“…Nickel values have also been reported from Polyrhachis ants (Hymenoptera: Formicidae) associated with B. coddii, but those ants were also tending aphids that were feeding on the hyperaccumulator and so Ni in the ants may not solely have come from the ants' predacious activities. Even so, Ni concentrations of these ants were relatively low: 97 +g Ni/g reported by Boyd et al (2006a) and 85 +g Ni/g reported by Migula et al (2007).…”

“…Statistical comparison of the datasets of Wall and Boyd (2002) in Figure 1 (mean = 80 +g/g), and Boyd et al (2006a) in Figure 2 (mean = 540 +g/g), shows these means differ significantly (Mann-Whitney U-test, tied Z-value = 7.7, P < 0.000 1). There are several potential reasons for this difference.…”

“…This is certainly an important factor, and probably contributes to the variation in whole-body Ni concentrations of the high-Ni insects reported in Table 2. For example, gut contents are likely one reason why the same heteropteran (Spilostethus rivularis Germar: Lygaeidae), collected from Berkheya coddii by both Boyd et al (2006a) and Migula et al (2007), was reported by the latter as having only 24% of the Ni concentration found by Boyd et al (2006a). Migula et al (2007) allowed captured insects to reduce their gut contents by delaying their deaths for 1-2 days, whereas Boyd et al (2006a) killed captured insects immediately after collection.…”

“…But it is difficult to ascribe much significance to this fact because we have so few data from other carnivorous insects. Boyd et al (2006a) reported relatively low values of Ni (36 +g Ni/g) from mantids collected from the same Ni hyperaccumulator species (Berkheya coddii) as the R. neavei collected by Migula et al (2007). Nickel values have also been reported from Polyrhachis ants (Hymenoptera: Formicidae) associated with B. coddii, but those ants were also tending aphids that were feeding on the hyperaccumulator and so Ni in the ants may not solely have come from the ants' predacious activities.…”

The Wasp as a Terrestrial Indicator of Environmental Metal Composition: Evidence from Zimbabwe

We explored metal concentrations in wasps from 4 sites near Harare, Zimbabwe, on a 106 km west-east transect. We found elevated concentrations at 2 presumed-polluted sites (a platinum [Pt] mine and a known polluted lake) located near a metal-enriched geological feature (the Great Dyke). A site in urban Harare and a nature reserve served as reference. Only wasps from the 2 presumed-polluted sites had quantifiable Pt. For Cr, Ni, Mg, Se, Fe, Mn, and V, we report the highest concentrations in wasps yet published. Wasps from the presumed-polluted sites had significantly higher concentrations of most metals when compared with wasps from the reference sites, suggesting pollution as a source. Geology, however, differs between the sites. It is probable, therefore, that both geology and pollution contributed to the differences in metal concentrations. Because of its long and narrow dimensions (550 km long and 4-11 km wide), the Great Dyke offers opportunities for comparative studies. Because wasps form a complex part of the food web and ecology, studies on the transfer of metals to wasps' predators are needed, especially given that some birds specialize in feeding on hymenopterans. The rich diversity of wasps (>145 000 species worldwide) occupying multiple different trophic levels is a good indicator, and wasps have a rich potential to join other invertebrates as terrestrial indicators.

Biotransfer, Bioaccumulation and Effects of Herbivore Dietary Co, Cu, Ni, and Zn on Growth and Development of the Insect Predator Podisus maculiventris (Say)

et al. 2013

Increased metal availability in the environment can be detrimental for the growth and development of all organisms in a food web. In part, this toxicity is due to biotransfer or bioaccumulation of metals between trophic levels. We evaluated the survival, growth, and development of a generalist Hemipteran predator (Podisus maculiventris) when fed herbivorous prey (Spodoptera exigua) reared on artificial diet amended with Cu, Zn, Ni, and Co. Predator nymphs were fed S. exigua larvae raised on diet amended with sublethal (Minimum Sublethal Concentration or MSC) or lethal (Minimum Lethal Concentration or MLC) concentrations of each metal, as well as control diet. We determined if metals were biotransferred or bioaccumulated from the diet to herbivore and predator, as well as if predator growth or survival was affected by herbivore diet. Podisus maculiventris fed herbivores raised on MLC levels of both Cu and Zn took significantly longer to mature to adults, whereas their overall survival was not affected by prey diet metal concentration for any metal. Adult weights were significantly reduced for predators raised on herbivores reared on diets amended with the MLC of Cu and Zn. Copper and Zn were bioaccumulated from diet to herbivore and from herbivore to predator, whereas Ni was biotransferred (although concentrations decreased as trophic level increased). The pattern for Co was more complex, with biotransfer the main outcome. Our results show that availability of metals in a food web can affect growth and development of a hemipteran predator, and that metals are transferred between trophic levels, with metal-specific biotransfer and bioaccumulation outcomes.
