“…Some studies have shown a negative impact of heavy metals on pollinator survival and reproduction, especially for butterflies (e.g. Nieminen et al ., ; Noret et al ., ; Shu et al ., ), but other studies suggest a lack of such an influence (Kevan, ; van Rossum et al ., ; Szentgyörgyi et al ., ). Evidence linking decreased survival of bees and heavy metals comes from laboratory‐based toxicity tests performed on the honey bee, Apis mellifera (Hymenoptera: Apidae), (Leita et al ., ) and contamination of honey bee products (Bogdanov, ).…”

Bees are one of the most important groups of pollinators in the temperate zone. Although heavy metal pollution is recognised to be a problem affecting large parts of the European Union, we currently lack insights into the effects of heavy metals on wild bee survival and reproduction. We investigated the impact of heavy metal pollution on the wild bee Osmia rufa (Hymenoptera: Megachilidae) by comparing their survival, reproduction and population dynamics along two independent gradients of heavy metal pollution, one in Poland and the other in the United Kingdom. We used trap nests to evaluate the response of fitness and survival parameters of O. rufa. To quantify the levels of pollution, we directly measured the heavy metal concentration in provisions collected by O. rufa. We found that with increasing heavy metal concentration, there was a steady decrease in number of brood cells constructed by females and an increase in the proportion of dead offspring. In the most polluted site, there were typically 3–4 cells per female with 50–60% dead offspring, whereas in unpolluted sites there were 8 to 10 cells per female and only 10–30% dead offspring. Moreover, the bee population growth rate (R0) decreased along the heavy metal pollution gradients. In unpolluted sites, R0 was above 1, whereas in contaminated sites, the values tended to be below 1. Our findings reveal a negative relationship between heavy metal pollution and several fitness parameters of the wild bee O. rufa, and highlight a mechanism whereby the detrimental effects of heavy metal pollution may severely impact wild bee communities.

“…across the cuticle, via spiracles or ingestion) can result in changes to the cellular ultrastructure and genetics of the insect; for example, expression of Vg mRNA was found to be downregulated and the accumulation of Vn in eggs reduced in response to metal pollution [18]. Shu also showed that high levels of Zn reduced the expression of Vg in Spodoptera litura and negatively affected its reproduction [39]. Gene expression profiles of insect can be used to distinguish different responses to toxins such as metals.…”

“…Five hundred milligrams of samples (dry weight) were digested in 10 ml of boiling nitric acid (65%) and 1 ml concentrated perchloric acid (BAKER ANALYZED reagent; Baker, Deventer, Holland) [39], [40]. When the fume was white and the solution was completely clear, the samples were cooled to room temperature.…”

“…Zn 2+ is a highly toxic metal which is widely dispersed in the environment, mainly as a result of animal activities, and affects selective neuronal death after transient global cerebral ischemia [37]. Zn is potentially toxic to organisms at concentrations which significantly exceeds physiological limits, and can affect insect reproduction [19], [38], [39]. Plant phytophagous insects and predators are an important part of the food chain in nature.…”

Inhibitional Effects of Metal Zn2+ on the Reproduction of Aphis medicaginis and Its Predation by Harmonia axyridis

BackgroundContamination, including metals, can disturb the reproductive processes of many organisms, including both prey and predatory insects. However, there is virtually no information on the effects of high level Zinc (Zn) pollution on aphids and ladybirds. The high concentrations of Zn2+ or Zn pollution inhibit reproduction in the phytophagous aphid, Aphis medicaginis, and the predatory ladybird Harmonia axyridis could provide important information.ResultsIt was observed in this study that Zn concentrations in Vicia faba (broad bean) seeds and seedlings in all Zn2+ treatments were significantly higher than that in the control group, and increased with increasing Zn2+ concentrations in the solution. The rate of reproduction in A. medicaginis declined significantly (p<0.05) over time in the five groups fed on broad bean seedlings treated with different concentrations of Zn2+ solution compared with the control group. These results showed that higher concentrations of Zn2+ significantly inhibited the reproductive capacity of A. medicaginis. We also cloned and identified a gene encoding vitellogenin (Vg) from A. medicaginis, which has an important role in vitellogenesis, and therefore, reproduction was affected by exposure to Zn2+. Expression of AmVg was reduced with increasing exposure to Zn2+ and also in the F1–F3 generations of aphids exposed to different Zn2+ concentrations. Predation by H. axyridis was also reduced in aphids exposed to high-levels of Zn2+. Similarly, ovipositioning by H. axyridis was also reduced.ConclusionsOur results suggest that Zn2+ can significantly affect the reproductive capacity of both A. medicaginis and its predator H. axyridis, the former through effects on the expression of AmVg and the latter through avoidance of aphids containing high levels of Zn2+.

“…Pandal et al, (1975) and Panda (1976) reported the antagonistic effect of zinc against yellow stem borer which resulted due to induced antibiosis effect of zinc and developing of hard pseudostem. Shu et al, (2009) reported excess Zn made expression of vitellogenin gene down regulated and caused poor accumulation of egg yolk, which led to reduction in egg numbers and failure of eggs to hatch. Thus, the present findings derived ample support from the finding of above workers, so far the dead heart and white ear head was concerned.…”
