Scientists at the University of Hawaiʻi at Mānoa’s College of Tropical Agriculture and Human Resilience (CTAHR) have uncovered a surprising dietary preference in the invasive little fire ant (Wasmannia auropunctata): cooked beef and sunflower seeds are far more attractive than traditional tuna baits. The findings, published in the Journal of Applied Entomology, stem from controlled laboratory food-choice tests that challenged long-held assumptions about ant foraging behavior.
Researchers discovered that these stinging pests consistently selected protein-rich cooked beef and high-fat sunflower seeds over water-packed tuna—commonly used in pest control traps. This shift in bait strategy could significantly improve detection and eradication efforts across Hawaii and other vulnerable Pacific regions.
