Fruit fly life cycle

Development from egg to adult under summer conditions requires about 16 days. The mature larva emerges from the fruit, drops to the ground, and forms a tan to dark brown puparium.

Pupation occurs in the soil. About nine days are required for attainment of sexual maturity after the adult fly emerges.

 The developmental periods may be extended considerably by cool weather. Under optimum conditions, a female can lay more than 3,000 eggs during her lifetime, but under field conditions from 1,200 to 1,500 eggs per female is considered to be the usual production.

Apparently, ripe fruit are preferred for oviposition, but immature ones may be attacked also.
