Chronic Exposure to Polystyrene Microplastic Fragments Has No Effect on Honey Bee Survival, but Reduces Feeding Rate and Body Weight

Microplastics (MPs), in the form of fragments and fibers, were recently found honey samples collected Ecuador as well bees from Denmark China. However, little is known about how MPs impact bee health. To fill this knowledge gap, we investigated potential toxicity irregularly shaped polystyrene (PS)-MP on In first experiment its kind with bees, chronically exposed a well-established gut microbiome to small (27 ± 17 µm) or large (93 25 PS-MP at varying concentrations (1, 10, 100 µg mL−1) for 14 days. Bee mortality, food consumption, body weight all studied. We that chronic exposure has no effect survival, but reduced feeding rate weight, particularly 10 per mL, which may have long-term consequences The findings study could assist risk assessment pollinator

Exploring climate‐related gut microbiome variation in bumble bees: An experimental and observational perspective

Ecology, Год журнала: 2025, Номер 106(3)

Abstract Rising temperatures negatively affect bumble bee fitness directly through physiological impacts and indirectly by disrupting mutualistic interactions between bees other organisms, which are crucial in determining species‐specific responses to climate change. Gut microbial symbionts, key regulators of host nutrition health, may be the Achilles' heel thermal insects. They not only modulate biotic with plants pathogens but also exhibit varying sensitivity themselves. Understanding how environmental changes disrupt microbiome communities is a first step determine potential consequences for population responses. We analyzed gut bacterial six species inhabiting different climatic niches along an elevational gradient German Alps using 16S ribosomal DNA amplicon sequencing. investigated whether inter‐ intraspecific differences can linked species' niches, differ temperature, flower resource composition, likely pathogen pressure. A reciprocal translocation experiment distinct regions tested Bombus terrestris lucorum change short‐term when exposed new environments. Finally, we these heat cold wave scenarios within chambers disentangle pure temperature‐driven effects on from effects. Interspecific variation composition exceeded variation. Species levels stability, where stability defined as within‐group variance: lower indicated greater variance, predominantly observed higher elevations. Transplanted showed subtle adjustments, marked increase Lactobacillaceae upon exposure warmer regions; however, microbiomes did under laboratory temperature scenarios. conclude that could lead For example, less stable elevations might indicate increased pathogens.

Host-microbiome metabolism of a plant toxin in bees

While foraging for nectar and pollen, bees are exposed to a myriad of xenobiotics, including plant metabolites, which may exert wide range effects on their health. Although the bee genome encodes enzymes that help in metabolism it has lower detoxification gene diversity than genomes other insects. Therefore, rely components shape physiology, such as microbiota, degrade potentially toxic molecules. In this study, we show amygdalin, cyanogenic glycoside found honey bee-pollinated almond trees, can be metabolized by both members gut microbiota. microbiota-deprived bees, amygdalin is degraded into prunasin, leading prunasin accumulation midgut hindgut. microbiota-colonized hand, even further, does not accumulate gut, suggesting microbiota contribute full degradation hydrogen cyanide. vitro experiments demonstrated bacteria strain-specific characteristic particular genus or species. We strains Bifidobacterium , Bombilactobacillus, Gilliamella amygdalin. The mechanism appears vary since only some produce an intermediate. Finally, investigated basis wkB204, strain fully degrades overexpression secretion several carbohydrate-degrading enzymes, one hydrolase family 3 (GH3). expressed GH3 Escherichia coli detected byproduct when cell lysates were cultured with supporting its contribution degradation. These findings demonstrate host act together metabolize dietary metabolites.

Antibiotics-induced changes in intestinal bacteria result in the sensitivity of honey bee to virus

Environmental Pollution, Год журнала: 2022, Номер 314, С. 120278 - 120278

Antibiotics are omnipresent in the environment due to their widespread use, and they have wide-ranging negative impacts on organisms. Virus resistance differs substantially between domesticated Apis mellifera wild cerana, although both commonly raised China. Here, we investigated whether antibiotics can increase sensitivity of honey bees viral infection using Israeli acute paralysis virus (IAPV) tetracycline as representative antibiotic. Although IAPV multiplied lower levels A. cerana than mellifera, resulting decreased mortality (P < 0.01), there was no significant difference immune responses two species. Adult worker (A. mellifera) were treated with or without demonstrate prominent role gut microbiota against infection, found Lactobacillus played a vital antiviral cerana. In but not treatment reduced clearly bee survival increased susceptibility 0.01). Our findings revealed that long-term antibiotic had altered native microbiome promoted infection.
