Document Summary

Activities and division of labour of honey bees inside the hive (outline) Division of labour and age polyethism: division of labor refers to the variation in frequency at which individual bees engage in specific activities (variation in degree of specialization for specific tasks). Primary division of labour: between reproductive and worker castes (different behaviors) Secondary division of labor (among worker bees) Age polyethism: series of sequential tasks as bees get older. Primary division of labour: between reproductive (queens and drones) and worker castes (workers) Secondary division of labour: among workers; most of the activities in a honey bee colony are performed by them. Workers perform sequential tasks as they age (age polyethism). Worker bees initially do hive work; they clean cells. Food processing: workers participate in nectar ripening and pollen storing after 12 days. Nectar contains 20-50% solids, the rest is water. Foragers visit 100s of flowers to secure a load.
