“…Evidently, Ni uptake of HI depends on the growth substrate, and this result should be further investigated. The BAF <1 for Ni agrees with the observations of Sun et al (2007) [69]: they demonstrated that pupae and adults of Spodoptera litura did not accumulate Ni. Moreover, they observed that Ni concentrations in pupae and adults were significantly lower than those in larvae, which indicated that the excessive nickel might be excreted during metamorphosis, as observed also for the other PTEs indagated.…”

Black soldier fly (Hermetia illucens, HI, Diptera, Stratiomydae) has great potential as a food and feed ingredient in the European Union (EU). The production of insects as livestock feed or as food ingredients requires strict monitoring of the content of potentially toxic elements (PTEs) in the growth substrate, to meet the security requirements. This study aims to investigate the presence of PTEs, like cadmium, lead, mercury, arsenic, and nickel, in HI prepupae and in their growth substrates based on coffee roasting by-product and microalgae Schizochytrium sp. and Isochrysis sp. Analyses were carried out via graphite furnace atomic absorption spectrophotometry for Cd, Pb, Ni, and As, and via Direct Mercury Analyzer for Hg. All element concentrations found in growth substrates were below the legal limit of undesirable substances in animal feed (2002/32/EC). Elements concentrations in HI prepupae were in the range (mg kg−1 wet weight) of 0.072 to 0.084 for Cd, 0.018 to 0.026 for Pb, 0.010 to 0.032 for Hg, 0.036 to 0.047 for As, and 0.18 to 0.76 for Ni. Even if HI prepupae accumulated Cd, Pb, and Hg, our results indicated that the risk of exposure to PTEs from HI prepupae consumption is relatively low and in compliance with EU regulations.

“…In the previous studies, we found that the survival rate of S. litura larvae fed on the diets treated with more than 5 mg/kg nickel was significantly decreased [17] , apoptosis of hemocytes of 6th instar larvae was inhibited and energetic contents in the hemolymph was reduced. Undoubtedly, the development of S. litura larvae was severely affected by higher doses of nickel (unpublished data).…”

Metallothionein expression induced by nickel accumulation in the midgut of Spodoptera litura Fabricius larvae was investigated by exposing S. litura larvae to the artificial diets amended with different doses of nickel for 3 generations. Nickel accumulations in the midgut of 6th instar larvae were detected by Inductively Coupled Plasma-Atomic Emission Spectrometer (ICP-AES), and the induced metallothionein expression in the midgut of 5th and 6th instar larvae in 120 h were quantified using cadmium-hemoglobin total saturation methods. The accumulated nickel in the midgut of the 6th instar larvae within a generation increased with the increase of the nickel doses in the treated diets and showed significant dose-dependence with the nickel doses in diets. Metallothioneins induced by nickel accumulated in the larval midgut also increased with nickel doses in diets and with the increasing stressing time in a generation. Results also suggested that the metallothionein expression was different with the time of S. litura larvae stressed by nickel.nickel, Spodoptera litura, midgut, accumulation, metallothionein Metallothionein (MT) is a family of ubiquitous cysteine-rich protein binding heavy metals with a low molecular weight. Apart from the role of MTs in trace element storage, transportation and metabolism, MTs are also involved in a number of biological processes, such as protection against ionizing radiation and oxidative damage caused by free radical, especially in the processes of heavy metal detoxification and tolerance [1] . MT expression in different tissues could be induced by exposing organisms to the polluted environment by heavy metals.Nickel is one of the heavy metals that induce some animals to express MT. For example, MT concentrations in the kidneys of Coregonus clupeaformis (Mitchill) and Salvelinus namaycush (Walbaum) significantly increased with feeding diets containing excessive nickel [2] . Perca flavescens (Mitchill) also increases MT amount against the oxidation induced by nickel accumulation in the animal [3] .There were a few reports concerning the effects of heavy metals on the MT expression in insects. It was found that MT could be induced by some heavy metals, such as Cu, Zn, Cd and Pb in some insects of Collembulous Orchesella cincta (L.), Dipterous Drosophila melanogaster (L.), Musca domestica (L.) and Boettcherisca peregrina (Robineau-Desvoidy) [4] . High level MT expression was induced by Cd, Cu and Zn stress in the larvae of Culex quinquefasciatus (Say), and by Cd stress in the larvae of O. cincta [5,6] . The tolerance of D. melanogaster to Cu and Cd was apparently correlated with replication of MT gene [7] . Though MT gene of Bombyx mori (L.) was expressed in E. coli by random clone [8] , there were no reports concerning the impacts of

“…Potential mechanisms for the elevated mortality of late‐instar larvae may include the accumulation of trace heavy metals in larvae by cumulative consumption (Sun et al., ), desiccation or cuticle damage as occurs with inert Diatomocaeous Earth (Korunić, ), or the cost of mandibular wear from consuming abrasive surfaces (Ennis, Mader, Burnside, Bauce, & Despland, ; Kyi, Zalucki, & Titmarsh, ). High larval mortality in the first 10 days of the experiment was likely due to (a) high background mortality of second instars that are at a more vulnerable life stage and (b) the shock of transferring from undefended and nutritionally balanced laboratory diet to relatively low‐quality leaf material and (c) intraspecific competition between neonates grouped in survival tests.…”

Coalmines, which are major contributors of particulate matter in the form of coal dust, are expanding globally into rural environments. However, ecological effects on organisms interacting with coal‐dusted foliage in mining landscapes are unknown. We tested how the behaviour, development and survival of a polyphageous insect herbivore, Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) is affected by consuming tomato leaves Lycopersicon esculentum laden with coal dust. We tested (a) feeding site establishment preference of neonates, (b) feeding behaviour and leaf consumption of late‐instar larvae, (c) survival of neonates and (d) survival and development of late‐instar larvae. We found that coal dust consumption increased the mortality of late‐instar larvae but did not influence their development. Despite long‐term implications for survival, late‐instar larvae did not adjust their feeding behaviour or the amount of leaf material consumed in response to foliar coal dust. Contrastingly, when neonate H. armigera were given a choice, they avoided establishing themselves on the coal‐dusted adaxial surface of leaves. Neonate mortality was 99% within 7 days, with no effect of coal dust. Our study provides the first data on the impact of coal dust on an insect herbivore. This has implications for ecological interactions in landscapes adjoining coalmines.
