Several characteristics make spotted-wing drosophila (Drosophila suzukii) difficult to control. It has a high reproductive rate and strong dispersal abilities, and, unlike most fruit flies, D. suzukii females can pierce the skin of undamaged soft-skinned fruits such as cherries and berries to lay eggs. Also, D. suzukii are highly flexible in their behavior, physiology, and development, and this allows them to quickly adapt to new environments.
