Beneficial soil microorganisms can contribute to biocontrol of plant pests and diseases, induce systemic resistance (ISR) against attackers, and enhance crop yield. Using organic soil amendments has been suggested to stimulate the abundance and/or activity of beneficial indigenous microbes in the soil. Residual streams from insect farming (frass and exuviae) contain chitin and other compounds that may stimulate beneficial soil microbes that have ISR and biocontrol activity. Additionally, changes in plant phenotype that are induced by beneficial microorganisms may directly influence plant-pollinator interactions, thus affecting plant reproduction. We explore the potential of insect residual streams derived from the production of insects as food and feed to promote plant growth and health, as well as their potential benefits for sustainable agriculture.
有益的土壤微生物有助于对植物病虫害进行生物防治，诱导对攻击者的系统抗性（ISR），并提高作物产量。有人建议使用有机土壤改良剂来刺激土壤中有益本土微生物的丰度和/或活性。昆虫养殖产生的残余物（粪便和蜕皮）含有几丁质和其他化合物，这些化合物可能会刺激具有ISR和生物防治活性的有益土壤微生物。此外，有益微生物诱导的植物表型变化可能直接影响植物与传粉者的相互作用，从而影响植物繁殖。我们探索了作为食物和饲料生产的昆虫产生的残余物促进植物生长和健康的潜力，以及它们对可持续农业的潜在益处。
