Drosophila refers to insects in the order Diptera, family Drosophidae, and has been described as having over species4000Species, including a series of model species such as Drosophila melanogaster and Drosophila melanogaster. Widely used as indoor and outdoor research materials for genetics and evolution, especially for Drosophila melanogaster. It is easy to cultivate, has a short life history, and can be cultivated in less than two weeks at room temperature. As a common model organism, Drosophila melanogaster has been extensively used in genetic and developmental biology research.
