“…Kramer et al (1996) reported that the amino acid histidine plays a pivotal role in hyperaccumulation of metals by an Alyssum species, including transport of metals in the xylem sap. Aphids are relatively sensitive to the quantitative and qualitative composition of amino acids in their diet (Mittler & Kleinjan 1970;Sandstrom 1994;Simpson et al 1995). In our preference experiment, we found that aphid population size per unit of plant biomass was highest on high-Ni plants, suggesting that Ni-stimulated changes in host plant quality favoured aphid population growth on those plants.…”

Nickel hyperaccumulation, resulting in plant Ni contents of \1000 mg kg −1 dry mass, has been shown to defend plants against folivorous herbivores. We determined whether this elemental defence tactic protected hyperaccumulating plants from attack by a phloem-feeding herbivore. We used the pea aphid, Acyrthosiphon pisum, and the Ni-hyperaccumulating plant Streptanthus polygaloides. Aphids were allowed to colonize mixed arrays of S. polygaloides in which plants either were hyperaccumulating Ni, not hyperaccumulating Ni and treated with a systemic insecticide, or not hyperaccumulating Ni. Aphid numbers g −1 dry mass of plant biomass were lowest for the insecticide treatment, intermediate for low-Ni plants, and highest for plants hyperaccumulating Ni. Artificial liquid aphid diet, amended with varying levels of Ni, resulted in decreased aphid survival at 2500 mg kg −1 Ni dry mass (or 5.03 mM Ni). We concluded that Ni levels in the phloem of hyperaccumulating plants of S. polygaloides were B5.03 mM and, as a result, were not effective in defending plants against aphid attack.

“…Auclair, 1963;Auclair, 1969;Mittler and Dadd, 1963;Simpson et al, 1995) have demonstrated that aphids perform best on diets that mimic the sucrose and pH composition of sieve-tube sap (pH values of approximately 7.0 and a high concentration of sucrose). A preference for similar diets in choice chambers (Mittler and Dadd, 1964;Hewer et al, 2010) indicates that aphids have the sensory means to identify sieve tubes in plant tissues (Hewer et al, 2010).…”

“…sucrose vs water, sucrose vs sucrose with amino acids) were compared to investigate diet preference (Mittler and Dadd, 1964) or uptake rates of diet solutes (Mittler and Dadd, 1962;Mittler and Dadd, 1963a). Later, an extensive series of amino acid/sucrose diets was employed to determine optimal growth conditions (Simpson et al, 1995).…”

SUMMARY The ability of aphids to detect and find sieve tubes suggests that aphids receive cues for sieve-tube recognition by taking samples. Specific natural conditions such as pH value, sugar species and concentration, viscosity, and oxygen pressure may enable sieve-tube detection. We tested the preference of Megoura viciae and Myzus persicae for potential plant-borne orientation parameters in artificial choice-chamber systems. Both species preferred sucrose (in comparison with fructose, glucose, raffinose or sorbitol) at concentrations of 15–22.5% (over a tested range of 0–22.5%) and at approximately pH 7 (over a tested range of pH 5–8). This preference matches the composition of the sieve-tube sap of their host plants. Likewise, Rhopalosiphum padi (normally found on barley plants with sucrose in the phloem sap) and Macrosiphum euphorbiae (normally found on pumpkin plants with raffinose-family oligosaccharides in the phloem sap) showed a significant preference for sucrose. In the absence of sucrose, however, M. euphorbiae strongly preferred raffinose. No clear preference for any carbohydrate was observed for Macrosiphum rosae and Aphis pomi (both normally found on plants with various amounts of sorbitol in the phloem sap). Electrical penetration graph (EPG) measurements of M. persicae feeding on artificial diets confirmed that sieve tubes are recognized solely by a combination of carbohydrate abundance and a neutral to slightly alkaline pH.
