Formicidal Potential of Thymol Derivatives: Adverse Effects on the Survival and Behavior of Acromyrmex balzani

Agriculture, 2023
Leaf-cutting ants are important pests of agricultural and forest crops. Currently, few insecticides are registered for the control of these insects. Natural bioactive molecules can serve as models for the synthesis of new insecticidal compounds. Such ant

Sanitizing the fortress: protection of ant brood and nest material by worker antibiotics [PDF]

, 2013
Social groups are at particular risk for parasite infection, which is heightened in eusocial insects by the low genetic diversity of individuals within a colony. To combat this, adult ants have evolved a suite of defenses to protect each other, including

Reciprocal genomic evolution in the ant–fungus agricultural symbiosis

Nature Communications, 2016
Attine ants, including the leaf-cutting ants, cultivate fungi as their sole source of food. Here, Nygaard et al. use whole genome and transcriptome sequences from seven ant species and their fungal cultivars to reconstruct the reciprocal genetic changes ...
