Insect behavior and the microbiome

International audienceIncreasingly we are coming to understand the role of the microbiome in determining host physiological, behavioural, and evolutionary processes. Indeed it is now widely accepted that the host genome should be considered from a hologenomic point of view, with it also including the genomes of its symbiotic microbiota. Some of the most remarkable phenomena in the insect world relate to behavioural manipulation by the microorganisms associated with a host, and we here review recent progress in the study of these phenomena. The effects of the microbiome on insect hosts have important evolutionary consequences, and we are at the forefront of an exciting time in the study of manipulated insects
