Most species of Drosophila are nuisance pests attracted to overripe fruits on which females lay their eggs. First instar one day in length Day 3. Adults are small 15-30mm with red eyes and with unbroken black striped on the.

DROSOPHILA LIFE CYCLE EXPERIMENT Drosophila melanogaster is a small common fly found near unripe and rotted fruit. Life cycle and its culture. Drosophila suzukii is unique in that they are attracted to ripening or ripe fruit and the female is able to penetrate the skin of ripe fruit with her serrated ovipositor to lay eggs inside the fruit.

Consists of a number of stages. The oocyte is derived from a germ cell that divides four times to give a family of 16 cells that remain in communication with one another via cytoplasmic bridges gray. The rate of development is dependent on temperature being more rapid at higher temperatures.
