Phenotypic and neuropeptidergic control of appetitive behavior in honey bees (Apis mellifera) [PDF]

Communications Biology
Neuropeptide activity in honey bees varies with age, behavioral role, and season. The short neuropeptide F (sNPF) modulates foraging-related behaviors in summer foragers, including food intake, sucrose sensitivity, and sensory processing, but its role in

New Strains of Wolbachia Unveiling the Complexity of This Symbiotic Interaction in Solenopsis (Hymenoptera: Formicidae)

Microbiology Research, 2021
Bacteria of the genus Wolbachia are widely distributed in arthropods, particularly in ants; nevertheless, it is still little explored with the Multilocus Sequence Typing (MLST) methodology, especially in the genus Solenopsis, which includes species ...

Phylogenomic reconstruction reveals new insights into the evolution and biogeography of Atta leaf‐cutting ants (Hymenoptera: Formicidae)

Systematic Entomology, Volume 47, Issue 1, Page 13-35, January 2022., 2022
We employ phylogenomic markers (UCEs) to reconstruct the most extensively sampled phylogeny to date for the ecologically dominant leaf‐cutting ant genus Atta, the major herbivore of the New World tropics. The ancestor of Atta arose 8.5 Ma in the North/Central America + NW South America range, and its descendant species rapidly radiated into Neotropical

Juvenile hormone modulates hydrocarbon expression and reproduction in the german wasp Vespula germanica

Frontiers in Ecology and Evolution, 2022
Juvenile hormone (JH) affects multiple physiological traits in insects. In social insects, besides development, JH has been demonstrated to influence caste determination and the production of chemical compounds.

Is the initial nest depth adapted to favorable conditions for the incipient colony in leaf-cutting ants?

Sociobiology, 2016
The nest dug by the leaf-cutter ant queen of the genus Atta is a vertical tunnel interconnected to a small chamber to hold its offspring and the symbiotic fungus.
