Benefits and costs of hosting facultative symbionts in plant‐sucking insects: A meta‐analysis
Abstract Many animals have evolved associations with symbiotic microbes that benefit the host through increased growth, lifespan, and survival. Some interactions are obligate (essential for survival) while others are facultative (usually beneficial but not essential). Not all individuals host all facultative symbionts in a population, and thus there is
