Many aphids are parthenogenetic during part of the life cycle, such that females can produce unfertilized eggs, which are clones of their mother.
All such young are females (thelytoky), so 100% of the population at these times can produce more offspring.
Many species of aphid are also viviparous: the young are born live rather than laid as eggs.
These adaptations enable aphids to reproduce extremely rapidly when conditions are suitable.
