D. melanogaster, described by Meigen in 1830, appears to have originated in sub-Saharan Africa (Lachaise et al., 1988). The first out-of-Africa habitat expansion of D. melanogaster is thought to have occurred between 10,000 and 15,000 years ago, when it moved to Europe and Asia (David and Capy, 1988).
Where are Drosophila located?
Drosophila melanogaster lives in a wide range of habitats. Native habitats include those in the tropical regions of the Old World, but the common fruit fly has been introduced to almost all temperate regions of the world.

Are fruit flies bad?
Fruit flies are known for their small size, red eyes and brown bodies. These pests are not harmful on their own, but they can be indicative of unsanitary household conditions.
Are fruit flies asexual?
Biologists have long pondered why sex exists, as reproducing asexually seems to make better evolutionary sense. Now, an experiment with fruit flies confirms one advantage of sex: It gives an edge to beneficial mutations. … By crafting synthetic chromosomes, they created flies that reproduce asexually.
How long do Drosophila melanogaster live?
Drosophila melanogaster is a widely used model organism that has distinct advantages in aging research, including short lifespan (mean lifespan, 2–3 months), low maintenance requirements, rich genetic resource and ease to perform genetic manipulation (1).
Who first used Drosophila melanogaster?
How did one species of Drosophila, D. melanogaster, come to be a model system? Harvard entomologist Charles Woodworth was the first to rear D. melanogaster, just after the turn of the 20th century.
How do you tell if a fly is male or female?
Sexing flies
The most simple characteristic to use to differentiate the two is to look at the genitalia of the flies. Males have dark, rounded genitalia at the tip of their abdomen, whereas females have light, pointed genitalia.
Is Drosophila a readily available insect?
Drosophila may be the readily available insect but its main importance is the presence of a number of behavioural genes (mutants described as sluggish, non-climbing, flightless, easily shocked etc.) and marked sexual behaviour. The chromosomes present in it can be easily studied.
Why are Virgin flies used?
Virgin flies are needed to make sure that that the crosses are being appropriately made with the females using the desired sperms to fertilize their eggs. Female Drosophila are considered virgin eight to ten hours after they hatch from their pupa because during that time they are not receptive to male companionship and …
