SummaryWe examined the capacity of the galling aphid, Pemphigus betae, to manipulate the sink-source translocation patterns of its host, narrowleaf cottonwood (Populus angustifolia). A series of 14C-labeling experiments and a biomass allocation experiment showed that P. betae galls functioned as physiologic sinks, drawing in resources from surrounding plant sources. Early gall development was dependent on aphid sinks increasing allocation from storage reserves of the stem, and later development… 
A genetic basis for the manipulation of sink–source relationships by the galling aphid Pemphigus batae
TLDR
The importance of including plant genetics in future studies of the manipulation of translocation patterns by phytophageous insects is argued, suggesting strong genetic control of sink–source relationships.
A Complex Nutrient Exchange Between a Gall-Forming Aphid and Its Plant Host
TLDR
The metabolic efficiency of this self-circulating system indicates that the input needed from the host plant to maintain aphid population growth less than previously thought and possibly minimal, and the recycling of nutrients from aphid-gall tissues via photosynthesis and glycometabolism.
Gall-forming aphids are protected (and benefit) from defoliating caterpillars: the role of plant-mediated mechanisms
TLDR
Experimental support for the gall defense hypothesis is provided, finding that the aphid that forms galls on Pistacia atlantica leaves, is fully protected from destruction by the folivorous processionary moth.
Woody Stem Galls Interact With Foliage to Affect Community Associations
TLDR
It is shown that gall leaves are important for stem gall development, quality, and defenses, adding support for the nutrient and enemy hypotheses.
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.
Photosynthesis and sink activity of wasp-induced galls in Acacia pycnantha.
TLDR
The ability of the wasps to cause gall formation in vegetative tissues tempers intraspecific competition and substantially increases the availability of plant resources for the development of wasps in such galls is concluded.
Plant organ abscission and the green island effect caused by gallmidges (Cecidomyiidae) on tropical trees
TLDR
The adaptive nature of plant organ abscission as a plant defense against gallers and as a gall inducer adaptive trait is discussed.
Leaf-derived cecidomyiid galls are sinks in Machilus thunbergii (Lauraceae) leaves.
TLDR
Results strongly indicate that leaf-derived cecidomyiid galls are sinks in Machilus thunbergii leaves, however, it is perplexing how larvae cycle and balance CO(2) and O( 2) in gall growth chambers without stomata.
Effects of Gall Formation by Neothoracaphis yanonis (Hemiptera : Aphididae) on Shoot,Fruit,and Seed Production of Its Host Plant,Distylium racemsum (Hamamelidaceae)
TLDR
Effects of leaf gall formation by Neothoracaphis yanonis on the growth and reproduction of its host plant, Distylium racemosum, were studied in a viewpoint of sink-source relationship.
Effects of Gall Induction by Epiblema Strenuana on Gas Exchange, Nutrients, and Energetics in Parthenium Hysterophorus
TLDR
The observed effects demonstrate that E. strenuana has the potential to regulate P. hysterophorus, and gall induction reduces the leaf-water potential and reduced rates of photosynthesis, transpiration, and stomatal conductance in galled plants.

HOW APHIDS CHOOSE LEAVES: THE ROLES OF PHENOLICS IN HOST SELECTION BY A GALLING APHID'
TLDR
In a comparison between two neighboring trees that are differentially infested with colonizing aphids, the tree with the higher aphid numbers per leaf has lower phenol levels in its leaves, suggesting that phenol gradients play a role in microhabitat selection.
Conversion of mature leaves into sinks on the dicotyledonous C4 plants Amaranthus caudatus and Gomphrena globosa
The effect of an artificially created sink leaf on translocation of 14C-labeled assimilates from a source leaf of the C4 plants Amaranthus caudatus L. and Gomphrena globosa L. was studied with
Resource Regulation by a Stem‐Galling Sawfly on the Arroyo Willow
TLDR
A model of gall—induced resource maintenance the resource regulation hypothesis, where heavy Euura galling maintains willows at a young, relatively susceptible juvenile stage and increasing branch age of lightly galled clones confers resistance to galling.
PREMATURE LEAF ABSCISSION: AN INDUCED PLANT DEFENSE AGAINST GALL APHIDS'
TLDR
It is revealed that premature leaf abscission is induced by gall aphid attack, and galling aphid species are 3.5 times as likely to host-shift as nongalling aphids, and this may explain why sessile plant pests should be particularly susceptible to induced leaf Abscission.
Leaf Demography and Plant-Insect Interactions: Goldenrods and Phloem-Feeding Aphids
TLDR
The relationship between leaf demographic parameters in goldenrods (Solidago canadensis L.) and the choice of feeding sites by phloemfeeding aphids is reported and it is suggested that the demography of plant parts may have an important influence on the interactions between plants and insect herbivores.
Habitat Selection by Pemphigus Aphids in Response to Response Limitation and Competition
TLDR
No leaf produced by the tree is so large that a further increase in leaf size would not result in an increase in fitness, thus, even at low competitor densities, resources would still be important in the habitat selection process and in determining the parasite distribution.
Why does the bud-galling sawfly, Euura mucronata, attack long shoots?
TLDR
The bud-galling sawfly attacked longer shoot length classes on its host, Salix cinerea, more frequently than shorter shoots, dictated by plant resistance and not by natural enemies.
Cost of Benefits of Territoriality: Behavioral and Reproductive Release by Competing Aphids
TLDR
Colonizing stem mothers of the gall—forming aphid Pemphigus betae defend galls sites on narrowleaf cottonwood, Populus angustifolia to establish microterritories 3—5 mm in length.
Consequences of host plant chemical and physical variability to an associated herbivore
TLDR
It is suggested that gallformers modify host plant biochemistry within willow galls, which may explain why the chemical parameters of ambient plant quality the authors tested were less predictive than plant growth.
