Azteca ant

Systematic position. The Azteca genus belongs to the order Hymenoptera and the family Formicidae. These ants are well-known arboreal dwellers distributed primarily across the Neotropics, where they interact closely with the native flora and fauna.

Host plants and damage. They frequently colonize economic crops such as cacao, coffee, and citrus trees. While the ants themselves do not consume plant tissues, their presence is linked to the proliferation of serious secondary pests, making them a significant agricultural concern.

Biology and life cycle. Azteca ants are highly social insects that form complex colonies. They often nest inside plant stems or construct carton-like nests on branches. The life cycle involves a complete metamorphosis through egg, larval, and pupal stages before reaching the adult worker, queen, or drone phase.

Nature of damage. These ants engage in a mutualistic relationship with sap-sucking insects like mealybugs and aphids. By protecting these pests from natural predators and moving them between plants, the ants foster massive infestations that cause direct harm to the host plant through sap depletion and sooty mold growth.

Control measures. Management strategies include:

• Applying sticky bands on tree trunks to block ant access.
• Using targeted insecticide baits to eliminate queen colonies.
• Controlling sap-sucking insects to deprive ants of their food source.
• Sanitary pruning of infested branches to reduce nest density.
