The present work reports the differences between the ovarian grow in queen and worker larvae of A. mellifera, from the start of differential feeding. The observations made of the growth rates in larvae of both castes showed that the queen and worker larvae have the same rates of cephalic capsule growth from one instar to another but the weight gain is greater in queens. In the same way, the draw areas of ovaries of queens increase more and continuously, while from the 5th instar on the ovaries of workers decrease in size. The decrease is due to a loss of ovariole numbers that starts early in the worker larvae and increases in the 4th-5th instar. The ovarian shape in queens and workers became different in the last larval instars.
本研究报告了从差异饲喂开始，意大利蜜蜂蜂王和工蜂幼虫卵巢生长的差异。对两种蜂型幼虫生长速率的观察表明，蜂王和工蜂幼虫从一个龄期到下一个龄期的头壳生长速率相同，但蜂王的体重增加更多。同样，蜂王卵巢的发育面积增加得更多且持续增加，而从第5龄期开始，工蜂的卵巢大小减小。这种减小是由于工蜂幼虫早期卵巢管数量减少，并在第4 - 5龄期增加。蜂王和工蜂的卵巢形状在最后一个幼虫龄期变得不同。
