Comparing the Histological Structure of the Fat Body and Malpighian Tubules in Different Phases of Honeybees, Apis mellifera jemenatica (Hymenoptera: Apidae)

Background and Objective: The honey bee has high economic importance as a successful pollinator in several agricultural crops worldwide and as a source of valued products.The objective of the current study was to and determine the effect of the difference in nutrition in the embryonic stages on the fat body and malpighian tubules of Apis mellifera jemenatica range in different ages.Materials and Methods: In the larval stage of which two ages, the third and fifth have been studied in both the queen and the worker; as queen larvae were fed an intensive diet of royal jelly throughout the larval stage evolution, while the worker larvae were fed royal gel in the first three days only, but in fifth age, it was fed a mixture of honey and bee bread.Results: Several differences were found from one developmental stage to another.Fatty bodies spread throughout the body and fill the internal spaces between the organs.Where fatty bodies increase the size of trophocyte cells with the accumulation of fatty substances and waste inside them with gaps.Either in the malpighian tubules in worker were characterized by the presence of cubic cells with clear nuclei and the composition of these cells based on the basement membrane with the presence of gaps within the cells and the inner cavity is narrow, but in the queen is characterized by the size of more than the worker.Conclusion: It seem very useful to link the study of histological structure recorded at the cellular or tissue levels with the development of age and with changes at the community levels.
