Research over the past 30 years has led to a widespread acceptance that insects establish
widespread and diverse associations with microorganisms. More recently, microbiome …

To understand insect abundance, distribution and dynamics, we need to understand the
relevant drivers of their populations and communities. While microbial symbionts are known …

Many animals have evolved associations with symbiotic microbes that benefit the host
through increased growth, lifespan, and survival. Some interactions are obligate (essential …

Facultative, heritable endosymbionts are found at intermediate prevalence within most
insect species, playing frequent roles in their hosts' defence against environmental …

When ecological and evolutionary dynamics occur on comparable timescales, persistence
of the ensuing eco-evolutionary dynamics requires both ecological and evolutionary …

Parasite‐mediated selection can rapidly drive up resistance levels in host populations, but
fixation of resistance traits may be prevented by costs of resistance. Black bean aphids …

The occurrence of facultative endosymbionts has been studied in many commercially
important crop pest aphids, but their occurrence and effects in non‐commercial aphid …

Highlights•Climate change will affect insect through their association with symbiotic
bacteria.•Mutualistic symbionts can determine the thermal tolerance of host insects.•Obligate …

Insects often harbour heritable symbionts that provide defence against specialized natural
enemies, yet little is known about symbiont protection when hosts face simultaneous threats …

Insect host–parasitoid interactions abound in nature and are characterized by a high degree
of host specialization. In addition to their behavioral and immune defenses, many host …
