Ants exhibit cooperative behaviors and advanced forms of sociality that depend on
pheromone-mediated communication. Odorant receptor neurons (ORNs) express specific …

Life inside ant colonies is orchestrated with diverse pheromones, but it is not clear how ants
perceive these social signals. It has been proposed that pheromone perception in ants …

Background The complex societies of ants and other social insects rely on sophisticated
chemical communication. Two families of small soluble proteins, the odorant binding and …

A major aim of sociogenomic research is to uncover common principles in the molecular
evolution of sociality. This endeavor has been hampered by the small number of specific …

Animals use a variety of sensory modalities—including visual, acoustic, and chemical—to
sense their environment and interact with both conspecifics and other species. Such …

Ants are a highly successful family of insects that thrive in a variety of habitats across the
world. Perhaps their best-known features are complex social organization and strict division …

Eusocial insects use cuticular hydrocarbons as components of pheromones that mediate
social behaviours, such as caste and nestmate recognition, and regulation of reproduction …

The massive expansions of odorant receptor (OR) genes in ant genomes are notable
examples of rapid genome evolution and adaptive gene duplication. However, the …

Studies of the genetic basis and evolution of complex social behavior emphasize either
conserved or novel genes. To begin to reconcile these perspectives, we studied how the …

Expression of colony social organization in fire ants appears to be under the control of a
single Mendelian factor of large effect. Variation in colony queen number in Solenopsis …
