Relationship between SO2 dose and growth of the pea aphid, Acyrthosiphon pisum, on peas
TLDR
The dose-response curve is discussed in relation to reported changes in the nitrogen metabolism of plants subject to air pollution, the response of aphids to host plant nitrogen and possible toxic effects of high concentrations of SO(2) on the aphid.About:

Invertebrates in urban areas: A review
TL;DR: Some of the trends in the abundance, diversity and richness of invertebrates related to urbanisation and the specific urban environmental and traffic factors which may be at play are discussed.
Journal ArticleDOI
The Role of Heavy Metals in Plant Response to Biotic Stress.
TL;DR: The present review discusses the impact of heavy metals on the growth of plants at different concentrations, paying particular attention to the hormesis effect, and issues relating to metal ion acquisition and ion homeostasis that may be essential for the survival of plants, pathogens and herbivores competing in the same environment.

Environmental effects on insects and their population dynamics
TL;DR: Insect’s immune responses as melanization, lysozyme level and phenoloxidase (PO) modify the physiology and morphological behavior against different factors like diets, gases and chemicals, which influence the insects and their population dynamics.

Diet-mediated effects of heavy metal pollution on growth and immune response in the geometrid moth Epirrita autumnata.
TL;DR: Both the relative growth rate (RGR) and pupal weight were significantly higher in control trees than on polluted trees, indicating that metal pollution prevented the insect from achieving maximal growth on birch leaves.
Journal ArticleDOI
Insects and plants in a changing atmosphere
TL;DR: This is the winter meeting for the year 2000, a year in which we all spent some time looking to the past as well as considering the opportunities and challenges of the future as discussed by the authors.

Herbivory in relation to plant nitrogen content
TL;DR: The evidence that N is scarce and perhaps a limiting nutrient for many herbivores, and that in response to this selection pressure, many Herbivores have evolved specific behavioral, morphological, physiological, and other adaptations to cope with and uti lize the ambient N levels of their normal haunts is examined.

Aphid growth and reproductive rates
TL;DR: In general, the greater the mean relative growth rate (MRGR) of apterous morphs of Rhopalosiphum padi (L.), the greater their fecundity.

A comparison of the reproduction of brevicoryne brassicae and myzus persicae in relation to soluble nitrogen concentration and leaf age (leaf position) in the brussels sprout plant
TL;DR: The value of total soluble nitrogen concentrations, based on analysis of leaf tissue, for indicating plant suitability for aphids is discussed as well as the difference in response of the two aphid species to experimental conditions favouring proteolysis in the leaf.

Factors in Resistance of Peas to the Pea Aphid, Acyrthosiphon pisum (Harr.) (Homoptera: Aphididae). II. Amino Acids
TL;DR: This is a report on the quantitative estimation of the free and total amino acid contents of the three susceptible varieties (Perfection, Daisy, and Lincoln) and the three resistant varieties (Laurier, Champion of England, and Melting Sugar) by the method of paper chromatography.

Air pollution increases Aphis fabae pest potential
TL;DR: Stimulatory effects of SO2 and NO2 and ambient London air on the growth of the black bean aphid, Aphis fabae, are shown and it is demonstrated that these have been mediated entirely via the host plant.
