The evolution of eusociality in Hymenoptera—encompassing bees, ants, and wasps—is
characterized by multiple gains and losses of social living, making this group a prime model …

Highlights•Bumble bees face increasing physiological challenges in light of global
change.•Most progress in ecophysiological research is related to thermal biology and …

Queens and workers of eusocial Hymenoptera are considered homologous to the
reproductive and brood care phases of an ancestral subsocial life cycle. However, the …

Division of labor (DOL) is a characteristic trait of insect societies, where tasks are generally
performed by specialized individuals. Inside workers focus on brood or nest care, while …

Accumulating evidence suggests that neonicotinoids may have long-term adverse effects on
bee health, yet our understanding of how this could occur is incomplete. Pesticides can act …

Evidence accumulates that the functional plasticity of insulin and insulin-like growth factor
signaling in insects could spring, among others, from the multiplicity of insulin receptors …

Behavioral plasticity is key to animal survival. Harpegnathos saltator ants can switch
between worker and queen-like status (gamergate) depending on the outcome of social …

Adipokinetic hormones (AKHs) are well known to mobilize lipids and carbohydrates for
energy-consuming activities in insects. These neuropeptides exert their functions by …
