Document Summary
Unit 3: honey bee types, nest, and colony cycle. Colony needs and division of labour: sequential pattern of activity is flexible and may change according to colony needs, ex. old bees may perform brood care, or young bees may start foraging earlier. Regulation of behaviour and division of labour: to understand bee behaviour, we need to understand, anthropomorphic comparisons do not allow an objective interpretation of bee behaviour. Internal: pheromone odours, visual cues, changes in temperature in the brood nest, empty cells, etc, external, those associated with food availability in the field, climatic conditions, etc. Look for shelters from weather and predators: honey bee colonies may be housed in human-made hives by beekeepers. Late in winter: queen resumes egg-laying, workers start to rear brood, results in rapid consumption of stored reserves of honey and pollen, need to increase brood temperature to 34-35 c.
