The yeast population in Drosophila cultures where Drosophila are omitted increases exponentially for 5-8 days before reaching a maximum. There is a substantial decrease in the maximum yeast biomass when flies are added to these cultures and the decrease is roughly proportional to the number of files added. Fruit flies undergo complete metamorphosis so there are four distinct stages in their life cycle.

The Drosophila life cycle is short and therefore it is easy to raise a large number of individuals for genetic biochemical and molecular analyses. Eight days in the egg and larval stages and six days in the pupal stage. Leaf through this article to gain more information about this subject.
