“…The biomagnification of Cd by mustard aphids in the present study suggests that they use this storagedetoxification mechanism. The Cd biomagnification reported by other workers (Crawford et al, 1995;Green et al, 2003;Alonso et al, 2009) also affirm that similar mechanisms also operate in other aphid species for this metal.…”

“…Thus, aphids may have regulated the Cd accumulation to some extent via eliminating this metal with honeydew (Dar et al, 2015a). In contrast, Crawford et al (1995) found that aphid species Aphis fabae had no such evolved mechanism to eliminate Cd with honeydew. The findings of the present study and those of Crawford et al (1995) suggest that regulation of Cd by this mechanism may vary with aphid species.…”

The present study investigates the extent of biotransfer and bioaccumulation of cadmium (Cd), lead (Pb) and zinc (Zn) from fly ash amended soil in mustard (Brassica juncea)-aphid (Lipaphis erysimi)-beetle (Coccinella septempunctata) food chain and its subsequent implications for the beetle. The soil was amended with fly ash at the rates of 0, 5, 10, 20 and 40% (w/w). Our results showed that the uptake of Cd, Pb and Zn from soil to mustard root increased with the increase in fly ash application rates, but their root to shoot translocation was relatively restricted. Increase in chlorophyll content and dry mass of mustard plant on treatments ≥ 20% even at elevated accumulation of Cd (1.67 mg kg -1 ), Pb (18.25 mg kg -1 ) and Zn (74.45 mg kg -1 dry weight) in its shoot showed relatively higher tolerance of selected mustard cultivar to heavy metal stress. The transfer coefficient (TC 1 ) of Cd from mustard shoot to aphid was always > 1, indicating that Cd biomagnified in aphids at second trophic level. But, there was no biomagnification of Cd in adult beetles at third trophic level. Zinc accumulation was 2.06 to 2.40 times more in aphids than their corresponding host shoots and 1.26-1.35 times more in adult beetles than their prey (aphids) on which they fed. Lead was only metal whose TC was less than 1 at both second and third trophic levels. The elimination of Cd via honeydew of aphids was most efficient as the ratio of metal in honeydew to aphid (ranging from 0.21 to 0.26) was higher than the Pb (0.16 to 0.20) and Zn (0.07 to 0.09). The statistically consistent (p > 0.05) biomass and predation rate of predatory beetles indicated that all levels of soil amendments with fly ash did not have any lethal or sub-lethal effects on beetles.

“…They may, therefore, be more likely to store/detoxify metals rather than excrete them when compared to other inverts. The literature reflects this possibility with high levels of biomagnification in aphids reported for Cd and Zn in particular (Merrington et al 1997b), although excretion in the honeydew is still an effective excretion mechanism for some trace metals, for instance Cu (Crawford et al 1995).…”

20The contamination of agroecosystems due to the presence of trace elements in commonly 21 used agricultural materials is a serious issue. The most contaminated material is usually 22 sewage sludge and the sustainable use of this material within agriculture is a major concern. 23This study address a key issue in this respect, the fate of trace metals applied to soil in food 24 chains. The work particularly addresses the transfer of Pb, which is an understudied element 25 in this respect and compares the transfer of Pb with two of the most labile metals, Cd and Zn. 26The transfer of these elements was determined from sludge amended soils in a food chain

When present at elevated levels in the environment, heavy metals are toxic for most organisms. However, so-called hyperaccumulator plants tolerate heavy metals and use chelators for their internal long-distance transport. Thus, phloem-sucking insects may come in contact with the chelated metals. In the present study, the effects of individual and combined heavy metals, zinc (Zn) and cadmium (Cd), as well as of common chelators, nicotianamine and phytochelatin, were investigated on the performance, preferences, and metal accumulation of the generalist aphid Myzus persicae, using artificial diets. Added Zn increased aphid growth, whereas Cd reduced the survival of aphids. Chelators had neither protective nor negative effects on aphids. The combination of the 2 heavy metals in chelated or nonchelated form caused a potentiation effect that led to an extinction of the aphids within less than 2 wk, before they could reproduce. Both Cd and Zn accumulated in the aphids, indicating a possible biomagnification. In choice assays, aphids preferred diets amended with Zn with or without nicotianamine compared to a control diet. In contrast, a Cd-containing diet led to neither attraction nor aversion. The present study provides insight into how mixtures of heavy metals and their chelators influence the life history of a generalist aphid. The results have implications for the use of phytoremediation to remove heavy metals from contaminated soils. Environ Toxicol Chem 2016;35:3023-3030. © 2016 SETAC.
