The ovipositor of parasitoid hymenoptera: how micro-surgery is inspired by nature’s inventions
By Pascal ROUSSE In the world of parasitoids (lire this article), the ovipositor, also called oviscapte (abdominal appendix with which eggs are deposited), has a crucial role since it allows to locate precisely the egg laying in space and time, which is essential when it has to match the biological cycle of the host. Before…
