描述了从一般不飞行的蜂群到觅食蜂的个体发生转变的生理相关因素。在6个蜂群中，工蜂的觅食活动高峰发生在15至32日龄之间，具体取决于季节。整个湿体质量下降了大约。40%与向觅食行为的转变有关。体重的全部损失发生在腹部，总减少量的85%发生在消化道，不包括蜂蜜作物。觅食蜂的最大胸腔特定耗氧量（.ovrhdot. vo2）比8-12日龄的蜂群高10%。胸廓特异性最大值升高。VO2与身体质量的降低相结合，产生了50%的质量比最大值。与蜂群相比，觅食者的VO2。觅食者胸腔的糖原储存量增加了一倍。丙酮酸激酶活性在4日龄时增加了5倍，此后保持不变。柠檬酸合酶活性在4日龄时增加了10倍，然后在老年蜜蜂中下降。这些发现表明，工蜂对觅食期的生理专门化可能是蜜蜂时间聚醚化时间表的一个重要好处。
Physiological correlates of the ontogenetic transition from generally nonflying hive bees to foragers were described. Peak foraging activity of workers occurred between 15 and 32 days of age in six honeybee colonies, depending on season. Whole wet body mass decreased .apprx. 40% in correlation with the transition to foraging behavior. The entire loss of mass occurred in the abdomens, with 85% of the total decrease occurring in the digestive tract exclusive of the honey crop. Maximal thorax-specific rates of oxygen consumption (.ovrhdot.VO2) were 10% higher in foragers than in 8-12-day-old hive bees. The increase in thorax-specific maximal .ovrhdot.VO2 combined with the decrease in body mass yielded a 50% increase in mass-specific maximal .ovrhdot.VO2 in foragers compared to hive bees. Glycogen stores of the thorax doubled in foragers. Pyruvate kinase activities increased fivefold up to 4 days of age and thereafter remained constant. Citrate synthase activities increased tenfold up to 4 days of age and then declined in older bees. These findings suggest that physiological specializations of workers to the foraging period may be an important benefit of the temporal polyethism schedule in honeybees.
