Black soldier fly (Hermetia illucens L.) larvae are capable of valorizing waste by converting it into insect biomass that can be used as animal feed, leaving undigested residue that can be used as soil enrichment. Evidence is conflicting over whether larvae fed substrate containing pathogenic microbes emerge uncontaminated. Studies also differ on which clades comprise the species' gut microbiome, and on whether and how diet affects these microbes. Using culturing and metabarcoding, the bacterial microbiota of black soldier fly larvae reared on two different kinds of food waste (postproduction soy pulp and postconsumer cafeteria waste) were analyzed, along with the microbes of their substrates. Little to no overlap was found between the wastes, the larvae, and the residues, but the larvae fed different foods had a significant percentage of their microbes in common. The data, in line with other works on this species, suggest the larvae have a conserved microbiota whose components vary geographically.
黑水虻（Hermetia illucens L.）幼虫能够通过将废物转化为可作为动物饲料的昆虫生物质来实现废物增值，同时留下未消化的残渣用作土壤改良剂。关于以含有致病微生物的底物为食的幼虫是否能无污染地羽化，证据存在矛盾。对于哪些进化枝构成该物种的肠道微生物群，以及饮食是否以及如何影响这些微生物，研究结果也各不相同。利用培养和元条形码技术，分析了以两种不同食物垃圾（生产后的大豆粕和消费者后的自助餐厅垃圾）饲养的黑水虻幼虫的细菌微生物群及其底物中的微生物。在废物、幼虫和残渣之间几乎没有重叠，但以不同食物为食的幼虫有很大比例的微生物是相同的。这些数据与关于该物种的其他研究一致，表明幼虫有一个保守的微生物群，其组成部分因地理位置而异。
