Outline of Final Research Achievements

Honeybee keeps their colony under dramatic change of environment by using social behavior. This study aimed to evaluate honeybee adaptation to environment by measuring energy budget of the hive. The energy budget was estimated from inflow and outflow of carbon from the hive. We found clear daily change of carbon inflow, increasing in evening in summer and increasing noon in autumn. It also decreased from summer to autumn. Total amount of carbon inflow during 3 months was 2.4 kg. Carbon outflow decreased linearly with the decrease of temperature, increasing from summer to autumn. Total amount of the outflow was 0.82 kg.
