“…The amount of E. coli detected in third instars in this study was lower than bacterial populations of larvae reported in other studies (Greenberg 1959a(Greenberg , 1962Radvan 1960) because larvae were only in contact with E. coli for 20 min. Stable ßy larvae were able to acquire as much or more bacterial cells than house ßy larvae from cultures of similar bacterial densities in all studies.…”

The persistence of Escherichia coli in artificially fed larvae was examined for up to 48 h after ingestion by house flies, Musca domestica L., and stable flies, Stomoxys calcitrans (L.). The rate of change in the E. coli load was similar for both species for up to 5 h after ingestion. Up to 48 h after ingestion, abundance of E. coli declined in immature house flies but remained constant in immature stable flies. When different E. coli concentrations were fed to larvae, the abundance of E. coli increased in stable fly larvae regardless of the initial concentration. The E. coli load in house fly larvae increased when larvae were fed a low concentration of bacteria, but it declined when larvae were fed a high concentration of bacteria. Survival of house fly and stable fly larvae averaged 62 and 25%, respectively, when reared on pure E. coli cultures. These observations suggest that house fly larvae digest E. coli and use it as a food source but stable fly larvae do not.

“…What mechanisms may underlie microbial transstadial maintenance, and how do bacteria may affect this process? The maintenance of S. cerevisiae yeasts and several bacterial strains throughout Drosophila metamorphosis are congruent with previous reports of the transstadial maintenance of extracellular microorganisms in Drosophilids [23,24,36,59], other Dipterans [53,[60][61][62][63][64][65][66] and other holometabolous insects [67]. During metamorphosis, microorganisms could maintain on either the inner or outer walls of the pupal chamber [68,69].…”

Influence of bacteria on the maintenance of a yeast during Drosophila melanogaster metamorphosis

Interactions between microorganisms associated with metazoan hosts are emerging as key features of symbiotic systems. Little is known about the role of such interactions on the maintenance of host-microorganism association throughout the host’s life cycle. We studied the influence of extracellular bacteria on the maintenance of a wild isolate of the yeast Saccharomyces cerevisiae through metamorphosis of the fly Drosophila melanogaster reared in fruit. Yeasts maintained through metamorphosis only when larvae were associated with extracellular bacteria isolated from D. melanogaster faeces. One of these isolates, an Enterobacteriaceae, favoured yeast maintenance during metamorphosis. Such bacterial influence on host-yeast association may have consequences for the ecology and evolution of insect-yeast-bacteria symbioses in the wild.

“…Even if the complete metamorphosis insects face an extensive change in microbiota between the larval and adult stages due to the gut replacement during pupation 48 , 49 , some studies reported that Salmonella persisted during the metamorphosis from larva to adult. In particular, this phenomenon was observed in A. diaperinus 21 , H. irritans 14 , M. domestica , and P. terrae-novae 13 (Table 4 ).…”

“…Seven studies investigated the persistence of Salmonella in Musca domestica (Diptera: Muscidae), five in Alphitobius diaperinus (Coleoptera: Tenebrionidae), three in Haematobia irritans (Diptera: Muscidae), two in Galleria mellonella (Lepidoptera: Pyralidae), two in Hermetia illucens (Diptera: Stratiomyidae), two in Tenebrio molitor (Coleoptera: Tenebrionidae), and one study in each of the following species: Calliphora vicina (Diptera: Calliphoridae), Carcinops pumilio (Coleoptera: Histeridae), Myzus persicae (Rhynchota: Aphididae), Phaenicia sericata (Diptera: Calliphoridae), Phormia regina (Diptera: Calliphoridae), and Protophormia terrae-novae (Diptera: Calliphoridae). Two papers investigated two different insect species 12 , 13 . The most commonly employed techniques to analyze the persistence of Salmonella were based on standard microbiology (cultural and biochemical) methods.…”

The consumption of insects as food and feed has been recently suggested as a possible alternative to the rising global food need, thus it is crucial to monitor any potential food safety hazards in the insect supply chain. The aims of this systematic review were to collect, select, and evaluate studies investigating the persistence of Salmonella in insects. We searched PUBMED, EMBASE, WEB of Science Core Collection, and Food Science and Technology Abstracts. In total, 36 papers investigating the persistence of Salmonella in insects (both holometabolous and heterometabolous) were included after screening. Regarding complete metamorphosis insects, the longest Salmonella persistence was reported in Phormia regina, in which the pathogen persisted for 29 days at 5 °C. Similarly, Salmonella persisted in the feces of Alphitobius diaperinus for 28 days. The incomplete metamorphosis insect showing the longest Salmonella persistence (>10 months) was Blatella germanica. Periplaneta americana excreted Salmonella via feces for 44 days until all the insects were dead. The retrieved data on the persistence of Salmonella can be useful for further analysis by risk assessors and decision-makers involved in the safety of insect-based food, contributing to defining the sanitary requirements and risk mitigation measures along the supply chain. The review protocol is registered in PROSPERO database (CRD42022329213).
