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

重金属沿食物链的转移：关于重金属胁迫下昆虫对昆虫致病性微生物敏感性的迷你综述

害虫的发育和生理状况是影响生物防治有效性的重要因素。当前的知识表明，重金属可通过食物链转移到食植物昆虫上，并对食植物昆虫的生长和生理产生各种慢性毒理作用。这些发现可能将重金属污染归因于一个环境因素，该环境因素控制着对害虫的生物防治效率，这表明迫切需要更好地了解重金属暴露对昆虫对病原微生物的敏感性的影响。在这里，我们讨论了重金属沿食物链向植食性昆虫的转移特征，并得出结论，重金属的暴露可能会促进重金属污染地区昆虫对昆虫病原微生物的敏感性。此外，我们提出了一个“联合效应”假设，即昆虫病原体和重金属胁迫的组合比单独的昆虫病原体或重金属胁迫可导致更高的总体昆虫死亡率。这是基于微生物的生物防治研究中一个相对较未开发的新领域，对于重金属污染地区中针对具有经济和生态意义的重要农业或森林有害生物的生物防治策略的未来优化可能具有巨大潜力。©2020化学工业协会我们提出了一种“联合效应”假设，即与致病原药或仅重金属胁迫相比，昆虫病原体与重金属胁迫的组合可导致更高的总体昆虫死亡率。这是基于微生物的生物防治研究中一个相对较未开发的新领域，对于重金属污染地区中针对具有经济和生态意义的重要农业或森林有害生物的生物防治策略的未来优化可能具有巨大潜力。©2020化学工业协会我们提出了一种“联合效应”假设，即与致病原药或仅重金属胁迫相比，昆虫病原体与重金属胁迫的组合可导致更高的总体昆虫死亡率。这是基于微生物的生物防治研究中一个相对较未开发的新领域，对于重金属污染地区中针对具有经济和生态意义的重要农业或森林有害生物的生物防治策略的未来优化可能具有巨大潜力。©2020化学工业协会这可能对未来优化针对重金属污染地区具有经济和生态意义的重要农业或森林害虫的生物防治策略具有巨大的潜力。©2020化学工业协会这可能对未来优化针对重金属污染地区具有经济和生态意义的重要农业或森林害虫的生物防治策略具有巨大的潜力。©2020化学工业协会
