“…In agreement, it has been reported that Phoridae [37], collembolans [38], and Linyphiidae [39] are able to develop and survive in metal polluted sites, suggesting that these taxa are less sensitive to the high concentrations of metals, low pH, and altitude conditions encompassed by the present study. Although the drying of the naturally polluted site during the dry season could represent a confounding factor, the CCA indicated that the effect of metal pollution superseded any potential impacts related to this event.…”

Because environmental pollution may add further stress to life at high altitude, the present study explored the effect of metal pollution on the macroinvertebrate community composition in Andean streams between 3,500 to 4,500 meters above sea level (masl) during wet and dry seasons. At polluted sites, showing a high conductivity and a low pH, metal concentrations (e.g., Al, 13.07 mg/L; As, 3.49 mg/L; Mn, 19.65 mg/L; Pb, 0.876 mg/L; Zn, 16.08 mg/L) ranged from 8-fold up to 3,500-fold higher than at reference sites. The cumulative criterion unit allowed quantifying the potential toxicity of metal mixtures at the contaminated sites. Principal component analysis of physical chemical variables showed that reference sites were more likely to be structured by transparency, water discharge, and current velocity, while polluted sites appeared to be determined by metals and conductivity. Canonical correspondence analysis indicated a strong influence of highly correlated metals in structuring invertebrate communities, which were dominated by dipterans, coleopterans, collembolans, and mites at polluted sites. At reference sites crustaceans, ephemeropterans, plecopterans, and trichopterans were the most representative taxa. We concluded that severe metal pollution induced changes in macroinvertebrate community composition in highaltitude Andean streams, with a replacement of sensitive taxa by more tolerant taxa. Yet relatively species-rich communities persisted under harsh conditions.

“…Megaselia scalaris , a common detritivore, has been known to develop on substances as diverse as human wounds and corpses 51 , 52 , modeling clay, and emulsion paint 53 , 54 . Their ability to grow and mature on these diets, with minimal effect on their survival, and their tolerance to heavy metals 42 makes any effect of pharmaceuticals at very low doses found in reclaimed water even more surprising. In our study, the females had no preference for untreated diets versus any treated diets.…”

“…This species will generally feed on a variety of decomposing plant and animal tissues, and acts as a vector of pathogens 39 , 41 . These insects are both fecund and hardy because females can lay over 650 eggs in 16 days and are tolerant of heavy metals 42 , 43 . The white, roughly football-shaped eggs, hatch after approximately 24 hours into white translucent larvae.…”

Drought, rising temperatures, and expanding human populations are increasing water demands. Many countries are extending potable water supplies by irrigating crops with wastewater. Unfortunately, wastewater contains biologically active, long-lived pharmaceuticals, even after treatment. Run-off from farms and wastewater treatment plant overflows contribute high concentrations of pharmaceuticals to the environment. This study assessed the effects of common pharmaceuticals on a cosmopolitan saprophagous insect, Megaselia scalaris (Diptera: Phoridae). Larvae were reared on artificial diets spiked with contaminants of emerging concern (CECs) at environmentally relevant concentrations. Female flies showed no oviposition preference for treated or untreated diets. Larvae exposed to caffeine in diets showed increased mortality, and larvae fed antibiotics and hormones showed signs of slowed development, especially in females. The normal sex ratio observed in M. scalaris from control diets was affected by exposure to caffeine and pharmaceutical mixture treatments. There was an overall effect of treatment on the flies’ microbial communities; notably, caffeine fed insects displayed higher microbial variability. Eight bacterial families accounted for approximately 95% of the total microbes in diet and insects. Our results suggest that CECs at environmentally relevant concentrations can affect the biology and microbial communities of an insect of ecological and medical importance.

“…With imagoes the content of manganese decreased to 0.5% of the consumption even under maximum concentrations. Sorensen et al (2009) studied the survival rate of a cosmopolitan insect Megaselia scalaris (Loew, 1866), exposed to a Mn concentration of 2,600 mg kg -1 of dry mass. The insects with a diet Mn 260-2,600 mg kg -1 showed a significant decrease in the duration of their larval development, total duration of imago formation and breeding.…”

Martynov, V.O., Brygadyrenko, V.V., 2018. The impact of some inorganic substances on change in body mass of Tenebrio molitor (Coleoptera, Tenebrionidae) larvae in a laboratory experiment. Folia Oecologica, 45: 24-32.Addition of low concentrations of metal ions to the diet of saprophagous insects can impact on their metabolism over a short period of time, causing an increase or decrease in their body mass. This article presents a 14-day laboratory experiment evaluating the changes in the body mass of larval stage 3 of Tenebrio molitor (Linnaeus, 1758) induced by adding different inorganic substances (350 mg kg -1 of dry fodder) to the diet of the larvae. Following the addition of inorganic substances to the fodder, the most marked differences compared to the control were observed in the groups which consumed substrate with lead nitrate (the mass of the larvae increased on average by 102.6% compared to increase in mass in the control variant of the experiments), cobalt nitrate (by 96.9%), calcium chloride (by 89.1%) sodium triphosphate (by 86.0%), zinc chloride (by 83.5%). A nonsignificant effect (a tendency of increase in the body mass) on T. molitor larvae was caused by manganese sulfate (by 57.8%), aluminium nitrate (by 57.3%), iron oxide (by 51.5%), barium nitrate (by 47.9%), orthophosphoric acid (by 47.4%), manganese chloride (by 46.5%), calcium carbonate (by 27.7%), iron sulfate (by 24.2%) and ammonium heptamolybdate (by -7.5%). Therefore, 5 out of the 15 studied inorganic substances significantly stimulated the increase in the body weight of T. molitor larvae, and 7 manifested these capacities at the level of tendency (stimulated an increase in body weight averaging 43-58% over the 14-day experiment). The obtained data indicate a necessity for further study on the impact of inorganic pollutants on different stages of insects.
