Interactions in Colonies of Primitively Social Bees: II. Some Queen-Worker Relations in Lasioglossum zephyrum

摘要: In Lasioglossum zephyrum, a very primitively social bee, overwintered queens deprived of their workers do not resume cell construction and provisioning, or are long delayed in doing so. Workers, therefore, may play role hibiting from foraging. Workers reared by living with seem to differ those the absence queen. The over wintered queen seemingly plays no inhibiting ovarial development at least some her workers. This paper reports observations on colonies (Dialictus) zephyrum maintained indoor bee rooms nests soil between glass sheets (Michener Brothers, 1971). ob servations were carried concurrently reported Part I this series (Michener, Kamm, 1971), but that an taken field spring near Lawrence, Kansas, was present each colony.
