1. Many insects host secondary bacterial symbionts that are known to have wide‐ranging
effects on their hosts, from host‐plant use to resistance against natural enemies. This has …

Recent research has shown that the bacterial endosymbionts of insects are abundant and
diverse, and that they have numerous different effects on their hosts' biology. Here we …

Intraspecific variation in dietary breadth can influence important ecological and evolutionary
processes, yet the mechanisms generating this variation are usually unknown. Maternally …

1. Infection by the bacterial endosymbiont Hamiltonella defensa is capable of protecting the
pea aphid from parasitism by Aphidius ervi and the black bean aphid from parasitism by …

BACKGROUND Aphids are agricultural pests that damage crops by direct feeding and by
vectoring important plant viruses. Bacterial symbionts can influence aphid biology, eg by …

Microbial organisms are ubiquitous in nature and often form communities closely associated
with their host, referred to as the microbiome. The microbiome has strong influence on …

Many insects are associated with heritable symbionts that mediate ecological interactions,
including host protection against natural enemies. The cowpea aphid, Aphis craccivora, is a …

Previous studies have shown that Regiella insecticola modulated the parasitism rate in
wheat aphid, Sitobion miscanthi. However, little is known about influences of the symbiont …

Spider mites are frequently associated with multiple endosymbionts whose infection patterns
often exhibit spatial and temporal variation. However, the association between …

The target of natural selection is suggested to be the holobiont-the organism together with its
associated symbiotic microorganisms. The well-defined endosymbiotic communities of …
