چکیده انگلیسی
The mushroom bodies are structures present in the insect brain described as centers for the neural basis of learning, memory, and other higher functions. Honeybees (Apis mellifera) are insects with a sophisticated system of spatial orientation and possess well-developed learning and memory capabilities, which are associated with neural and brain structures. Thus, the present study aimed to compare the mushroom bodies during post-embryonic development and in newly emerged males, workers, and queens using light and transmission electron microscopy to examine how differential morphological characteristics are established during development. Measurements of structures were also taken in several post-embryonic developmental phases in order to evaluate size differences during the process and in the adult organs. The results show that workers, queens, and males exhibit temporal and size differences during the post-embryonic development of mushroom bodies, probably as adaptations to differences in behavior complexity. The mushroom bodies of workers are precociously formed and are larger than those of queens and drones. Thus, workers have the largest mushroom bodies resulting from differential development during metamorphosis.
