Product evaluations, field research and new products resulting from applied research

摘要

Three field trials conducted 1999-2000 illustrate test methodology used to evaluate product effectiveness for the control of red imported fire ants (Solenopsis invicta Buren). Even though test designs were different, all were arranged to minimize natural variability to help detect treatment effects. An individual mound treatment test was conducted on the product Exxant to provide efficacy data. Results showed apparent ant colony relocation followed by elimination. A broadcast treatment test was conducted on different application rates and formulations of fipronil. Results showed initial activity similar to a fast-acting broadcast bait product with long duration of control when applied as both broadcast granular and bait formulations. NouGuard, a pepper-based insect repellent was used in an ant foraging suppression study to test its effectiveness in keeping fire ants out of tree canopies. The product showed some short term ant repellence, but failed to completely exclude ants from tree canopies.
