Variation in intrinsic resistance of pea aphids to parasitoid wasps: A transcriptomic basis Open
Evolutionary interactions between parasitoid wasps and insect hosts have been well studied at the organismal level, but little is known about the molecular mechanisms that insects use to resist wasp parasitism. Here we study the interactio…

Intraspecific variation in symbiont density in an insect-microbe symbiosis Open
A bstract Many insects host vertically-transmitted microbes, which can confer benefits to their hosts but are costly to maintain and regulate. A key feature of these symbioses is variation: for example, symbiont density can vary among host…

Multiple phenotypes conferred by a single insect symbiont are independent Open
Many microbial symbionts have multiple phenotypic consequences for their animal hosts. However, the ways in which different symbiont-mediated phenotypes combine to affect fitness are not well understood. We investigated whether there are c…

Host relatedness influences the composition of aphid microbiomes Open
Animals are host to a community of microbes, collectively referred to as their microbiome, that can play a key role in their hosts' biology. The bacterial endosymbionts of insects have a particularly strong influence on their hosts, but de…

Intrinsic pre-zygotic reproductive isolation of distantly related pea aphid host races Open
Human activities may weaken or destroy reproductive isolation between young taxa, leading to their fusion with consequences for population and community ecology. Pea aphid host races are adapted to different legume taxa, providing a degree…

Do facultative symbionts affect fitness of pea aphids in the sexual generation? Open
Many aphids carry one or more facultative symbiotic bacteria which can provide a variety of fitness benefits for their hosts. They have chiefly been investigated in asexually reproducing aphids, with studies of the sexual generation limite…

Cascading effects of herbivore protective symbionts on hyperparasitoids Open
1. Microbial symbionts can play an important role in defending their insect hosts against natural enemies. However, researchers have little idea how the presence of such protective symbionts impacts food web interactions and species divers…

Consequences of symbiont co‐infections for insect host phenotypes Open
Most animals host communities of symbiotic bacteria. In insects, these symbionts may have particularly intimate interactions with their hosts: many are intracellular and can play important roles in host ecology and evolution, including pro…

Establishment and maintenance of aphid endosymbionts after horizontal transfer is dependent on host genotype Open
Animal-associated microbial communities have important effects on host phenotypes. Individuals within and among species differ in the strains and species of microbes that they harbour, but how natural selection shapes the distribution and …

Genotype specificity among hosts, pathogens, and beneficial microbes influences the strength of symbiont‐mediated protection Open
The microbial symbionts of eukaryotes influence disease resistance in many host-parasite systems. Symbionts show substantial variation in both genotype and phenotype, but it is unclear how natural selection maintains this variation. It is …

The outcome of competition between two parasitoid species is influenced by a facultative symbiont of their aphid host Open
Summary Symbiotic bacteria can act to protect their host against natural enemies. Where this protection is asymmetric against different natural enemies, protection conferred by symbionts has the potential to mediate interactions between na…

Summary Eukaryotes commonly host communities of heritable symbiotic bacteria, many of which are not essential for their hosts' survival and reproduction. There is laboratory evidence that these facultative symbionts can provide useful adap…

Defensive insect symbiont leads to cascading extinctions and community collapse Open
Animals often engage in mutualistic associations with microorganisms that protect them from predation, parasitism or pathogen infection. Studies of these interactions in insects have mostly focussed on the direct effects of symbiont infect…
