Fruit flies are used quite a bit for scientific research, from the high school level to the most senior researchers, for several common-sense reasons: ● Small: Fruit flies need little space and are easily handled. ● Basic: They can be anesthetized and manipulated with basic equipment. ● Differences: Males and females are different, and old and young are different, making it easy to tell them apart. ● Short gestation: Fruit fly gestation is only 10-12 days. ● Short life: Fruit flies have a lifespan of 25-30 days. ● Temperature: They do well at room temperature.
