“…The difference between insect species could be due to their excretion capacity. For example, in the soil‐mulberry‐silkworm system, Pb transfer coefficients from the mulberry leaves to silkworm larvae were below one, meaning that there was a bio‐minimization process; however, the transfer coefficients from silkworm larvae to their feces ranged from 13.02 to 39.35, about 108–983 times higher than those during the leaf to larvae transfer 16 . It could be conjectured from these results that bio‐minimization could have occurred since most of the ingested Pb ingested by the silkworm larvae was excreted through its feces.…”

“…However, in a heavy metal pollution environment, non-hyperaccumulator plants will be able to accumulate heavy metals over a sustained period of time and eventually also expose phytophagous insects to heavy metal stress. 16 The enrichment and distribution of heavy metals in different parts of plants varies. 17 For most plants, root interception can partially alleviate the damage caused by heavy metal stress in the over-ground parts of plants, which may lead to a higher accumulation of heavy metals in roots than that in over-ground parts.…”

The development and physiological status of pest insects are important factors that affect the effectiveness of biological control. Current knowledge reveals that heavy metals can be transferred to phytophagous insects through food chains and cause various chronic toxicological effects on the growth and physiology of phytophagous insects. These findings potentially attribute heavy metal contamination to an environmental factor governing biocontrol efficiency against pest insects, pointing to an urgent demand to better understand the effects of heavy metal exposure on insect susceptibility to entomopathogenic microorganisms. Here we discuss the transfer characteristics of heavy metals along the food chains to phytophagous insects and conclude that heavy metal exposure may promote insect susceptibility to entomopathogenic microorganisms in the heavy metal‐contaminated regions. Furthermore, we propose a ‘combined effect’ hypothesis that combination of entomopathogenic agent and heavy metal stress can cause a much higher overall insect mortality than does the entomopathogenic agent or the heavy metal stress alone. This is a new and relatively unexplored area in the microbial‐based biocontrol research, which might have great potential for future optimization of biocontrol strategies against economically and ecologically important agricultural or forest pests in the heavy metal polluted areas. © 2020 Society of Chemical Industry

Small‐scale silvopasture: Addressing urban and peri‐urban livestock challenges in the United States with agroforestry practices

The growing urban and peri-urban populations around the world creates strain on food and environmental security. Alleviation of these stressors may be possible by enhancing regional food production and ecosystem services provided by urban and peri-urban agriculture (UPA). Despite the growing popularity of UPA in the United States, incorporating livestock in these settings is challenging. A review of the literature identified three key barriers to adoption of urban and peri-urban livestock keeping that have the potential to be ameliorated using agroforestry practices to facilitate integration: animal feed resources, water quality and nutrient cycling, and use of sites contaminated with heavy metals. A discussion focused on the solutions to those barriers resulted in two theoretical silvopasture systems; we propose one for the urban setting and another for the peri-urban setting. We have determined small-scale livestock keeping provides a potential strategy to meet the demands of growing urban and peri-urban environments, but sustainable and effective integration of livestock under these conditions must be considered to mitigate environmental risks associated with urban livestock keeping. Urban silvopasture has the potential to enhance specialty crop and niche food production in these environments. Future research should seek to better understand small-scale silvopasture at the whole-system level in a variety of resource contexts and with local species and practices.
