreated mound numbers in that test and on that evaluation date. Therefore, the data presented is the mean percent control from appropriate tests at appropriate intervals post- treatment. Bifenthrin was also compared to other popular fire ant control products for which I had sufficient data for a meaningful analysis and included: 0.73% hydramethylnon bait (usually Amdro® or AmdroPro®), 0.045% indoxacarb (Advion®) and 0.0143% granular fipronil (TopChoice®). Data from these treatments were analyzed in a similar manner if any or all of them were included in a trial that also included broadcast bifenthrin. Results and Discussion Trials were first divided into spring/summer (April - early July) and fall (September- November) treatments since performance differences had been observed between many of these trials.
