Colony and population genetic structure of the newly invasive white-footed ant (Technomyrmex difficilis) in the United States.

ABSTRACT: The invasive white-footed ant Technomyrmex difficilis has emerged as a rising pest in several regions, yet its invasion dynamics remain underexplored. This species outcompetes native ants and causes agricultural losses by tending pest insects, including aphids and mealybugs. This study provides the first integrated analysis of the species' behavioral, chemical, and genetic variation across Texas and Florida populations. Observations suggest that the recently discovered Texas population of white-footed ants originated from Florida. Microsatellite and mitochondrial DNA analyses revealed low genetic diversity in both populations, with a shared haplotype consistent with the Texas population originating from Florida. STRUCTURE analysis further supported genetic clustering between the two region
