Feeding is fundamental to any heterotroph organism; in its role to quell hunger it overrides most other motivational states. But feeding also literally opens the door to harmful risks, especially for a saprophagous animal like Drosophila; ingestion of poisonous substrate can lead to irreversible damage. Thus feeding incorporates a series of steps with several checkpoints to guarantee that the ingestion remains beneficial and provides a balanced diet, or the feeding process is interrupted.

Subsequently, we will summarize and describe the feeding process in Drosophila in a comprehensive manner. We propose eleven distinct steps for feeding, grouped into four categories, to address our current knowledge of prandial regulatory mechanisms in Drosophila.

喂养对于任何异养生物都是至关重要的。它在消除饥饿方面的作用超越了大多数其他动机状态。但是从字面上讲，喂养也为有害风险打开了大门，尤其对于像果蝇这样的腐食性动物而言；摄入有毒的底物会导致不可逆转的伤害。因此，饲喂包括一系列带有几个检查点的步骤，以确保摄取保持有益并提供均衡饮食，否则饲喂过程会中断。

随后，我们将对果蝇的喂养过程进行总结和描述。我们提出了11个不同的喂养步骤，分为四个类别，以解决我们目前在果蝇中膳食调控机制的知识。
