Costs and benefits of ant attendance to the drepanosiphid aphid Tuberculatus quercicola
TLDR
It is hypothesized that ant-attended aphids are under intense selective pressures that act against aphid clones which fail to attract many ants, so that aphids have developed an adaptive mechanism to allocate a larger fraction of resources to the honeydew when they are requested to do so by the ants in order to ensure the ants' consistent visitation. Expand
Aphid galls accumulate high concentrations of amino acids: a support for the nutrition hypothesis for gall formation
TLDR
It is suggested that S. chaetosiphon galls function to promote the breakdown of leaf protein, leading to an increased performance of gall‐inhabiting aphids. Expand
Flexibility in the composition and concentration of amino acids in honeydew of the drepanosiphid aphid Tuberculatus quercicola
TLDR
Mutualistic interactions between aphids and ants are mediated by honeydew that aphids produce, and nymphs of the aphid Tuberculatus quercicola developed into significantly smaller adults with lower fecundity than did nymphS that were not ant attended. Expand
Ant attendance changes the sugar composition of the honeydew of the drepanosiphid aphid Tuberculatus quercicola
TLDR
It is suggested that the increase in the proportions of sucrose and trehalose in honeydew leads to a shortage of carbohydrates available for energy metabolism, resulting in lower performance of the aphids under ant attendance. Expand
Mitochondrial phylogenomics and genome rearrangements in the barklice (Insecta: Psocodea).
TLDR
The tree estimated from the mitochondrial genomic data was well resolved, strongly supported, and in agreement with previously estimated phylogenies, and provided the first robust support for the family Prionoglarididae, as its monophyly was uncertain in previous morphological and molecular studies.

Introducing wood ants: evolution, phylogeny, identification and distribution
TLDR
This chapter describes species that are currently considered members of the subgenus Formica sensu stricto ; their evolution, identification, habitat and distribution, and the concept of red wood ants as social insects is introduced. Expand

TLDR
The honeydew of ant-attended aphids contains melezitose (a trisaccharide), which has an important role in aphid-ant interactions, and cuticular hydrocarbons on aphids and ants have clarified the underlying mechanisms of ant predation on aphid populations. Expand
Genetic architecture for normal and novel host‐plant use in two local populations of the herbivorous ladybird beetle, Epilachna pustulosa
TLDR
The results suggest that the host‐range is not restricted by the antagonistic genetic associations among exploitation abilities on different plant species, but rather that selection of different host‐plants may improve the coordination between genes responsible for the use of different plants.

TLDR
It is shown that flight apparatus was more developed in aphids under ant-exclusion conditions, which may imply that T. quercicola fly when ants are not available, and that aphids produce honeydew at the expense of resource investment in flight apparatus. Expand
Contrasting patterns of genetic structure and dispersal ability in ant-attended and non-attended Tuberculatus aphids
  • I. Yao

  • 23 April 2010
TLDR
It is suggested that populations of ant-attended aphids are composed of fragmented local subpopulations that are connected by low dispersal rates, leading to considerable population differentiation. Expand
