“…Efficient regulation of Cd by predatory beetles, even at high soil amendments with fly ash, led them to maintain comparatively low Cd concentrations in their bodies (Scheifler et al, 2002; ACCEPTED MANUSCRIPT A C C E P T E D M A N U S C R I P T Wang et al, 2016). These data reinforce previous studies (Laskowski and Maryanski, 1993), indicating that transfer of metals in food chains doesn't depend only on storage forms (i.e.…”

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.

“…Nowadays, heavy metal pollution caused by mining, steel production, and electroplating has induced an adverse impact on the environment, which threatens the health of human beings and the stability of ecosystem [1]. Heavy metal ions can be accumulated through food chain, which is believed to be a risk for human beings even at trace level [2]. Additionally, heavy metal ions can affect cellular organelles, components, and induce oxidative stress.…”

“…In agricultural systems, plants persistently accumulate Cd from Cd-polluted soil and transfer Cd to higher trophic levels through the food chain [17]. Higher tropic-level consumers of crops, such as herbivorous insects, ingest Cd from their host plants and accumulate Cd [4,18].…”

Heavy metal pollution is becoming an increasingly serious problem in agricultural ecosystems. Heavy metals such as cadmium (Cd) accumulate in the food chain and may lead to detrimental effects on the physiological functions of living organisms, including herbivorous insects. One such example is the Asian Corn Borer, Ostrinia furnacalis (Lepidoptera: Pyralidae). However, how Cd can affect the development and reproduction of O. furnacalis is largely unknown. In this study, we exposed larvae of O. furnacalis to a diet containing Cd and investigated the effects of Cd on the development, mating behavior, and fecundity of the insect. We showed that Cd accumulates in the larvae and inhibits development by extending larval and pupal duration and decreasing the survival rate. The excretion of Cd through multiple routes during the larval and pupal stages resulted in low levels of residual Cd in the adult insects, which were not fed with Cd. However, the mating behavior and fecundity of these insects were significantly affected, compared to control insects. This suggests that the bioaccumulation of heavy metals such as Cd has long lasting and detrimental effects on O. furnacalis over the entire life cycle, affecting fecundity, even when specimens are only exposed at an early life stage.
