TLDR
Parallels between the mechanism of aphid-plant and pathogen-plant attack are pointed out and how aphid bacterial endo-symbiotes play a central role in host-plant selection.
Abstract
The importance of host-plant resistance of crop plants in the biological control of aphids and the formation of aphid biotypes is discussed. The rapid response of plant breeders to the formation of new aphid biotypes requires detailed knowledge on the mechanism of host-plant resistance. Current knowledge on the chemical basis of host-plant resistance to aphids is summarized. Of central importance to this relationship is the aphid-pectinase plant-pectin interdependence. Parallels between the mechanism of aphid-plant and pathogen-plant attack are pointed out and how aphid bacterial endo-symbiotes play a central role in host-plant selection.

Nutritional Interactions in Insect-Microbial Symbioses: Aphids and Their Symbiotic Bacteria Buchnera

TL;DR: It is argued that strong parallels may exist between the nutritional interactions (including the underlying mechanisms) in the aphid-Buchnera association and other insect symbioses with intracellular microorganisms.

Fine structure of aphid stylet routes in plant tissues in correlation with EPG signals.

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.

The Chemical Ecology of Aphids

TL;DR: Study of aphid chemical ecology involving volatile semiochemicals, particularly pheromones, has been greatly enhanced by the development of electrophysiological rccordings from aphid antennae, using the electroan­ tennograph (EAG) and single-cell recording (SCR) methods.

Structure, expression, and antisense inhibition of the systemin precursor gene

TL;DR: Tomato plants transformed with an antisense prosystemin complementary DNA exhibited greatly suppressed systemic wound induction of proteinase Inhibitor I and II synthesis in leaves.

Arabidopsis Transcriptome Changes in Response to Phloem-Feeding Silverleaf Whitefly Nymphs. Similarities and Distinctions in Responses to Aphids

TL;DR: Analysis of SLWF performance on wild-type and phytoalexin-deficient4 (pad4) mutants suggests aphid and SLWF interactions with Arabidopsis were distinct and provides a more comprehensive understanding of phloem-feeding insect-plant interactions.

Structure and properties of pectin gels in plant cell walls

TL;DR: The structural characterization of pectins and the gels which they form, in relation to auxin-induced extension growth, the ripening of fruit, and cellular recognition are discussed in this article.

An Evolutionary and Applied Perspective of Insect Biotypes

TL;DR: A classification system of insect biotypes, based on the mechanisms underlying their differentiation, is outlined below, and the significance of biotypes in adaptation, speciation, and pest management is considered.

Plant penetration by feeding aphids (Hemiptera, Aphidoidea): a review

TL;DR: The factors responsible for determining the host-plants and feeding sites of aphids, and the various probing activities (the role of the labium, stylet insertion, surface saliva deposition, the behaviour of the aphid, virus transmission) are examined.
