Parasitoids' lifestyle requires an intensive specialization process at different steps of the life cycle. As a consequence, parasitic wasps are usually specialized on very few hosts. This peculiarity makes them one of the most used biological control agents against insect pest. However, unraveling specialization within a species or among morphologically identical species might be problematic without the use of molecular marker. In this chapter, we discuss how polyDNAviruses are linked to the process of specialization in braconid and ichneumonid wasps and are hence very good markers of wasp specialization. We also review how they are involved in the fine mechanism of specialization.
