As social insect workers mature, outside-nest tasks associated with foraging and defense are typically performed at higher frequencies. Foraging in ants is often a pheromonally mediated collective action performed by mature workers; age-dependent differences in olfactory response thresholds may therefore proximately regulate task repertoire development.

The endosomal sorting complex required for transport (ESCRT) protein complexes function at the endosome in the formation of intraluminal vesicles (ILVs) containing cargo proteins destined for the vacuolar/lysosomal lumen. The early ESCRTs (ESCRT-0 and -I) are likely involved in cargo sorting, whereas ESCRT-III and Vps4 function to sever the neck of the(More)
