Abstract
Transfer of Ni and other trace elements in Ni-hyper-accumulating Berkheya coddii and its grazer, Chrysolina pardalina was studied on the basis of material from ultramafic soils, RSA, and laboratory feeding experiments. Analyses of Cl, K, Ca, Ti, Cr, Mn, Fe, Fe, Co, Cu, Zn, Br, Rb, and Sr were done using micro-particle-induced x-ray emission (PIXE), total x-ray fluorescence (TXRF) and AAS methods. Actively feeding Ch. pardalina may effectively eliminate consumed nickel, (bioaccumulation factor (BAF) for larvae 0.004; for imago 0.009), possibly due to low digestibility of food and specific anatomical features of the excretory system. During active development they are able to eliminate nearly all excessive amounts of this metal obtained from B. coddii leaves. Differences in Ni body levels in insects from two different sites kept on the same diet suggest that these populations are at different stages of development of adaptive mechanisms for elimination of this metal. Body burdens with Ni are comparable with the levels of Zn, for which the BAFs are 6.35 and 3.51 for larvae and adults respectively. Such strategy could be used only when food in natural conditions is not a limiting factor and a competition for food is weak due to a high sensitivity of other potential pests of B. coddii.
