..., phloem sap is a nutritionally unbalanced diet for phloem-feeding insects. Therefore, aphids and other phloem feeders typically rely on microbial symbionts for the synthesis of essential amino acids. To investigate the metabolism of the four main transport amino acids by the pea aphid ( Acyrthosiphon...

...A. E. Douglas; D. R. G. Price; L. B. Minto; E. Jones; K. V. Pescod; C. L. M. J. François; J. Pritchard; N. Boonham SUMMARY Plant phloem sap is an extreme diet for animals, partly because of its high and variable sugar content. The physiological and feeding traits of the pea aphid Acyrthosiphon...

... aphid Sitobion avenae Fabricus was low-temperature acclimated by rearing for three generations at 10°C, the discriminating temperatures (temperature that results in approximately 20% survival after direct transfer from the rearing temperature to a sub-zero temperature for a period of 3 h), of first...

...A. J. Karley; A. E. Douglas; W. E. Parker SUMMARY To define plant `nutritional quality' for aphids, the causal basis of the variation in aphid performance between host plants of different developmental ages was explored using the aphids Myzus persicae and Macrosiphum euphorbiae on potato plants...

...A. F. G. DIXON; P. C. CROGHAN; R. P. GOWING 1. The adhesive force acting between the adhesive organs and substratum for a number of aphid species has been studied. In the case of Aphis fabae , the force per foot is about 10 μN. This is much the same on both glass (amphiphilic) and silanized glass...

.... Pulling forces were applied by progressively loading the aphid with weights. The pulvilli perform best on relatively smooth surfaces. Aphids are dislodged from the underside of polished glass by a mass of approx. 9–14mg (a pulling force of 8.8-13.7×10 −5 N). The claws cannot engage a completely smooth...
