Parasitoids rely on other insects for the development of their offspring. They oviposit in or on a host, which is progressively consumed during larval development. Both parasitoids and their hosts harbour diverse microbial symbionts that may influence the outcome of their interaction and contribute to the evolutionary arms race between them. Many parasitoids are associated with symbiotic viruses that are injected into the host during oviposition and suppress the host’s immune responses. In contrast, several herbivorous hosts carry bacterial symbionts that play various important functions, including resistance to parasitism. In this work, I aim to better understand how microorganisms influence and are influenced by host-parasitoid interactions.
