- Abstract
- Insects host a wide range of bacteria, some of which are heritable and have major impacts on their evolutionary ecology, with consequences for host–parasitoid relationships. Climate change is expected to have a significant impact on host–parasitoid and host–symbiont relationships, but these two axes are rarely considered together. We address this issue by focusing primarily on aphids, aphid parasitoids and the diversity of their heritable symbionts. We outline the diversity of bacterial symbionts that coevolve with crop pests and parasitoid wasps and discuss the influence of temperature on bacteria–insect symbiosis. Along the way, we discuss various hypotheses and predictions on how increasing temperature in a context of climate change, by influencing endosymbionts, may affect host–parasitoid relationships and biological control programmes. This critical synthesis suggests new avenues to delve into and should serve as a roadmap for further exploration of the complexity of the host–microbiota–parasitoid network in a context of global warming.
