Understanding the Hygienic Behavioral Dynamics of Ants Using Multi‐State Models
Entomologia Experimentalis et Applicata, Volume 174, Issue 4, Page 361-370, April 2026.Leaf‐cutting ants adjust grooming to pathogen risk and vulnerable nestmates. Multi‐state Markov models reveal shorter, frequent self‐grooming bouts and reduced allogrooming persistence under stress, optimizing social immunity via stigmergic decision‐making.

Potential of alternative control of leaf‐cutting ants using essential oils: A systematic review
Agricultural and Forest Entomology, Volume 27, Issue 4, Page 497-511, November 2025.Abstract Leaf‐cutting ants (LCAs) are abundant and cause considerable damage to agricultural and forest crops in the Neotropical region and are commonly controlled using sulfluramid‐based ant baits. However, this active ingredient is a precursor of perfluorooctane sulfonic acid (PFOS), a persistent, human‐made pollutant that poses serious environmental
