The influence of genetic variation on pre‐oviposition processes for host‐parasitoid co‐evolution

Ecological Entomology, Volume 50, Issue 1, Page 1-16, February 2025.
Co‐evolution between aphid hosts and their parasitoids has been associated with adaptative pressures linked with aphid physiological resistance (related to aphid and their endosymbionts' genetic variation) and parasitoid virulence. The aphid‐parasitoid interaction is composed of multiple previous stages before parasitoid oviposition that has been ...
