title: Social facilitation and development in Ephestia kühniella Z.
abstract: Total time required for larval and pupal development in Ephestia kühniella Z. was significantly modified when habitable space of the food mass was increased by dilution with a nontoxic sawdust. Doubling the living space resulted in an increased developmental rate, presumably due to a reduction in the number of larval interactions. Tripling the living space, however, produced a somewhat unexpected delay in development, accompanied by a marked increase in variance about the means for both males and females.
