Abstract:

Invasive ant management has evolved from relying solely on broad-spectrum toxic baits to incorporating more targeted, environmentally friendly strategies. This shift toward precision and sustainability inspires future management to focus on integrated, species-specific, and cost-effective approaches. This review highlights innovative approaches, including hydrogel bait formulations, foraging disruption/enhancement via species-specific trail pheromones, insecticide-coated prey baits, and microbial control agents to enhance effectiveness. We also highlighted several advanced techniques involving RNA interference and AI-powered tools that can be integrated into the current invasive ant management framework. Throughout the review, we outline the advantages and limitations of each method under various field scenarios, offering insights into how these innovations can be effectively integrated into invasive ant management. We also emphasize the strategy of utilizing different methods to respond to varying population density levels to maximize control efficacy while minimizing non-target impacts. Tailoring management tactics to population dynamics allows for aggressive suppression during peak infestations and the use of species-specific tools to support ecosystem recovery as populations decline.
