TLDR
In this article I review the specialized characteristics of galling aphids, as well as their complex and diverse life histories, as reported in the past 20 years.Abstract:
Gall-inducing aphids are host specific in the gall stage. Most species alternate between trees (the primary host), where the gall is induced, and shrubs and grasses (secondary hosts). Parthenogenesis during most of their life cycle is interrupted by a single stage of sexual reproduction on the primary host. Apart from these general characteristics, galling aphids present some of the most complex and diverse life histories in the insect world. In this article I review the specialized characteristics of galling aphids, as well as their complex and diverse life histories, as reported in the past 20 years.read more

Plant-aphid interactions: molecular and ecological perspectives.
TL;DR: The same model systems that are used to explore direct molecular interactions between plants and aphids can be utilized to study the ecological context in which they occur.

The conflicting relationships between aphids and men: a review of aphid damage and control strategies.
TL;DR: The main control strategies are reviewed in the light of an integrated pest management approach for cereal aphids, which are among the most important in Europe as direct feeders and virus vectors.

Aphid-plant interactions: a review
TL;DR: This review summarizes the main aspects of plant-aphid interactions, focusing on those issues that can have an economic application and takes advantage of different types of resistance in order to enhance the sustainable control of these phytophagous insects.

Leaf-galling phylloxera on grapes reprograms host metabolism and morphology
TL;DR: The gall-forming aphid-like parasite phylloxera, Daktulosphaira vitifoliae, inducesStomata on the adaxial surface of grape leaves where stomata typically do not occur, which suggest a significant manipulation of primary metabolism and the subsequent changes in downstream secondary metabolism.
Journal ArticleDOI
Adaptive radiation of gall-inducing insects
TL;DR: The gall-inducing aphids on Pistacia in Israel show radiation into many adaptive zones, with different gall types and galling sites on the host plant, even though the radiation is much less extensive than in sawflies and gall wasps.

The Evolutionary Maintenance of Alternative Phenotypes
TL;DR: Polyphenism may be restricted to circumstances in which the developmental switch occurs during very early development, and the abundance of seasonal polyphenisms in multivoltine organisms suggests that where environments are favorable, developmental systems are often flexible enough for the establishment of simple polyphenism.

Fine structure of aphid stylet routes in plant tissues in correlation with EPG signals.
W.F. Tjallingii,Th. Hogen Esch +1 more
TL;DR: Two completely serially sectioned probes from the epidermis to the phloem were reconstructed and severed stylets in the plant tissue were processed for transmission electron microscopy (TEM) and sectioned either transverse or longitudinal to the stylets.
Journal ArticleDOI
Adaptive Nature of Insect Galls
TL;DR: The evolution of the galling habit has followed two pathways, one via mining plant tissues and the other from sedentary external herbivores that then modify plant growth.

TL;DR: Measurement of genetic variation in corals along Australia's Great Barrier Reef to determine the relative contributions of sexual and asexual reproduction to recruitment and to infer levels of gene flow found substantial genotypic diversity at local scales in six of the nine species.
